Every morning we thank the heavens for our love European cars, and that we’re blessed with so many expert tuners. To celebrate our good fortune, we try to gather the very best tuning shops and finest European machinery for three days of power and speed.
If you’re a regular reader, you’ll know the format well. Although it looks like a grudge match, and while the teams do compete against one another, we differentiate them in front-, rear- and all-wheel drive classes. However, we need to stress this isn’t strictly a competition since the cars aren’t built to a specific formula. As a result, they’re not really comparable to another, but this is your chance to see how the various modifications perform in real-world tests. So if you’re thinking about tuning your GTI or M3, for example, you might like to consider some of the engine or chassis mods featured here.
The Tuner GP isn’t as much a competition as a battle for pride. It’s the perfect opportunity to examine specific tuning packages and discover whether they meet the tuner’s claims. And while the team with the best numbers has something to brag about, that’s not the whole story. For example, the car that wins each of the three disciplines is likely a highly focused track car that might not translate well to the street. But by measuring power, acceleration and track times, you can see which package delivers the most overall, or in the specific area you want. In other words, eurotuner GP (etgp) allows you to browse tuning conversions under the harshest conditions and decide what modifications or even base vehicle would work for you.
In previous years, we’ve seen a majority of vw tuners, but with the Audi S4 often taking top honors thanks to its twin-turbo V6 and AWD traction. However, 2011 (etGP11) was the first time we’d had BMW tuners in the majority, which surprised us because in past years we’ve often had none! With high-revving supercharged engines, rear-wheel drive traction and good chassis, we were expecting some upsets this year.
etGP is a test of speed, power and balance. We scrutinize the cars on the dyno for outright power, the dragstrip to reinforce those numbers, and the road course to see how the total package performs under sustained pressure.
As before, the competitors we divided into front-, rear- and all-wheel drive classes so we could recognize the top cars in each class.
Like every etGP, the rule is there are no rules – except no nitrous in the engine. We do this to allow the tuners to display their craft, but as conversions become more ambitious, it looks as if we may have to introduce certain restriction next year. Currently, you can do any tuning any time. This has led to some teams loading different software files and even swapping turbos to best suit the demands of the day. While this indeed shows their skills and understanding of the event, we will probably go to a more rigid structure in 2012.
And because some teams had an advantage with tire choice in previous years, we now supply all teams with Continental ExtremeContact DW tires. This is one of our favorite high-performance tires, able to stand up to the abuse incredibly well, which is why we’ve used them for the last two years (see sidebar).
On the Wicked Motorsports dyno day, teams were allowed three pulls and could tune in between. We always expect high numbers and despite a few problems with the dyno itself, we weren’t disappointed.
For the drag racing, we returned to California Speedway where there’s no restriction on the number of runs a competitor can take in the three-hour session.
We also returned to the road course at Streets of Willow because it’s one of our favorite SoCal tracks. With its tight turns and high-speed corners, it’s a great test of chassis balance over engine power. We prefer it to some of the faster tracks because it gives the less powerful teams a chance to shine, rather than the more powerful cars blowing them away on the straights.
So keep reading as we tell you how each team did on the dyno, drag and road course. We also have a profile of each team as well as the overall results and a spec list for you to better understand what went into building these remarkable cars.
Continental ExtremeContact DW
Specifying a control tire for eurotuner GP means we can focus on what parts the tuner has fitted, rather than the rubber he’s chosen. This gives us a better indication of how the components are working together. Yet it’s vital for us to choose rubber that’s up to the task and doesn’t leave the competitors scrabbling for grip.
We were very fortunate to again be supported by Continental Tires, and need to thank them for making it all happen.
Once more we had decided to run the latest ExtremeContactTM DW tires for the second year in a row, because we know how well they perform from our own tests and last year’s event. In fact, they won our last Tire Test (et 12/09) that compared ten of the latest high-performance tires in both wet and dry conditions. The Conti DW was the overall winner and its abilities in mixed weather conditions were appreciated by GP competitors who experienced some rain on the day of the dyno test.
In our product test, Turner Motorsport’s racecar drivers commented on the DW’s good braking grip, excellent turn-in response and fantastic overall grip in both the wet and dry. So it was this overall consistency and predictability that put it in first place.
During the GP, the same attributes are appreciated on the track, where it needs to keep the car stable under very high braking forces, while also providing strong and consistent cornering ability. What’s more, when the tire does finally let go under severe provocation, they respond predictably to give the drivers plenty of feedback.
During its manufacturer, Conti ensures the DW (meaning Dry and Wet) provides both a lower rolling resistance and improved tread life than its competitors. It has a 340 UTQG rating, which means they should last many thousands of miles under normal conditions. What’s more, there are different indicators within the tread blocks to alert drivers to when the tires have exceeded their optimum tread depth in both dry and wet conditions.
Due to a date conflict, etGP11 actually began at the dragstrip this year, but we’re going to look at the dyno results first because they should be an indication of what to expect at the strip.
In a change of venue, Wicked Motorsports in Los Angeles offered its all-wheel drive Dynocom DC5000 dynamometer to us. The company is best known for its Audi S4 tuning and had entered a car in a previous GP event. However, it’s moving more upscale and the workshop boasted several Porsche 911s, Nissan GT-Rs and even a Spyker.
As it transpires, the dyno was relatively new but Mike Ghaemi showed enormous patience as we learned its idiosyncrasies with each car. They even provided a lunch for the teams in the shop’s waiting room that conveniently boasts a pool table and TV.
Our biggest problem was getting consistent results with so many different vehicles and high expectations from each tuner. We did experience several anomalies, such as when manually setting the RPM for each car. This had to be triggered at exactly 2500rpm, but because some cars didn’t have accurate tachos, it threw off the torque readings.
We also experienced spikes in the power curves that gave extraneous readings. For example, some teams claimed to be 150hp down on what they expected, while others were more than 100hp up; some couldn’t spin the rollers past 90hp; and another got no reading at all.
Bear in mind, each tuner tests his car days before the event to ensure everything is running correctly, often on their own dynos, so they have a good idea of what to expect…
Frankly, it was rather inconsistent, in part caused by not having enough time with each car or experience on the rollers. However, Mike and his Wicked crew stuck with us, finally running the last car at 10pm after an early 8am start!
As a result, we’re not going to reveal torque numbers here because several readings were unreliable. It’s possible to calculate torque from the power curve, but because the RPM readings were skewed in some cases, it wouldn’t be accurate enough for our purposes.
Undoubtedly, the dyno is capable of measuring power and torque but it was a big ask for Wicked to get through this many cars in a single day with new equipment.
For reference, we’re also going to list the hp number each team thought they should get because several tuners were unhappy with the outcome. What’s more, by cross-referencing the dyno numbers with the quarter-mile times, you should be able to see whether the numbers are realistic. Obviously, you have to factor in traction issues for the front- and rear-wheel drive vehicles, but the drag times do highlight that several BMWs, in particular, were likely more powerful than the dyno numbers suggest.
The front-wheel drive class has been decimated recently, with only Raffi and Vic Kazanjian from Euro Sport Accessories persevering with it. They had made a few tweaks to the ’01 VW Golf they built for last year’s event and were hoping for big things.
Their in-house dyno had seen as much as 320hp at the wheels (whp) from the 1.8T with GT2871R turbo and big injectors on GIAC software. So we were all slightly perplexed when it only produced 170whp!
After running more cars, we decided to re-test the ESA Golf and it rose to 337whp. Confusingly, this is more than they expected but, given the problems we’d encountered and the differences between respective dynos, we decided to go with it.
The AWD class is where we usually expect the fireworks, and this year was no different, with Bluewater Performance, in particular, building an incredible Rabbit 2.5 turbo for the event. On the dyno it had to run in FWD, which created potential traction problems, but would possibly show more power thanks to there being less drag.
After a few false starts with the dyno, the Rabbit screamed to 619whp. This was slightly off the predicted 650hp they’d previously seen, but the Bluewater team was happy with the number. Given the way it produced such an impressive figure, this car was clearly going to be a real contender on the track events.
Eurocode Tuning was a last-minute entry after it managed to find a suitable clutch for the car only days before. They were slightly anxious about whether it would hold up, since this was the first time they’d used it, and had burnt through a pile of others in the past few months. However, they spun the rollers to 398whp and seemed relatively content with the result.
Forge Motorsports was a new contender in etGP and didn’t know quite what to expect. Its Audi TT S had been trailered from Florida for our event, sporting graphics after its appearance at H2Oi.
With a number of bolt-on tuning parts and many of the company’s own components, they were confident of getting into the 300hp mark and were pleased to see 317-AWD-hp flash onto Wicked’s computer screen.
Finally, the patience of Matt Baumann from Raven Motorsports paid off when his A4 1.8T quattro with 2.0L stroker kit was strapped to the dyno. Expectations were high because the enlarged engine with big-valve head, Cat cams, big injectors and Garrett GT3076 turbo was rated at 415hp.
Unfortunately, this was one of the biggest losers on the day, only measuring 305hp despite sounding like a stone-cold killa. A slipping clutch after the previous day’s drag racing was found to be the culprit, so Matt rushed back to his workshop to spend the night swapping the clutch.
This was probably the most competitive class, with former etGP champions 034Motorsport and Groma Fab battling for honors, albeit in different cars from their winning years.
It’s fair to say 034Motorsport was perhaps the best-prepared tuner at our event, building its own mid-engined S4 V6 single turbo-powered Mk4 Golf GTI especially for the GP. In its first year they narrowly missed overall victory with some teething problems, so they were back for gold.
Being first to arrive, the GTI was strapped to the dyno but that’s when the problems started. The car simply couldn’t record any numbers. The dyno didn’t seem to know a car was running.
After hours of problem solving, we pulled it off the dyno and continued to look for a resolution with other cars. As a result, 034 patiently waited about 13 hours before finally getting on the dyno.
Having seen 807hp on their own in-house dyno, they predicted 700hp on the Wicked rollers and nailed it on the third run with a figure of 716hp. This was the most powerful car on the day, and you always feel 034 has something in reserve if another tuner gets close enough to challenge them. But with 100hp over the nearest rival, we called it a night and went home.
Behind the GTI were a phalanx of six BMWs, all within 60hp of each other despite different engine sizes and layouts. Up first was the E92 M3 from Sonic Motorsport with its stage two Active Autowerke supercharger conversion. This team was hoping for 650hp at the wheels but left rather dejected with only 486hp.
We’d suggest the two E92 teams were a little optimistic but the measured power didn’t seem to reflect what the cars were capable of. This also applied to the european auto source M3 with its VF-Engineeering blower, which only put down 457whp. With the tuner regularly seeing about 100hp more on its in-house dyno, they were also disappointed. Check out the quarter-mile times for another indication of what the cars are capable of.
The dark horse in etGP11 was the BMW 2002 from Groma Race Fabrication. As last year’s winners, they wanted to do well and had surprised everybody by turning up with a 36 year-old car. However, the turbocharged M20 325i engine under the hood meant they were confident of a good showing, and pushing the rollers to 433hp proved they were on the right track.
Unfortunately, it took a few too many runs to get the dyno to read properly, initially claiming the engine was developing 90hp. As a result, Groma suspect the engine overheated and possibly blew the head gasket, resulting in problems on the track day…
Close behind Groma was the Berk Technology BMW 135i. As a time attack contender, the team cared little about the dyno last year but had made more preparations for etGP11. As a result, the engine spun easily to 423hp, which was considerably more than the team’s original estimate.
Just 2hp behind them was the VF-supercharged M Coupe from LTBMW. This car was a little down on estimations but developed healthy power for such a light car.
In turn, the ESS-supercharged E46 M3 from Platte Forme AG was only 1hp down with 420whp. Built as a time attack car, like’s Berk’s 135i, neither team was as concerned by engine output as lap times…

Wicked Motorsports was founded in ’05 by Audi fan Mike Ghaemi. He quickly became known in Southern California for building fast B5 S4 models, appearing at local drag strips and even a previous etGP. The shop is located in Los Angeles and features the latest tools and equipment, including its new Dynocom AWD dynamometer. It also has a team of experienced technicians to work on European cars, carrying out general servicing work or fitting performance parts.
Another selling point is the company’s discount scheme for genuine VW/Audi parts, as well as a warranty on fitting, free local rental or shuttle plus a free towing service in certain cases. The shop is open 9-5 weekdays and Saturday by appointment.
So if you’re in the Los Angeles area, and need an experienced European performance center, visit Wicked Motorsports (wicked-motorsports.net).
Unlike last year’s disastrous rainfall at the start of our drag racing competition, etGP11 was greeted by low cloud and a slight fog. This damp, dense air wasn’t great for traction but would certainly help engine power.
With three hours on California Speedway’s quarter-mile track, the competitors wasted no time setting some early times. First up was Eurocode Tuning, with its supercharged ’11 Audi S4 V6 sounding particularly obnoxious. The team had decided to remove its Neuspeed exhaust and replaced it with a torque tube.
This essentially meant they had no silencing on the car and while the V6 screamed like a racecar, it hurt your ears as it passed by at full revs. The team later admitted they weren’t sure the plan was giving more power but persevered with it.
The first quarter-mile time was a very respectable 12.4sec. They spent the rest of the session completing 17 full-power runs, which spoke highly of the brand-new and untested clutch they’d been concerned about before the event. During the next three hours, they shaved tenths of their time, eventually finishing in fourth place with a respectable 12.138sec quarter at 114mph.
This threw the gauntlet down for the remaining AWD competitors, with Forge Motorsport responding immediately. Equipped with new Revo engine software and HPA’s stage 3 DSG software, the TT S was able to launch and shift with surprising force.
With a first run in 12.25sec, it was apparent the lighter TT S was going to give the S4 some competition. The second run produced a 12.099 at 112mph and it was game on. Both Eurocode and Forge chased this time all morning, never able to beat it, but coming tantalizingly close in the process. Forge felt it could actually challenge for the lead but was never able to drop into the 11sec bracket.
The matte-wrapped Audi A4 1.8T from Raven Motorsports was late to the party, but owner/builder/driver Matt Baumann set about the task of attempting to run with the other quattros.
His first pass was 13.7sec but it was clearly the tip of the iceberg as the driver discovered the available grip from the Conti DW tires, the best shift points, etc.
Subsequent times were slower by a few tenths, but the launch technique was improving with every run. With persistence, the car set a very respectable 12.865sec at 110mph but thereafter it developed a misfire and suffered clutch wear during the course of its 15 runs.
That only left Bluewater Performance and its custom-built Mk5 Rabbit turbo AWD to set a time. Despite its traction advantage, all four wheels were spinning through first and second gears as the car launched with a ferocity never displayed by any previous Rabbit (you should definitely watch the video for this display!).
First time down the quarter-mile it broke the timing lights in 11.8sec at 127mph, and we all knew we’d witnessed greatness. In fact, this was almost equal to the time set by Bluewater’s R32 on the same tires in last year’s event – a feat that would give them the drag racing win in etGP10.
However, there was more to come and the next pass produced a time of 11.757sec at 128mph. We were excited at the prospect of seeing these times fall when the team reduced the tire pressures and reset the launch control on the United Motorsports software. They also increasing the boost pressure to 25psi but the next time was mysteriously slower.
The team did one more run that day but it didn’t end well. Having turned up the boost, it blew off a hose. The result was a noisy flywheel. After taking the car to Groma’s shop that night, they stripped it down to discover they’d sheared three bolts off the flywheel and it had welded itself to the crank.
Having struggled to remove the flywheel, they fixed it on with three ARP bolts and three more from Home Depot before physically welding it to the crank to keep it in place.
With a paddock full of supercharged BMWs and 034’s custom-built mid-engined, RWD GTI yet to run, the Bluewater Rabbit didn’t look safe at the top. As it’s name suggests, 034Motorsport approaches everything as if it were a professional race. The team uses headsets, timing, datalogging and more to ensure consistency and reliability.
With company owner Javad Shadzi at the wheel, the VW launched incredibly hard but the spinning rear wheels meant it was an entertaining run rather than fast. Forced to lift off the throttle to regain grip, he crossed the line in 12.8sec.
Traction was a similar issue on the second run, despite tire pressure and suspension changes to control it. With a little more boost, the car got wheelspin at the start and again at the top end. In fact, the rear broke loose at over 130mph, with Javad needing to counter-steer and actually drift across the finish line. He knew the run would be fast, so didn’t want to get out of the power, but the cost of spinning at that speed would have been high.
The GTI broke the beam in 11.885sec at 134mph and the fight was on. Not only were they hopeful to beat Bluewater’s 11.76sec time, but were confident of 11.5sec following pre-event testing.
After another hard launch on the third run, it suffered excessive wheelspin but then a sickening metallic sound. With a loss of power, the driver lifted off and coasted down the strip.
After a quick strip down, they found a tooth had broken off the final drive. The solution was to take the car to Wicked Motorsports where they had three B5 S4 transmissions in stock. Although the car uses a FWD Audi 01E tranny, they worked overnight to fit the quattro tranny, weld the center diff, install the limited- slip diff and have the car running the next day.
The result was lost sleep and another drag racing win for Bluewater, who took first place last year after 034 broke a driveshaft flange on the GTI’s first outing.
The fastest BMW was the supercharged E46 M3 from Platte Forme. We had expected the more powerful E92 M3s to dominate this division but the lightweight six-cylinder took the honor with a 12.241sec run at 119mph. The team later admitted they were confident of breaking into the 11s but “were too busy chatting and lost track of time!”
Just two-tenths of a second slower was the VF-supercharged E92 M3 from european auto source. The team started cautiously, struggling for grip and trying to find the best launch technique. They started in the mid-14s and dropped to 13sec by the sixth run. After that, they nailed 12.298sec at 121mph and remained consistently in that region for the rest of the morning. With its civilized exhaust note and relative lack of drama, the car ran reliably all session.
With its car set-up for the road course, Berk Technology only completed three runs on the strip. They recorded a 12.995 at 112mph on their first run and eventually settled for that, not wishing to damage the clutch in a discipline they knew the car wasn’t built for.
That put Groma Race Fabrication in ninth place on the day with a time of 13.214 at 111mph. Interestingly, the 2002 time matched their fourth place finish time in the E36 M3 turbo Groma entered last year.
With relatively narrow tires and lots of power, it took the team a few runs to figure out the launch. Initially, it was very sideways as driver Mono Agulian fought to gain traction in the lower gears, almost looking like he was going to spin. However, he soon came to terms with it and got a clean launch to record his time but was unable to repeat it thereafter. “I missed a shift, had wheelspin and hit the rev limiter,” Mono lamented after one run. “I made every possible mistake!”
With so many experienced drivers, it was brave for Calvin Wongkar and Alan Chaces from Sonic Motorsport to attempt to drive the Active-supercharged M3 themselves when they had no prior experience. Unfortunately, this meant the car never realized its full potential as both struggled to refine the launch technique and control wheelspin. On several runs, the driver was forced to lift off the throttle to control the car, losing valuable time. On other runs, the car was sideways as they attempted to drive through the wheelspin.
We always say a good driver is the one of the most important aspects of a team’s tuning for etGP, and sadly Sonic was proving us right. However, their perseverance saw the times improving by large chunks until fate dramatically intervened.
After a burnout to warm the tires, the Sonic M3 pulled up to the line but was overtaken by its own rear wheel! Five of its titanium studs had sheared in the hub, leaving the car sliding on its brake rotor.
“I’ve been here since ’95 and never seen that before!” declared a track worker as we all agreed it was better to lose a wheel at the start than the finish. It’s also worth noting that if you’re going to save weight, your wheel bolts might not be the place to start…
After finding some replacement bolts, the car was removed from the track and the team decided not to try to improve on its best run of 13.258sec at 110.68mph.
The final RWD car was the supercharged M Coupe entered by LTBMW. The car only made six passes, culminating in a best time of 13.411sec at 109mph after struggling with lots of wheelspin in the lightweight coupe.
That leaves our only FWD entrant in last place, bringing up the rear with a time of 13.872sec at 106mph. Interestingly; this was 0.4sec quicker than Eurosport Accessories’ best time last year, showing their steady development with the car. And while it was launching surprisingly hard, it seemed almost inevitable that a driveshaft would snap at some point…
Having replaced one of the original driveshafts at etGP10, the remaining 161,000 mile shaft snapped at etGP11. Fortunately, the guys were prepared for it and had a spare in the trailer. It took them about 30min to replace and they were back on the startline looking to improve. Yet given the inherent traction disadvantage of FWD, being less than 0.5sec behind a considerably more powerful BMW must be considered a victory.

FASTEST LAP COMPETITION
Streets Of Willow
For all the effort every competitor puts into the dyno and drag events, each of them will admit its the road course day they really want to win. Moving the event from mid-July to late October has helped the competitors since the temperatures are about 30˚F lower, giving the engines, brakes, tires and drivers better conditions.
Although slightly cold in the morning, the day warmed to the mid 70s and remained fairly constant throughout the day, giving everybody a fair crack at the track.
As usual, we split the teams into three run groups, with each getting three 20min practice sessions throughout the morning. This was to allow them time to set-up the cars and familiarize themselves with the track.
After lunch, each team got three solo timed laps to set their best time. Unfortunately, some of the drivers were cutting corners and kicking dirt onto the track, handicapping the later cars, which could have been a factor in some results.
Unfortunately, we had some problems with timing transponders in the morning. That meant we didn’t get many lap times from the teams to gauge how everybody was doing.
Overall, the competitors seemed pleased with their progress and were using manual stopwatches to track their cars’ progress.
The only car with major problems appeared to be Bluewater’s Rabbit, which was overheating on the track. Professional driver, Mark Smith, had been brought in to set the times. As the SCCA Pro Solo National champion, he was learning the new track fast, but the cooling issues meant he only got four laps at a time. Yet he was improving with every session.
Most of the other teams were complaining that our extended dyno session didn’t give them enough time to prepare the cars for the track. However, Berk was ready for action. After last year’s disastrous oil fire ended their day early, the team wasn’t going to be disappointed again.
In addition to some aggressive new aerodynamic parts, they’d also put chassis engineer Carl Rydquist behind the wheel. He’s a European endurance racer and working with KW had been able to optimize the suspension set-up to get the most out of the Conti ExtremeContact DW tires everybody was using.
As the best (and only!) FWD car in the event, Euro Sport Accessories had set itself the goal of beating last year’s best lap. This had been a 1:28.9 but unfortunately they were unable to match it.
With company owner and experienced racer, Raffi Kazanjian at the wheel, his best time was 1:29.661 despite a bigger turbo and general fine-tuning.
It’s difficult to say why the car was slower this year but possibly the cooler temps didn’t suit the Golf so well, with the tires not reaching their optimum level…
The AWD class is traditionally where we look for our road course winner, and all eyes were on the assembled quattros plus Bluewater’s Rabbit. Slowest of the group was the Raven Motorsport A4 1.8Tq. with a best time of 1:29.157 they were ninth on the day with Matt Baumann at the wheel. He was clearly having fun and set a very respectable time but you’ve got to wonder if a pro driver couldn’t have found a bit more…
One step above him, but more than one second faster, was the Audi TT S from Forge Motorsport. With a time of 1:27.802, the coupe was in the same bracket as some very powerful cars. Part of its performance can be attributed to the skilled feet of Clint Boisdeau, a part-time track instructor who definitely got the best from the 2.0T engine. They were again impressed with the HPA DSG software that ensured the car wouldn’t kick-down or change up without the driver commanding it, giving Clint more control in the corners.
Despite an impressive lap time of 1:27.045, the team from Bluewater Performance was slightly disappointed. They were hoping to make a clean sweep of the entire GP, with domination of the road course high on their priorities. Unfortunately, the engine cooling problems meant the boost was retarded to 15psi (compared to 25psi on the dyno), so we never saw what it could really do. The driver was happy with the suspension set-up, but Gabe Adams and the Bluewater team are determined to return next year with better aero, possibly a widebody and an ice box to help with engine cooling.
The fastest car in this class was the Audi S4 from Eurocode Tuning. This is remarkable since it was in pieces a few days earlier, yet ran faultlessly throughout the event.
A big factor in setting the best time of 1:25.727, which put them third overall on the track, was the presence of Ian Baas behind the wheel. A regular driver for APR Motorsport in its Grand-Am S4, he was the ideal candidate to get the best performance from the engine and chassis. Despite being new to the track, having gravel on the course and some minor suspension problems, Ian showed what the S4 could do in the hands of a professional.
With the shocking news that an AWD car hadn’t set the fastest lap time, you can deduce that the winner must have had 2WD. And with so many powerful BMWs on the track, it certainly seemed like any of them could have claimed victory.
At the bottom of the pile was last year’s overall victor, Groma Race Fabrication. Its ’75 BMW 2002 set a time of 1:34.484, which was a long way off the 340whp E36 M3 turbo they entered in etGP10. Another factor was touring car driver, VJ Marzayan, who was absent this year. Instead, Groma’s Mono Agulian was at the wheel and struggling with the old girl.
Up against such modern machinery, the 2002 was always the underdog. It was also set up for 15" wheels, but we could only supply 16" tires. This meant the suspension had to be raised, affecting the geometry. There were also rubbing issues because the fenders didn’t have much room. As a result, the tires were relatively narrow and struggled for grip.
The team also lost an opportunity to tweak the suspension when they opened their shop to Bluewater after the flywheel sheared off. As is a GP tradition, teams help each other; offer advice, loan tools and even share drivers at times. The guys at 034 have always been very helpful, with Groma, Euro Sport, Eurocode et al happy to help their fellow competitors. So despite a disappointing result, the Groma crew was pleased with the car and its performance.
Just ahead of them in 11th position on the day was the Sonic Motorsport E92 M3 that recorded a best lap of 1:30.264. Driver Daniel Tjiputa had never seen the track before and started slowly, coming to terms with understeer problems. However, he built up speed during the day but we have to think the car had more to offer. The european auto source M3, for example, with similar mods was almost 2.5sec quicker per lap…
Next up was the LTBMW Z3 M Coupe with a 1:27.729 lap time. This was respectable considering they were experiencing problems with second gear, but the ace up their sleeve was Grand-Am prototype driver Gene Sigal, who pushed the VF-supercharged Z3 around as fast as it could go.
At Gene’s request, they’d disconnected the rear sway bar and adjusted the KW dampers to improve the handling to good effect. In hindsight, they might have benefited from removing the audio system as well...
The sixth fastest road course time went to european auto source who got round in 1:27.713. This was especially gratifying for the team since they’d driven to each event, done little more than adjust tire pressures and driver Jordan Yost had never seen the E92 M3 before. However, he did know the track, and that’s a big factor in a good time. Overall, they were happy with the performance from the VF blower, although they might want to check the condition of the front splitter that was scraping the ground in tight corners.
Fourth fastest overall was the ESS-supercharged E46 M3 from Platte Forme, which recorded a 1:25.887. With its large splitter, huge wing, stripped interior and full cage, we’d have been disappointed if this wasn’t at the sharp end of the competition.
It was driven by Terry Liu, who had to get permission from his professor to miss school, and left early to make class. The team made no changes to the car and were impressed by the ESS Tuning conversion, which ran flawlessly.
And the winner is…
Fastest lap of the day and RWD class winner went to Berk Technology with its BMW 135i. With an impressive time of 1:24.694, it was almost 1sec quicker than last year’s fastest. This was particularly rewarding for the team since etGP10 was cut short when an engine fire, caused by a minor oil leak, melted the wiring harness and put the 135i out of action before it had completed one lap.
Because the car is built for time attack events, it’s focused on one fast lap, so it’s perfectly tailored for etGP. And with its new aero components and chassis development, it was always a leading contender for the win. In the competition as a whole, the team placed higher than expected since they only wanted the fastest lap trophy.
Finishing about 1sec behind Berk was 034Motorsport and its 700hp mid-engined GTI, which lapped in 1:25.644. After dominating the dyno but breaking on the dragstrip (as they did last year), the road course is where the team always wants to win.
Having swapped the transmission, the team did four laps in practice and parked it until the timed session rather than risk a problem before it could be timed. The suspension set-up was basically the same as last year with some minor tweaks, and driver Christian Miller had a push-to-pass button on the steering wheel that gave him 21psi boost for the straights, reverting to 6psi for the rest of the lap.
By having the most powerful car, finishing second overall in the drag racing and the road course, the 034 GTI finished the event as the best RWD car and the overall winner (not that it’s a competition…). Although they wanted a clean sweep of all the disciplines, the car performed consistently despite drivetrain damage that might have seen other teams retire. However, the resilience and preparation shown by 034 meant they walked away with two trophies from etGP11.
We also have to recognize an amazing effort from Bluewater Performance, who also suffered mechanical problems but came through to win the AWD class and finish second overall in the competition.
In third place, was Berk Technology with a consistent set of results, as we mentioned. They were followed by Eurocode Tuning, european auto source and Platte Forme. Finally, we must recognize Euro Sport for utterly dominating the FWD class!

2007 VW Rabbit
Location: Westminster, CO
Best AWD dyno
Best AWD drag
Bluewater Performance specializes in VW/Audi performance installation, fabrication and aftermarket tuning parts. It’s best known for high horsepower R32 VR6 builds, such as the turbocharged car they entered into etGP10.
Recently, owner Gabe Adams was inspired by the potential of the 2.5-liter five-cylinder, which he plans to push further than anybody has done before. So a ’07 Rabbit was the ideal car, but they knew AWD would be needed to put down 600hp.
With a plan to build a Rabbit that would sweep etGP11, the team fabricated an AWD system in just two months using an Audi TT quattro transmission paired to a ‘08 R32 Haldex rear diff.
When it came to the drag event, the AWD system launched the Rabbit down the quarter-mile stretch in 11.757sec at 128.09mph, giving them the win.
On the dyno they slipped into second place with a pull of 619hp. Gabe had thought about designing the engine to provide quick access to changing the turbo for different disciplines to put down bigger numbers, but couldn’t fit it into the short build time.
When it came to the track event, Gabe mentioned the Rabbit handled better than the previous ’04 R32 thanks to the suspension layout and Haldex set-up.
However, the driver hadn’t seen the course before, and cooling issues limited him to a handful of practice laps at a time.
For next year they plan to address the cooling issues with an icebox and bigger radiator for starters.
2010 Audi S4
Location: Torrance, CA
Best AWD track
Eurocode Tuning is dedicated to Audi, Porsche and VW tuning. The shop also develops and tests its own new parts, along with building high-performance cars. Some of these development parts were on the B8 S4, including long-tube headers, Kreuz aluminum drivetrain stabilizer, adjustable sway bars with drop-links and an adjustable short shifter.
Eurocode removed the exhaust at the dragstrip to improve its times. And as the S4 screamed down the quarter mile, it ran a 12.138sec at 113.97mph, putting them in fourth position overall.
The following day the team was pulled over by the police for driving to the dyno day without passenger seats and numbers on the doors. Fortunately, company owner David Sarabi was able to talk his way out of a ticket and put down a 398hp.
To remain competitive at the track, the keys were handed to friend Ian Baas, who’s familiar with the B8 S4 platform, which he’s currently developing with APR for Grand Am racing. Finishing third at Streets of Willow with a time of 1:25.727, they secured fourth place overall in etGP11.
2009 Audi TT S
Location: Orlando, FL
Forge Motorsport is a British parts manufacturer that has been in the US for eight years. This was its first year competing in the GP, having driven up from Orlando for our event.
The company’s catalog offers a range of items to transform many cars, including VWs and Audis using bolt-on parts and software.
To compete, they entered an Audi TT S for its tunable engine and lightweight chassis. Making the 2565-miles journey, they got accustomed to the higher elevations with a few sightseeing tours.
When it came to the first day of competition, Forge’s plan was to break into the 11sec quarter mile times, and HPA’s stage three DSG software was a key component in achieving consistent results. This earned them third place overall with a 12.29sec quarter-mile pass. Unfortunately, the team ran out of time before achieving their 11sec goal.
They worked with Revo to obtain stage 2+ software that achieved 317hp on the dyno.
The DSG software also came into play at the track. In manual mode, the car holds the gear selected, no longer up-shifting or kicking down gears of its own accord. Using experienced driver Clint Boisdeau, he was able to set a 1:27.802 lap time and show what was possible with a mildly-tuned TT S.
2000 Audi A4
Location: Long Beach, CA
This is Raven’s second etGP, and Matt Baumann was looking to improve on last year’s fourth place overall. The company consists of four staff that are both factory -trained and aftermarket-experienced. Handling everything from oil changes to performance builds, they entered etGP11 with the same daily-driven Audi A4 as last year. This time they added a Garrett GT3076 and Stasis/Ohlins 700/900 suspension, making it more suited to the demands of the event.
Matt also prepared himself for etGP11 by conducting two practice weekends at Streets of Willow to learn the course and the car.
When it came time for the drag event, Matt ran a 12.865sec quarter mile at 110.07mph. Compared to last year, he lost a few tenths with clutch issues that would become more pronounced on the dyno day.
Replacing the clutch before the track day, Matt surprised himself with his lap times. He chose to go with 245/35 R18 Continental DW tires instead of last year’s 245/40s. The low-profile sidewalls appeared to pick up better lap times and the extra practice dropped his time from a 1:35sec last year to a best of 1:29.157 in etGP11.
Euro Sport Accessories
2001 VW Golf 1.8T
Location: Anaheim, CA
Overall FWD winner
Euro Sport Accessories started in 1988 and continues to design, develop and test parts for VW/Audi cars. Based in Anaheim, the shop sells intakes, exhausts, stress bars and other performance parts as well as suspension compents and has an in-house dyno for software installs.
The company has been involved in etGP since the very beginning. During that time they’ve entered everything from a Mk1 Rabbit to Ford Focus, and this year returned with the Mk4 Golf 1.8T that was originally custom-built for last year’s event.
After making half a dozen runs on the strip, the team broke an axle. Raffi Kazanjian wasn’t surprised, commenting that it was the original axle from 2001 and had logged 161,000 miles since then. They had a back-up ready, but with limited time for more runs after the repair, they were happy with the number.
The dyno gave a better-than-expected result with 337whp. While on track, the team made several improvements from last year. This included new mounting points for the turbo, which rattled its bolts loose last year. The car also had a new front splitter that increased high-speed stability.
The plan was to get the Mk4 to break into the 1:30 lap times. Successfully recording a best time of 1:29.661, Raffi said, “It’s ready to go again with race gas in the tank!”
2001 VW GTI
Location: Fremont, CA
Best RWD dyno
Best RWD drag
This year 034Motorsport’s goal was to sweep the entire event. The shop focuses on providing parts to the dedicated tuner, including its own engine management, turbo tuning and chassis set-up, plus the manufacture and engineering of many in-house performance parts.
The team again brought its purpose-built mid-engine, S4-powered, rear-wheel drive ’01 GTI that competed last year. The VW is an extreme example of what the shop can provide to customers and was featured in et 12/10 as well as online at eurotuner.com
Having spent three days testing before the GP to resolve any bugs, 034 was fairly confident going into the drag racing. With company owner Javad Shadzi at the wheel, he completed one warm-up run before the rear wheels broke loose at 130mph on the second.
Javad made the decision to stay on the power, drifting across the traps and finishing with a 11.885sec pass at 134.438mph. Looking to better the time on the third run, the ring and pinion broke a tooth and ended their session.
Working late into the night, they sourced an Audi S4 quattro transmission and welded the center differential for their RWD application. They also kept the same GT4202RS for the dyno as the drag, later switching to a smaller GT35R turbo with better response for the road course. They’d spent five hours tuning the GT4202RS and had seen 800hp before the event. The dyno eventually read 716whp, which was a little shy of expectations but still earned them the overall win on the dyno.
With two out of three events in the bag, they wanted to repeat last year’s lap times and secure the overall win. Despite an exciting spin in turn four, 034’s shop manager, Christian Miller, came through with a time of 1:25.644 on his best run. This gave them second place on the day and top spot in the event overall.
2008 BMW 135i
Location: Santa Ana, CA
Best RWD track
Coming off last year’s freak engine fire, Berk was gunning for redemption at Streets of Willow. The company specializes in full exhaust system fabrication and high-flow cats. With focus recently shifting from imports to the BMW 1-Series, they’re becoming experts at dialing-in the car.
Just like last year, the BMW had limited engine modifications, restricted to a Berk exhaust system, downpipes, AEM meth/water injection and GIAC software.
Making only a few runs at the drag event and putting down respectable numbers at the dyno, the team’s goal was to perform well on the road course.
Owner Bryan Min spent time developing the KW Motorsport coilovers to the perceived track conditions a few weeks prior to etGP11. He also had Andrew Brillant from VFiber involved in the development of new aerodynamics for the BMW’s body kit.
Carl Rydquist, a European endurance racer and chassis engineer by trade, was then able to shave a few seconds with more fine-tuning the car. He piloted the BMW 135i to first place on the track with a 1:24.694 lap, and they were absolutely thrilled.
European Auto Source
2011 BMW M3
Location: Anaheim, CA
European auto source is a BMW tuning shop dedicated to supplying OEM plus modifications, particularly for the E92 chassis. To compete in our event, the shop entered its supercharged E92 M3 with an AP Racing big-brake kit and KW Variant 2 coilovers.
With this popular platform, EAS wanted to show how these modification would perform against purpose-built racecars.
Hot on the heels of an E46 M3 racecar in the drag racing, their E92 ran a time of 12.298sec at 120.75mph. Placing second among the other BMWs, while coming third in the RWD category.
The following day, the team was disappointed with the dyno results, which yielded only 457hp but it earned them valuable points with a fourth place result.
At Streets of Willow, EAS handed the keys to Jordan Yost: a friend of the shop as well as a driving instructor. He was able to record a lap time of 1:27.713, cementing fourth place overall. The team’s performance remained consistent throughout the three days, without any on-site tuning or trailer support.
Platte Forme AG
2001 BMW M3
Location: Alhambra, CA
As a new company, Platte Forme is a race preparation shop that looks after several local BMW track cars. Being their first time in etGP, they didn’t know what to expect. So Toan Nguyen’s brought his supercharged E46 M3 they’d been using to develop in-house performance parts for the past four years.
The team did better than expected at the drag strip, recording a 12.241sec run on the quarter-mile at 119.21mph, followed with 420whp on the dyno.
At the track, the team had little experience competing on the Continental ExtermeContact DW tires and were up against a host of professional drivers.
Friend Terry Liu was able to skip college to drive for the team. He quickly got down to business and logged as much practice time as possible before securing fourth place on the road course with a 1:25.887 lap time. “The tires surprised us,” said Toan. “We weren’t expecting them to perform so well. It’s actually a very good street tire.”
2008 BMW M3
Location: Mountain View, CA
We had a few first-timers this year, including Sonic Motorsports, which specializes in Audi, BMW, Mercedes and Porsche.
Darwin Tjiputra has been building his supercharged E92 M3 for the past five months, Dialing in the alignment, aero and corner-balancing the M3 before driving out with friends Calvin Wongkar and Alan Chaves to test the modifications in etGP11.
It was also the team’s first experience of drag racing and being on a road course. Having great fun, they traded seat-time in the drag racing to see who was the fastest. However, there was a problem with the new titanium bolts they’d been given to test before selling in their shop. All five snapped on the rear corner, sending the wheel rolling off on its own. Unable to replace the bolts, they settled for a 13.258sec pass.
The next day, they blasted to third place overall on the dyno, laying down 486hp. But they couldn’t keep the momentum going on the road course. The team noted that the car was understeering and the crew had limited tools to remedy the problem. Calvin and his friends had a blast and plan to bring a support crew next year!
2001 BMW z3 m Coupe
Location: El Monte, CA
From basic maintenance to performance upgrades, LTBMW provides a complete service for BMW owners. They entered etGP11 with Brandt “Mad Dog” Tarumoto’s M Coupe, which was undoubtedly one of the dark horses in the event.
“Its not what I can do, but what my car can do.” Brandt stated. So he asked his friend Gene Sigal, who’s raced in the Grand Am Rolex series, to pilot his BMW.
At California Speedway, Sigal had a problem with the transmission not shifting out of second gear at 8500rpm. Short shifting second, Sigal could only managed a 13.411sec quarter-mile.
The following day, the car recorded a respectable 421hp dyno pull.
Unfortunately, the dyno session ran longer then expected so the team didn’t have time to diagnose the transmission problem. However, they fitted a longer shifter for better leverage that seemed to work at Streets of Willow. So Sigal was able to finish in seventh place with a best time of 1:27.729.
Next year, the team plans to change wheel sizes to take advantage of the different tire sizes Continental offers.
Groma Race Fabrication
1975 BMW 2002
Location: Duarte, CA
Groma Fab specializes in BMWs from vintage to new, creating custom metal fabrication, installing rollcages, exhausts and selling performance parts.
The BMW 2002 they entered belonged to customer Paul Ivie. It had been transformed with a turbocharged M20 2.9L engine and Groma standalone 20/30 ECU upgrade plus front-mount intercooler. It also had a factory 2002 Turbo widebody. Ed Haroutonian from Groma asked if they could run the car in etGP and the owner thought it was a great idea!
At the drag event, they improved on each pass as driver Mono Agulian became more comfortable with their customer’s 2002. Settling for a best pass of 13.214sec, they were frustrated because felt that a 12sec time slip was possible.
Competing against the latest European machinery was tough, but on the dyno Groma had the third most power BMW with 433hp at the wheels.
The result on the dyno took more time than anticipated, resulting in limited time to set-up the suspension for the track day. Faced with cutting and welding the rear toe adjusters in the swapped E30 subframe, they had to do without. However, the team was happy with the results and enjoyed the experience.
