4,400HP In One Day - Checking Out The Drift Office Supra Dyno Shootout

PNW modded MkV take on the Dynojet

How much power does an A90 Toyota Supra lay down? Finding out was the driving force behind The DynoStation @ Drift Office Supra Dyno Shootout. Co-sponsored with online-based car club Supra Sessions, the event was quickly planned just after Washington began is phased post-COVID-19 opening but still drew 16 MkV Supras throughout the day.

The new Supra has been in the center of the rumor storm for more than a decade. As the car moved closer to reality and the swoopy coupe's platform partner was revealed, a new level of hype was born. Would anyone buy one? How would they perform? More importantly, would the Toyota/BMW mash-up be embraced by the JDM tuning community? The biggest point of contention is the BMW B58 engine. It has a built-in following of tuners on the Bavarian side from its development in the 3 Series, so the JDM shops would be playing catch up.

The DynoStation Supra Dyno Shootout was a great way to take the early pulse of the 2020 A90 Supra and its potential as a tuning platform. The A90 features a twin-turbo 3.0-liter inline-6 that's factory rated at 335 horsepower. The DynoStation has tested a number of stock Supras and they average around 336 whp on the company's Dynojet chassis dyno—hinting that the factory rating of 335 is a actually touch conservative.

The following cars were the day's top performers among the 11 Supras that challenged the rollers. We'll share a little backstory, denote the engine's tuning strategy, and list the installed performance parts of each car.

Zach Peters - 470.81 whp

The champion of the day, Zach's Absolute Zero White Supra was the only car running an ethanol blend, calculated to be E38. An MHD Flasher Module runs the show. With a Wi-Fi adapter, the Module can load an initial map in about three and a half minutes, then drop updates in about 20 seconds, all wirelessly via a compatible cell phone. The setup can monitor and display parameters such as oil temp, boost pressure, actual load, or individual cylinder ignition timing, and also datalog using standard CSV files. Zach says he's got an E30-OTS Stage 2 tune, which is the top of the line offering from MHD. Like many of the Supras at the event, Zach's mods addressed breathing.

Tyler Stanford - 443.73 whp

Tyler has no problem standing out in a parking lot full of Supras. With a fat-fendered Pandem V1.5 wide-body kit, 19x12-in. wheels, and a huffing and puffing air suspension, there was a lot of buzz surrounding his Supra. The Toyota met its high expectations by placing second on the power charts. The backstory of Tyler's Toyota breaks what many believe to be urban legend—a 'win this car' sweepstakes.

"I won the vehicle and $30,000 cash back in April in a sweepstakes. The contest was run by a company known as 80Eighty from Salt Lake City, Utah. I bought some clothing and accessories, and out of the millions of entries, I somehow won! I wasn't sure it was legit... but the car's sitting right there. Meet Dream Car Giveaway no. 32."

RK-Tunes handles fuel and spark with a Stage 2 low boost/stock boost map. The tune is designed for 92 octane pump gas with no accommodations for ethanol. Although Tyler won the car on luck, he has taken a logical approach to his ownership and researched what is going on with the Toyota. "RK-Tunes is a company based out of New York," says Tyler. "The owner, I believe his name is Jordan, is very well known for working on Porsches and BMWs, and now he's really submerged in B58 modifications for the A90 Supra. He is quite the magician... his YouTube and social media is awesome, very thorough, and he likes to explain what he is actually tweaking and why."

  • RK-Tunes 92 Octane
  • Pure Turbos Stage 1 Turbos
  • Frequency Intelligent (FI) Exhaust Cat-less Downpipe
  • Frequency Intelligent (FI) Full Race Exhaust W/Carbon Tips
  • Euromotive Charge-pipe
  • Euromotive Intake
  • Cusco Power Brace
  • Mileage: 3,100

Jeff Sitthi - 415.39 whp

Jeff's Supra sports a classic black body, bronze wheel look, and at 415 whp, the car's beauty is more than skin deep. Jeff is running a bootmod3 (BM3) OTS Stage 2, 91-octane tune from Pro Tuning Freaks. This system is cloud based, so the tunes are not emailed as CVS files or map files. Programming can be executed by a laptop computer running Windows or MacOS or via mobile on an iPhone iOS or Android device. Jeff's short mod list illustrates you don't need a lot of hardware to coax big numbers out of this Toyota.

  • bootmod3 (BM3) OTS Stage 2 91 Octane
  • Active Autowerke Catted Downpipe
  • Remus Racing Axle-Back Exhaust
  • Mileage: 9,100

Richard Chen - 415.67 whp

Richard is a long-time Drift Office customer who made the jump from a Subaru BRZ to the Supra. He loves the 'big dog' and his B58 is tuned with Bootmod3 (BM3) on a cat-less 92-octane off the shelf tune. This car also illustrates good gains can be had with basic bolt-ons, but like most of the participants, Richard is looking for more hardcore parts to hit the scene. "I'm very happy with the current tune but it will definitely need to be tweaked once more parts come into play." The hard part is to know what the next wave of parts will be and when they will drop.

  • bootmod3 (BM3) OTS 92 Octane
  • ETS Cat-less Turbo Back Exhaust
  • Muffler Delete
  • Mileage: 5,000

All tallied up, a whopping 4,445 whp was generated on the day. That's an average of 404.09 whp per A90, not too shabby for a combo that puts down around 336 whp in stock trim. It was good to see the dyno light up, and the whole day reflected well on the Supra as a tuning platform. It will be interesting to see what happens when these owner's courage, and their boost, gets turned up when turbo upgrades hit the scene!
