The World's Fastest Acura, And A Pretty Quick CRX
Hondata co-owner Doug MacMillan and wife Miriam set a total of five land speed records at last August's Bonneville salt flats' Speed Week in Utah. It began with a G/BGCC class record of 221.652 mph in the company's 2.0-liter RSX running twin Rotrex superchargers, installed by KraftWerks. Doug also went on to take the G/BGALT record at 208.646 mph. But the highlight was the G/BFCC record, originally set at an impressive 226 mph in 1990 that Doug bettered at 234 mph thanks to the 600hp, supercharged K20A. The record wasn't easy though. The RSX went into a spin after the fifth mile during qualifying, flat-spotting the tires. The team only had two spares so they swapped the 25-inch tires out back to the front and put the spare 26-inch tires on the rear. Of course, all of this changed the RSX's gearing, which meant the RSX needed more power. Although the engine had yet to be tuned with nitrous, the tanks were turned on and the RSX was dialed in with the additional 100 hp. And that's how you become the world's fastest Acura.

Doug's wife Miriam also campaigned the company's Kinsler-equipped CRX that broke Doug's previous G/GCC record on the three-mile short course and also broke the 167.988 Gas Competition Coupe record with 178.584 mph. Qualifying runs on the long course resulted in speeds up to 189 mph. According to Doug, with a little aero work and a few engine tweaks, 200 mph is in the CRX's future.

Know Your Bolts
Whether you're working on an '88 CRX or an '05 NSX, chances are you'll be sharing a lot of the same hardware. Honda's one of those companies with the foresight to use many of the same nuts, bolts, studs, and other fasteners across its lineup of cars. The results cut costs and can save you from reaching into a separate toolbox for each car. Although individual lengths can vary, there are a few Honda-specific thread pitches you'll no doubt find on just about every Honda ever made and that you should know about. As you'd expect, there are many other oddball and chassis-specific nuts, bolts, and studs out there, but here are the top four you'll likely come across.

6x1.0mm Often referred to as the "10mm" because of the size wrench or socket required, Honda uses these small nuts, bolts, and studs for fastening oil pans, water pumps, ground straps, cylinder head covers, and just about every small-size bracket or clamp you can think of.

8x1.25mm Honda uses this hardware for fastening intake and exhaust manifolds, oil pumps, brake calipers, and more. These are also mistakenly referred to as "12mm" hardware due to the wrench size used.

10x1.25mm These larger bolts can be found anywhere from downpipe assemblies to shock and strut hardware, and from starters to hub assemblies. Officially, these are 10mm bolts but are often referred to as 14mm ones.

12x1.25mm These bolts are generally used to fasten transmission and block assemblies together as well as suspension pieces like lower control arms and engine mounts. You'll need a 17mm wrench to get at them.

Element Owners Meet
Who doesn't love Honda's versatile rolling toaster, better known as the Element? There's no doubt that a group of SoCal locals who call www.elementownersclub.com (EOC) home are diehard fans of the spacious people mover, and last August, despite the sweltering heat, swarmed upon nearby Super Autobacs' parking lot for a routine Element meet and greet. With more than 40 participants showing up to share war stories, swap customizing ideas, and put some names to some faces, the EOC's SoCal chapter put together a successful show and shine with plans for another in the works. Wanna join in? Log on to www.elementownersclub.com for updates.

Acura's Most Powerful Engine ........Yet
305 horsepower can be yours now, and you don't even have to wait for the fabled NSX replacement, that is if you're interested in the all-new Acura TL. That's right, it's the '09 TL that benefits from Honda's highest output production engine to date. It might look like the RL's longblock assembly at first, because it essentially is, but it's better than the RL's. There are actually two V-6 powerplants that are offered for the TL, but you'll need to upgrade to SH-AWD status to get the 305hp, 273 lb-ft of torque version that you want. The SH-AWD boasts a massive 3.7-liter V-6 that features VTEC on all of its SOHC-operated 24 valves, an 11.2:1 compression ratio, a true cold-air intake system, and a massive 69mm throttle body and exhaust when compared to its predecessor. It even weighs less than the old V-6 thanks to its high-silicon aluminum cylinder liners, which also play a part in the engine's larger bore size. Of course, the 3.7-liter features a forged crank but it also benefits from forged steel rods and aluminum pistons that are continually cooled by an oil mist. The 305hp V-6 also features more aggressive camshaft lift and duration specs when compared to Acura's other V-6 engines, like those from the MDX. In fact, there's 4-percent more lift on the intake valves and 10-percent more on the exhaust ones. Valve overlap and timing has also been optimized specifically for the 3.7-liter TL engine and its cylinder head ports have been tuned accordingly. The VTEC transition begins at 4,700 rpm and peak power happens at a conservative 6,200 rpm. Despite all of this though, the 3.7-liter still meets all of the latest EPA and CARB standards and has a lofty 100,000-mile tune-up interval.
