Corvette with Active Downforce Generator (A little off topic)


I know this is a little off topic, but knowing that lots of motorcyclists are gearheads in general, I thought that this car might be interesting. When I first saw this car in Grassroots Motorsports magazine, I thought it was very cool. The performance to price-of-build ratio is astounding. So what’s so special about this car? I cut and paste the features list from the eBay listing…

Here’s a quick summary of some of the car’s features:

* 1986 Corvette Hatchback – heavily modified for race purposes; inspected with new rebuilt salvage title issued, and current Ohio registration.
* Engine – 350 TPI modified with twin turbos (Garrett GT25’s), dyno’d at 295 HP, 440 ft-lbs Torque at wheels (vs. stock 187 HP; 275 T) at 6 psi boost. Custom engine tune. Engine recently rebuilt.
* Transmission – THM 700-R4 4-speed overdrive automatic; recently totally rebuilt with manual valve body
* Wheels/Tires/Suspension – brand new 295/40ZR17 Kumho Ecsta V710 competition tires on 17×9.5 cast aluminum 1990 OEM Corvette wheels, Koni 8040 shocks; rear mounts modified to adjust car height; 1/2″ wheel spacers with longer studs for wider track, setup and aligned to balance corner weights.
* Active Downforce System – M1 Abrams Tank cooling blower powered by 45 HP Polaris engine evacuating 10,000 cfm of air underneath car generating 1000 lbs of downforce, substantially increasing tire grip and resulting in a 1.3 g skidpad capability.
* Safety Items – ABS brakes; B-pillar replaced with 5-point roll bar (formed and welded 1.5″ tubing); rear mounted electric cut-off switch; new Simpson 4-point safety harness; rear mounted battery; cockpit fire extinguisher.
* Custom 5 gal. stainless steel fuel tank

Notice what I bolded? This car (named the Cheaparral by the build team) is an awesome knock-off of the original Chaparral race car concept. Any “street-legal” car that can pull 1.3g on the skidpad is pretty cool in my book. It’s also got some cool celebrity bling with signatures from both Jay Leno and Jim Hall.

So now back to cafe racers… 🙂
