East Coast Supercharging 1999 Corvette Convertible - Black Magic

East Coast Supercharging's '99 convertible holds the quarter-mile record for blown Vettes and this is no race car!

"Every year, there is a so-called 'nationals,' which all the Corvette Challenge guys go to. There is what's called the Pro 8, which is a heads-up race of the eight fastest Vettes there. That's what we're going for. The problem is that now, what are essentially race cars and dragsters are allowed into the class. These suckers can run in the 7s, whereas we're running a true street car. But it's no big deal because it's not like we're racing for any crazy amount of money. Everyone knows what's a street car and what's not. So if we have the fastest street car of the day there, that's really all that matters to us. We very often are able to do that."

Though there are a few changes to the current setup coming before long-most notably a swap to a trans-brake-equipped TH-400 transmission for increased tranny longevity-streetability will not be altered. To that end, Doug will swap to 3.15 gears to keep the revs down on the highway. "Not losing streetability is big-time important to me. I take this car on all the Toys for Tots runs, I go on a lot of the Vette cruises, and I take it up to my ski house in upstate New York. It really sees a lot of road use on top of the track use. That's the most important thing I try to let people know: Yeah, I'm running some nice numbers, but this Corvette is still completely driveable. [It has] air conditioning, stereo, the whole nine yards. Making a race car fast is not anywhere near as hard as making a street car fast! But we've done it-and we can do it for anyone."


Keeping tabs on boost from inside the cockpit, Doug sees a maximum of 20 psi from the Paxton supercharger. Though this is a decent amount of pressurization, the car runs nothing but 94-octane unleaded fuel at all times-a feat made possible by the ECS water/methanol injection system on board.

At close to 150 mph, extra safety is a must. A full rollcage, Sparco seats, and RJS harnesses help fill that role. Note that the factory stereo, climate controls, and other luxury goodies are all still in place.

Also located in the cockpit is a wideband A/F ratio display to ensure everything is burning nicely in the cylinders.
