  • Street legal 6 second Corvette?!

    Not that you'd really want to drive it on the street, but in theory you could.

    If you follow HOT ROD Drag Week, you have heard of former champion Dave Schroeder and his cousin, John Ens, who have been racing on Drag Week since 2010. The first car was a red and white 1955 Chevy that ran 8.90s at more than 150 mph in the Modified Power Adder class. In 2012, Schroeder debuted a 1966 Chevy Corvette with a nitrous-assisted 872-inch Reher Morrison engine. Schroeder and Ens took some losses, DNFs, and even a crash before winning the Unlimited class in 2017. The next year, Tom Bailey appeared with his Camaros and put them on the trailer in 2018 and 2019 while running the first 5-second pass in HOT ROD Drag Week history.

    Starting early in 2021, Schroeder began to put together a chassis to handle all the power to compete. "Originally we were looking for a C1," says Schroeder. "But the aero was bad." The C7 has a slicker shape and can hold a 36.0x17.0-16-inch Hoosier slick. The Pro Mod chassis is from Jerry Bickel with a 25.1 certification that allows the car to run at the top of any Drag Week class. The body is from Cynergy painted in the original Corvette Gran Sport livery from the 66. There is nothing off-the-shelf about the shell. The hood needed to be removable to service the car, the nose needed OE headlamps to see during the nighttime drives, and the car needed taillights and mirrors to be legal for the race. The Pro Mod wing was carefully trimmed to fit the body and the car is overall 1-foot narrower than a C7 Corvette Z06.

    How Is This Pro Mod Corvette Street-Legal?


    There are some additional tricks to get the car down the highway. There is a small fuel tank that attaches to a custom hitch behind the differential. For the drives, the car can run on premium pump gas when switched from the main tank in the front to the auxiliary tank in the rear. On the track, the car runs on methanol. The front brakes use carbon-fiber disks to handle the heat from the road and are a combination of an Anglia spindle with 5-lug hubs from a Chevy G-body. The radiator has its own water pump welded to the tank and is used for both the street and track. The oil pump bolts to a billet oil pan for strength on bumpy roads and long drives.

    The engine has four kits of Monte Smith nitrous oxide that can deliver 1,000 hp on top of the estimated 1,750 hp the engine makes naturally aspirated. To get this kind of power, they started with a Dart block with 5.3-inch bore centers and added a set of big Dart heads. To get it all to live on the street, Ed Iskendarian pitched in with a cam grind that didn't beat the valvetrain to death. After that, it's all about fuel and temperature management. The transmission is a Rossler TH400 with a Neil Chance converter and a Gear Vendors under/overdrive in front of a 10-inch fabricated differential with a 4.56:1 gear. Nothing too exotic. To keep it cool, they used a giga-trick Laminova cooler that doubles as an engine oil cooler and filter.

    Another trick that no one seemed to notice is that the intake manifold is mounted backward. "Warren Johnson answers the phone when I call," said Ens. "I started to ask him about where to pick up the air and he finished my sentence for me." The intake was reversed, and the hood was raised to take advantage of the high-pressure area around the cowl. Much like a 1970 Chevelle, the Corvette uses cool intake air from the base of the windshield instead of picking hot air off the ground like a modern Pro Stock car.

    As this is written, Dave Schroeder and John Ens are leading the Unlimited class at Drag Week 2021. Their quickest e.t. is 6.52 and their fastest mph is 210.

    Thanks meyerweb. That is one fun ride. I can’t imagine what it would be like to be in it going down the track at full tilt. Probably super scary just going to the corner ice cream store. Fun to read about for sure.

        HMM? Just No! Straight line only real roads have curves. It would in the ditch trying to keep up with any stock Corvette. It belongs at one place at the quarter mile track.

          I doubt there's any intention to drive it on the street. Just that the rules for that class require it to be street legal (with different tires, obviously).
