ISBN 1-57427-057-5 Unique Characteristics: Unique Characteristics: The GTP cars were raced with three body styles… long tail, medium tail and short tail. This chassis has always appeared as a long tail; see other chassis’ for examples of mid and short tail. Modifications: Notes/Race History: In 1985 and 1986 this car scored 4 poles positions in 8 races, and finished first at Road Atlanta in 1986, setting a track record lap as well. The overall performance of the GTP series was hindered by GM’s continued practice of mixing actual racing with the perennial introduction of new technologies. From the GM perspective, the raison d’être for the GTP program was to serve as a rolling test bed for a number of new GM-developed technologies, including active handling and the OBDS II electronic engine management system, V6 engines, turbocharging, active suspension, and even throttle by wire. Nonetheless, wearing the Corvette name badge, the Corvette GTP more than once lived up to the history and heritage of its name on the track, posting a fair share of #1 qualifying and podium finishes. And, with the exception of the V6 in a Corvette, all of those emerging technologies of the 1980’s are alive and well in today’s Corvettes. Sidebar on the V6 development: Early in the program, the V6 turbocharged engine was adapted from the Chevrolet V6 229 CI cast iron block. Displacement was reduced to 209 cubic inches. The block was a Chevrolet over the counter item. The 1985 and 1986 blocks varied slightly; the 1986 block was redesigned for a one-piece rear seal. Internals and cast aluminum heads were over-the-counter Chevrolet off-road production items. A Warner-Ishi Model RX9-L turbocharger raised maximum horsepower to 775 HP at 20 pounds of boost. Famed engine builder Ryan Falconer ultimately squeezed 900 HP then a purported 1100-plus HP out of the little V6’s for Hendrick Motorsports.
