1990 Callaway Corvette Super Speedster
This Super Speedster is one of only three cars equipped with the turbocharged LT5, the same engine which powered the Callaway Sledgehammer Corvette to 254.76 mph.
Also known as the Series II, only two Speedsters came equipped with the turbocharged LT5, and this is the only one wearing the Paul Deutschman-designed AeroBody.
To accommodate the intercoolers, Callaway’s AeroBody was slightly modified with twin intakes which replaced the four seen on the earlier Speedsters. The bodies retained their wrap-around, low profile windows and sleek look which was unburdened by aerodynamic devices.
Unlike the earlier Series 1 speedsters, the Super Speedster is based on the Corvette ZR1 and a 750 bhp twin turbo LT5. This uses new engine management, fuel injection, exhaust, headers and catalytic converters to achieve over 750 bhp.
This Super Speedster was painted in Cherry Smash with My Favorite Blue leather interior. At the time of writing is completely original with only 13,174 on the odometer.
