What kind of performance upgrades did Hennessey install on the 2011 Chevrolet Corvette to increase its horsepower to 700?
Hennessey’s HPE700 package adds a TVS2300 supercharger, high-flow heads, an HPE cam, long-tube headers, a retuned ECU, upgraded induction, larger injectors with a Boost-A-Pump, and a 160 °F thermostat—good for about 700 hp at the crank.
