2011 Chevy Corvette Z06-RF has been realized by Vortech and includes a centrifugal supercharger, an air aluminium intercooler, a bypass valve, alluminium installation supports, a high capacity gasoline pump and increased injectors. However there are several differences between the two cars: the engine�s capacity, the exhaust system and the final performances.
In fact the ZR1 has been developed on the base of the LS9 6.2 litre engine, but the 7.0 litre LS7 that equips the Corvette Z06 permitted Romeo Ferraris to take advantage of the higher cubic capacity. First of all the higher reliability and, thanks to a high performance exhaust system realized by the Factory and a careful optimization of the electronics, to obtain more horse power at lower number of rpm (677 bhp at 6000 rpm vs 646 bhp at 6500 rpm of the ZR1) with more disposable torque all speed long: up to 823 Nm at 4950 rpm (The ZR1 reaches the maximum peak of 819 Nm at 3900 rpm).
