Let me clarify. I was refering to the Corvette example.

In the GT3 class, a supercharger can be used if it is available on the street car that was homoligated.

That is the case with the B6. The 7.0 NA Z06 was the car that Chevy Homoligated so it cannot.

If they chose to homiligate the ZR1, im unsure how it would be regulated as it is such a large engine. The GT3 technical regulations are not clear about how supercharging is regulated. I know the Ford GT in the series is a Supercharged 5.0L and the Jaguar XKR uses a 4.2L supercharger but the ZR1 is 6.2L and makes over 600hp. The good power zone in GT3 is between 500-550hp. The LS7 makes that from the factory while an LS9 would need extreme air restrictors to get to that number. It would be better if the just stuck with 7.0L
