You are never gong to hear the S/C noise over the exhaust with the bypasses open and the engine being run as hard as the driver (probably Jim Mero) is driving the car.
Plus, I think it's unlikely the 4G ZR-1's engine could make 750-hp and pass emissions without being supercharged or turbocharged.
Astute observation! I concur....wish it was N/A, but it will be forced induction per Hib's comments above.
