Termi is more than just a supercharger they have hand built engines with forged internals that can hold alot of power with out having to do anything bolt a bigger supercharger on and e85 be ready to terminate love the sonic blue nice ride.
I don’t own a C6 ZR1 but I have worked on a modified one at my shop. I have never heard the supercharger whine on it. All I heard was all the screaming bald eagles from the exhaust. 😂
It's definitely audible in the beginning before the active exhaust valves opened up and the wind undercut the sound. The Go Pro camera was literally on top of it on the carbon fiber hood. The camera picked up the sound nicely. By design, the twin roots rotor style superchargers are not as loud as twin screw or scroll type blowers.
