S5 6 port turbo

With the high compression ratio rotors you will have better off boost throttle response and you will make more power per pound of boost. You will also generate more heat and will run into a point where it will become better to have lower compression rotors and run an extra pound or two of boost. This point will more than likely not become apparent until higher boost levels (15psi+ on straight pump gas).

I personally would use S4 turbo 8.5cr rotors, but I would probably be building a different car.
