It would break up some up top. I have never driven it on 91 with the 75mm (14.5 psi) pulley. I definitely wouldn't feel comfortable driving aggressively like that on 91, so a turbo would definitely be better because I wouldn't have to change my driving like I mentioned.
Also, when not on E85 with advanced timing and high boost, pulling timing with high boost might result in the same power or knock resistance as advanced timing on low boost, but the lower boost level will have better EGTs, less heat and less cylinder pressure for the same horsepower. It will have better fuel economy too, so while it may be done on a supercharger, the turbo would be better with flex fuel.

Except I'm finishing up a flex fuel supercharger with a total cost of around $500, try that with a turbo...lol

BTW, the $500 includes the $156 it cost me to add flex fuel already.
