If the 8.6 would truly provide a 2lb increase that would satisfy me for now...(maybe).
Its a daily driver and use 93, just didnt want to go to much further than that and risk knocking and too much additional heat. Of course it'll be tuned too.
May upgrade the heat exchangers too.

I don't see how a 7.5% increase will add 2 psi of boost. The supercharger only produces about 9.4 psi in stock form. A 7.5% increase is only 0.7 psi. I could be wrong in how that is calculated, but I'd be surprised if it's actually 2 psi with a 7.5% OD pulley.
If it's only 0.7 psi, it won't add that much heat (about 14-15 deg F over stock compressed temperature).
