IF YOU DO A 2.9 UPPER PULLEY AND 4LB LOWER IT WILL BE GOOD SET UP WITH A GOOD AMOUN TOF BOOST... . I HEARD WITH A 2.8 YOU GET BELT SLIPPAGE.

2.8 is cool. Anything lower there's potential for belt slippage. I have a 2.8 with a 2lb lower making 5xxrwhp + on 12psi. Would I make more if I go with a 4lb lower? Oh and I have a belt tension.
