Hi everyone. I have a 2006 ctsv with a paxton novi 1500 oil fed h/u. 60# injectors and KB BAP. Stock motor (ls2). Does about 615~ but hitting bad belt slip up top. I will be going 8 rib, and want just another 20-40 without slippage.

Which combo gets your vote? 1 or 2? What would be the power difference on these setups, and is the most aggressive setup going to be too far past peak efficiency? Or will it be too hot? Detailed discussion appreciated.

Current setup:

3.33 pulley
7.48 in balancer (stock diam)
6 rib system
54,3xx impeller speed
92.125 belt

Setup 1
3.45 pulley
8.23 balancer (10%OD powerbond)
8 rib system
57,5xx impeller speed
belt size??

Setup 2
3.33 pulley
8.23 balancer (10%OD powerbond)
8 rib system
59,7xx impeller speed
belt size??
