What's a safe boost levels for a 2.9 whipple on 91 octane? I'm currently running a 3.5 pulley at 13.7lbs of boost. Looking at going with a 3.25 any idea what that pulley would put me at? Thanks

Each 1/8" is 2 lbs I believe. The info is on whipples website... But your not stock bottom end are you? Then it could be different.

9.7:1 compression, CNC LSA Heads, LTs, no cats, TPIS 102 and I believe 10%OD crank. Trying to figure out if I should go 3.375, 3.25 or just leave as is.

I guess a better way of asking is will a 3.25 blower pulley with a 10%OD crank be safe on the blower? Thanks

Max blower speed is 18,000. I'm sure whipple has a formula on their site. It also depends on how high your revving.

Exactly.

It's more about the maximum blower speed in this application.
