Whipple and Kb people?

[lachj1]

For those of you running the whipple and KB superchargers that are running 17-18 lbs of boost. Are you adding fuel to the gas? Running lower timing to use pump gas? What's the cut off point on pump gas with what timing?

I want to upgrade but I just want a little info.
Thanks

you can run 17 # safely on 93 octane as long as you dont go nuts with the timing. I would just let your tune determine exactly how much timing you should have :beer:

My tune has timing <20 degrees, around 18ish19ish at WOT, 91 Octane, a/f set for 11.5-12.0 at WOt.

I was told 17# on pump gas is about max. 17# would be the 3.0 pulley for me. Currently i'm using the 3.2 RR non slip, seeing right around 15#
