what fuel are you running with just the blower?

i would think with exhaust and decent gas and the whipple at 7psi you could bump into the 12's

i ran a best of 12.7 at 9psi on an lq4. that was with 100octane, it would have gone faster becasue i wasn't at the limit of that gas. it could have handled more boost or more timing.

 

93 octane.i have no programmer now. iused to have a whipple which is made by street and performance SUCKS that is why i asked for help.i also have electric fans,flowmaster muffler.what about cutouts
