what the pulleys combo for whipple 2.3L to get 18 psi ?
Is it safe to run 18psi on 93oct pump gas ?
i have 4#,6# lower Rings ,big TB , TF heads,built engine ,and full catback
whipple told me lower 4# with 3.125 is 18psi that correct ?
#2652 2001 ,WHIppLe 3.4L,TF heads ,OBX Lt`s,magnaflow exhaust, Drop sheckles 2 inch , HiD 6000k Heads light & Fog`s,Black tail light,AFCO HE+Fan,TF Ic tank , 160* stat STATE OF KUWAIT
my motor only has 300 miles on new build but im running 8lb lower and 3.375 upper and i havent held truck to see how much boost it makes but if you just slap the loud pedal it jumps to 15lbs instantly. there are other variables that come into effect also
What other mods you running:
It's all in my sig. 12* of timing. 93 octane
But now that I think of it, it was at 16lbs before I had to gut the cats, so it should be lower now. Anyone know about how much lbs of boost you loose after goin catless?
