I'm running a 3.0 upper/stock lower and see 15 psi with headers. No dyno numbers with the headers yet. I want more PSI, so I was thinking of 2.75 pulley. Anyone running one with stock lower?
I can get race gas leaded 110 for $4.75g. I would run that all the time if I could get tuned for it. I just don't know if thats possible.I have a 3.0 upper and 2lb lower with mid lengths I see 17lbs. Might throw a 2.75 on for shits and giggles with some race gas to see what she puts out.
3.5 upper 4lb lower for pump gas (93) tune. 3.25 with the 4lb lower and race tune nets me the BIG numbers. 17-18 lbs street. 18-20 lbs race.
3.25 and stock lower. i'am seeing 20 psi. o wait i got a KB 2.63.25 upper and stock lower. I see 17lbs right at the top.
And probably still makes the same power than the 2.3 You live around Baton Rouge? Saw your 1/4 times! Congrats!3.25 and stock lower. i'am seeing 20 psi. o wait i got a KB 2.6
o dont know about that, i got mustng dyno #s btw.And probably still makes the same power than the 2.3 You live around Baton Rouge? Saw your 1/4 times! Congrats!
What kind of numbers does your street tune make? Just curious because I'm running the same setup and i have a 3.2" RR pulley sitting in my garage. Trap speeds on street tune?
I run a 3.25 with a stock lower and am seeing 15#'s.
