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?
Everyone with a whipple... Pulley sizes post em up.

3.50" stock lower, Hilton gauge overlay not yet installed, boost= 13????:shrug:
The power is too much for the tires now, more boost would be NUTZ.
Too much power doing open track = too much heat, 20 minutes is a long time to be hammering.

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.
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.
3.25 upper and stock lower. I see 17lbs right at the top.
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. 19-20 lbs race.

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?

3.20 RR upper and 4lb lower gets me 19-20lbs of boost. 93 Octane tune only.
And probably still makes the same power than the 2.3
You live around Baton Rouge? Saw your 1/4 times! Congrats!

o dont know about that, i got mustng dyno #s btw.And probably still makes the same power than the 2.3
I will trap at 126-7 with the street tune. Race tune put me at 129-30. I have not been able to get better than an 11.6 with it because of piss-poor 60' times. Havent been yet this year but slicks with skinnies up front are in the garage. :coolman:
3.5 upper/6lb lower here with bassani mid-lengths nets me around 18-19lbs, depending on outside temps...
3.25 upper with longtubes and I have seen 19psi, but usually around 15-17psi
I run a 3.25 with a stock lower and am seeing 15#'s.
Hey you might get some 103 unleaded.That leaded gas will coat your sensors and they will be junk from what i heard.
Me too.
I think it would be important to include what GEN Whipple people are running.
2300, W140ax, Gen2 W140ax.
Gen 1 W140ax
3.0 upper, stock lower. 17 psi.
