Yeah they read about 10% high. I register 492 @ 28psi, so figure 450-460ish.

i think i would put down more but i had my 2 stock wheels with drag radials in the trunk and 2 buddies in my car, about 200+ each.

Not really, but you know what? I think I may have a lifted head. The problem I have been having with this mis under sligt throttle could easily be mistaken for a bent valve. Fels the same way, which is why I am now leaning towards a lifted head. Occassional white smoke, etc. and even before the twins I was over 22 psi, so it is a possibility. Might have to have the head taken off and decked to ensure a good seal. These cars have horrible tolerances on the head.

Yeah, I read bout that a while ago too. I have an 04. I am pretty sure it int a bent valve, compression test was 159 160 160 160 when I checked.

i did a pull with a friends scan gauge i only had my 3in exhaust on and it said 266hp. so doing a 10% correction im at 240.. on 13psi

moreause · 11-04-2007, 10:57 AM

the highest i have seen is 430 at 22 psi
but my map is clamped at 18 psi so the value it is supposed to show is probably higher

srt4geezer · 12-19-2007, 01:03 AM

I did a pull today & I really wonder how close it really is. I got up to 423 at 20psi. If I do go to the dyno on Friday we will see how close this is.

Goodluck

10% sounds like it s/b correct if it's at the crank... I have a "stock" S2 with MOPAR cat-back... I've hit 333 hp during a third gear pull. 10% of that is 303 hp, and take 15% of that for the FWD WHP percentage.. so that's 255.85 at the wheels.. which is somewhat around the MOPAR S2 rating of 265.. also my fuel mileage on the gauge is about 10% low. Gotta set the adjustment to 90 on the guage one I get it reflashed.
