Re:my dyno numbers at 3 psi, lol

Small world, I'm in Mentor.
Black first gen neon coupe w/ a red hood.

I didn't know you were turbocharged now but I've seen you around here and there.

Going to go up to Thompson anytime soon?
I should be back there when I can pass NHRA tech, still need to replace the windshield and tie down my battery...

Re:my dyno numbers at 3 psi, lol

dont you guys have boost levels on your dyno charts? i know mine do. ???

Re:my dyno numbers at 3 psi, lol

Those are really nice #'s man, whats ur car weigh again?

Re:my dyno numbers at 3 psi, lol

stock weight is like 2858 or something like that :-\ and with my subs (fiberglassed in), full interior, etc etc, (god only knows the weight now :-\) i ran a 14.9 @ 92 or 93 (gotta look) at 4psi lastnight at thompson with a good amount of wheel spin and hop and just a touch of bogging. that track blows though, so im gunna try to get out to norwalk soon (most guys say they run .2 less at norwalk vs. thompson) so we'll see what happenes with all that. im just waiting for some injectors then i should be able to turn up to boost some more.

yes its ok.

also you guys gotta remember its not PSI that makes power it's CFM and that turbo (t3/t04e) will push alot of air. The 2.4 is a big motor and would consume that much volume of air. I'd say those are around where it should be.

Air volume has nothing to do with it, it's air mass that makes power! Air volume varies by temperature, so flow 500CFM at 100°C and that's not nearly as much air as 500CFM at 20°C. CFM is invalid when talking about turbochargers, hence all compressor maps have lb/min or kg/min and never CFM.

UHmmm...it's a T3/T4E so I don't think the air temperature would be 100 degree celcius.
Power seems kinda high for a 3 psi setup, but then again...it's a 2.4 liter engine and a pretty big compressor, so it would be flowing a lot of air and the engine would be using the air more efficient than a smaller displacement engines.
