no, they were clipping at anything higher than 3 because the fmu would push the fuel pressure up to 80+ then and which point they would clip.. it wasnt the turbo making the clip..thats not related, it was the relly high fuel pressure doing it from the fmu. i agree though, the numbers do seem pretty damn high for 3 lbs...but hey, whatever, im not complaining, lol

Re:my dyno numbers at 3 psi, lol
 

is that a safe a/f ratio?

Re:my dyno numbers at 3 psi, lol
 

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.

The HO intake manifold, throttle body, and pullies would make quite a big difference, did you swap in the HO cams too? On JBO a while ago there was a post about a guy making 20whp with those cams. He dynoed before and after to see what the difference was.

Re:my dyno numbers at 3 psi, lol
 

nope, the cams arent in. im still not sure if ill do them or not. a lot of guys said they didnt gain anything and most lost a good amount of torque. also, the pulley isnt on either...its just sitting in my garage. alls i have on it that are HO are the injectors (getting replaced with much larger ones today or tomarrow) , the mani and throttle. i think my port job wasnt perfect on the mani to head because it seemed to make me about a thenth slower at the track after i did it. and keep in mind, im auto, so im pretty much always consistant. the only diff i noticed form the mani and t/b was my top end started to scream. engine totally changed pitches at 5.5k and up since then. but track times were a tenth slower...

ohh yeah, and for the a/f ratio. under boost it was bout a 13 in that run. most others i got it tweeked to bout a 12.6-12.9ish area most of the time. when it wasnt in boost at all and was being driven normal, the af on there shows like a 15 i think. id have to go back at look through the tables, but i believe thats areound a 15. stoich on a n/a motor is 14.7, so that seems bout right to me since it wasnt in boost and preatty much running off factory settings.

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.

Re:my dyno numbers at 3 psi, lol
 

the boost gauge works! lol, ive tried other ones and they all read the exact same thing. remember, it is a larger engine and turbo than most of you are used to, so itsgunna make a lil more power. ::)

Re:my dyno numbers at 3 psi, lol
 

Dam, thats a flat A/F for a rising rate. It looks to be in the 13's, which I bet is fine for a lower C/R engine. What is the C/R anyways?

Re:my dyno numbers at 3 psi, lol
 

Compression is around 9.5:1.

Ive seen some crazy numbers from these motors, and i believe his. His arent that far fetched. If you do it right, the LD9 responds very well to boost. Most people only running 5-6 psi maximum are happy.
