Very Dissapointed ......
So I finally get the emanage in and the car feels great, a/f is great went to the dyno to get the car dynoed. Now previously on 7.2 lbs i made 360whp and 349ft/trq. Yesterday I dynoed my car on 12PSI ON STOCK ECU!!!!!!!!! It was an accident and I upped the ebc too much, thank god nothing blew. But anyways at 12lbs i only made 350whp, thats 10 whp less then i made on 7.2 lbs!!!!!!! I need to check my compression tomorrow and see whats up with that, and if its not the engine, then its gotta be the turbo, since it is blowing out oil from the comp side. Also, i noticed that after the first pull on the dyno I looked at the turbine wheel and it wasnt moving in nuetral, usually it moves a little because theres still some exhaust gasses going out. Im stumped for now, gotta figure out what is going on, this sucks ***.

no this was on stock timing thats why i said im surprised i didnt blow my engine lol, but the numbers arent what they are supposed to be, on 12lbs i shoulda hit over 400 and if not be very very close to it.

Anyway, I looked around at home for the compression tester and I dont have it.

Did you dyno at the same location? every dyno shop has different settings, such as elevation, the higher the elevation the higher the hp, etc.... also at 7.5psi 360whp? that dosnt sound right. Or maybe your turbo is not efficient at 12psi and better at lower boost? *shrug*

From the sound of it, your turbo maybe the problem. The turbine should spin freely even with a little bit of exhaust pressure, oil being blown out of the compressor side doesn't sound too good at all. Like you said a compression check wouldn't hurt, it will tell at least the condition of your motor. You can pick up a tester for like $20 from autozone I think. BTW is your turbo a BB? maybe you can get it rebuild or time for an upgrade?

yeah same place same dyno machine
streetz:I did 3 pulls and they were all 355-360whp on 7.2 lbs, my turbo is efficinet for like 30 lbs lol and 650hp, so the turbo isnt dying in that sense. I got a compression tester today will check it, if its not the motor time for a turbo rebuild.

Boris, what's up meng. Get your azz out to the car and do the comp test.

What you think was the cause of ur low compression?

To be honest with you no idea, this was the first time I did a comp test on my car ever. Im now looking for a dek swap and while the motor is out im also gonna check my seals on the turbo.
