anybody remember when i had my gst i got smoked by a chevy malibu 4 banger and come to find out my turbo was gone, sooo thats what it could be, check and see if it has alot of shaft play even if it doesnt smoke...

 

if he is making boost I dont see how you can think its the turbo.

 

cuz my turbo still made boost, it didnt go past 10 but still

 

yea his is going past 10 PSI at that. and its holding

 

yea my stock turbo is still strong, probably about 9k miles on it...didn't know much about turbos so i had it rebuild by forced performance. i've checked everything that i know of and i'm clueless. i'm plannin on getting it dynoed then running the track again

 

how about a compression test?

 

The clutch? Or a boost leak? I know one time when my car would go kind of fast and then stop pulling it was the Sorry POS Clutch Masters slipping under load. It would hold okay when I launched and through parts of second, but then would start slipping and cause the car to not accelerate any more. I don't really know man...good luck and hope you figure it out! Or maybe try installing S-AFC, that’s my friend told me.

 

If you bothered to read the thread, you would know that the car is an automatic, and someone else JUST got corrected for saying the same thing.

 

lol yea the car is AUTO so i don't think i would need to worry about clutch...car runs great tho. we'll see what's up with her

 

That still doesn't mean that you don't have a leak. It could mean that the turbo is spooling 12-13-14-15 psi and the the stock valve is trying to keep it there.
