I recently just had my turbo rebuilt due to some problems the previous owner caused and now my car is acting very odd at full boost (21 psi). its hard to explain what it is doing but its kinda feels like im stepping on and off the gas really quickly. and from what i can tell the boost holds still. and it only does it at full boost. ive never had this problem berore or heard of it. any help would be much appreciated.

 

clutch slipping. I had the same prob and it was the clutch slipping.

 

really. so all i need to do is replace my clutch.

 

+1 definitely a slipping clutch

 

m in the same boat too. it started happening today for me as well. scared me a lil at first but then i could smell the clutch

 

wait a sec. i should smell the clutch if its slipping? because i dont smell a thing

 

what mods do you have??? read post #3 of this thread for a easy how to to see if your clutch is the problem https://www.evolutionm.net/forums/sh...lipping+clutch

 

my mods are: cai, hallman boost controller, walbro fuel pump, exhaust manifold, downpipe, after cat exhaust. and i will try that test later today when i have time.

 

i tried the clutch thing and its not my clutch thats slipping.

 

anyone? please help

 

are you tuned? if so when is the last time you changed out the spark plugs?

 

Misfire maybe? do you hear sputtering?

 

You wont smell your clutch if its slipping. Mine was slipping for 6 weeks and I just got a new one put in today. I never once smelled it. :-/

Also, your clutch at first may not slip in higher gears. Mine started slipping in only 2nd and a little in 3rd. Then it gradually started doing it in 4th and 5th.

Then over time, it massively began slipping.

 

i think my car is tuned because it has a rev limiter but i cant be sure because i bought it used. and haven't ever changed out the spark plugs.
I do hear sputtering though or like a really fast exhaust popping noise.
Also my car only has 40,000 miles on it and i have never burnt the clutch on it since ive had it but i dont know how long clutches last. but it doesn't seem like that.

 

help please!
