I searched, but couldn't find what i was looking for. Sometimes when im in like 4th or 5th gear and i full throttle it, the rpm's just shoot up, but the car isn't going much faster. And suggestions. I got USDM sr20de, t25, 370s, bkr7e's gapped at .30, stock wires, fmic, jwt ecu. any suggestions on why it does this? Oh, and im running 11psi.. if that helps any

Is the tach just showing the RPM's climbing or can you hear it too? If you actually *hear* the motor revving higher, your clutch could be slipping. Otherwise someone with some more knowledge of the tach. and how it gets it's signal is going to have to chime in.

if the rpm increases but the acceleration doesn't i would say clutch slip

Sounds like a clutch problem to me too.

Im been using the stock clutch ever since i got the car and turbo'd it. I could open throttle at a low rpm and when it hits about 5k, it climbs. and yes, i can actually hear the rpm's climb. I never experienced clutch slipping **, so maybe this is the prob?

I agree, if the tach suddenly rises, but not the speedo, then you are slipping the clutch. In colder weather, sometimes I would spin the tires on the freeway, but couldn't hear it, so I feared for the clutch, but I noticed the speedo would "jump" as well, so it was the tires, not the clutch. Could be that a clutch adjustment is all you need (or stickier tires.)

Clutch adjustment aint gonna help a slipping clutch.

That is definitely your clutch slipping. Not too big of a deal, just make sure you get one that can hold the power your putting down.

Im putting around 230 hp. Hows the exedy clutches? it's on ebay for 130.. am i wasting my time?

Well those exedy clutches that go for $130 are OEM spec clutches, not high performance ones that can handle more than stock HP. Besides if you're gonna go thru the trouble of dropping the tranny, put something in there that you're gonna be able to leave in there for a while. I hear that clutchnet seems to be pretty good, I myself have a ACT Heavy Duty Pressure Plate with an organic street disk. Hope this helps!

I think the Clutchnet group buy is still going on... PM Goneturbo about details!

Are you sure you don't have the clutch cable too tight, that could cause it to slip.

Clutch is slipping. Happened to me without a turbo.
If you're gonna do a flywheel, it would be a great time to do that too.

i'm surprised your stock clutch has lasted this long. My stock clutch was dead after only a week and a half of boost

ya.. the stock one is holding up pretty good for 49,000 miles n/a hard driving, and about 12,000 hard turbo driving.
