massive power loss

[hookups333]

Ok my car runs real strong up until 5000 rpms. After 5000 the cars acceleration decreases but the rpms shoot up a lot faster. Does anyone know what could cause this?

valve float?

stock h/c/i and valve springs? how many miles?

Sounds like a slipping clutch.

Standard or auto?

I would have to guess that it is either the clutch or torque convertor...

ya i wasnt even thinking about a slipping clutch. stick it in 5th at around 40-50 and floor it and see if the RPM's shoot up

If it's a slipping clutch you'll know in a couple days probably. Mine went from nominal to terrible in about 2 days. Got to the point where I could have the car sitting perfectly still, put it in second, let out the clutch and the engine wouldn't even notice....It would just idle...like a stupid idiot.

Sounds like a slipping clutch.

+1 get a t56 6 spd viper spec transmission and put a nice mccleod racing clutch in there.

On a more serious note, put it in 5th and stomp on it. RPMS will probably shoot up about as fast as if you were in neutral.

not clutch because i powershift into second all the time and its real good. i got an ecam with stock everything else on the inside.

from what ive heard powershifting is not good AT ALL.

Perhaps its time for more spark?

It messes up at 5k even when im not being hard on it.
