Not sure of problem, rpms going up fast

[dr gonzo]

Hey guys

Not sure exactly what to think here. It's been going on for a few months now but my rpm's seem to climb super fast, faster then they should on full throttle anyways. The car picks up speed but I have to shift almost instantly before the car goes over redline. I let the car totally warm up and it seems like if I do a small pull the car acts fine, however as driving for more then say 10 mins or so the rpm problem really starts, especially in a higher gear under more load then after awhile my lower gears start acting the same.

Like I mentioned, while the rpms are going up faster then normal, the car still picks up speed and does not really seem like a slipping clutch.

I have no noticed any strange smells and the car isn't smoking.

I changed the wastegate actuator today and no difference. while changing it I checked for shaft play on the turbo and it seems fine. I also changed quite a few vac hoses and clamps looking for a boost leak but did not see a difference. The car is also just not acting the same as it has in the past when I had a boost leak. Like I said the problem has been going on for a few months now and unless testing to see what the cars doing, I have not been hitting boost and the car seems to be fine.

I also changed the bov from the 2g to 1g.

The problem seemed to be worse a few months ago as well but when I fixed a few pinched hoses it seemed like driving out of boost got a lot better but under boost I would have the same issue

Plugs, wires, coils have all been changed as well

how much boost are you registering?

from your post seems like a slipping clutch is the culprit.

more load, the more it slips.

Well, he said the car is picking up speed like normal.

Maybe your car magically got more powerful!!

I'm running 1 bar right now. Any time I've had a slipping clutch in the past I've always had the burning clutch smell and total loss in power. However like I said the speed seems to be matching the rpms but my rpms just seem to be going up way too fast. Sometimes if I let off the throttle lightly the rpms will drop off a bit and the car seem to start pulling like normal.

Also, like I mentioned this has been going on for a few months now. Usually by now I'm thinking if it was my clutch it would be getting worse. A couple months ago however, even before I would hit boost my car would start having problems. However, after fiddling with a few things the problem has gotten a tad bit better and just seems to do it when in boost.

Its gotta be a vaccum leak somewhere....Not a boost leak. Im betting your car is getting a little extra boost and leaning out causing it to make a little more power than normal.

Thats what I was thinking. I literally dont have enough time to see how much boost I'm making because the car gets to redline so fast. Earlier when testing the car I was fairly surprised at how fast I was going and it gave me doubts about the clutch slipping because of the speed I was able to hit.

Also, when the car was giving me more trouble before playing around with the pinched hoses and replacing the bov, the car would stumble when I would get on the gas, even just a bit but since then that issue has gotten much better after fixing some things.


probably should have mentioned earlier as well that the car seems to idle a little high. it's usually idling around 1000rpm to slightly under.

ittle bit of an update. So I was literally walking out my door to go buy seafoam to look for an exhaust leak when I thought to myself, goddamn it's freezing out and I better go grab a coat so I don't go walking into the auto store with glass cutters showing through my shirt. So I fire up the car and started thinking hmmmmmmmmmm if it's cold enough to see my breath then just maybe........

I look under the middle of my car and sure enough I could see exhaust smoke and a bit of condensation coming from somewhere near the cat. I'm pretty damn sure that's my issue so I'm gonna take it to my dad's friends exhaust shop and get it fixed and will report back.

might explain why my car sounds so retarded when i try to hit throttle hard.
