loss of power at higher rpm

[mjjstang]

ok well I have been drivin my car a little lately and after a while ill get on it, but in the higher rpm it just feels like I have no power, and i hear some type of screech a litle bit, theres no way that the bov would make that sound right? i mean under boost that thing should be really tightly sealed. My buddy who hasnt driven my car yet, says its my plug gap, but its set to .28 its an s13 sr with gt2871r about 15 lbs. then after ive gotten on it it just keeps getting worse. I imagine it might be a clutch problem but I dont know, its just pissing me off. and the screech especially confuses me. btw its not a screech when i let off, its when im still on the pedal.

ok well I think ive figured it out, I had my boost gauge on a separate vacuum source and my wastegate on another, so basically the gauge was telling me something totally different, and UH OH I think iwas boosting at around 20-25 on a stock HG, well also i only have 555s which is probably not enough for 25 lbs of boost im sure. but anyway it seems ok now, maybe i was making too much power for my spec stage 2? well I certainly learned not to just route according to some diagram some kid from a forum gives me. time to use the old noggin and realize i should have put these on the same vac source to begin with, and btw i guess that screech i heard could have been something really bad, turbo still spins fine and doesnt seem to have any shaft play. o well we will see what happens, car still smokes a lil white exhaust tryin to figure out what it is, I just changed oil and it was pitch black which is a good thing. i donno any suggestions about my car. Thanks.

If you're boosting, and you're not accelerating, sounds like your clutch can't handle the power. Usually, if you're smoking clutches, there is a potent smell to it.


If you floor it from a stop, and your revs climb up, and your tach pegs with no movement.. then it's time for a new/better clutch.
