Default HELP!!!Huge HP loss!

Hey for those of you who havent heard a carbon fiber drive shaft is the real deal...the only problem is Im not sure how it will hold in a cold weather environment. If anyone knows please pm me or just post a reply. Also recently I have suffered from a huge horse power loss..The only thing done to my 07 STI is an Intake,recirculating blowoff,cobb master pully,and nur spec blitz exaust. I had the local dealership do a compression/leak down test and the told me they had to replace the o-rings. After my long awaited reaquaintance with my sti I was EXTREMELY dissapointed when the sti was still displaying the same attitude and power as a down syndrome-prius can someone please give me some peace of mind?

1st, what O-rings? do you mean piston rings? Did they pull your engine to do this?

and 2nd, how do you know you're down on power? Have you had it on the dyno or can you log and do a road dyno?

They just told me they replaced the o-rings..they did not pull the engine. heres what happens...I hit the gas..turbo spools..turbo meter cranks..holds pressure..rpms go up..but I speed up really slow...really slow. I know its not clutch slip cause I can rev to 5 dump clutch and it catchs fine. When I speed up there is only a strong pull for a second and then dies...

You need to find out what "O-rings" they are talking about then. If RPM goes up and speed doesn't there isn't anything else that it can be besides the clutch unless you are in neutral

You know what an O-ring is right? Just saying replaced the O-rings doesn't give any indication of what O-rings. Injector O-rings, MAF O-rings, IAC O-rings, etc.... You get the point right, there are many, many O-rings in many applications somewhere on your car. I only wanted to know just because a shop just telling you we replaced the generic O-rings is never satisfactory information.

PS: its still your clutch

Oh..yeah brain fart...im dumb I know. They were saying something about an Oil return line to the turbo...which made me think if there was a problem with the oil return line wouldnt the turbo not spool? How can I have them further test the clutch?

Well I new my clutch was on borrowed time but last night I loaded a car load of friends in mine for a spirited joy ride and noticed quickly that my clutch doesn't like 4 people in the car and full throttle 4th gear runs uphill. Its not that bad with just me in the car but sometimes when a clutch starts to go it only slips during high load situations.

you need a clutch. if it doesn't like 4 people, then it doesn't like full boost either.

Unfortunately Im not a local to the area...I dont know any shops around here and I have to go through the dealership..and needless to say the dealership here is not as good as the awesome one in jacksonville. I can say he hooked me up to the computer and no codes dropped.. I do think the dealership is shady though...when i picked up my car there were something like 20 extra miles then when I dropped it off...

If I was in your situation, I'd find a local tuning shop, "Topspeed" comes to mind if your in Georgia. Ask them if you paid them a service charge, could they give your car a once over, maybe pull the rom off the ecu, and tell you if the car is infact tuned or not, and they could give you a better idea of whats going on wrong or right with the car. A clutch would be the obvious route, but it could be something else too. Bottom line though, if your unfamiliar with the mechancial and tuning aspecs of the car, you need someone to look it over first hand to find out whats up.

Good luck

Trey

Hint #1- post in the right forum
Hint #2- don't talk down to people trying to help you
Hint #3- quit shotgunning threads every 15 minutes, especially when you have related threads elsewhere
Hint #4- do some of your own research. We love to help but we're not here to spoon-feed you



As I suggested in one of your other threads, TAKE THE CAR TO A TUNER/SHOP. At the same time, I hope you have enough money for a new motor, you may need one since you have those mods and no tune.
