Help Sti making a noise

I am running a full perrin turbo back exhaust and a typhoon intake with a hks bov. My engine or something else is making a squeiling/horn sound after 3000rpms in 2 gear through 6 gear. I am not getting full boost its have a hard time making it to 6500rpms. Any ideas? The car is still under warranty, should I make an appointment with the dealership???

You bought that from the Jaguar dealer downtown, right? I could be wrong, but SOA might not touch it due to the mods. Could be a simple leak on the IC hoses or inlet hose, check all hose connections from the turbo/IC/bov. If no solution I would switch that bov back to stock asap and check again. Are you throwing any cels? Good luck...

 

i would have to say that that car is not under warranty anymore...

 

check for leaks in the intake system. also leaks in teh exhuast pre turbo.

 

i already went back to the stock atmosphereic release valve. I wish I had a check engine light on!!! Last time I brought it in to burnsville subaru, they were really cool about mods. I will check more hoses in the morning, if not I will more than likely take it back into the dealership and If they give me any crap about the downpipe, I will switch back to the stock dp and run it into a jaguar.

 

stock atmosphericreleasevalve?
is the maf plugged in? did you put it in flipped arround 180 degrees?
what exactly is plugging the hole in the turbo inlet where the bpv recirculation used to go?
check the compressor outlet to intercooler pipe.
that one can be a mother****er to get on right.
did you check for uppipe/header leaks?
did you reuse the gasket when the turbo back went on?

 

its the stock bov(atmospheric release valve). i am going to be checking the intake this morning and the intercooler pipes. this is the first time i have seen a problem with the car period.

 

if you can, also check the uppipe to turbo bolts.

 

We gotta start somewhere? How long have you owned this STI and when was your last modification (power-wise)? What was this mod?

 

fixed turbo inlet hose from intercooler clamp wasn't tight!!!!! YES

 

congrats....:rockwoot:

it's sometimes the simple things that gets us....

 

cool. good deal.

 

WoTVs and I found that problem on my car when we installed my DP. We tightened it up but then loosened it to adjust something and then forgot.

Ain't life funny!
