so like the title says i installed my upper intercooler pipe and for some reason now when i start to get into the higher rpms and spool hard the cars making a whistling noise its like im running a supercharger not a turbo .. any ideas why? buddy of mine has same intake and upper intercooler pipe but an aftermarket bov where im running the stock

 

If everything is installed correctly and securely, you either have a boost leak or it's the normal intake sound. An open element filter will drastically change the way the car sounds. I got a little confused by the post. You installed upper intercooler piping and an intake, right?

 

no i had the open filter intake installed for awhile b4 i put on the intercooler pipe on and the sound started happening after i installed the intercooler pipe

 

Boost leak

 

It's just a boost leak. Prolly need to tighten the end on the intercooler. That's where the problems are most of the time.

 

i wrenched em down pretty hard, thanks for the help guys i gotta take a look at it tm

 

I had a similar issue with my nisei uicp, tightened 10 diff times, uninstalled completely, reinstalled, wrenched the hell out of it a few times and seems like no more leak so far. I'm afraid of tightening them down too hard and damaging the pipes but I guess even the aluminum of the pipe is reasonably strong

 

Could you make a video so we can hear? That will help us help you. Its most likely a boost leak though.

 

ill record 1 tn so when other ppl search for this problem they can hear what it sounds like

 

When you installed the piping, did you use hairspray to secure the couplers?

If Yes-- did you use TBolt clamps or the supplied hoseclamps?

You may have overtightened the hoseclamps, which broke the hoseclamps.

 

Is it the one-piece UICP? How did you install it?

I have the Nisei one-piece as well. The trick to installing it is to fit the turbo-UICP coupler+clamp onto the UICP first, secure the clamp, and THEN install it.

 

I used to think that tighter was always better. CBRD posted up something one time saying that overtightening can cause more leaks. They do a leak test before every car goes on the dyno, so I'm sure they've seen a lot.

But... Just as someone else stated, if you used the normal worm clamp hose clamps, you may have broken one. If you tighten them too tight, they start to twist and can actually break or bend the little slots.

 

i didnt use hose clamps it came with Tbolt clamps

heres a clip http://www.youtube.com/watch?feature...&v=61VtcW1znGI

 

loosen the tbolts-

spray soapy water (johnson and johnson baby soap works well) between the coupler AND the pipe... and the coupler AND the clamp-

dont overtighten-

Boost leak test your ride, and make sure that you not only fasten your bolts the right way, but make sure that you inserted your piping all the way in.
