Installed Buschur FMIC, upper I/C, and MAS pipe. Had a boost leak, but got that taken care of and now am bosting 20 psi to redline. My car whistles, but I thought it was a leak, but it still whistles even after I fixed the leak. Is this a normal noise when putting all this stuff in? or could there be a crack in a weld or a faulty BOV????

 

My car sounds like a BPU Supra TT with the Buschur MBC.

 

4 bngr- SO you have the whistling sound too?

 

you should ask David about it or give him a call.

 

I only have a B&B turboback. But my turbo wistled at open throttle even when it was stock. Is this bad?

 

I mean a LOUD whistle, not a hum. Sounds like the new supercharged cobra

 

Im guessing its normal as everything seems fine and it feels fast as hell

 

Yes....thats normal. With an intake the sound of the turbo is magnified 10x.

 

I have the aem intake and it screams like an eagle on full throttle. Very loud whistle. Peace...

 

I have the same problem after installing mine as well. Did not have the problem on my 2g, nor have I ever heard it on another car. When I called Buschur, they stated that it was not normal. The sound is annoying. I have pinpointed the timing of the whistle. It appears to be more evident on vaccum vs. boost. I can here it more when letting off throttle gently. Sometimes I here it when parked. It is indeed coming from turbo area, because I can hear it through air filter. It does not always so it at idle. Its really f'ing annoying.

 

It's called the sound of your turbo spooling

 

Mine also whistles and I have the Buschur Stage 2 mods. I was told by Buschur that it was normal and was the mbc.

 

Thnx guys. Glad to know its not anything getting ready to blow up People stare as I drive by. They prolly think my car is gunna blow up. Sounds like a jet taking off!!!!!!!!!!

 

Why do I consistently get different answers from Buschur. Guess there's a BIG gap between Tym and Jarrod. Lesson finally learned! Wait 2 days for Tym to call back.

 

Holy crap.

This is what I can tell you guys. Not sure why there is mixed information. Maybe it is the mixed problems we heard and the times it happens.

There are three things we can come up with that will make your car "whistle".

#1 Reason is the turbo making the sound, this is going to happen under some type of acceleration. Part throttle or WOT it can and should happen.

#2 The 1G BOV's are known for making a whistling sound just before the valve closes at part throttle driving. This is caused from the air going past the actual valve and the seat, it is usually more noticable with a vented to atmosphere BOV. You can usually only here it when you aren't on the throttle hard, like normal driving or parking and such.

#3 Not super common but happens. There is a small bleed orifice on the side of most manual boost controllers, these can cuase a small whistle too.

Whistle while you work...or drive.
