turbos spooling?

Or a boost leak

 

[NuffNuff]

I had this last week after fitting a new Intercooler. Tightening the hose clamps didn't help. They had to be taken off and reseated. No problems since.

Boost leak I would say.

But in saying it was a boost leak why wasnt this whistling noise happening with my standard exhaust?

Welcome to OzVR4

Does your car have a boost controller ? Is it standard boost or you upped it ? Because alot of the times when you add more boost the turbo's spool up faster and make like a little whistle noise. But saying all that, honestly could be anything without hearing it .

Edit: just read your last comment, did you get a cat back exhaust ? full exhaust ? or just a muffler ? Again i think ts the turbo's spooling up faster and making a whistle style sound(because you letting your car breath better), as soon as you let go of the gas does it stop the noise ?

What other mod's did you do before the noise ?

This is what happened to me when I had a turbo back exhaust fitted along with a Varex twin tip muffler. I thought I had a boost leak but after getting it checked it wasn't a boost leak, it was the turbo spool noise being way more noticeable than before.

How did u get rid of the noise?

 

[storm_detonation]

It annoyed me at first because I thought it was a boost leak but now I love it, I mean you can actually HEAR the turbos spooling, cool!

I think if the sound is the turbo spooling you could keep the Varex closed there shouldn't be much noise?
