Does turbo / wastegate sound change with more boost?

I've been running my setup with about 400whp and will be going up to about 550whp.

To achieve this, same turbo but more boost (pressure).

I'm just wondering, because i will be making more boost, will the turbo whistle louder effectively changing the sound the car makes out the exhaust etc?

Same again for the waste gate, because more pressure, surely it will be louder? and sound cooler? :biggrin:

typically will the car overhaul be louder or quieter with more boost? This sounds a obvious question but people say and i've noticed that turbo cars are quieter than the NA variant of the same model. This is pretty important because i currently pass sound levels for my local track.

Yes, i'm getting excited now, the car is in the garage!! hopefully in a month's time.

I might post up a build thread at some point.
