Procharger Bypass sounds

[A.Mustang]

Can anyone explain to me why some prochargers will make a blowoff sound that flutters very noticeably, and some prochargers will make a blowoff that sounds like straight blowoff with no flutter. And they seem to be the same kits, confused as to how some can make that loud flutter sound.

I have the red race valve and it is a regular sounding loud BOV. Maybe the standard BOV flutters. Normally that is compressor surge though

Some people recirculate the air back into the intake tube as a stock kit is designed (quieter). Some do not and leave it open (louder).

My bullet valve flutters under high boost situations after letting off. I want to see what affect this wastegate has on it though.

Mine just does a single woosh. Its just vented to atmosphere from the valve (non-big red) that came with stage 2.

You will hear your WG open, the Tial makes a slight high pitched sound. Got the eboost running today, gonna mes with the gate setting a bit tomorrow.

My fave BOV is still the hks ss, love the flutter and sound of that BOV.

I am going to install mine on Saturday.

Think I am going to put the eboost II and Nguage in the glove compartment.

Yup.

So there would be no hoses going back to that vacuum block procharger provides correct? Just don't want to mess something up lol.

no you still need that for vacuum reference to open/close the valve

Step away from the car. Lol

The bigger hose that returns the air back to the filter intake. Not the intake manifold.
