What procharger is that, my maf is located on top of the intercooler, i see yours is in the maf tube, I had that sound also, my bov was not closing completely, got it adjusted and it went away.

 

 

Its a P-1SC-1 just bought a month ago, Here is another picture of my engine :



You had the same problem as I did? do you have the same red plastic BPV?? I found mine next to the intercooler.

 

Any other comments?

 

i think it should be louder mine is and i have a p1sc .... you may want to double check you tubing and make sure everything is really really tight... also procharger does sell a race valve that is louder...and i have been told there are after market ones that are alot cheeper....

 

I checked and everything looks tight, maybe I should take the car to the place where I got everything installed >_<

 

I think its called compressor surge the sound that you are hearing, talk to some import guys that know there stuff about turbos, tututututu as you called it or the shuttering of your blow of valve if I remeber corectly should be kept to a minimum, if it shutters under hard shifts with boost its set incorectly. I know for a fact that is is supposed to sound on way not the other, pretty much when it shutters its not letting all the excess boost pressure out fast enough hence putting back pressure on the turbine, but then again I could be totally wrong

 

Heres some good info ya its related to tubos but what you have is a belt driven tubo

"another" thread with some unclear info http://forums.streetfire.net/archive...hp?t-1818.html

pretty much from what I read flutter is ok at low boost flutter @ high boost = comp surge

 

ok i didnt read the responses but the reason you are getting flutter is because the spring on your bybass valve is tightend too much, if you loosen it a little you can get it to flow correctly. if you see my other videos it no longer sounds like that

 

Oh its your car!! first of all allow me to say you have really beatiful mustang, I like the way it looks a lot, coming back to the sound situation, what do you think? should I just leave it like this? so its nothing wrong with my Procharger? because one of the guys that made a comment here said that it looked like the belt was slipping a little bit for me it didnt seem that but maybe I´m wrong.

Thanks Anb.
