My Paxton does the same. Watch the drift video and you can hear it well.

Sounds just like my Paxton, most of the heavy duty blowoff valves sound like this. I believe we have duals on ours.

Cool vid but it makes me cringe whenever you go near that wall! lol

wow.... you guys are silly.. there is nothing bad about it. The shuttering sound is a staggered release of the pressure it has built inside your intake manifold. Sure the loud woosh draws attention on a 100% to ambient BoV but when you shift and it goes WOOSH then you get it in the next gear, the first thing the car has to do is recompress the colum of air inside the manifold. The "Race" bov are sequential for the minute gain you will see when shifting or any quick on off of the gas.

Also, these are not that bad on internals of your turbo / supercharger. Get to high boost and maintain it fairly steady, or get to high boost, drop to huge vacum, go to max boost.

Put this another way, a off the gas rolling pressure on say my car, is -13 PSI. A good Paxton kit is like +9PSI boost.

Sequential
-13PSI
Get on the gas
+9psi
Shift start, off gas
+6psi
+3psi
Shift end, on gas
+9psi

Or.....
-13 PSI
Get on the gas
+9Psi
shift start, off gas
-13 PSI
Shift stop, on gas, BOV slams closed, engine already at high RPM
+9 PSI



The sequentials really are better, aside from sounding cool, but with a more complex mechanism, there more expensive to make, and more potential parts to fail



Also, someone should note, USE THE SEARCH.....theres been a few posts like this recently.

Okay, so you're saying if i get the race valve from procharger it will make that fluttering sound? I just wanna be sure before i pull the trigger.

Thanks

I cant be 100% sure, but you know who would know:

If they cant get you what you want, you may need to do your own setup with some aftermarket bov in a custom setup

if it does work i need one of them too!

isnt there someone on here who has a procharger race bypass valve that can chime in??

If you put that race valve from procharger its going to be like 20 times louder than the one in the vid. I've heard it the red race valve vented to atmosphere and it was almost like you couldnt hear after the dude stepped on the gas and it let out the excess boost. It also vents out any air that is being created at idle, which gives it a really cool jet sound almost. Definentally something to get if your into really loud that things that will make people think "woh." haha. But to answer your question, yes its going to sound ****in awesome if you get the race valve.
