Im using the 1st gen DSM metal BOV , but I cant even here that its working. I was told that these were pretty loud. Its in perfect working condition, just cant here it.
I trying changing were the vacume was hooked, to a larger vacume port, and it sucks the BOV wide open,and keeps it open. on the small vacume ports it doesnt even move.

whats wrong.

 

My dsm bov is way loud... Mines is crushed so i dunno

 

how do you "CRUSH" it?

 

Tell us abit about your setup. Is it vented to the atmosphere? How many psi are you running?

 

is your car moving? or in neutral? cuz the BOV will only make a sound when underload and in boost....

btw all the DSM BOV's i have heard are loud, except the one on my 4dr...but i put the stock rubber hose on the end so it wouldnt make any noise

 

Crushing it will only make it harder to open...thus keeping it closed if you plan to boost more than what it was origianlly designed for.

 

in other words: if you have a honda leave it alone

 

What about 14 psi? Any leaking possible?

 

im running it at 11 lbs and its pretty decent for what it is. its louder than i thought. if your running open dp ofcourse your not gonna be able to hear it. but then again u can still hear it its just a softer tone since your car is too fucken loud. so if your car is open dp thats your problem

 

I think the DSM guys start crushing them over 18psi.
