I still have the originally supplied ATI ProCharger blow-off valve installed...only difference is that I have it vent to atmosphere now...
valve seems to have been sticking open at the track yesterday...went from a normal boost climb to 10#+ to 7 and hitting a wall...
valve seemed to have stuck open on two passes and functioned ?properly? twice...
a/f is pig rich since the new larger FMIC, but we were afraid to lean out when boost was way off...glad we did not lean it out for the 7#'s because the next run it climbed to over 10#'s...
I need to upgrade the blow-off valve set-up...I would really appreciate any pics and specs on what you guys are running...
Thanks!

 

here's one I found today that I think may work...
and only $100...

 

The one I had looked different. Don't have any pics though since I sold it.

 

this one may work as well...looks like it will work with the hose I'm using now...no welding required...

 

My stocker has been flawless. I wonder if you should just replace it with another stocker. They are on Ebay all the time. I don't know if there is any performance gain from another brand/type, but I could be talking out my a$$.

 

SCIV...do you have the same original as I do...pic in first post?
Most people do not have this one...I think they changed it to a black aluminum one after I got mine...
mine is 4 years old too

 

this is prolly the one you have...maybe I can find one of these...

 

yup thats the one I had. It worked just fine no issues.

 

Yup same one. No problems so far.

That other one looks nice

 

im in the same boat. i had a stock one simlar to that and it worked ok but i deceided to go bigger and get a vortech upgrade and it kept opening at about 7 psi. so ive been wondering do supercharger and turbo bov work the same? i recently put a stiffer spring in mine but i cant test it yet.
