Really?
How's that working because I was told it wasn't big enough for the sytem.
I posted up a link to that very type a while back.
What level of boost are you running?

I am running 5-7 pounds of boost. I was wrong about it being a 38mm it is a 40mm bov. It has been working for me, the only thing I had to do to it is modify the spring inside, make it less stiff.

The bosch will bleed boost, if you are making more then 300hp it is NOT a good idea to run one. A cheap alternative that works GOOD is a 1st gen DSM blow off. One is good for about 400-450hp and two can work good to 800+hp or so.
