BOV Before or after the I/C on high boost setup? Simple question 
Should the BOV be between the turbo and I/C or between the I/C and throttle body on a high boost setup?

interesting... never thought about it. It would seem logical that you would want to closer to the turbo as possible, however, since the cold pipes are pressurized.. would it really matter as much?

Based on venting the inverse pressure wave caused by the throttle blade snapping shut, you want it as close to the throttle body as possible since it will contain the wave further from the turbo. In practice, I don't think it makes much difference.

I have mine after. I mounted it about 8 inches back from the TB. The BOV is supposed to release the pressure on the pipes when the TB blade closes, I figured I would mount it on the TB side of the IC. I cant see why it wouldnt work eigther way.

its good to have it close to the t/b according to corky bell
i never had a problem and plan on running 20-30lbs of boost this year in my other car
just don't buy a cheap ebay i/c and a greddy bov knock off

mine is close to the TB as well... I wasn't worried about blowing the tanks off ICs, but I had heard about containing the pressure waves by the TB as said above.
Also, when a BOV after the IC is open, the turbo (not creating heat because it's not pressurizing air) will pump ambient air through the IC and help cool them off when not in boost.

pressure is resistance to flow so the highest pressure point would be before the TB because that is the point where the flow is getting blocked off creating pressure at that point IMO i would have it closer to the TB that is where the spike will be seen first
I am a pneudralics specialist and that is no **** straight out of the book just changed it to a turbo setup as opposed to a shutoff valve

Ok, i have seem both applications... however, i remember seeing a subi' with the BOV mounted on the I/C. It was mounted to the top just off the outlet to TB cold pipe.
IM not interested in doing this but would this help out/hurt in any way?
