Blow off valve placement..Does it matter what side of the IC?
Searched for this discussion but could not find anything.
I use to own the CFT turbo s2000 monster but after having a kid i had to sell it and get something else, I bought another s2000 and I currently have a thread on the build.
I bought the Inline Pro turbo kit, and unlike my other turboed cars, the BOV is on the hotside of the piping versus the cold side.
Is there and issues with it being on this side, I mean obviousy its proven to work since there are 100s of Inline Pro'd S2000s out there, but I just would like to hear more opinions on this setup

I've seen this argument before and from what I got it doesn't matter. It's in the forum here somewhere, but it was posted that it might be better since the BOV is letting out air faster since it's closer to the compressor. There was a "disadvantage" but I can't remember what it was.
I don't think it matters really as long as the pressure gets released....BTW full race intercoolers have there bov on the end tank on the hot side, and im sure if there doing that its must be fine..
There seems to be a couple thoughts on where the "best" place is.In reality I don't think it matters.My decision is based on the cleanest place for the particular setup.
Personally, I would put it on the cold side. You might recover boost a hair faster in between shifts. I dunno, it just seems more efficient to me. In reality, I dont think it matters enough to make a noticeable difference.
Sounds good to me, like i said im sure it doesnt matter because 100s of peeps are runnig the IP s2000 kit with this setup and doesnt seem to be an issue

Actually, putting it on the hot side is more efficient.
Instead of venting colder air which has already passed through the FMIC, you will be venting hot air. This puts less strain on the FMIC, although miminal, it should improve air temps if the FMIC was constantly maxed out.
The other reason is that compressor surge is air pressure kickback between the compressor wheel and throttoebody. The FMIC is a source of restriction, so a BOV on the cold side may not be seeing pressure that is occuring between the turbo and the FMIC.
I noticed on my turbo IS300 that I had this minor surging that I cannot get rid of... Swapped BOV's, changed vac source, line size, etc.. and I noticed even if I physically jam the BOV open, I still get a minor surge. Voila, I moved the BOV to the hotside and the surging was gone. That was enough to make me believe that BOV on the hotside works wonders.
