    I used one on my car a while back. Worked fine as far as I could tell. Just make sure you recirc it.

    When you are in boost and shift with a blow off valve, the engine will run rich for that split second that the air is released into the atmosphere (the injectors are dumping fuel and some air has escaped to compensate for it).

    If using a recirculation valve, this situation does not occur.
    thanks. I researched abit on the differances(yeah I try to read up before posting. anti-flame?) and liked the idea of the air going back into the intake without the loud blow off noise(there are alot of really loud blow off valves around here, gets old). Jim wolf says it reliable on systems up to 17psi(I run 12). now should i install it like this:


    (just a joke, lol)
