    I've heard the engine needs the backpressure to help slow the SC impeller down, which would make your clutches slip less.I've had no problems running one, but I don't any longer. Save your money for performance mods.Much less money to just buy a set of les's or jerry's (cough, cough) new metal washers. BRP engineered it without one for some reason

    the pressure builds up in the tube from the SC to the TB when the throttle plate shuts, and helps to slow the SC impeller.

    i got ya, but wouldnt you want to let it slow down by itself like with a blow off valve rather than force it to slow down by the pressure...

    Please search for this. This has been a HEATED discussion many a time.

    I'm not sure where I stand, but all I can say is Riva is/are the only ones using it.

    Les Cooke, Mark Underwood, and Franko Detorri are NOT advocates of a BOV... those 3 respectable names all agreeing says something to me, lol

    the theory is;when the throttle closes from full to O there,s a large surge as you shut the door on the air flow.... BUT you shouldn't doo that any way? Roll on the gas and roll off the gas... No more problem

    I dont use a BOV. I blocked the BOV port off on my Riva Power Cooler kit.
