    7.5 lbs of boost as per dyno gauge

    Wierd eh??? 7.5 lbs of boost with an riva wheel ... I would think well into the 8s maybe even 8.5 ... proof that the rive /vortech DOES NOT MAKE MORE BOOST just brings it in way quicker

    You better get ur gauge calibrated cause thereis no way in the world the riva imp makes a full 2 more lbs of boost then a stocker

    Anyhow my acceleration as tremendous .. i walk rite away from 2 stock rxps and my ski has a riva cold air intake and now this imp .. I had problems with the 2 rxps b4 so im sure this thing made a huge difference ...

    70-75 degree air i run 8.3 psi with a STOCK sc impeller... i would imagine a vortech would put me over 9 in the same conditions... lucky for me, i don't really see 90+ degree air out on the ocean-front long island
