    ET 137x4MM complete charger

    No need to have 2 chargers sitting around, and have decided to keep the XXX, so this is for sale. It has 3hrs of run time on it, with the slip still holding at 16lbs. It produced 15psi at 8900rpm according to my AEM boost gauge. Charger has the viton seal installed as well. 1000 shipped in the lower 48.

    It showed 16psi just shy of 9000, and more likely would touch 17psi at 9k+ or with the addition of a reground cam.

    It was a brand new/never used X charger from a 2012 ski.

    Sorry buddy, but how about you try reading the original question? It was in reference to the XXX, and not the ET137.

    Between the Riva XX, et137x4, et 68-140 and Riva XXX, it's a toss up between the 68-140 and XXX. I have seen a lb more of boost with the XXX, and the way it builds boost, is incredible. To me, the 68-140 felt like it was all top end boost, while the XXX has more midrange along with the stable top end. With a holeshot, the XXX, wants to throw you off the ski. I never had that sensation with the 68-140, until it reached higher in the rpms. For a 137mm wheel, the ET 137x4 gets my vote hands down. It smokes the XX in power delivery and outright thrust.
