    Riva pro series X upgrade vs. ET137 upgrade

    Which moves more volume of air? On paper they both appear to be the same. Does the ET have a slight edge?

    Boost numbers should be around 11psi/8100 and 13psi/8600 according to what Ive read/heard...

    Last summer my stock Xcharger saw those numbers.... I would think the upgrade would make more boost then that... I will be running the ET137 this summer, so i would be very interested in what people are getting with this wheel...

    Those are big numbers for a stock x charger..
    The ET140 is only around 15psi.. I cant see getting much more than 13 from the ET137..

    Cold water only is not gonna make a stock X turn 8600rpm. He list no mods, but is turning 8600rps. 8600rpm is above stock rev limit, so just wondering what mods he has to turn that many rpm.

    Lets see if you roll your eyes again...

    The Et has a taller blade Hieght and will move more air than the Riva upgrade.

    The mini Rude is one Bad mofo aswell. Or should I say the adopted 2rude.

    I have seen 13+ with a Stock X SCer also.
