    DIF in between RUDE 2, ET 68-140E, Rude 3 with Riva ECU 8500RPM

    Did someone have the numbers for the ET 68-140 Extreme in psi by RPM
    Arts webpage have only 16-16.5 lbs @ 8750 rpm but my RIVA ecu is set up to 8400-8500 and dont wanna go any further....

    For example:

    RUDE 2 ET 68-140E RUDE 3
    8100RPM 13-13.5 15

    8300RPM 13.5-14 16

    8500RPM 14.5-15.5 17

    If some PSI numbers are wrong, please correct me..., i take this reading from other threads
    many thanks in advanced...

    KIT 4 Engine-Tech 68 -140 Xtreme LE light edition New and revised over the standard ET Xtreme the changes we did are effective ( A completely new blade and a revised hub contour) Much lighter.This is the big daddy of them all this our own custom charger with 16-16.5 lbs @ 8750 rpm of boost and with our high blade and blade geometry , contour combo, ( Complete Charger $1699.00


    They are both 140mm (differently designed wheels albeit) Correct but the ET Charger has a refined housing that is a bit better.

    Another interesting bit of info. i back to back tested an extreme LE against my rude3. The rude 3 made 16 psi @ 8600. Then switched over to the extrem with NO other changes what so ever and saw 15 PSI @ 8560. Speed was pretty much identical. These tests where made within 15 mins of each other so there very accurate. FYI prop was a 12.5/24 pitch with 83mm nozzle and speed was right at 86-86.5 with both
