    Speeds are low...or are they

    mods are in my sig but here's a list:

    gen 2 wheel
    xs
    42's
    3" intake for now
    gutted waterbox
    resonator removed
    solas 14/19
    worx grate
    holes filled
    bucket timmed

    my best speed was last saturday 71.7 at 8050rpms
    air 89 water 85

    im thinking i should be higher than this...kinda boring for the amount of money ive spent to get from 67 stock to now. whats wrong? or is it?

    YOu might try the stock grate or riva and see if you pick up over the worx if you looking for top end.

    change out the grate to a Riva
    check your oil level
    silicone your intercooler blockoff like hell
    check pipes for boost leaks
    check supercharger slip moment
    make sure there is no damage in your pump area
    you may want to check your engine alignment as well

    You should be pulling a 15/20 4 blade those RPMs with speeds 75+

    i am looking for top end just to see what i can get out of the boat with this set up, ill switch back to the stock and see what happens. what kinda speeds should i be lookin at with that setup skoepp?

    cosmic:

    the prop i had was a 3 blade, definately not enough power to pull that. shoulda tried a 4 blade. with the 14/19 and this set up with no leaks and everything good, what speed do u think?

    this seems almost right to me?? Looks like you have about another 100 rpms in there somewhere...

    Your parts choices are OK except for the 14/19 ... put a 15/20 Solas 4 blade impeller in there, make sure there are no boost leaks and you should definitely hit 75+ with that setup.

    His RPM's seem too low for that setup with that prop. I'm leaning tward boost leak, or mainly SC slip. How many hrs on those clutches, and what kind are they? What's your evevation ? A riva grate, and 4" intake will help lots.Also How many hours on the prop, and wear ring? Use BRP oil, and make sure it's not past the middle of the two bends on the stick.

    elevation is 697'. Had sc rebuilt 10 hours ago, riva metal washers, slip i dunno that may be a little over my head. dealer installed the prop same time as sc rebuild alson along with the gen2 wheel. wear ring was replaced maybe 12 hours ago, looks fine. brp oil is in, will check level, forgot about that. 8100rpms should be my goal right? 8200 is on the limiter correct? im trying to decide between rear air and the fizzle on the intake, but thats good for another 100-150 rpm.

    also, can i bend the my 14/19 to 15/20? im still learning in that area also

    U can de pitch the prop to get some R's ,but u should already be on the limiter (yes 8200) with that prop. I'd set for 8100-8150. Usually after break in on the clutches thery need to be checked for proper slip, and sometimes shimmed,then they will be good for a long time. U should see 74ish and more with a 15/20 solas.
