    Stock Motor

    Will a stock motor with springs, hold 8800 rpm?

    Im going from R2 to R3 to see full potential of my wheel, but I would like to make sure i would be safe. I would like to make sure Stock internals (excepts Srpings) would hold that amount.

    Anyone would like to chime in?

    I heard ,above 8500 ,value train being to float ,
    you need upgrade value train.

    Wow,you might try custom request for 9000RPM+ limit,
    or remove RPM limit completly !

    R3 so hot right now ,
    we might have alot of real test/use soon .

    I would not do it, but I may be bit biased.
    Remember, when someone says 8,800 rpm or higher is just fine if something does happen the money does not come out of their account.

    according to r&d it should be fine turning those rpm's after you install the springs. BUT

    the real question is what wheel you have, how much boost your gonna throw at it, the stock rods can only take so much

    With stock internals @ 8800rpm eventually your going to loose #1 or #2 rod and/or piston. Murphie's law states that the rod will punch a hole in the side of the block. But the fun part is putting it all back together.

    Not if, but when.

    8600 would be a safer level but over time it's still a risk.

    Good luck.

    What is it that make people feel they need to run these huge boost wheels on recreational setups? I seriously don't understand it.

    they want to lead the pack, lots of 18-20 pound sc setups running around in miami right now, the competition is serious down there,
    in short words the guy you beat this weekend is gonna spank you next weekend, so you have to up your game to beat him again. lol

    I figured it was a Miami thing. Then they'll blow up their ski and be cussing Yamaha and the aftermarket parts manufacturers, and whoever built/set up the ski.
