    prop is too tall plus your engine is a tad lean w/o the powershot too best if you get the powershot on there befor you burn a piston R2 with power shot and B1 Try a 14/23 prop

    I hope not! Possible oil leak places are oil filter, oil line from oil cooler to motor at left front corner of motor or possible o ring seal between Supercharger and block remember you had this off when you installed the B1 wheel ! Check where dipstick tube goes into block too! Check these locations I have sugested!

    I've been doing some tests down here in the Caymans withe the R2 and that thing works really good...

    Tried R2, C5-11, R5 Intercooler, R&D engine cooling kit, twin-prop and R&D FPR kit and the gains was where I expected them to be, actually even better...

    With the plate I tested, the speeds were 76+mph... So with a good plate like the R&D or VX plate, it will do well over 81+mph... And that's with NO powershot..

    Never did use a tack to read accurate RPM's but i would say its around 8400-8500rpm given the set-up used...

    Even have another set-up with C3-11 and stock FP with NO powershot and the ski performs really well with great results...

    It all depends on the temps and/or FP you decide to run with your set up...

    About the oil leak, which side of the ski did you notice this from?
