    It would work but you need a left handed crescent wrench to install it..

    BTW, there are tons of threads on this forum that would point you in the right direction..

    If you guys don't know what you're talking about don't make shit up, there's a boost clamp but no SCOM for the pre-2014 SHO skis. At 7500rpm he's not on the limiter and that (and the boost limit) is the only limiter on the pre-svhos.

    The problem is that 13/22 is too big for the stock wheel. Turning 7500rpm is not going get you moving past your current speed. You could upgrade the IC to a Fizzle and you'll gain some more RPMs and speed. Or you could just depitch the prop 1 or 2 degrees as most run a 13/20-21 with your mods and stay just under the limiter. The other option is to flash the ECU and really depitch down to 13/18 or so to get your RPMs up to the 8300s but I'd still upgrade the IC with that too.

    I agree that prop is too big. I'm not sure why Riva recommends that pitch for those mods except to keep you off the stock 7800 rpm rev limiter. I ran about the same speed with a similar setup. With a R3 it got me to 71.1 at 7800 rpm.

    i was running a scat 13/23 with a b1 wheel, vflash r2 and fizzle getting 74.6mph and even that prop felt too tall.

    i think the next step for you would be the same as above, reflash, upgraded wheel and intercooler.
