    420 dyno proven HP

    Here's some dyno results of my engine build done by Riva. This is a VERY conservative tune at only 17 degrees of timing and 22 psi boost. 420 HP and rec rider friendly. Should be fun!

    Wonder what it would do with 32 psi and race gas

    yes sir! 93 octane pump gas, 17 degrees of timing and 22 psi boost pressure.

    I was running 23 degrees of timing before I sent the engine off to be built up. There's plenty of room for more power if I need it

    Also, this is with the Riva turbo kit/Riva intercooler setup.

    Jerry, I have a quick question for ya: Can you run 100LL AV Fuel in these newer Yami Skis? I don't think they have a CAT do they?

    No, they don't have a cat. No need to run AV gas unless you are running high compression or a lot of boost and you will want programmable ignition to tune for it.
