    Engine faliure...

    Well... maybe it wasn't a good idea to put a racing cam and 14 psi supercharger on a 174 hr. engine

    Not yet sure exactly what came apart but it's in the aft cylinder. I can't even break the sparkplug loose... probably mushroomed by the piston

    I'll post more when I get it apart.

    Luckily, (if you want to call it that) I had bought a spare engine recently and it should be here soon. Just didn't think I would be putting it into service so soon

    Jeff

    BTW... unbelievable acceleration and 75+mph @ 8350. Wish I could of fine tuned the impeller before it blew.

    That sucks. I hope you are able to use most of the engine still.

    No, I installed the Riva upgrade (on two skis). I suppose I could have errored during the install but the other ski has over 5 hrs with no problems. I will be pulling the vavle cover after work to see if everything is in place.

    Rude SC, fuel controller, 50lb injectors, Riva valvetrain upgrade, XS IC, RR ECU, 4" intake, etc. etc.

    I'm being optimistic and hoping it was just fatigue... rather than an error installing something

    a 174 hrs isn't a lot 4 0ne of these motors ive heard of riva valve train letting go, c if the valve tip broke off or if a valve keeper came off
