    I would try and avoid thermal shock and run a richer tune up to keep EGTs down.

    Springs and retainers, injectors and SC wheel. I would go with a 19 or 20 psi wheel. You may need exhaust also. You will need to spin the ski to 9000 to 9200 rpm. The 13/18 may need to be tweaked...

    The ARP stud is a M11 and is the lowest grade stud they offer. The recommend stud torque is 72 foot pounds. 85 to 95 is way too much. You have to use the ARP fastener lube also. I just torqued my...

    I agree 100%. Total BS. I bought a Motec and found to many features locked. I have been working on a FuelTech. It got slide lined when my motor rebuilt went sideways. Motec is a nice system, but...

    What did you torque the studs too? And did you use the ARP fastener lube on the both sides of the washer and stud threads?

    What water temps do you run in and what octane fuel are you using? A properly tuned and cooled motor should not crack the head at the Stage 1 level.

    I have been running stock fuel pump on my Stage 3+. I did because the ski was new and still has low hours. Now, that ski is 4 years old, a pump upgrade is a good idea.

    Sounds like a fueling issue which would be a really rich tune up. Maybe you killed the sensor before you got the tune up fixed. The plugs would have been killed too. There is no O2 extension, but...

    Depending on your conditions, the O2 sensor can go bad fast in two seasons. If you keep it in all the time, watch out. I find when they read high at idle they are done.

    The gear moves on the shaft. It is just pressed on. It can "walk away" from the super charger clutch and you have not boost or spin on the shaft.
