    I'd say air temp.

    That was my initial thought, then i considered how much less efficient the I/C would be with warmer water.. Anyone else got an opinion?

    I would think Air as well, but I think I read somewhere that
    the water temp due to the I/C is more effective.\

    I do Not experience heat fade as much on my lightly modded
    GTX as I do on my RXT.
    Could be lack of IC on gtx OR that I'm pushing more boost
    on the rxt

    I've never noticed heat fade due to riding my ski for a long period of time and beating on my ski. The warmest I've ever seen my lake temps is 73*F so maybe the water temps going through the IC and cooling the intake temps does have an effect???

    Now I have noticed changes in RPM throughout the season due to increasing air temps, water temps, humidity, and lower air pressure. I usually lose around 100-200RPM from May to mid July.

    I'll tell you what, there is a HUGE difference in how snappy the throttle is depending on water temps regardless of whether it's 70*F out or 40*F. With water temps in the 50*F range or cooler my ski is nuts!

    new thermostate will help the motor run cooler in the heat.
