    Heat VS RPM's?

    On a hot day you can lose 100+ RPM's. Having a cold air intake such as the Riva rear air intake and having a cooler thermostat will virtually eliminate heat fate.

    Winter vs Summer I'd say on a sc motor loss of up to 300rpm's.... Naturally aspirated usually 100-150 rpm's. Thats just my experience. Just when ya think ya ski is running great the heat wave rolls in and knocks ya dick in the dirt....

    I concur! I've witnessed a 250 rpm change going from 68 degrees to around 98 degrees... humidity also played a part in this. All the more reason to have the interchangeable nozzle rings... it will help keep your dick out of the dirt

    Sorry Boosted, but when it's 30 degrees here and 80+ there: you suck...

    This will be my families first summer with the RXP and RXT. In January the air was 49 degrees and the water was 54 degrees. The RXP was turning 8150 RPM no problem.

    We ride Lake Mead. The air in the summer is 105+ degrees and the water towards the end of summer gets into the high 80's. RPM's should be way down.
