Thanks for info.
Don't worry pp600 lol. I just heard stories of the AXYS running cooler. Probably just the TRS kit Poo installed.
Reason for asking is I have been hoping to some day find a bigger impeller and housing for my ol' Pro that has not been completed yet. I don't see anything yet I want to replace it with so I continue.
The aftermarket makes oversized impellers and housings for dirt bikes to help in the trees and hills and they work.
With marginal cooling and bigger-taller tracks, all sleds today, if adding NA HP, it becomes a concern (if they have a gauge to watch).
So I'm looking for a way to get rid of the heat, without adding weight, or needing to build a 87 octane motor.
