I’m thinking about buying one of these for my race bike.

The temperature was running around 210-215 basically all the time and would run over 220 as I would pull into the pits. My bike has a thin head gasket and degreed cams and I use just plain water and water wetter. Made 128hp at the wheel at 180 degree water temp and 126 at 210. The hp gain from lowering the engine temp would be minimal but I’m mainly concerned with engine longevity and keeping it from overheating. Thoughts?

I'd try running a higher pressure radiator cap, as a cheap experiment..... the cooling system will be more efficient under greater pressure.

I am running the graves radiator cap and no thermostat with engine ice and haven't really had a problem with similar build to yours.
