We run road racing which I wouldn’t think that would make a difference if you run sprint. I pulled the thermostat out of ours (07 Leopard). Got tired of it sticking. When it’s cool (under 50 degrees) I put tape on the radiator and adjust water temp from there. We run between 135 – 150 on water temp but also run exhaust temp. We run ours before we go out for practice and before called to the grid on the stand until hitting 90 degrees.
