    Another trick I learned from somebody was the installation of a 
thermostat somewhere in the pressure side of the engine water cooling system.
    If I didn't have a thermostat I'd have to run the engine long enough to 
get the entire coolant tank (no place for a heat dissipating(sp) radiator or 
air flow through same) up to say 160 deg before making a pass. At that point 
I'd be 50-60 degrees away from boiling, plus having 15 gallons of very warm 
water 12" away from me and my blanket-like fire suit on what was a hot and 
uncomfortable situation to start out with.
    By using a thermostat I can warm the engine to 180 deg while leaving the 
coolant tank water at ambient temp. It gives me better cooling during the run 
as well as a more comfortable ride.
    At the end of the pass the coolant tank (and the temp inside the cockpit) 
is much less than if I'd pre-heated the coolant to 160 deg............Ardun
