However, my calculations also indicate you may have to hit as much as 150-160 MPH before your cooling is able to keep up with the heat rejection. 
 
Interesting point, Ed. Perhaps the ideal cooling system design looses ground during the initial take-off and climb phase.  You'd take off on full power with temps low and back off on the throttle if you get to the max temp limit before reaching enough speed to cool the full load. Once you're up to speed, then you can cruise with minimum drag.
 
By the way, Monty, what are you building???
Regards,
John
