There are lots of ways to increase water flow as well as air flow thru a 
radiator, and many do work. Thermostats with bypass holes apparently do help- 
some owners say the Stewart thermostats with bypass holes work well. But 
there is no single magic cure IMHO. No matter what we do, the Pantera radiator 
is 16% smaller in surface area than an equivalent-power Corvette radiator 
(16" x 28" vs 19" x 28"), and increasing core thickness is a 
diminishing-return approach. Our 10 feet of space (5 ft ea way) between waterpump and 
radiator also increases our pumping losses over a front-mount engine. Cheers- J
