This part was especially interesting to me.Think about it."Double pass radiators require 16x more pressure to flow the same volume of coolant through them, as compared to a single pass radiator. Triple pass radiators require 64x more pressure to maintain the same volume. Automotive water pumps are a centrifugal design, not positive displacement, so with a double pass radiator, the pressure is doubled and flow is reduced by approximately 33%. Modern radiator designs, using wide/thin cross sections tubes, seldom benefit from multiple pass configurations. The decrease in flow caused by multiple passes offsets any benefits of a high-flow water pump."
Using the old 1 square inch per HP you have a rad capable of cooling 384 HP. Congratulations.
Honestly,I'm going to go single pass on the dez car.Gonna run distilled water ,PG coolant @20% and a single pass 18x36 rad layed pretty flat(NOT GOOD)but only place it will fit and look good while being pretty protected in a crash rollover with 2 16" Spal fans pulling IIRC(the highest cfm they make in a 16") 4800CFM total. Hope it cools 750 hp OK in the funky location. I'll try to snap a couple pics tomorrow of the styrofoam mockup. Still waiting for the rad to come.
if mine goes out i'm installing this one for the extra thrust http://www.speedwaymotors.com/Flex-a-lite-Model-160-Electric-Cooling-Fan,39992.html
I got the jet covered.................
