This is a true cross-flow radiator which channels the water from side to
side multiple times ensuring a substantially longer cooling time in the
radiator and pulling even more heat out of the cooling system.
Three main attributes for this radiator are:
Reduced cooling system operating temperature. We have consistently
seen 20-30 degrees cooler temperatures running this new radiator vs
a 54mm Koyo radiator.
Reduced intake system air temperatures. During controlled dyno tests,
we have seen 15-20 degree drops on intake air temps.
Reduced weight off the nose of the car. Compared to the Koyo, this
new radiator weighs approx. 2.5lbs less when fully filled.
The simple facts are that if you keep the coolant temps below 190
degrees, you are going to make more power. Also, if the intake air
temp is cooler, you will also make more power.
