That looks quite badass.I can understand why you might be having some cooling issues.The cooling stack is layed down directly over the engine.Did the electric fans have any effect?

Electric cooling fans would get my vote.

All h1's are that way, shouldn't affect it much. His issue is elsewhere

If you still have the plastic skirts between the wheel and frame ditch them. We use the factory oil cooler as a double pass for the trans, and use the stock D-Max oil cooler without issues. Since yours has atleast a 2" body lift, make sure the gap between the hood and rad/IC is closed like factory. If not the air just passes over the rad/IC and not forced through.
