Getting rid of the stock clutch fan, but keeping the belt driven water pump dropped my ET a tenth on a high 11 sec combo.
Going to an electric water pump over a belt driven pump (electric fan already installed) dropped the ET another tenth on a mid 10 sec combo.
These tests were all done w/ 440 engines in my cuda.
