I am presently running a dual 11" spall fan that include a housing and relief one way flappers to exhaust air at freeway speeds with a griffin radiator. for my 327/300hp motor. fans rarely come on in the 100 degree So. Calif. heat, runs cool and when fans are on it will cycle off in about 1 min. They have run longer on over 100 degree day going up the montains. The other plus is that at slow to idle speeds in traffic they are moving a lot of air where the engine driven fan would be at a disadvantage. Ed ke6bnl
