That's just ridiculous when people say that electric fans don't work.....the simple truth is that power is heat and the more you have the better the cooling system you need.......if I can have zero issues with a 571hp 415" and then same zero issues with a 976hp 434" with the same 2 core 1.25" tube Wizard radiator and a 16" Spal fan and others do have issues it's not the electric fan theory fault......you have a problem with your car period!!!!

Easy partner, remember your blood pressure.
All I am saying is that electric fan(s) did not work for me and no there were no other engine issues. My BBM 512 would get hot at slow speeds until I converted it to a 18 inch 7 blade Mopar fan set up, never got above 195 again even with the A/C on.
Many others members on FABO have had the same experience.
