Thread: Electric or belt driven fan?

Tweet

it not hard to cool 500hp they never make 500 at idle i used both but still like the belt they work if the belt is on the pulley .if the electric fans die you may have more work and money to get back running .low speed may not be to bad with a open engine bay i sold a bbc 548 soild roller 14.8 cr that did make 700+hp EZ in 28 ford with a very small alum rad and one big electric fan never ran hot at idle and was driven on the street i had the same engine in my gto that did run a bit hot so alot has to do with air getting in and out of the engine bay water speed running thru the rad has alot to do with keeping something cool so do not over look it

Sometimes alignment is an issue. If you look at Don's picture above, a belt driven fan could be an issue here.....

Belt driven is usually more reliable and moves air better, but if you have limited space, electric may be your only choice. In some cars you might need a water pump riser to get the belt driven fan centrally located on the radiator. I would probably go with a Cooling Components unit with a shroud.
