If you want a REAL electric fan from the aftermarket, look at the Black Magic series fans from Flex A Lite. The ones in the upper CFM ranges AIN'T cheap, but they flat out move some air.
That’s good info for those in the market. :thumbsup:
I ended up using the short Hayden clutch, a modified 18” lovingly and carefully :preduced to a 17” (biggest diameter I can fit) MP 5-blade with my CVF pulleys (no under driven nonsense) with an Edelbrock Victor water pump knock-off. The name escapes me. No cooling issues at all. Happy camper.
