Hey,
I bought a flex light 18", 6 blade fan meant for the mopar clutch fan system. A warning came with the fan which apparently has 4000rpm rev limit on it which wasn't mentioned on summit racing (http://www.summitracing.com/parts/FLX-5718/) when I bought it.
Is this because viscous fluid in the fan clutch has a step down effect on the rpm?
If so, what percentage of a step down is it (so I can work out the max rpm the engine can run at without risking shrapnel fan in the engine bay!)?
Cheers
