What is the best mechanical radiator fan to use? I currently run a steel mopar fixed 7 blade fan. It cools great, but wondering if i'm losing a lot of power at the dragstrip?

I have the 7 blade flex a lite, we both are giving up HP, but I have no choice, 512ci with A/C in Southeast Tx They say about 30 HP compared to an electric fan.

I run the Derale Rigid Race Fans 17318 on my 512. Cools very well.

We have run Sumit stainless flex fans for years.Had one on my Jeep and RamCharger that was daily drivers and plow trucks.Never a problem.One on my 440 in the 65 has been on over 20 years.It runs 180 even in the 90s.Never over heats.Ran one on my sons 62 300 and also have one on the 360 in his Express truck.Rocky
