Which Fan Is Better

I bought one of those flex fans and someone told me i should put the stock clutch fan back on because i lost some horse by changing the fan....what do you think?

I bolted on a flex fan when my clutch fan went out it made a some extra noise. I did notice a lose of horsepower so i ended up buying a new clutch fan and storing the flex fan. You win some you lose some.

The best thing to buy is an electric fan that way you arent driving it off your serp belt and letting it steal HP. The addition of an electric fan added 8-9 RWHP to my buddies 1990 Hatch 5.0 GT. That with underdrive pulleys and you are set, unless you buy a S/C..... but thats a whole other post!
