Re: 5 blade fan vs.772 fan blade

Gotta believe that the 772 fan and the fan clutch sucks less horsepower than the five bladed solid fan. Just hearing the noise from the five blade version is enough to make me draw that conclusion. Can't say which one cools better but that probably depends on a lot of other things, like how radical is the engine, how much timing advance, and what fan shroud you are using.
