I'm concerned about temps when taxiing and waiting on the ramp.  I've
looked at electric fans for the radiator but was wondering if I couldn't
just bolt a regular radiator fan onto the front of the engine drive
pulley and position my radiator in front of it. There may be enough room
between the engine and the firewall for that to work.

Anyone know of a good reason NOT to do that?

Thanx,

I do Joe. The rad needs  a space behind it at least 50% of it's linear
dimension. If the rad is 20 inches wide the space from the firewall
to the back of the rad core needs to be ten inches or greater. The other problem with
that is the rotary cruises at 5000 RPM so the fan will be sucking down
HP and therefore increasing the fuel burn slightly.
