I actually had thought about that, but with the shroud, it would impede the air flow, I would think.  Although, if the inlet duct was the same size as the fan diameter, which is 15”, it would still be larger that the actual air inlet itself.  Perhaps that is an option.

Steve,

 

            Cooling fans work just as well on the front of the rad as they do on the back…

 

Just a thought..

Ed,

It is hard to beat $5 each.  Tapp wasn’t too bad at all on the radiator though.  The radiator itself was $375 plus shipping.  I just got back fro the airport.  I tore out the old evaporator cores and fiberglass plenum.  The new radiator is too big to fit the way Intended.  The actual radiator, as I found out, is actually 15.75 by 22.75.  Slightly larger than the dimensions I gave them, but even at 22” it wouldn’t go in as I intended to mount it.

I’m going to have to mount it more horizontal.  By relocating the fuel filters and fuel pumps, I can get about a 30 degree angle, and enough spacing to get a diffuser built that should do a good job of air distribution.  The bad news is that I won’t be able to put the cooling fan in as I planned for ground operation.  I’ll have to come up with a different plan for it.
