Doug, I have always flown with An-16 bungs and 3/4 " ID hose (AN-16 also).  Tracy Crook flew with two 5/8" dia hose (parallel).  So in my opinion there is  no real advantage going with the 1 1/4" hose unless you are going to upgrade the bungs to 1 1/4 as well.

Subject: [FlyRotary] Radiator hose size...

I just received my Griffen radiator from Summit and was thinking about what size hose to use  with it.  Dennis Haverlah welded AN -20 bungs on his Griffen an I blieve is flying with 1 1/4 inch hose.  My engine which I bought from Tommy James flew with 3/4 inch hose and has AN-16 NPT bungs on the front housing for input / output hose hook up.  
 
So can I get adequate cooling with he original 3/4 hose set up, or will cooling in theory be improved by going with the bigger hose?   160-180 hp is all I ever will run in this airframe... 
 
Thanks for any input...
