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...
