Stan....Thanks for the response. If I don't go with a Suby in the next one I will surely use a DTM Shroud. So far I've used a std flat-top shroud with flaps tack welded open and a 36hp with no flaps. The 36hp shroud cools my 2110 better by an average 18 F.
I have had in mind to build a horizontal shroud similar the old Corvair with the alternator separated and the like. First I thought I would use a VW fan but determined that it would turn the wrong way so that was out.The problem is that I have very limited knowledge of fans and it seems that they are pretty detailed, technically, to be able to find something that would fit my needs. Something that is already manufactured. There's gotta be something out there that would work. I have even thought of reversing the VW fan blades........Any comments Stan?..........Bruce
