Heather and Jim,
good point to seal all gaps thoroughly - I'll first focus on this. I've already
installed an aluminum sheet to press more air through the radiator. Only a very
low amount of air goes through a gap below the radiator to the 7-row (!) oil
cooler, which won't cause a lot of additional resistance. I've also noticed,
that I have a gap between the upper edge of the cooling duct and the lower
cowling
just below the spinner, which I also have to close....
I have some hope, that the Whirlwinds would also contribute to additional
cooling.
I think I'll let the Airmaster-dealer make a Quote for me.
I'll see if I can ad some photos later.
