Andrew,
That radiator looks like my first install
attempt except I fed it with a duct that came in on the lower left side instead
of underneath.
I doubt foil will solve your blistering
paint problem. That exhaust is hot! I have a muffler that is over
15MM from the cowl and with foil on the cowl the paint still blisters.

Must admit, all info re
cooling exit came from Peter Garrison, I really like people that think outside
the square rather than accepting "conventional".
If the photo below attaches, it shows the engine being setup a couple
of years ago, wedge duct can be seen on radiator, divergent duct is not on the
plane but goes under the engine mount, exhaust is all fabricated on farm,
manifold is piece of 150x50 mm oval cattle rail 3mm thick with 3 50x25 mm RHS
stubs welded to exhaust flange, pipe angles were deliberate to reflect as much
sound back into engine as possible, but not restrict flow, seems to work so
far. no muffler needed. stainless heat shield now wraps around manifold but not
pipe, its this area which is blistering paint so need to stick some foil to
inside cowl.
Intake now has small filter attached directly to TB for simplicity.

Looks like a really nice design. The cooling exits look a bit like
Peter Garrison's Melmoth; I think he had good luck with the design. The
'turbine' exhaust exit does look cool. :-) Did you include a muffler, or did
you just turn the stock exhaust manifold exit out the side? How are you
protecting the cowl from melting near the pipe? Looking forward to seeing
engine installation pics. Keep 'em coming (or just put them on a photo sharing
site).
