Hi Paul
What is the latest on position and size for the radiators? I am thinking
of fitting the radiator under the cowl with the air entering above and
out the bottom.

Something like this seems to be the best cooling approach.
This is a P-port but it will work with an RX8 engine. The runners shown
here
are a bit long for a 2.85:1 gear box.

George has the pattern done for the bell housing/motor mount so he should
be able to ship you one shortly.

Hi again Paul

Did I get it right ? In at the top of the rad and out the bottom? Big as
possible. Adjustable louvres.

Is anybody flying with this configuration?

George down under.
Any pictures of your bell housing/motor mount or is it in the archives.
Archives WWW ?
Ian, also down under.

Yes.  In st the top and out at the bottom.
Dave Leonard and and Dave Atkins are flying something similar. Mike Hershfield
has been flying for years with the louvered flap. There are few others
in the works. K&M discovered by full scale test in WW II that if you put anything 
behind a rad it reduces the air flow through that rad. We confirmed this with a 
test rig on top of my van. The inlet duct on top of the rad protects the rad from 
radiated heat from the exhaust.

If you use a two pass rad the water plumbing is more direct and simpler.
