Yes, it still looks like that.  I assume that if I use the whole cowl as a
pressure vessel that the augmenter will be the only way out.  One of the
options I was looking at was to modify the scoop and put the rads on the
floor of the scoop and exhaust it out the bottom like Perry did (no
augmenter). I see this on a lot of the drawings that you did for tractor
installations.  My concern is all of the the hot turbulent air being fed
into the prop. With an augmenter ejector it would be expelled close to the
hub.  I was also thinking about an augmenter on to of the engine as heat
rises it would not subject the whole cowl to heat.  That is why I asked
about the remote water pump.  Thanks for any help.

I see getting the exhaust pipes up and over the intake
manifold as a problem. How much room do you have in front of
the engine?

Paul,
There is 12" in front of the motor to the FW.  I was thinking of bringing
the intake tube out into the wing root area for the TB and stuff.  Or maybe
a P Port.
