Paul,

On the RX7 Turbo list, this was posted--a rave review for Paul Yaw:

Hello, all.

When I visited my buddy Paul Yaw at YawPower in Tucson, AZ, last week I
saw an engine that he built for an airplane. Really cool. Turbo 13B
rotary. Paul dynoed it on an engine stand at 280hp @ 6psi of boost. It
had a custom intake manifold that Paul had made to fit into the tight
cowl of the airplane. He had also fabricated a really trick exhaust
manifold. His work is beautiful.

Yo Paul Y how about some pictures of this stuff.
We will see it sooner or later at an airshow someplace :-)

Jeff is a friend that I worked for years ago when he was in the plastic
molding business.  Maybe I should start paying him a salesmans
comission!  I appreciate the fact that you posted it, as I am sure you
were just trying to be helpful, but the dyno numbers that Jeff quoted
include a naturally aspirated atmospheric correction factor which does
not directly apply to blown engines.  The real numbers are 6.4 psi, and
probably more like 265 hp.  I do appreciate your help, but I feel kind
of weird seeing this posted on this list.  It is still an experiment
until it is successful in the plane.  I took pictures but I haven't
developed them yet.  After I get them back I will have them scanned and
send them along.  Thanks BCGARDNER

You always have the opportunity to clear things up on here.

I can't wait to hear how it flys. I am sure everything will
be OK Paul as long as he does the cooling right. Not to worry.
Hopefully he is knowledgeable on cooling or is on this list
and asks for help. It is fine to have 265 HP but the cooling 
must be that much better as well.
