Most of these airplanes have piston engines with 2 to 5 times the
displacement of the Mazda 160 ci 13B Wankel yet Dave is competitive.

With a p-port, more streamlined intake manifold, max 2 rotor turbo power
will go up from about the current 250 HP to about 300 HP at the same
45 inches of HG boost. Of course bost levels could go much higher
as the Wankel block is very robust indeed.

In car drag racing these turbo engine will develop well over 700 HP however
that would take a change in gear ratio from the current 2.17:1 to
more than 3:1 so the engine can rev to its 10,000 or 11,000 RPM red line
without exceeding Mach 1 prop tip speed.

I suspect many of these turbo piston engines racing at Reno are now using
NOS so the sky is the limit there.

Perhaps the next step is a cleaner airframe and a 3 or 4 rotor.

The picture captions are largely self explanatory.
The guy standing on the left in the fourth picture name is Red and he was
Dr. Dave's teacher in anesthesiology as well as his pilot CFI instructor. He has a
Phd in oceanography as well.

As a result of the 229 MPH posted Dave has won the $1000 Everett Hatch memorial
prise for exceeding 220 MPH using a Wankel rotary engine in an air race.
A past winner was Tracy Crook at 210 MPH.

That depletes the fund and raises the bar to 250 MPH assuming we get
new donations. First we must beef up the RV tails to raise the VNE.
