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 boost 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.

 Dave, Amazing accomplishment. Congratulations.

 Paul, re: cleaner airframe suggestion . . . Anyone working on a either a
 Formula 1 or biplane powered rotary?

 Cheers, JL


 Formula 1 requires an O-200. I don't know about biplane. I have not heard
 anything. Come to think of it a Formula 1 airframe might qualify for the
 sports
 class if it was a kit. The Sports rule used to require 2 place but I don't
 know if that is still true.

 Bob Mears should be pretty close to first flight on his 3-rotor
Supermarine
Spitfire.  That ought to shake up the Sports class at Reno.

What scale is the Spitfire?
