This is from "Stratified Charge Rotary Engine Critical Technology
Ennoblement Volume I" Page 253

It is a chart comparing a 400 HP John Deere rotary with a PT6.
The PT6 weighs close to maybe 600 to 900 pounds.
Cost well over $100,000 dollars.
Fuel burn probably .6.

Fuel burn on the rotary .5.  17% better.

Rotary weight with gear box 250 pounds.
Add another 30 pounds for the cooling system.

I put in the TTC 2 rotor engine.
Imagine a Mazda 3 rotor with the same boost. :-)

Of course we are running Methanol so subtract a couple of hundred
to run on gasoline.

I would say well over $100,000. One was bought by my friend for his
Turbo Beaver, 4 years ago, a unit overhauled, which he bought
at auction for $230,000CDN.

Wow!!!

It never seizes to amaze me how dumb people are. Does it take a degree
in physics or mechanical engineering to see the potential of
the Wankel? Do they fully comprehend the importance of power
to weight ratio? Must the skies be full of Wankel powered airplanes
before they realize that they really work?

Are they hung up on 5 to 10% worse fuel burn?
That could go away with one additional invention.
