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.
