I know this is slightly off the subject. But, do not gas engines have a displacement handicap against Rotary engines. In all other forms of racing a Rotary engine is regulated to twice the displacement of the standard Rotary engines size; i.e. a 12A Rotary engine has a displacement of 1116 cc and is adjusted to 2232 cc to be equal to a gas engine. Land Racing is the only form of motorsports that increases the rotary displacement three time its normal displacement; i.e. that same 12A Rotary engine would compete in class E (up to 4 liters) instead of at the bottom end of class F. Correct me if I am wrong on this?

I think they went by Mazda's advertised HP claims in their RX8, which was actually found to be far lower in real life, and Mazda had to buy many of them back from disappointed owners.
I'm kidding of course, but I do get a little frustrated at the Greenies who claim that a Wankel is a Green engine, and a way to lower fuel use. RIIGGGHHTT.
Specs are approximates:
2010 Corvette, 3200lb, 430HP, 26mpg highway.
2010 RX8, 3000lb, 238HP?, 22mpg highway.
The RX8 is both a smaller and lighter car, and I don't have to bother stating what a huge difference in performance there is. The Vette is a lowly 2v pushrod V8.
I believe the SCTA calculation is based on the true amount of air drawn in by each lobe of the Wankel. Some orgs take in consideration that Wankel power efficiency is only 2/3rd's that of a 4-stroke in real life, so the handicapping is going on in the other orgs.
