 Lynn, am I reading this right? You are running a 12A motor with
 carb in a 1993 and later tube frame car?

That is correct. In GT-3 we have the 12A and a carb with two 36MM venturies.
The same car with a 13B and a carb with 44MM venturies would run in GT-2, a
faster class. There is only one class for turbocharged cars in the SCCA,
(Sports Car Club of America), and that is called T-1 and T-2. This is sort of
a show room stock class for BMWs Corvettes Porsches and other people with too
much money. That is where the twin turbo RX-7 runs.

So they handicap you with 36 MM 1.4 inch diameter venturi for the 12A 
and 44 MM 1.73 inch diameter venturi for the 13B. I don't suppose
they allow peripheral ports either.

The two rotor version of the Le Mann engine with no such venturi limits and 
peripheral ports would put out 345 HP normally aspirated. 690 HP in four rotor form.
What are you getting out of your 12A in GT-3 and what are they getting in 
GT-2 out of the 13B's HP wise?
