Hello everyone. I run a Mazda RX7 with a rotary engine and have found it very uncompetitive against the piston engines in the E class range where I run. Last season I sent in a rule change to fix this problem, it was passed both by the committee and by the board, but then revoked. ED=SV x 3 is what the rule book states, SV: swept volume, ED: equivalent displacement. The 13b is the engine I run, witch is 80Cid accordingly to Mazda, but with the formula it is 240Cid. I had it changed to ED=SV x 2, based on the thermodynamic cycle theory, before it was changed back.
