could be due to the rotary design, all rotary engines ive seen backfire on downshifts.

why does it spit fire you ask? my guess is that the flux capacitor is overloading the flexnard scale.... yup i bet thats it

1. Because the straight through design of the rotary. There is no valves to pass thus giving flames a straight shot out the exhaust. 2. Rotary's dump fuel in the chamber to help cool it so it creates a flame. Mine would only do it between shift above 6K, Never noticed it down shifting.

Running too rich perhaps.

Is your RX-8 stock or modded?
