Yes, the EVO2 5 ports have both ABC and AAC, I am currently running the AAC version in my FW05R, I have run about 3/4 gallon on it and the engine still feel tight at TDC when cold. My last AAC still feel tight after 4-5 races (with average runtime of at least 90 mins per race), Temperature after 45 mins main is about 120-130 deg.
