Hello guys. Just starting a thread to include all the Alpha ABI (Adrien Bertien Influenced) engines soon to be available from Team Orion. We were very happy at Nitro Challenge with the .24 five port in truggy, and the .21 three port in buggy. The .24 is a nice blend of power, driveability, and fuel mileage. Anyhow, we'll post in here about experiences with the engines. The 3 port we used at Nitro Challenge has been the club engine now, and I tell you, it just gets better every day we run it. These engines are going to have some serious durability, I can assure you. Just keep your air cleaner fresh, and they'll run a LONG time. Next stop Silver State with the same two engines.
