It's manufactured by Precision (the Silver Hawk unit) or if the customer requests, it could be Airflow Performance. There are a few IO-580's that use the Lycoming LFC unit. It was designed and built at our facility.

What fuel injection system are you using now on the IO-360M1B. I had a Bendix RSA-5 on my last engine but I had the FM-200 on my Rocket engine. Are you using the FM-200 on the horz induction nowdays or still using the RSA-5. I'm getting close on having to decide which direction I want to go. Thanks. Aden Rich.
