Not mine but a nice compilation with a couple of FM's in the mix at 4:39 and 12:06.

The red one is a standard carbureted FM and the blue one is the factory Renesis protype now with a 6-port series II engine.

Don't pay much attention to the driver induced fuel pickup issue at turn 2. Note to self "Check the Fuel Level" before you come to grid.
