What engine does the plane have?
It’s a Lycoming IO-320-C1A. It’s a bit of an odd engine. It is set up for turbo charging and has a rear facing sump. The turbocharging setup gives it some more metal in the top of the cylinders which should make it more robust for the tortures of aerobatic flight. The rear facing sump is going to have to go. There is just not enough room for it. I’ll get another sump with a forward facing fuel injection servo mount.
