Greg,

Very interesting and exciting!

A couple of questions:

How is the fuel efficiency compared to an IO-550?
What is the noise level compared to an IO-550?
What would be the total cost of converting from an IO-550 - including 
engine, all engine accessories, reduction gear, prop and belly scoop?
What will the new cowling look like?
What effect does this installation have on weight and balance?

D. Brunner
