For clarification though, about prism: Is the BSFC of .37 for the NA engine? And does prism measure and tune the peak ICP?

Finally, do you know anyone who has a rig for measuring crankshaft torque in flight?
Several thousands have taken the seminar and the only comments we get are that it was well worth the time and expense. We'd love to have you join us. The next class is in Colorado Springs, August 9 & 10.

As far as PRISM is concerned, the answers to your questions above are yes, and yes.

Crankshaft torque is usually measured in flight at the geared accessory case on the nose of the engine where there is a reduction gear for the prop. I am unaware of any such device for the engine you are flying to be used in flight. GAMI can do it on the engine test stand.
