I tested with Fred years ago right after I won my first Q500 Nats. We took that same plane with a 8.8 x 8.75 prop and put it in a big long dive. If I remember correctly it only went 187mph. My FAI in Phx was not too good, we were kind off trying some different timing stuff and not really set up like we flew it at the trials. I got kind of put on the spot out there to fly it at lunch.

Fred took his FAI and put it in a huge dive and it went 245mph and then the engine blew up. So to say the least, I wasn't too interested in diving my FAI and waiting for the rod to pop...
