I have been flying this system for 18 months and 150 hours, including a
Sun 100 and an AirVenture Cup race. I have not destroyed my engine with
detonation even though it has 10:1 pistons.

John,

 

Will you be in this year's cup race?  If so, you can look under my hood if I can look under yours.  I am now also running the LSE ignition.  Too bad your wheels won't fold up...........
