Does anyone have data on conditions to cause detonation in a parallel valve IO-360 or angle head IO-360/390?
I’ll soon need to tell Thunderbolt what pistons to put into my new RV-10 IO-540. I’d like to have 9 to 1 to gain cruise efficiency, but assume the new 100UL will be too pricey to be limited to that one fuel. Looking options to run it on either 93UL or Swift 94UL by:
- Procedurally restricting takeoff manifold pressure
- Retarding timing
- Combination of the two
So far I have information on what people “think” is the way to do this. I’m hopeful this data will provide a firmer foundation.
