I am having the disappointing experience of having my cylinders replaced on a 900 hr Aerosport Power engine at 900 hrs.(Lycoming clone IO-540)
It was originally built with 9.5:1 ECI Titan cylinders. It is now in the shop getting brand new Millenium cylinders with the standard 8.7:1 comp ratio. The engine shop called me today and asked if I wanted to put in 9.5:1 pistons again, but I was wondering if the increased compression was the reason the ECIs were toast at 900hrs.
I would love to hear everyone’s opinions on the pro and con of increasing compression. The engine has 1 standard Mag timed to 20, and a light speed ignition module set at Aerosport when it was built.
