I said that I was really thinking of 'Big-pistons' especially when they have superchargers and turbochargers and such
Fully agree on that one.
With garretts each one is a lovely lady which you have to talk to to get the best out of. She can be a bitch some days and others an utter star.
MJ who has 4k hours and 9000 starts on garretts and best effort was a 60 ft blue flame out the back when I swung the props after pulling the red handle. Don't ask me how I managed it, I don't have a clue but was bloody impressed by the whoosh through the front and arse of it looking like concorde. ATC and AFS were less than impressed as was the ground crew that felt the waft of hot air over them or the bloke that was driving the baggage truck which it passed in front of.
Sitting in OAKN repeating 10% light up 40% oil light out please baby don't hang your a lovely lady. You don't have much choice in FBO.
