Pushing the G90 limits
I have run a few of these and never any serious problems and has been my #1 all around sport engine of choice. I have alway propped them appropriately. However I haven't read the ST manuals in a long while but I noticed the rpm ranging up to 16k. Anybody running one of these up in that area. I am considering installing one in that Phoenix F-20 and expecting average performance on a 12/7 prop.
However I may just for the prop this thing with an 11-something Apc and go for it.
