Hey,
I'm selling a plane and the engine STC says the engine is a 285HP (2,700rpm @ 32.5") TSIO-520-McC from a 235HP O-470. It's not turbo'd and it's not fuel injected, I've checked. The data plate, stc, and logs match.
It was explained to me that the engine really is a TSIO-520 (modified to an -McC), only with the turbo and injection system removed. Since it was born a TSIO, it has to remain a TSIO.
Does this make sense and can it legally be called a 285HP engine if the STC says it is. Common HP output for this type of PPonk mod is 265-275HP.
