 |
|
I'm a long way from engine selection, but I've been hearing a lot of good commentary on the GM LS2 engine (used in the 2005 Corvette). The ones I have seen on aircraft have been derated to a maximum of 4500 RPM (redline is over 6500 RPM) limiting the HP to 300HP.
The engine new is less than $6k. Of course, all the mods will add up to closer to $20k altogether.
Opinions?

I agree in concept that the LS2 engine might make a good airplane engine, but in talking to someone who did some extensive research on this topic, when fitted with the PSRU, the weight and balance become unworkable on the RV-10. I haven't seen the numbers, though.
If you find a way to make this conversion work, please let us know!

It's about 50lbs more than the IO-540 once you load the coolant. Of course, that includes air conditioning. It's smaller than 540 also. We would need to load two batteries pretty far back to account for the difference in CG.
