Experimental Engine Option

Avweb published an article about engines that had a link I found very interesting. I wanted to share it for those who might be interested. Check out the IO-390. All the parts are factory Lycoming.

There is also an IO-580 built by Lycoming. Most of the unlimited aerobatic guys are flying behind them.

SB,
308 lbs. for the IO-390, which prop would you put on it to utilize the horsepower?
I don't think we'll see any of the major automotive manufacturers watching this in hopes to steal some cutting edge technology!
I do think the IO-360-X is very appealing as is for the cub. I would love to see it approved.

How much does an 0-360 weigh? How about an 0-320?

SB,
My decaying brain cells remember about 260lbs for 0-320 and 270 lbs for 0-360. The IO-360-X was 275 lbs.
It makes you wonder whether you should just put high compression NSF pistons in a 0-360. I would still go with the IO-360 -X if it were approved.

I have been watching this engine for years, will be interesting to see it come on the market.

The only drawback I see is water cooling.
