Yesterday, the guy that does dynamic balancing of your engine/prop combo came down from Billings, Mt. for an airshow here in Sheridan. It was a good opportunity for me to finally do that balancing thing that I had always wanted to do but never seemed to get the opportunity. After all was said and done the engine was really, really smooth at all rpm's but the amazing thing was that I gained 50 rpm! He said he has seen this a number of times in 4 cylinder lycos. Don't know what that translates to in horsepower but its gotta be something. I gained it all the way from static to cruise.
One other thing for you guys that have been putting it off. My engine, when he started was .5inches/second out of balance. I guess that is in the upper range and I thought mine was rather smooth. When he finished, it was below .1 inches/sec. He said (and this could be just sales talk) that anything over that and the oil loses its ability to provide a film between the front crank and front main bearing. He said this should really make a difference in the longevity of the engine.
