I'll start this out with a good video link on the subject: https://www.youtube.com/watch?v=h3bATVXMHQg
Our own testing on Les Kearney's RV-10 show similar gains in fuel economy as demonstrated here- about 8-10% at the same speed.
Background info on LOP:
Basic idea developed in WW2 to extend range.
Extensively used on radial powered airliners in the '50s and '60s, especially on the R3350 turbo compound engines. Was found to extend life of these engines which was a big deal. Proven in millions of flight hours here.
Approved by Continental and Cirrus.
Lots of good flight and dyno data supporting its use by the folks at GAMI, Mike Busch etc.
Still not accepted by many pilots and overhaul shops.
Let the discussion begin...
