So far, so good. Performance is good. The Prince pulled harder out of the hole, but the Luga/NR is faster on the top end. I went from 200' takeoff to 250'. I can live with that. After the world of bullcrap is over, I'd like to try a pair of 79" blades in it to see how they perform.
For the record, ALL 2-stroke Detroits have a blower. These are not super-chargers they are blowers to move the air through the ports to the combustion chambers and evacuate exhaust gasses. Without the blower it would not run. They do not provide boost over standard atmospheric pressure. Later, more powerful engines added the turbo to gain boost over standard atmospheric pressure.
Great looking project, BTW. Have you ever tuned into the "Bus Greasemonkey" on YouTube? He's a traveling Detroit mechanic who only works on old GM busses. https://www.youtube.com/user/avonpicturethis
