Today I took my RV-6, powered by a 2.6L equivalent rotary engine, back up into the sky after its last re-build.
Sure was nice to get back into the air. Putting on the high compression 9.7 rotors, along with mild street porting and fixing any poor compression that I previously had, seems to have given me about 500 rpm for a given manifold pressure without any apparent rise in the heat load. I also now have ceramic coating on my manifold, turbine housing, and exhaust pipe. I believe this is helping temps a noticeable amount.
I kept the MAP under 29 today, which I will do for a while to let things break in. At 7000', 28" MAP, I was seeing about 6000 RPM and 150 KIAS. Ground speed up around 180 kts. Max oil temp was 150 and max coolant temp was 190. But is was a nice cool day.
Just when I thought everything was going great WHAM!. MAP suddenly drops to 17" for no reason.... There goes my last hope for a turbo I figure... I wonder when the tower is going to note the smoke coming out of my exhaust....
I land and taxi back without incident, no smoke..
