Last October, I flew the 358th hour on my RV-7, then removed the Subaru Firewall Forward. Since then, I've been working on installing a proper airplane engine. I started down a path with a carbureted Lycoming O-360, but switched direction and installed an ECi Titan IO-370 Stroker with Precision Silverhawk FI and dual P-Mags spinning a Hartzell BA prop. On Thursday, I pulled onto the runway and gave it the beans. That's when I discovered what the RV Grin is really about. Performance like my plane has never experienced!
Temps were a bit high for my liking, but that seems to be a consistent theme while breaking in a new engine. On the second flight today, CHTs were all down in the 380s and 390s, and oil temp was below 200 in cruise, so I think the rings are seating. I can't wait to get a few more hours into the break in so I can really start exploring the performance envelope. Then it's off to the paint shop!
