Date: Thu, 15 Jun 2006 22:14:33 -0400 X-Mailer: Apple Mail (2.750) After working for a week on all the details I did tonight my first run in NA mode. Prop is 3 blade IVO Magnum 68" electric set for take off (fine pitch) OAT 90F Right off the box without any tuning made 4900 static (2260 prop) I'm pleased, since the prop was ordered for my turbo setup. My turbo/ muffler does a very good job. The noise was very close to the one I had with the turbo. I basically gutted the turbo and left only the empty hot section on. Makes very compact and sturdy muffler, with exhaust pointed exactly where I want it without modifications. John Slade tells me this static RPM is sufficient for flight. I wander what other people think? I can trim the prop also and get a bit higher RPM. John is running 64" (same prop) with his turbo application. Buly Buly http://tinyurl.com/dcy36
