Peter Stiles flew N27RM for the first time, and the neat matching helmet in the first flight picture is his. Enclosed are a few pictures, sorry about the loading time, you asked for them (GRIN). I have been in Redmond for the last two weeks, and noticed when I returned that there were a few posts about ram air in Legacys with IO-550-N's installed. I have the first (to my knowledge) installation, and have no performance data, since my time in the Legacy prior to last week was only in 199L, but here is the first solid observation on the new ram air scoop. As you can see from the picture (sorry I don't have an overhead shot, I didn't even think to take one of the installation before it was installed. You will see in picture #13 the ram side of the scoop, and just above the generator in picture #14, the filter for filtered air input. Lancair (Mark Mahnke) told me I could expect to get in the area of an additional inch of MAP at cruise. I left my notebook in Portland, so will try my best to get the numbers correct. 11,500', OAT -5C, 2400 RPM, full throttle (as I remember it, full throttle was 20.2" MAP) yielded 260 KNOTS TAS. That number I won't forget! I was impressed. The only speed mods to N27RM are fillets on the horizontal stabilizer to fair it into the fuselage a little, and our new wingtips (see picture). I checked the ground speed, since I didn't as yet have a feel for the accuracy of my airspeed indicator, and with 4 runs checking with GPS from Madras to Bend (two each way) the TAS checked out as accurate as I could compute it, considering that my big grin was using up all my face skin! So, I'm very happy with the scoop and filter. I will post another article on the wing tips, these are prototypes, and are kind of ugly since we used too thin of a material for the see through portion and need to have some thicker ones pulled from the mold so we can countersink the screws instead of these ugly ones.but..they are definitely an improvement over the original tips.
