The numbers below are for the piston = EVO vs. the piston IVP. I assumed that was what Ralf was talking about = but maybe I was wrong. Anyway, I don't see any de-rating of the IVP = on the Lancair website so people shouldn't be dinging Lancair about = that. =20 Colyn On Nov 4, 2011, at 3:40 PM, Colyn Case wrote: check the lancair website. I think the problem is at kitplanes. lancair shows the IVP at 330mph. but it will go 270 LOP. Caveat, the evolution max cruise speed is the 24gph ROP best power = number of 270 knots. The LOP number they give is 240 knots.

It just happened that I kept the December magazine from the previous two years since I liked this compressed comparison. One really interesting thing I found was that the Lancair IV changed its speed from 300 kts to 285 mph while the Evolution piston accelerated from 278 mph to 299 mph over the three years.=20 I am really amazed by these marketing engineers and their ability to beat the physics (e.g. designing an airplane with a bigger wing, bigger cabin and higher empty weight and make it even fly faster)..... May be someone can help me out since I don't have a degree in aircraft aerodynamics. -- For archives and unsub = http://mail.lancaironline.net:81/lists/lml/List.html -- For archives and unsub = http://mail.lancaironline.net:81/lists/lml/List.html
