Craig,

My airplane cruised at 215 kts until I discovered that the static line was disconnected in the cockpit. Now that it is reconnected, my 7,500 ft max speed is 195 kts.

Oh and by the way, in the last Sun & Fun 100, in 1992, I Believe, Bill Harrelson came in first and I came in second. I navigated incorrectly and flew an extra 5 miles. Bill beat me by about 20 seconds. I like to say that I have the fastest 160 hp Lancair. In the 1993 Redmond race I came in first. Scott Krueger's IO-320 is 5 to 10 kts faster than mine because he has more that 160 hp.

You are either running at over 200 hp or your airspeed indicator needs to be corrected. No 160 hp Lancair can fly faster than 200 kts at altitude.
