snip....it seems to settle in on 160 mph indicated. Sounds quick Larry given the empty weight and big wheels. My aircraft is comparable but the Corvair will only get me to about 130knots (150mph) TAS.Like you I'm after more!!
Did you convert IAS to TAS before comparing with your GPS? If not your results will vary dependent on altitude, QNH and temperature. Difference between TAS and GPS is essentially the wind component. It's been so bloody hot and low pressure in Aussie lately that at sea level I've been recording a density height of 4500feet....makes a big difference (say 15 knots) to TAS calcs and to engine performance.
