I was impressed with the Subaru when I first considered building a KR. About that time I acquired my mothers car which was a Subaru. From what I had heard the Soob had to rum at approximately 5000 RPM to develop its rated power and torque. I don't think I ever ran my Soob at 5000 RPM. I figured from monitoring the tach and speedometer that I would have to do 100 MPH to attain 5000 RPM. Then one day it quit suddenly from a broken timing belt. The timing belt was probably because of a lack of maintenance on my and my mother's part. If I remember correctly it had about 70,000 miles on it at the time, but I feel better with a geared timing of the Corvair. Also Gene Byrd's KR was Subaru powered and had a cruse speed of 135 MPH.

The numbers that he has quoted me are as follows: 1,850 fpm climb rate, 170 mph max level speed and 150 mph cruise. My KR-2s is almost ready to fly. It is equipped with an ej-22 with a Les Palmer built reduction unit and prop. Since my airplane is lighter than his, I am expecting even better performance. I will know soon, and I will let everyone know what numbers I come up with. Auto engine conversion vs certified aircraft power seems to be a hot topic in homebuilts these days. There is a lot to be said on both sides of the issue. Before one makes up his mind, I think it would be a good idea to read Richard Finch's Book on the topic. But, if you are using a VW or Corvair engine, you are actually in the auto conversion camp already. Even though the Subaru EJ-22 is heavier and there are engineering issues to be dealt with in order to achieve a workable engine, it is my opinion that it is a quantum leap over the VW or Corvair. The main reasons I feel this way are due to the increased reliability and wt to power ratio offered by EFI. I would be very interested in hearing any and all comments on this issue. ronev...@aol.com _______________________________________________ see KRnet list details at http://www.krnet.org/instructions.html
