Les Palmer has achieved good performance with his EJ-22. 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
