Gentlemen and Ladies (I know of two building KR's) I did receive my EFS-3 and installed it. I used the exact airbox on the EFS-3 that I had on the EFS-2. My static rpm (cowl off) was 2750 with the EFS-2 and 3100 rpm (cowl off) with the EFS-3. I was ecstatic over the difference. With the cowl on, the EFS-2 gave me 2650 sucking warm air from inside. The EFS-3 dropped to 2950 sucking warm air inside the cowl. I made my first flight with the EFS-3 yesterday. The EFS-3, in flight, produced 3000 rpm. The EFS-2 would give me 2950 rpm in flight. Airspeed with both carbs was 135 mph. I was totally frustrated and wanted to throw my hands up and give up. The EFS-3 should be giving me much better performance so here are my next steps. Verify my distributor timing advance is giving me full advance. Install ram air. Using cool outside air and ramming it should give me more power. Re-design my airbox. So, if I were to leave everything like it is, I am no better off with the EFS-3. Hopefully I can get more power. As always, all comments and suggestions are welcome.
