I just watched my engine get dyno tested. It is a normally aspirated IO-550N EXP with 10:1 compression and magnetos. It made 325 hp at 2700 RPM. There is an engine builder in California that claims 370 hp. I have a question for those who have this engine: - Are you sure you are getting 370 hp? - Have you seen the dyno test? - Do the recent Reno race results support the claim? I have been lead to believe that the answers to the above questions are: no, no and no. Flame suit on, D. Brunner
