As you can see on this dyno sheet much p= ower is available where most folks like to run aircraft Rotaries.

The ports you see in that picture are design= ed to operate best at 9,400 RPM, at 250HP, however that is a 12-A engine.

2292 CCs vice 2900 CCs= for a 13-B, so more power from a 13-B. So ports designed for best power at= say 5,500 RPM would have a shorter top (Closing Point) and a smaller bridg= e opening. I do not let any of the side seal ends to cross over the port so= side seal damage is not a factor. So very nearly stock service life minus = the wear you would expect from spending hours of operation at full throttle= . With synthetic 2 cycle oil in the fuel and in the sump I suspect (but do = not know) about 500 to 1,000 hours. A hot compression check or a hot

leakdown test will tell the= tail.........LEH

We don't need no stinking= turbos.....when we can have 250HP bridge ports......
