Of course you don't show much wear at 30-50 miles.

As far as honda guys expecting build their engines once a year, that is pretty interesting. Our one car here has gone two full seasons now, same build, still making 110psi and running over 860whp. I'm currently building three more engines for other cars to match that cars performance.

well just as an update, we just finished the 2011 season, so the engine has 50+ hours on it now, it runs fine, oil consumption is ok, but HP is way down. we're missing about 10-15 hp, and when you're only making 120, that is a lot! compression numbers are still ok

That is exactly the case. R&D is very expensive and in our Rotary market, there isn't much for return. Not many people are going to be willing to do such R&D for the passion of our beloved engine.
