[FlyRotary] Re: Apex Slot Wear/ Grinding for 3mm Seals
  Yes I agree.
  I  took a guy that road races rotaries for a ride around MT Saint Helens that involved a 45 minute climb at full throttle at 6500 rpm, it made him cringe and he asked do you ever back out of the throttle, I replied yes when I want to land.
 At the end of the trip he said that he couldn't belive how I beat the crap out of the rotary compared to race cars.

Ok, so grooves don't wear in your application (car racing) with proper lubrication and air filtering.

What HP range would you estimate your engines spend 90% of their time in?

I was unaware of the hardening process if any. I have only seen 5 or 6 rotors with worn grooves in 30 years of looking.
