No 22mm dmx...

But I was reviewing some of the original test motor files for the first dmx that was built, and by dyno run #350, we were in the high 160s, to low 170s. The Shearer pipe that we made work was about 600rpmrpm lower peak than the dm. The dmx was also an 18mm,, and made over 100ftlbs of torque.
