My break-in is far enough to get it onto the trailer, then off the trailer and to staging at the track!

For street gears, I always recommend about two heat cycles of coming up to full temperature, then cooling all theway down. After that, put 'er to the wood!

When I worked at Dana in the engineering lab, we'd do about a 20-minute break in on the dyno, change the fluid, then begin the endurance tests.
