Heres my break in procedure:
-No constant speeds
-No cruise control
-No WOT shifts (youre breaking in a clutch at the same time....)
-Slowly increase you revs as you put on the miles.
Im at 7xx miles on my FR-S right now and Im revving it up to ~6k rpm every now and then, just to build some heat in the motor. Im also giving it ~80% throttle here and threre to put some load on the engine.
I didnt rev past 4k rpm for the first 200 miles or so. But I would apply load to the engine, about 50% throttle. From ~200 miles up to 400, I would rev to 4500, 400-500miles was 5k, 5-600 was 5500rpm, and so on. Im slowly increasing the throttle input as the miles add up as well. By 1000miles, I should be bringing it to or at least near redline.
Thats my break in, not overly harsh nor "grandma-ish"
