That's a great article. It's an interesting perspective for sure. I personally want to get my engines into that high heat and pressure range, but my engines are also older V8 engines with looser clearances and aren't meant to last 500k miles. I use break-in specific oil, usually Driven BR30 or BR40. I crank the engine over on a stand for at least 30 seconds to get oil moving through the engine. I start it up and run it steady at 2000 rpm for 5 minutes to get it heated up. Then I load the dyno and make low rpm, half throttle sweeps from 2000-4000 rpm, never letting the rpm fall below 2000 rpm. I do this for just 4-5 pulls. At this point, I consider the break-in to be done. If everything is fine to this point, I go straight into wide open throttle, max rpm tuning. The only time the rpm is limited after that point is if the tuning is too far off at higher rpm to keep going and we need to creep up on it. It usually takes just 3-5 pulls to get the tune pretty close. Then the engine is shut off and taken off the dyno. The oil and filter are changed amd the torque is checked on all critical bolts and studs to ensure they are still all where they should be, lash is checked, and compression and leakdown is done. I consider it a fail if the leakdown is greater than 3%. Then the engine is sent to the customer or installed in the car. Many of these engines don't even see the dyno time. They do the 2000 rpm run-in on a stand, are put in the car, taken to the track, and beaten on immediately.
