Let's say your car has a new clutch along with the new rebuilt engine.

You're supposed to drive hard and let the revs climb then drop over and over, but how the heck are you supposed to do that when you have a "new" clutch that you need to keep under 4k rpms while you're breaking that sucker in???



Driving it hard enough to set the rings and beating it excessively for the clutch are 2 different things.

That first 20 miles is the crucial point in setting the rings, going on and off boost steadily is not going to hurt a new clutch, as long as you're not slipping the clutch and launching it, I wouldn't worry about it.

Drive it hard, it's called a break in for a reason, the only thing seating the rings is cylinder pressure so don't baby it.
