I was told by several that you should not exceed 40% boost or 5k until 200 miles, and then not exceed 60% boost until 500 miles. From that point on there is nothing to be concerned about. If you redline in the break in period and there is a problem even if it was caused by a defected part (how else would it have been) then Porsche has the right to deny warranty. All new cars are delivered with specific break-in guidelines from the factory and to be safe they should be followed regardless of any ones opinion. I have yet to hear of a failure on a new Turbo, so the choice is yours.

I know the old Turbo's were bench tested for several hundred miles before manufacturing began, I do not know if that is still the case today.

 

The only break in time Ive experinced was when girlfreinds doctor said to me was :Easy on the Implants for 4/6 weeks !

Gee-Bee

 

I red-lined mine a couple of times under 500 mi with no ill effects. Rest easy.

 

my dealer said the exact same thing. Keep it cool for first 1000, Porsche says 2k as CYA measure.

good luck.
