I think I remember Shiv from Vishnu saying that the cars that were driven hard and not "babied" useally put down higher numbers on the dyno.

I think that the car should be driven through the entire rpm range. It was explained to me that by allowing the engine to run hard in the upper rpm range it will force the piston to travel farther up the cylinder wall due to enertia. This is important because the piston ring is going to wear a groove in the cylinder wall ultimately creating a lip/edge where ever the ring was topping out. So lets say you babied your engine and never went above 3,000 rpm and the stroke of your piston never peaked higher than 4" (to make it easy). So later when you decide it is time to open her up the piston could potentially be traveling 4.2", but the piston ring is hitting that edge/lip that was created in the cylinder wall at 4" durring break-in, hence hindering your potential to make more power.

Hope that helps, or at least makes sense.

 

It is imprtant to get the engine up into the peak rpm range in order to seat the piston rings. You also need to make sure you continually vary the rpm range don't just cruise at 2,500rpm for 20 minuets straight, downshift, give it gas, just make sure you vary the speed of the engine. Other than that you just need to make sure you get your oil changed at 500mi, then at 1,000, then at 2,000 all with the standard recommended oil. Then start regular 3,000 mi oil changes with your choice of oil, I prefer mobil 1 synthetic.

Of course how hard you drive determines how often you should change your oil. If you drive like a bat out of hell often or track your car, then regular 2,500 mi oil changes may be needed.

 

I agree with everything posted with the exception of not raising the rpm limit above 3k rpm. I think that you should begin the procedure like he suggests, but instead of waiting for the 1,000 mile mark to pass before you start to gradually raise the engine speed do it from the beginning.
