heat cycling

I was told rings don't bed in to Nikasil bores?

That is the same for F1 cars, they have to be heated up before they start and then they also have a very sophisticated clutch that makes sure that it does not stall as that would also trash the engine (I do not have all the facts, but i saw a tv programme where the presenter took about an hour to get out of the pits because he couldn't get the clutch action right)

Yes, there seem to be similar technical backgrounds. Me too have seen a F1 report about the clutches they use and that they are allegedly looking a bit like motorcycle clutches with multiple friction plates. But I have never seen one to be honest.

Here's some food for thought.

Why do we believe that the piston and liner would "wear" to itself in the first hour of operation, but not in the following 100 hours?

I honestly don't know.

Yes, was told the same.

What is harder.. the nikasil or the ring? Throwing two parts together there will be some break in occurring initially. and then just normal wear.
