The way I understand things, the only way to get more power out of a given displacement is to increase cylinder pressure (or at least average cylinder pressure).

I also have heard that engineers build about 67% extra strength into the parts that the stock parts are expected to see.

So when I see Hondas, DSM's, Nissans, Supras, or Mustangs claiming 400-500 HP with stock bottom ends, I wonder how the rods , pistons etc. are able to withstand this for very long?

Anyone have any ideas?
