Interesting, then I have another question!

What is a modern break in actually doing then? If the rings dont "wear into the cylinders" then what is a modern break in actually doing? Assuming all the Machine work is correct and true, then what is actually "breaking in" on the motor that manufacturers and even professional race engine builders still suggest a break in? Assuming that the rings will always turn inside (havent seen anything proving they do or don't) then all that the rings and cylinder walls are doing is smoothing themselves out. In that case, I only see a break in procedure lasting 10-15min of 2000rpm and then a few times under load and the motor should be 99percent "broken in". Hmm, time to do some more research for me.

(And yes, every motor I have/will ever build will get the rings staggered)
