Most people say its a 1000 mile bed in, 100 miles - oil and filter change, at 500 miles - oil and filter change and at 1000 miles oil and filter change and then you can reconnect the actuator and use boost.
Now according to that link its saying that the rings are 80% run in within the first 20 miles. It also states:
"The best method is to alternate between short bursts of hard acceleration and deceleration."
"Nowadays, the piston ring seal is really what the break in process is all about. Contrary to popular belief, piston rings don't seal the combustion pressure by spring tension. Ring tension is necessary only to "scrape" the oil to prevent it from entering the combustion chamber.
If you think about it, the ring exerts maybe 5-10 lbs of spring tension against the cylinder wall ...
How can such a small amount of spring tension seal against thousands of
PSI (Pounds Per Square Inch) of combustion pressure ??
Of course it can't.
How Do Rings Seal Against Tremendous Combustion Pressure ??
From the actual gas pressure itself !! It passes over the top of the ring, and gets behind it to force it outward against the cylinder wall. The problem is that new rings are far from perfect and they must be worn in quite a bit in order to completely seal all the way around the bore. If the gas pressure is strong enough during the engine's first miles of operation (open that throttle !!!), then the entire ring will wear into
the cylinder surface, to seal the combustion pressure as well as possible."
Seems a bit too extreme, but it does kind of make sense.
