Back in 2002, the German engineers who developed the Supercharged MCS engine published a detailed technical paper on the developments. Of course, the basic MCS is unchanged for the intervening 3 years, so the info is still perfectly valid. If you haven't seen it, a copy (in German, with all the figures) is available here

If you would like to see the text in English (but without the figures) go here.

For the English speakers, I strongly suggest you fetch both -- that way you have both text and illustrations .
