Does anyone happen to know, ideally from a data sheet: 1) At what RPM does the turbo start spooling up? 2) What is the max effective RPM for the turbo - i.e. at what RPM is the turbo giving the most power? From my own experience of Copen ownership, it seems like 2000 is the start of the turbo spooling up. Likewise, it looks like the max effective RPM is about 4000 RPM.
