I have been thinking about this on the way to work this morning. I'd probably need to see a stock 930 graph for comparison. However, it is somewhat on-off once I get to the boost threshold, which I assume is a function of the turbocharger characteristics. I'd imagine a quicker spool turbo, like on a ricer, would have a much flatter curve and not have the same sharp slope as RPM increase. I haven't had a chance to analyze the data contained in the graphs, and there is still a lot of data on the dyno which we didn't print. I'll retrieve that next week. My concern at the moment is fuel delivery, or lack thereof, which appears to be the limiting factor in how much boost I can run. I think there are certain limitations with CIS which I am also contemplating (EFI HAS to be way more efficient).

So, if anyone has any other dyno charts, feel free to post them. It will be like a big lab experiment.
