Also, I believe it is slightly incorrect to divide by the red line RPM. The time spent at a given RPM value depends on that specific RPM value itself. We don't know the exact RPM value but we know a range, therefore you should divide by the bottom or top range value. Or better still, divide by the center of the RPM range. This would bring, for instance, the last number you showed for the GT3 from 0.14 s to 0.13 s. Not a huge difference, but in the interest of science... 🙂

It is important to note that the calculation for the time the engine has been over redline is the MAXIMUM amount of time. If the engine was revved much more than redline then the amount of time would be lower, but the RPM's would have been higher which would put more strain on the Engine.

Perhaps I missed the explanation, but shouldn’t the denominator be higher than redline given these are reports of when the engine is going above that mark? The second one especially should be atleast 7250 instead, knowing that we are above 7250 rpm.

If you're not getting to redline then you aren't enjoying your Porsche. A Porsche is most fun running between 4,000 and 6,000. You can run 2nd and 3rd all day there or you can flog your car on a track and it'll keep coming back for more. Not concerned about the DME. Drive, enjoy, repeat.

Do these Porsches not have fuel shutoffs? I would have expected the computer to shut the fuell off long before these engines hit 11,000 rpm. Like, before the clutch is fully engaged during the downshift. No fuel = no ignition spark = no DME counter. Right?
