Interesting numbers for the baseline pull on the 2.7L. Does anyone else have baseline dyno numbers for a 2.7L? I had some mods done on my 2000 Boxster before I found a dyno, so I lack a baseline (really kicking myself on that one).

I have been assuming a 15% loss in the powertrain. I believe the numbers racertroy got, but a 17.8% loss seems high to me. Any ideas why there would be that much drivetrain loss?
