right, it was done with a g-meter device...which if properly set up is just as accurate if not moreso as the car is moving in actual conditions (airflow, temps, etc.) I'd like to see the raw data from his runs...the "whp" so to say, I know he scaled them by a % to approximate driveline loss so his plots show "Crank" hp. Looks to be well done IMO.

BTW I'm not ignoring the dyno plot issue, I've asked around and nobody has one...so I have nothing to post.
