Great that you could find a 4 wheel dyno - just wish you had made a baseline run BEFORE the SC to be able to compare. Not sure if a 4 wheel dyno has the same 15-20% drive train loss as others or not but would be the best way of measuring what we are putting to the ground. We only have a 2 wheel dyno here but at the track I have lower ETs in 2WD than in 4.
Comparing different Dyno runs on different machines with different sized tires will be difficult. DynoJet is THE standard for measuring HP and TQ AT the wheels where it counts. The DynaPak units measure at the wheel hub and IMO are less valid as they are not testing the vehicle as it sits when on the street. With that disclaimer, it would still be nice to see others scans.
