With that being said, nearly every dyno I have ever used uses SAE corrected numbers, with a smoothing of five. That is the best way to compare dyno to dyno IMO.

But, bottom line is the more shops that dyno these cars the better. The more information we have the better!
I have never been anything but Honest.

We have way too much data to back up what we measure to think otherwise.

The only reason a smoothing algorithm exists is because they use spark as an RPM signal which is extremely noisy signal.

This is the single biggest Error in data acquisition.

The Superflow uses the Laser beam sensor that reads as special reflective tape we install on the crankshaft harmonic damper.

No smoothing needed.

We record data at 100 times a second and get 26-28 pages of data with over 48 sensors being monitored on every pull, all though we don't use all of them all the time.

You should note this Superflow Chassis dyno is a 65K laboratory grade system, where others are in the 20-30k range No comparison.
