just did some Road Dyno runs!MORE!
things works great- very consistent between runs!!
these numbers are according to graph which takes the median power of the neighboring plots--
peak torque 421 lb/ft@3500rpm
peak HP 343 @ 5100rpm
these numbers are according to graph which maps power at RPM--
peak torque 436 lb/ft@3530rpm
peak HP 353 @ 5740rpm
whats awesome is the HP with the stage 3(AWE downpipes/exhaust/chip/intake) stays stable to redline after the HP peak where it would usually start tapering off!

no its a road dyno measures power very similar to the way it was measured at UPRD!
provides great graphs!! heres a link!
item similar to this unit is used widely by rally/touring car teams in the field when an actual dyno is not present!<ul><li><a href="http://www.charm.net/~mchaney/homedyno/dynokit.htm">http://www.charm.net/~mchaney/homedyno/dynokit.htm</a</li></ul>

you're confusing this with a GTECH! more!
this isnt an accelerometer activated by inertia. it uses the gear ratio/tire size and engine rpm to determine speed-then it measures vehicle weight to determine power, also has correction factors for weather..and it starts from a rolling start in 2nd or 3rd gear! i will be testing a stock S4 tommorrow for a baseline!

This looks OK for comparative runs but not absolute values
There are way too many variables to make absolute comparisons: grade of road, wind speed and direction, frontal area, drag coef., etc.
Basically they are performing an analysis of a speed/time curve with allowances for drag. I'm not knocking it, it looks like a fun thing to play with, just be careful when comparing these numbers to either manufacturer's data or inertial dyno tests.
I'd be interested to see results on a Tip cause that's what I have and we haven't found a way to dyno these either.
