The Road Dyno that our group has turned out to be a serious tool. It can be easily calibrated with a GPS to give speeds within .1mph. Several tests on my modified 9000 Aero recording 2nd gear runs starting from 1500rpm to redline(feul cutoff)6200rpm have poroduced some interresting data.
a-30 to 60 mph in under 2.9 seconds. accuracy down to one spark pulse <.01sec error. Compare to Latest road and track test on corvette, jag ect. just subtract the 0-30 from the0-60 times. My tests were done at 3500 ft altitude. Imagine how these other cars would be afected by the altitude change.
b-Rear wheel horsepower/torque (actual) not corrected at all for drivetrain losses,
altitude or any other factors of over 225hp with torque peak over 300lb/ft
c - over 200 wheel HP from slightly over 3000rpm to 5800rpm.
d-acceleration over .6g at the torque peak and above .45g over most of the power band.
THIS DATA IS NOT GUESESSES, AS THEY ARE DERIVED BY CLOCKING EVERY SPARK PULSE AND RELATING THEM TO THE CARS PERFORMANCE VIA DEFINABLE AND ACCURATELY MEASURABLE PARAMETERS.
