Interesting indeed! Great pictures!

When I compare their dyno results with the results I obtained with a G-Tech Pro run they seem to make some sense of my seemingly low results.

Lot's of power lost through the Quattro drive train for sure. The static dyno obviously doesn't factor in drag or the unsprung weight of the tire/wheel combo. Both of these factors rob even more power.

My G-Tech run showed a peak HP of 318 @ 5977 rpm and peak torque of 279 ft-lbs at the same rpm. I'm not sure about the validity of the torque curve from the G-Tech as it very slowly went up all the way to 5977 rpm. The curve was fairly flat as expected but didn't drop off dramatically at 5600 rpm as it seemingly should have.

Some other data from the run: :idea:

60 ft 2.125 seconds
330 ft 5.538 seconds
1/8 mile 8.412 seconds @ 80.47 mph

0-30 mph 2.215 sec.
0-40 mph 2.923 sec.
0-50 mph 3.856 sec.
0-60 mph 4.856 sec.
0-70 mph 5.949 sec.
0-80 mph 7.361 sec

30-50 mph 1.642 sec.
40-60 mph 1.933 sec.
50-70 mph 2.093 sec.
60-80 mph 2.505 sec.


No passengers - weight estimated at 4200 lbs w/ driver and normal vehicle contents.

OAT 50 F/ 10 C

Am i reading it correctly? The 340 HP that it puts down sounds about right. But the 404lb/ft seems awfully high!

It says on the graph that it's fly wheel torque but for the life of me I can't figure out how they came up with "fly wheel" torque with the dyno connected to the spindles!

If it IS flywheel torque it's believable but I'm with you....seems awfully high if it's at the wheels.
