3rd gear data
3rd gear G-tech data vs. changes Superformance 2040 with Roush 427R-095
The power values represented are G-tech HP. This should not be confused with any other method of testing HP. It's only a number of reference.
Just as wheel HP on a chassis dyno is lower than flywheel HP because of additional drive line loss, the G-tech HP is lower than chassis dyno due to additional resistance such as aero drag and road resistance, even amount of air in tires would have a factor. As speed increases aero drag as well as other rolling resistance increase. For example as an estimate @ 50 mph there is an equivalent of approximately -12 HP, @ 100 mph -90 HP, @ 130 mph right about -200 HP for the shape of the Cobra.

Chipped Flywheel
Proper starter alignment should fix this.

Chassis Dyno - Last Run 427 High Riser
Self built 427 SO, stock stroke, 429 ci., Dove aluminum High Riser heads, mildly ported, 10.5 : 1 CR, original holley 780 cfm LeMans carb, vacuum secondary, on an original single four BBL , dual plane, Hi-Riser intake. Chassis Dyno is at Performance Engineering, Hamilton, OH.
Carb jets changed, and timing adjusted by Performance Engineering. Picked up 80 ft-lbs torque and 60 hp by chassis dyno tuning.
With a 20% loss, estimated max flywheel torque is about 600, with about 570 flywheel HP at 5900 rpm's and still climbing.
The torque curve is pretty flat.

chassis dyno Roush 427R
Here is a chassis dyno of a Roush 427R crate engine, as installed in a Superformance. They have installed many of these 427R engines in cobra's, and this is the best output any of the 427R engines had made. They are rated by Roush at 550 HP and 535 torque at the flywheel. The engine was not run above 5800 rpm's where you would expect to see max HP, but the max torque is a good value.
I wanted to use this engine as a benchmark to compare my 427 SO engine to. Both cars running the same sidepipes.
