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.

G-tech speed graph comparison.
All cars tested by Greg Schroeder in same location, same G-tech Competition meter, correct calibration with 12 inch rollout standing start stage. Representation has a slight variant of exact comparison due to different days of testing. For reference DA(density altitude) can be determined per date and time of testing per car by using weather history for Scottsdale, Arizona, Bell & 56st. http://www.wunderground.com/weatherstation/index.asp
