Hi guys,
I was doing some dyno work with Borla at their facility and we did a before and after test of the Stinger exhaust on my Cobra - which should be used as a magazine article in the future. All I can say is WOW! The car is stock other than a KB CAI.
I used the Autotap to make sure the engine conditions were consistent from run to run.
Engine coolant temp was 203 deg at the start of each run
Air intake temp 1 was 78 deg for each run
Air intake temp 2 was 126 - 128 deg at the start of each run. (after the intercooler)
All runs were SAE corrected. There was no additional correction factor added - this is true power at the axle - tested on a Dynapack Model 3000 with a sweep time of 12 seconds. The car was usually consistent within about 1 hp from run to run.
The battery was disconnected to reset the computer, and then follwed the same warm-up procedure to help it re-learn.
Overall, the car went from about 388-389HP to a best of 435HP (!) - and made 3 runs in a row that were all right there. If I hadn't run the test myself, I probably wouldn't have believed it.
I don't guarantee that everyone will see the same results I did, but it sure made a huge difference on my car.
