Question is, did we believe it? In a word...NO. Were we surprised? Yes. Could it be a fluke? Could be. Could be ideal weather conditions, could be ??? Following this run, the first thing we checked was calibration. It was on the money. Then we put a FF AC Cobra on the Dyno, that had known Dyno numbers from another MD Dyno in Florida that the customer had purchased and transported in. He wanted to verify his numbers and Dyno sheet he received when he purchased the car, and as he put it, wanted to make sure he had been "told the truth about the power output".
425 HP and 437 ft/lbs in Florida. 420 HP and 436 ft/lbs on ours.
What does all this tell us? We are not sure except to say we knew it made 110 HP with the exhaust plugged. 33.7 psi of back pressure. We installed new plugs, wires, exhaust and raised the rev limiter and installed a tune. Those are the numbers it spit out.
One other comment. Last year we did a 69 BB Chevelle. A 90 HP gain. Did our customer believe it? NO. That was, until he hit the track. He previous best ever was a 12.80. His new ET? 11.90.
