For a blast around the industrial park as payment, the Westech crew was kind enough to read out our rear-wheel horsepower on its SuperFlow chassis dyno when we dropped by. These are real-world numbers too, with the car warmed up from an hour and a half freeway drive, no icing of the intake, humid-but cool-weather, the works. Further-more, we're printing the first run where the dyno operator shut off early at 6,400 rpm to ensure not over-revving the engine. Subsequent attempts showed the power peak at 6,800 rpm, but the engine was heat soaked from back-to-back running, so we're showing the abbreviated first test here because it had the best numbers. Be assured there would have been a 600 hp here had the test gone to 6,800 rpm. The engine pulls to 7,000 rpm with a vengeance, so it's eager stuff all the way up, too.
For the record, Ford says its testing yielded 601 rwhp, which it estimates is 690 hp and 620 lb-ft of torque at the flywheel. Sounds accurate to us.
