[QUOTE="RUNVS?, post: 16816389, member: 3198"] As for the claimed horsepower that Beechmont and Lebanon Ford use in their advertisements (725/675 with the Whipple | 650/600 with the Roush), I'm sure that's flywheel horsepower and torque measured at the crank, not at the wheels. Accounting for ~15% drivetrain loss, they'd have to pump out about 850 HP at the flywheel to get 725 at the wheels. Using the same metrics, 725 HP at the crank should translate to ~608 HP at the wheels. I've never put the truck on a dyno, or ran it at a drag strip.... and probably never will. I use my seat-of-the-pants meter and my RaceBox GPS accelerometer to gauge the performance. How the truck stacks up against the competition on the street offers up a pretty good clue as well. Since the truck was probably tuned by Beechmont Ford on a dyno, it would have been nice to get a printout of the pull. I just failed to ask for one. However, if I need to check on the engine diagnostics myself, I'll just plug the Tomahawk tuner into the OBDII port and live stream the data. So far, I haven't had to make any adjustments. :cool: There are multiple links all over the internet promoting these 725 horsepower F-150s. Here's one for Beechmont that went up in late 2020. My XL Sport was $44,802.69 delivered to my driveway. [URL]https://fordauthority.com/2020/12/lightning-inspired-725-hp-beechmont-ford-f-150-costs-just-50k-video/[/URL] [/QUOTE]
