    when I took one of my Hellcats to AFE power, we ran a series of dyno test before and after several modifications... However, before we started to wrench on it, we performed a dyno "out of the box." The Hellcat had 2,000 miles at the time of the dyno and had a tested dyno result of 757HP. Didn't know if that was a known fact... But I was able to confirm that rating with several confirmation dynos.

    Umm.... if that is 757 at the wheels that is something like ~890 at the crank.

    The Hellcat does not make that at the wheels, unless you have a 100-150 shot of nitrous on it.
    It makes rough 610-650 depending on dyno, gas, and gear. Oh, and mood.

    650 would still be north of 750, which is what I suspect it is actually shipping with

    SAE certified measured output - 714 HP @ 6200rpm / 652 TQ @ 4800rpm. This is prior to drivetrain loss to the wheels.

    The factory provides horsepower ratings to the crank and not the wheels... So it's 757 factory to the crank bro... Meaning that the factory underrated it by 50HP

    You did not have to. When you quote dyno numbers, they only come from one place. And that is at the wheels. One speculate driveline loss to guess crank HP or "Flywheel" hp.

    The HC is a 710-740 HP all day long (FWHP) depending on the octane, the weather, and the computer's whim.

    Only one person has put numbers on multiple drag strip runs to indicate anything more than 740 HP (flywheel), and that is Johnny Hellcat here running 93 octane.

    Dr. B, I thought the highest trap I saw was Johnny's at 127-128? That is where I received my "estimate" with sea level air & 93 octane.
