    Curious if anyone knows exactly how the Hellcat is restricted to 500HP when that mode is chosen. Is it a wastegate on the supercharger limiting the boost? The supercharger whine seems to be much less noticable in this mode.

    Some others will jump but I believe it's changes that occur in the PCM. Basically it de-tunes the car.

    I know the brochures say the supercharger is clutched.

    Maybe the clutch stay disengaged?

    Is there any boost shown on the 500hp setting?

    It does make a huge difference. That's what my wife will have when she drives ours.
    Black key or drive mode stepped down to 500.
    No Donuts for her!

    Okay HC vets, maybe a stupid question, .... but coming home from the dealership after delivery I'll have the 2 red keys and the black key all in the car with me.

    Which (red or black) is controlling the HP of the car?
