yes 800hp gross not sae rated and SAE rating is not wheel HP. SAE rated takes into acound engine accesories etc etc but drivetrain loss.

to the wheels they are in the 620-660range depending on dyno and transmission. 0 stock hellcats have hit 700+ hp on the chasis dyno.


gross hp is engine total output right to a dyno.

SAE HP is net power as installed

wheel HP is power to the ground (dyno's vary quite a bit though)


this is why a 400hp car from today is way faster than a 400hp car from the 60's. net vs gross HP rating.
