HOLY COW!!!!
"IF" those numbers are correct, 635 HP and 591 TQ rear wheel numbers, that beast is putting out more than 707 HP and 650 TQ at the crank. The engineers at SRT did say that the engine does produce more than 800 HP months ago.
I need to see an actual dyno with a video camera and see the numbers up on the screen to be fully convinced. I like good hard proof. Not saying these are false or real numbers, just like to see hard proof to take away any doubt.
