While I was healing up from eye injury I got the chance to put the Demon on the dyno for final fuel mapping refinement. The race shop I use runs a Mustang Dyno, notorious for being stingy with torque numbers. At 5200 rpm (6.1 Hemi) I am at 452 HP at the tire and still well north of 400 on torque. I about peed down my leg listening to them wind her up. My idle is still a bit high as a result of a vacuum leak I need to chase down. But man she runs! Holy Smokes. Well pleased
