Check out this video of a radical hand-built, custom fabricated 1970 Challenger. It his powered by a 572 Hemi with a pro-charger, making an astounding 2,500 hp. That is 3X the power of a Demon! It was displayed at the SEMA show and is now making the show car cicuit. After this has been done, it will be sold for around $500,000. https://www.reddit.com/r/cars/comments/edk4u2/bagged_2500_hp_1970_dodge_challenger_named_havoc/
