RDP Motorsport’s latest offering, which trumps the Challenger’s SRT8’s 6.1L Hemi and its 425 horsepower with a stroked version displacing a classic 440 cubic inches. That block is topped with a duo of superchargers that offer an astounding 1,000 horsepower. Oh yeah, it’s also boosted with two nitrous kits. That’s enough grunt to catapult the portly Challenger down the 1/4 mile in the nines, and if that’s not fast enough for you, we suggest therapy.
Are those actually twin screw superchargers? or is it just two roots? It looks like two roots style superchargers to me, either way sick setup and a sick looking car, nine seconds is nine seconds and that is one sweet way to get there.
