Excessive power is just enough, right? If you abide by that rule of thumb, perhaps you’d be interested in 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.
This outrageous pony car was recently unveiled at the PRI Show in Florida and is definitely a bit overkill for most people’s needs. So, while the Australian company will be happy to replicate this powertrain combination for you for a price, it’s good to know that RDP will work with you to design pretty much whatever you need on a custom basis. source
