Mopar have just unveiled their new Dodge Challenger Drag Pak, featuring a host of upgrades that’s sure to take Factory Stock racing in the U.S to the next level.

The Challenger Drag Pak is a ready-to-race drag car developed by Mopar Performance, and while the new Challengers cannot be legally driven on public roads, they sure look like a blast to drive.

Under the bonnet there’s a choice of two Hemi V8s and Mopar reckons both are capable of slinging the Challenger down the quarter in the eight-second range. The cheaper $99,426 USD package features a Whipple supercharged 354ci iron block combo, while the atmo 427 cube motor runs an alloy block and will cost around ten grand more at $109,354 USD. Mopar haven’t revealed power or torque figures for either engine, but at a guess the answer is “lots”.

Both motors push power through a race-prepped 727 Torqueflite transmission, and the rear axle mounting points have been strengthened to cope with the extra grunt. The suspension and diff have also been revised with a Strange Engineering 9-inch, with an aluminium centre and 40-spline gun-drilled axles putting the power to the ground.

The front suspension now also features a Mopar K-member and revised suspension geometry, and both the front and rear suspension sports double adjustable shocks. Inside, the Challenger Drag Pak features a full roll cage with Sparco seats and five-point race harnesses, and the standard gauges have been replaced with a Racepak digital display. While the designers were applying the stickers (blue for supercharged, black for the atmo), the bonnet was also made easier to remove and trailer tie-down hooks added front and rear.

It’s got all the goodies required to compete in the NHRA Sportsman class, and Mopar are confident that the package will be competitive right off the bat. But Dodge isn’t alone in offering a race-ready dragster from the factory. Both Ford and Chevrolet also offer race-spec versions of their muscle coupes. Chevy sells the nine-second COPO Camaro with a range of LS motors including an atmo 427 and blown 350, while Ford revealed its factory-developed and street-legal 600hp-plus 2015 King Cobra Mustang at SEMA earlier this year which has run a 10.97 second quarter mile.
