Chrysler is said to be readying a new supercharger kit that could raise the horsepower of its 6.4L HEMI V8 to 570.

For those that say the horsepower wars are over, listen up. Chrysler is said to be readying a supercharger package for its LX-based SRT products that could raise horsepower to a tire-shredding 570 horsepower.

According to a Motor Authority source, Chrysler is putting the finishing touches on an Eaton-sourced supercharger package that will increase the horsepower of its new 6.4L HEMI V8 from 470 to somewhere between 540-570. That would put the Dodge Challenger on par with the Chevrolet Camaro ZL1 and Ford Mustang GT500, and would put the LX SRT sedans - the Dodge Charger and Chrysler 300 - in some pretty rarefied air.

The twin-screw supercharger kit will reportedly be offered as a factory part, but it's also possible that dealers could offer the kit as a retro-fit to cars currently rolling off the assembly line. No pricing has been leaked, and it doesn't appear as though the option will make it to the Jeep Grand Cherokee SRT8.

The kit is expected to launch late next year on 2013 model year cars. That launch date should coincide with Chrysler's introduction of a new eight-speed transmission for eight-cylinder applications, ensuring all 570 ponies are put to good use.
