Having 470 horsepower under the bonnet means you’re going to move with some gusto but when there’s 570 rabid ponies up front, things can get wild.

Chrysler knows the difference and is planning to step things up a notch with a new top tier of SRT vehicles with upgraded powerplants. If recent rumours prove true later this year, the Dodge Charger SRT8 and Chrysler 300 SRT8 will be made available with an Eaton-sourced supercharger. This blower will boost the output of these machines to somewhere around 540-570-horsepower.

The supercharger option may be a dealer install job and will be offered on 2013 model year cars. What’s more Chrysler may fit its new eight-speed auto transmission to its four-door sports cars next year.

At this stage it’s believed that the supercharger will only be applied to Chrysler’s SRT vehicles riding on the LX platform. This means the Jeep Grand Cherokee SRT8 won’t be eligible for the upgrade. The Dodge Challenger should get the supercharger option, while the Charger SRT8 and the Chrysler 300 SRT8 will definitely be force-fed if required.
