Rep Power: 807

If 470 horsepower is fun, 570 raging stallions can be positively evil. Rumor has it that Chrysler thinks so too, and the automaker plans to unveil an optional tier of SRT vehicles with upgraded powerplants. Later in the year, the Dodge Charger SRT8 and Chrysler 300 SRT8 will reportedly be available with an Eaton-sourced supercharger that will up output to somewhere in the 540-570-horsepower range.

The option (which could possibly come in kit form to be installed at the dealer) will be offered on 2013 model year cars, and, if the rumour holds true, it comes with another upgraded feature to help meter out the extra go-fast energy. Chrysler will fit the four door sports cars with an eight-speed automatic transmission. We sure hope this all pans out.

Currently, this super extra only applies to the SRT vehicles riding on the LX platform. That means the Jeep Grand Cherokee SRT8 isn't slated to get the upgrade. The Dodge Challenger rides on a modified LX platform known as the LC, but rumour has it the power boost will be available for that model as well.
