Even though last year's SEMA was ostensibly represented by the Camaro, it was Dodge Challenger City in the halls. To make sure the Challenger doesn't come up lame a year later, Speedfactory has taken a 2009 SRT8 Charger with a 6.1-liter Hemi aluminum block, bored that block out to 7.1-liters (440 cu. in.) and, among other tweaks, pasted a Vortech V3 centrifugal supercharger on top. The result is 700 horses when provided with 91 octane to drink.

To handle the boosted grunt Speedfactory has made a number of other modifications, including the installation of a Mopar Performance NAG 1 transmission and Getrag IRS with 1000 HP half-shafts. You can read get all the details in the release after the break and check out the Challenger in the high-res images below.

SpeedFactory's Signature interior package includes logo-embossed seat backs, matching door panel stripe with logo, custom floor mats, Mopar door sills and T-handle shifter. Visually, the exterior of the car has also been enhanced with a race-inspired, matte-finish, full carbon fiber hood and rear deck spoiler, as well as SpeedFactory Signature badging and graphics.

This car is part of SpeedFactory's research and development platform for its line of tuned, advanced engine, and supercharged modern muscle cars.
