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.
