The 6.1-liter Hemi has been bored to 7.0-liters creating 426 cubic-inches of naturally aspirated Hemi displacement.  The 426 ci motor uses an all-forged rotating assembly and features CNC ported aluminum heads with a host of new components.  The end result with all the goodies is a dyno-proven 600 horsepower on 91 octane fuel.  Other modifications finding their way on the SF600R Challenger include Corsa stainless steel cat-back exhaust system, Centerforce clutch, Getrag IRS with 1,000 horsepower half-shafts.  The suspension has been improved with performance springs, sway bars and front and rear strut tower braces.  Keeping all this horsepower on the pavement is a set of 20-inch BBS Black Edition CH-R flow-formed wheels with Michelin Pilot Sport PS2 tires.  Special badging, a serial numbered plaque and premium leather seats round out the feature list.

The 2010 SF600R Challenger can be purchased for $73,900 and is available now.

SpeedFactory, the leader in modern Mopar supercars, today announced the industry's first 6spd manual, 600 HP 'SF600R' Challenger, as part of their complete line of 2010 Mopar supercars.

This modern 426 powerplant has an all-forged rotating assembly and features CNC ported aluminum heads with new valves, guides, seals, Bee Hive springs and titanium retainers. A custom Comp hydraulic cam along with an 85mm throttle body works with a CNC machined stock manifold that is port matched with a blended plenum to produce a dyno-proven 595-605 HP on premium-grade 91 octane pump fuel.

Additional SpeedFactory performance modifications include a CARB- certified high volume air intake and Corsa stainless steel cat back exhaust system for better breathing. The increased power is managed with a Centerforce clutch and a Getrag IRS with 1000 HP half-shafts.
