2010 SF600R Challenger 600HP by SpeedFactory
Firstly, the engineers increased the displacement of the standard 6.1-liter HEMI engine to a full 7.0-liters.
Aside from a higher volume air intake system paired to a stainless steel Corsa exhaust , SpeedFactory also used "a custom Comp hydraulic cam along with an 85mm throttle body 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," as a statement from SpeedFactory reads.
Furthermore, the engineers equipped the SF600R with a six-speed manual transmission, while also adding a Getrag IRS and Centerforce clutch, among others.
Inside, the S600R Challenger was fitted with features such as leather seats, leather door inserts, custom floormats and various badging elements. Rounding off the look are the 20-inch BBS wheels are wrapped in Michelin Pilot Sport PS2 tires.
"This car offers supercharged power in a normally-aspirated, 6spd manual package. It's a true enthusiast's car and it enables us to widen the appeal of SpeedFactory products to now include a 600HP vehicle for those enthusiasts who prefer a ‘normally-aspirated' powerplant. We offer the SF600R with either a 5spd automatic or the 6spd manual transmission," stated Mike Brillanti, President, SpeedFactory Cars.
The 2010 SF600R Challenger is priced at $73,900.
