The ‘R’ designation in the SF600R Challenger denotes a SpeedFactory hi-performance, normally-aspirated, bored, stroked and balanced 6.1L Hemi block, increasing the displacement to 426 cu. in. (7 liters).
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. Handling is improved with performance springs and sway bars as well as additional front and rear strut tower braces. The SF600R Challenger rides on premium Michelin Pilot Sport PS2 tires mounted on staggered 20” BBS Black Edition CH-R flow-formed wheels.

Pull up next to this Challenger at a light and you'll be in for a surprise. Under that bone stock exterior lies the heart of a beast - a very angry beast. Even if you pop the hood, you won't see any difference - the beast knows how to hide.

Happy customer Doug from Indiana sent us this note about his Stage 3 Supercharged Challenger:
“I’ve had the car up to 185 mph and it handles just like a dream. Having my car shipped to Atlanta was like sending one of my kids, I couldn’t wait to get it home. As soon as it was off the trailer it was time to put it to the test. As my neighbors watched I prepared them for a NASA take-off.
I stomped on the accelerator and all I could see was smoke from the tires burning off of the rims and my neighbors seemed to disappear in the smoke. I looked at Mark and said “that’s what it’s all about” with a smile from ear to ear.”
