SpeedFactory, a top-tier modern muscle car builder, will introduce the first modern supercharged, all-aluminum, 440 Hemi-powered Challenger at the upcoming SEMA Show in Las Vegas, Nevada, Nov 3-6, 2009.
The SpeedFactory prepared 2009 SRT8 Challenger is powered by a bored and stroked 6.1L Hemi Mopar aluminum block, increasing the displacement to 440 cu. in. (7.2 liters). It includes CNC ported Mopar aluminum heads and a completely forged rotating assembly. A Vortech V3 centrifugal supercharger boosts the output of this reliable, modern Mopar power plant to 700HP on premium-grade 91 octane pump fuel.
SpeedFactory performance modifications include Mopar Performance NAG 1 transmission, Mopar Performance fuel rails, Moroso coolant tank and oil pan, Getrag IRS with 1000 HP half-shafts, Corsa stainless steel cat back exhaust system, performance springs, sway bars, and additional strut tower braces, 15” Brembo 6 piston front disc brakes and Bridgestone Potenza tires mounted on 20” BBS Black Edition CH-R flow-formed wheels.
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.
The SpeedFactory Challenger will be part of the MOPAR display from Tuesday, Nov 3rd thru Friday, Nov 6th at the SEMA Show.

On November 1, 2008, Speedfactory’s R&D Charger ran a quarter mile in 10.354 seconds, with a trap speed of 137.39 mph at Silver Dollar Raceway in Reynolds, Georgia. According to records kept by the LXForums.com moderators, Speedfactory beat all previous quarter mile times set by actual production LX/LC-platform cars — modern Dodge Chargers, Challengers, Magnums and Chrysler 300Cs. Speedfactory driver Eddie Rosa originally broke the record the night before, continuing to improve throughout the weekend.

With help from tuning partner Injected Engineering, the Speedfactory R&D (Research and Development) Charger is powered by a 426 HEMI stroker motor with a Vortech centrifugal style V-7 YSi-trim supercharger and an air-to-air charge cooler. As the Speedfactory R&D Charger develops over 925 HP, numerous systems were upgraded: 355 gears, a return-style fuel system and 1000HP half shafts. The car retains the stock transmission, brakes, suspension, and interior, weighing approximately 4200 lbs.
“We’re very excited by this achievement, as we have worked for a number of months to unleash the potential of this Charger. There’s still more we can do, and a good chance we can run even faster times,” said Mark Brucks, General Manager, Speedfactory. “All of us at Speedfactory, and our partners, are motorheads and fans of these cars as well as businessmen. This is what we live for, building speed and automotive dream cars.”
“The Vortech V-7 YSi-trim supercharger supports up to 1200HP with 78% efficiency,” states Gil Cormaci, Director, Sales and Marketing for Vortech Engineering. “We are very pleased with our association with Speedfactory, Landmark Dodge and Injected Engineering. The application of our YSi-trim compressor to this HEMI Charger was done with the highest expertise resulting in this impressive time and speed.”
The record-breaking runs excited Injected Engineering’s Ryan Wall: “Working with Speedfactory has allowed us to take the LX/LC vehicles to a new level. Our tuning expertise and Speedfactory’s resources have created the perfect partnership for record-braking performance. The Speedfactory R&D Charger is proof that our skills at tuning will bring customers the very best performance that a Dodge/Chrysler vehicle has to offer.”

Speedfactory is exhibiting a supercharged Challenger in the Vortech/Paxton booth at the SEMA show in Las Vegas, November 4-7, 2008 (booth #23053). This Speedfactory Challenger drew attention in the spring of 2008 as the first supercharged Challenger of the modern era. Tuned with assistance from Injected Engineering, it features a Vortech supercharger developing 560 HP on 6.5 PSI boost.
