The 300 SRT8 is Chrysler’s hot-rod version of the 300 luxury sedan. Since the 300 SRT8 shares many LX/LC platform elements with the Charger and Challenger SRT8 models, our packages are a perfect fit for any 300C or 300 SRT8 models.
This Stage 3 Supercharged 300 SRT8 has the Vortech V3 supercharger, coil over suspension, larger sway bars, 355 gears with the new Powertrax differential, long tube headers, six piston 15″ front and 4 piston 14″ rear brakes (drilled and slotted).

This is what dream cars used to be: all attitude, big damn engine, no recyclable canola bean upholstery. You know, back in the good old bad old days when a 560-horsepower, 4,000-pound, V8-powered rear-wheel-drive muscle car made you the envy of your friends, not the destroyer of Mother Nature.
The 2008 Speedfactory Challenger is gorgeous. Lowered over those blinding wheels, it looks the way a Challenger should look — nasty, evil and ready to commit multiple felonies.
With the Nittos, the 0-60 time dropped to just 3.8 seconds (an incredible 3.4 seconds with a foot of rollout like on a drag strip) and the quarter-mile blew by in 11.8 seconds at 119.8 mph. That’s exotic-car territory — right there with the Corvette Z06, Dodge Viper SRT-10 and Ford GT . And none of those machines are anywhere near as big or heavy as the Speedfactory Challenger.
Thanks to PowerTV/Street Legal TV for covering the Speedfactory Challenger at SEMA 2008 in the Vortech booth. This 2008 SRT8 Challenger features a Stage 1 Supercharge package with a Vortech V3 Supercharger, JBA catback exhaust and Speedfactory tuning.

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.
Our R+D Charger “Pumpkinstein” goes under the knife again, this time for a massive supercharger upgrade from Vortech. Our friends at Injected Engineering were on hand to help out. Click the video to see (and HEAR) the blower in action.
