It was a good weekend running in Georgia, the SpeedFactory Charger R&D race car with driver Eddie Rosa achieved a time of 9.45 seconds at 145 mph in the quarter mile:

Let’s recap. The crew at SpeedFactory Cars is here to build fast cars for daily street use. Out of that necessity the Orange Charger Research and Development car was born, aptly called Pumpkin-stein. It started life as a 5.7 Hemi Police Charger; Mark, Eddie and Mike had the bright idea stuff in a 426 Hemi and then teamed up with Vortech Superchargers (and other partners) to build/test new parts and develop packages for street use.

The car has been campaigned by SpeedFactory since June 2008. The car was a full interior stock drivetrain drag/street car running 10.29’s with a roll cage. As we all know the New Hemi community is growing and evolving everyday, and thanks to the bar set by Chris (Hemi~C) we had to change the game a little.

We didn’t want to add another power adder, and stuck with the Vortech YSi Centrifigual Supercharger with the same 14lb boost levels and 426 engine setup. We called a few of our partners, put our heads down and set forth to step into the 9’s. Not wanting to add any more power, we did what would come next – put the “Whale” on a diet. Previous fighting weight for the Charger was 4224lbs (with driver Eddie Rosa).

We started with the interior, losing all the usual suspects-seats, carpet, and headliner. Then we took it to the extreme. We scraped out all of the interior sound deadener and seam sealer, leaving the driver’s seat, cage and the original glass all around.

After all of the hard work, we went with a full cage and certification, which brings us to today, Dec. 12, 2009:

This weight is with driver Eddie Rosa included.

Mark and Eddie pulled up to the track (South Georgia Motorsports Park in Valgosta, GA) at about 10:45am. After tech they finished up some lose ends in the car and finally got to the lanes for the first run at about 11:30am. Everything goes fine during the burnout and staging the car.  Since everything is fresh Eddie decided to take it easy, leaving off idle and just running it. As soon as the light turned green Eddie laid into it and the car made it to the 60 foot mark and hit the tranny limiter. D’OH!

Next run was an hour later 12:30pm.  Knowing they had to get at least one full run in, Eddie was going to short shift second to get it past 1st gear and possibly blow through the limiter again. This burnout was longer than the first and the track prep was first-rate. Eddie pulled up to the lights and left off idle again, this time short shifting to 2nd at 5000 rpm, got past that point and then let it shift at 6700. Little did Eddie and Mark know this easy pass was a 9.64s at 144 mph with a 1.44s 60 foot time. Good enough, but of course there is more there.

Third and last pass. Same as the second, only to have track prep much stickier than before. It was like CRAZY GLUE! Second car out after prep was done in the right lane. This time the car hit the tranny limiter during the burnout, Eddie restarted her and redid the burnout. Lights come down and this is the result:

Needless to say Eddie didn’t leave the line. The car still has plenty left in it, and we will continue testing in the coming months – with stronger parts! The Charger may be have been on a quick weight loss plan, but it still has the stock drivetrain and electronics. We are using the stock engine location, engine mounts, sub frames front and rear, even the stock rear end. The OEM electronics are all still intact and we are using Diablo Sport Predator to flash the PCM. All in the effort to apply what we learn on the track – to lay down on the street!

Here’s a video of the final result:

The SpeedFactory 426 Charger came in runner-up to Hemi~C’s Magnum.

Recently SpeedFactory attended Mopars at the Strip and displayed our 600HP supercharged SpeedFactory Challenger – the first modern Challenger to be supercharged. Next door to us was a supercharged Challenger built by Classic Design Concepts.

The inevitable occurred – and Rob Wolf, editor of Mopar Collector’s Guide, did a “Pinks” style start for the grudge match on the 1/4 mile drag strip at Las Vegas Speedway. SpeedFactory driver Eddie Rosa emerged victorious with a 1/4 time of 12.374 seconds at 112.66 mph, beating the CDC car by 4/10 of a second.

The SpeedFactory Challenger has the Stage 3 supercharger package, featuring a Vortech Supercharger at 6.5 lbs boost, Hotchkis handling package, Magnaflow catback exhaust, and SpeedFactory Signature package. Installed options include Richmond 3.55 gears and Boze “Tach” style forged wheels. Everything else on the car is stock 2008 Dodge Challenger SRT8. As shown in the video, the Challenger was on street tires. On drags, the SpeedFactory Challenger runs in the 11’s.

Thanks to our partners at Vortech Superchargers, Magnaflow Performance Exhaust, Richmond Gear and Boze Forged Wheels.

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.
