Even though last year's SEMA was ostensibly represented by the Camaro, it was Dodge Challenger City in the halls. To make sure the Challenger doesn't come up lame a year later, Speedfactory has taken a 2009 SRT8 Charger with a 6.1-liter Hemi aluminum block, bored that block out to 7.1-liters (440 cu. in.) and, among other tweaks, pasted a Vortech V3 centrifugal supercharger on top. The result is 700 horses when provided with 91 octane to drink.
To handle the boosted grunt Speedfactory has made a number of other modifications, including the installation of a Mopar Performance NAG 1 transmission and Getrag IRS with 1000 HP half-shafts. You can read get all the details in the release after the break and check out the Challenger in the high-res images below.

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 R Compound 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 on display at the MOPAR Booth, #43127 , from Tuesday, Nov 3rd thru Friday, Nov 6th at the SEMA Show.

I believe Motor Trend recently performed a tuner muscle test in which the assertion was made that the 7.2 (which is what Speedfactory wanted to send, but was unable to complete in time) could take 200-300 lbs off the front end.

The car is beautiful, but I'd be surprised if the 0-60 improves much over a stock SRT8 using street tires. It might be worth it for the sound alone though...

The car is not beautiful, IMHO.

Nice, but at what price? Dodge needs to address the factory car as Camaro is the real hp deal and Mustang power is coming and it is a better handling package. Still a great looking car though. Needs Jenny Craig.

Hell it's almost worth it to be able to say "I've got a 440 Hemi Challenger" and prove to anyone who says you're BS'ing them that you're telling the truth.

If they started using aluminum blocks from the factory I'd trade my 08 in, in a heartbeat.

I remember this car from the Motor Trend test.
Pulled off a 0-60 in 4.1 and it wasnt the 700hp version that was promised either.

If this is the same car that Motortrend tested, which it appears to be ... company making same claims about power ... it only makes around 450 hp at the rear wheel!!! More than 150 less than the company claims!!
What a joke of a tuner company .. I hope they go bankrupt very soon. At least when Hennessey lies about ratings, they are always low ratings.

Try reading the article there guy. It clearly states that Speedfactory was unwittingly delivered a stock 6.1 Hemi rather than the MOPAR performance aluminum 440 hemi and installed it unknown at the last minute. Even with this significant disadvantage the Speedfactory Challenger put up a good fight.

Last time I checked most of the 440's I've seen going into LX's and Challengers were 7.3L, best friend has a Arrington 440 in his Charger and 426 in his challenger.
