Even amidst rising fuel prices, the Dodge Challenger has proven to be one of the most anticipated car to hit the market in years. Even though this brawny street brawler has just begun hitting the streets with its limited edition 2008 units, companies are scrambling to prepare for the aftermarket performance demand for the upcoming full scale production for the 2009 models. Unwilling to miss out on this action, Mopar Performance has unveiled the information about its Dodge Challenger Supercharger upgrade packages. Like they’ve done with many other aftermarket offerings, Mopar has gone to a third party to help develop and market these high performance Challenger components, and Speedfactory of Morrow, Georgia has been given the task of overseeing this project, with the results of that project to debut at the 2008 SEMA Show in Law Vegas, Nevada. Like almost all of the cars displayed at SEMA, the 2009 Speedfactory Supercharged Challenger will not have just a jump in performance, but also a full dress up to make sure that everyone notices this special, ultra high performance Challenger.


We all know by now that the Dodge Challenger SRT-8 is hitting the streets this summer, offering 425 horsepower, but for the 2009 model year an SE and RT trimline will join the SRT model, and Speedfactory has developed kits for both the RT and SRT units. The supercharged models will be the highest performing options, but Mopar will also be offering naturally aspirated options, with three “NA” choices joining the three supercharged options. These choices are broken up into stage 1, 2, and 3, and each of the stages adds a bit more power, along with interior and exterior styling additions. The NA kit begins with fairly simple items that many gearheads begin their modifications with and every kit includes a PCM tune to get the most out of the power-adding additions. As the kits get more intense, Speedfactory opens up your Hemi and improves the internal workings to make more power and improve the strength and durability of the engine. The Stage 3 kits are not fixed packages, but more of a “mix and match” worked out between the owner and the folks at Speedfactory to meet the owner’s needs and wants for their new Challenger. The Stage 1 and 2 kits can either be added to an already-owned vehicle, or a Speedfactory Challenger can be purchased from authorized dealerships.

Mopar / Speedfactory Stage and Package Options
Stage 1 Naturally Aspirated:
-Speedfactory Cold Air Intake
-Performance Exhaust from the catalytic converter back (cat-back exhaust)
-Speedfactory Stage 2 PCM Tuning
-Unique 20” Forged Wheels
-Speedfactory interior and exterior upgrades
- 3 year, 36,000 mile warranty applied to the motor along with the factory warranty
-Results: Speedfactory has stated that the 6.1L (SRT-8) Challenger with the Stage 1 NA kit can expect around 500 crank horsepower. That is an increase of around 17%, so similar results on the 5.7L Hemi (which starts at 370 hp in the R/T) would give the 5.7 around 432 horsepower, but that is completely speculative.
