Bolt On An Additional 200 HP For Your SRT8 392 HEMI Challenger

Despite the incredible amount of factory horsepower offered from Chrysler with these motors, it’s been a slow, but steady incline of aftermarket support. Now, ProCharger has stepped up to the plate, and is now offering the 2011-12 SRT8 392 Challenger owner an additional 200 HP in a nice bolt-on friendly package. 

Official Release:

ProCharger Announces SRT-8 392 Challenger Kits!

Accessible Technologies, Inc., manufacturer of ProCharger supercharger systems, is excited to announce Intercooled ProCharger Systems and Tuner Kits are now shipping for 2011-12 6.4L SRT-8 Challengers (and 5.7L Ram Tuner Kits).  This industry leading technology produces a gain of 170 RWHP with a conservative 7 psi.  For those wanting to purchase a tuner kit and have custom tuning performed by a local ProCharger dealer, the gain is nearly 200 RWHP with 8 psi.  In the very near future we will also roll out tuner kits and systems for 2011-12 5.7L Challengers, 2011-12 5.7L and 6.4L Chargers, as well as a complete system offering for the 2011-12 5.7L Dodge Ram Truck. 

ProCharger has had fitment on 392 HEMI Challengers since early 2011, but we’ve held off putting this system into volume production until a reliable, cost-effective solution was available for engine calibration. That solution is now available, and these latest ProCharger HEMI systems feature a Diablo handheld programmer.  

Being the first manufacturer to offer complete supercharger systems for 6.1 and 5.7 HEMI’s back in 2007, ProCharger continues industry and HEMI leadership with being first once again with offering a complete supercharger system for the 392.  To find out more about 392 ProCharger complete systems and kits, check out
