MXA Hellcat Performance Packages

mXa high performance acceleration packages combine our research & development of the Hellcat platform with testing on our in house dyno, cruising around town and data from the track.  707 crankshaft HP is fun, but 800 to 1400 crankshaft HP is out of this world!  What type of mad person needs that much horsepower?  You do, why else would you be looking at this page?  So by this time you’re asking yourself how much horsepower do you need?  Well our packages are as simple as 1,2 or 3 or can be customized to your liking.  Horsepower and torque can be gained multiple ways on the Hellcat platform, but proper tuning and torque management is key in keeping this beast from destroying itself.

Vehicles are protected with plastic and fender covers, receive a 27-point inspection, and undergo a 2-person quality check. We do all dyno tuning on our in-house dyno, and test drive each vehicle at cold start, idle and cruising to ensure quality and performance. Throughout this process video and pictures will be taken. Upon vehicle pickup, customers receive a complete invoice of all work performed, as well as a dyno sheet with dyno Wheel Horsepower and Torque numbers. 



*All dyno numbers are relative to each specific vehicle. Every vehicle is different and will put out different numbers with the same parts.
