The Alpha 9 CLS63 and E63 AMG Performance Package turns your 4 door sedan into a supercar killer. A package delivering over 800HP on pump gas with 10 second quarter mile times offers plenty of performance to put almost any modern supercar in its place!

The Alpha 7 Package for the CLS63 AMG and E63 AMG has been a big hit with the public and major news outlets alike. There is always room for improvement however. To take power to the next level we needed a set of upgraded turbos for the M157 5.5L BiTurbo power plant. One option was upgrading the compressor wheel and calling it a turbo upgrade. We had higher horsepower goals in mind though. We chose to implement full turbo replacements from our trusted partner, Turbo by Garrett.  These new ball bearing turbochargers make more power throughout the entire rev-range and provide instant boost response.  When you choose Alpha you make NO compromises.

The Mercedes-Benz 5.5L BiTurbo Alpha 9 Package

For over a year, we’ve had our Alpha 9 Biturbo Upgrade available to customers and shops looking for more power but it was not fully supported by the components necessary to truly make it a full Alpha 9 package. After an thorough design and development process, we’ve completed all the systems necessary to support a full Alpha 9 CLS63 and E63 AMG Package. In addition, a solid Alpha ECU tune to maximize power while retaining drivability and the luxury you’ve come to expect from your Mercedes-Benz.  Under normal operating conditions you’d never even know that 800+ horsepower was there.
