We definitely had a blast in installing the Weistec Stage 2 Supercharger into the heart of this w212 2010 Mercedes AMG. The power of this motor and supercharger install is just purely insane! This Weistec upgrade gives gains of +221hp and +219 tq, taking this monster to 672hp and 662lbs.tq of straight power, no lag! Check out their dyno graph below.
Weistec’s Stage 2 Supercharger System is specifically designed for vehicles with high flow exhaust systems, and utilizes the ultra-efficient Weistec direct drive belt system. Proper ECU remapping and supercharger drive ratios have been modified to work in conjunction.

Our conclusion:
The kit was well developed and was pretty much a direct bolt-on. It came with very detailed and extensive instructions with quick technical support response times. The Cypher handheld tuner made remote tuning from Weistec simple and does not require us to ship the ECU back and forth avoiding risks of damage/lost in transit or extra down time.
There were some issues and hurdles we had to overcome such as a compact engine space for hose/plumbing routing, slight customization for coolant reservoir bracket mounting, tight fitment for air/oil separator and minor adjustments needed to be made to power steering reservoir to prevent rubbing against sensors on the engine block. Like all other mods out there in the market, we know nothing fits perfect and will need some adjustments, kind of a given. All-in-all, for a project this size, the amount of “custom work” needed is less than anticipated.
