The W211 5.5 Kompressor engine makes great power from the factory. When you bought your AMG, punching the throttle put a big ear-to-ear smile on your face, but as time goes on that feeling fades away as you become used to the power. Bring back that feeling with an Alpha 5.5 Kompressor Tune & Crank Pulley Upgrade! This simple and safe modification will net you another 100HP!!
More Boost the Right Way
Many competitors use a solid pulley to raise boost levels. While this is a cost effective way of doing things it can come at a price to the owner. Non damper pulleys transfer unnecessary vibration through the engines rotating assembly and components. Over time this can cause premature wear, oil pump fatigue or failure as well as potential engine failure. We use a new OEM Mercedes-Benz crank pulley assembly and precisely machine it to accept our 6061-T6 aluminum outer ring. By doing it this way we are able to maintain the factory accessory pulley and harmonic damper.
Easy To Upgrade Pulley Size Down The Road
Being car guys we know often we crave more power as time goes on. With this pulley upgrade our engineering team made it easy for you to increase power levels in the future by making the pulley a 2 piece design. If you want more power you can easily upgrade from the standard 172mm to the 180mm pulley by changing just the outer ring of the unit, no need to buy a new assembly.
Not Your Typical Generic Tuning Solution
Most tunes available are generic, rebranded, solutions that come from one of a few sources. Typically these tunes are developed more by software engineers than seasoned race engine specialists. As an enthusiast why would you settle for the same run of the mill results? Our custom tune is perfected for your 5.5L Kompressor engine by our in house calibration specialists.
