KLEEMANN, one of the world's preeminent Mercedes-Benz tuning houses, recently announced the newest addition to their impeccable Kompressor range: a new supercharger system for the M273 V8 engine (i.e., 450 and 500/550 models).
Like their Kompressor system for the outgoing V8 engine range (M113), the new design integrates the inlet manifold, intercooler and Kompressor into a cohesive unit, resulting in a compact design that ensures factory-like fit looks and quality. A low boost pressure of just 0.30 - 0.70 bar ensures the system is safe and provides outstanding long-term durability for the engine, all while increasing power output of the 500/550 variant to 475 horsepower and maximum torque to 625 Nm (90 percent of which is available at 2,000 rpm). Fitted with KLEEMANN high flow exhaust headers and a stainless steel exhaust system, power output can be increased to an even more impressive 505 horsepower and a maximum torque of 660 Nm - enough to satsify all but the most insatiable power whores among you.
If you're interested, you can learn more about the new KLEEMANN Kompressor for the Mercedes M273 V8 in the official press release below, or visit KLEEMANN's website for the complete details of all the Danish tuning genius' numerous Mercedes offerings.

OFFICIAL PRESS RELEASE
New KLEEMANN Kompressor system for Mercedes-Benz V8 engines (M273)
Fifteen years of experience has turned KLEEMANN into the world market leader in Kompressor (Supercharger) technology for Mercedes-Benz engines. Now KLEEMANN introduces a new system developed for the M273 V8 engine range fitted in the current 450 and 500/550 model ranges.
Like the Kompressor system for the outgoing V8 engine range (M113) the new design integrates the inlet manifold, intercooler and Kompressor in one integral unit. A compact design that ensures factory-like fit looks and quality.
KLEEMANN introduces the EMS (KLEEMANN Engine Management System)
Cutting edge engine management technology and sporty engine characteristics. The anti-clockwise rotating Roots type Kompressor is characterized by its unique ability to develop plenty of power at low boost pressure and this type of supercharger has proved its reliability and efficiency for many years. The new electronically controlled fuel injection and management system KLEEMANN EMS is on the other hand a technological break through.
The fuel injection and management system allows boost pressure to vary from 0,3 bar to 0,70 bar as the engine rotates up the rev scale. The electronically controlled, varying boost pressure ensures progressive and sporty engine characteristics known from naturally aspirated high performance engines. Increase in rpm results increase in increased power output all the way to up to the rev limiter. Furthermore the system ensures an effect curve without any bumps or valleys.
The EMS reduces boost pressure thus power output a fraction of a second before gearshifts to ensure smooth and gentle shifts.
Punch from idle - Flat torque curve remains intact
Like the earlier generations of KLEEMANN Kompressor solutions the new system still ensures plenty of torque from low revs thus a car fitted with the new system will have plenty of punch from rev levels just above idle. 90% of torque is present at 2000 rpm.
Safe, durable, reliable
The low boost pressure of just 0,30 - 0,70 bar makes the system safe and provides long-term durability for the engine. To further improve the safety aspect the EMS features a safety mode constantly monitoring the fuel - boost pressure ratio ensuring that the engine cannot run lean thus suffer damage to the engine. In other words the boost pressure and amount of fuel injected to the engine will always comply.
Even if the car is driven in an area of high altitude (less oxygen, low pressure) and down to sea level boost pressure and fuel supply adjusts automatically to protect the engine from running lean.
