Supercharged 1960 300 d Engine

Maximum performance is derived from large volumes of fuel ignited in the combustion chamber. Fuel needs oxygen to burn, the more fuel supplied, the more oxygen required. One of the limiting factors in a high performance engine is the volume of oxygen containing air that can be introduced into the combustion chamber. An efficient way to increase air volume is to use a supercharger to force air into the system. A supercharger is a turbine spinning at extremely highSupercharged 1960 Mercedes-Benz 300 d Engine rpm used to compress air and to force-feed the combustion chamber with adequate air to burn the supplied fuel.

Pictured here is a supercharged 1960 300 d engine. Air is force fed to this engine using a Vortec V2 centrifugal supercharger. At 5500 rpm, the engine turns a jackshaft at 14,500 rpm that in turn produces a supercharger impellor speed of 45,000 rpm, producing ten pounds of boost. The result is a 25% increase in horsepower.

High performance requires precise engine timing and fuel monitoring. To facilitate this, modern crank and camshaft sensors relay engine timing to a full sequential, laptop programmable, electronic fuel injection system, allowing each cylinder to be individually tuned.

Other engine modifications include a 9-blade clutch fan from a modern Mercedes-Benz. Ceramic coated intake and exhaust manifolds and a six rib serpentine belt with custom machined pulleys.
