The S62 engine, known for its robust performance in the BMW M5 E39, has become a popular choice for tuning enthusiasts. One of the most effective ways to enhance the power output of this engine is through forced induction. In this article, we will compare two leading supercharger kits: VF Engineering and Vortech.
Understanding Forced Induction
Forced induction is a method of increasing an engine’s efficiency and power output by forcing more air into the combustion chamber. This process allows for more fuel to be burned, resulting in increased horsepower and torque. Superchargers, unlike turbochargers, are mechanically driven by the engine’s crankshaft, providing immediate power gains.
Overview of the S62 Engine
The S62 is a 4.0-liter V8 engine that was produced by BMW from 1998 to 2003. It is known for its high-revving nature and impressive power output, generating around 400 horsepower in its stock form. The engine features a DOHC design and utilizes individual throttle bodies for optimal performance.
Benefits of Supercharging the S62
Adding a supercharger to the S62 engine can yield significant performance improvements. Some benefits include:
- Increased Horsepower: Superchargers can easily add 100+ horsepower to the S62.
- Improved Torque: Enhanced low-end torque for better acceleration.
- Immediate Power Delivery: Unlike turbochargers, superchargers provide instant boost.
- Enhanced Throttle Response: Better engine responsiveness during acceleration.
VF Engineering Supercharger Kit
