The BMW E46 M3 is a beloved model among car enthusiasts, known for its performance and iconic design. For those looking to take their E46 M3 to the next level, forced induction is a popular route to achieve over 600 horsepower. In this article, we will explore proven upgrades that can help you reach this impressive power level.
Understanding Forced Induction
Forced induction refers to the process of increasing the engine’s intake air volume, allowing for more fuel to be burned and thus generating more power. The two most common methods of forced induction are turbocharging and supercharging. Each has its unique benefits and considerations.
- Turbocharging: Uses exhaust gases to spin a turbine, compressing the intake air.
- Supercharging: Driven by a belt connected to the engine, providing immediate power boost.
