The BMW M4 Competition is a high-performance vehicle that has captured the attention of automotive enthusiasts around the world. With its sleek design and powerful engine, it serves as a perfect platform for those looking to push the boundaries of performance. In this article, we will explore how to build a 700+ horsepower M4 Competition through high-end forced induction and supporting modifications.
Understanding Forced Induction
Forced induction is a method of increasing an engine’s 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. The two most common types of forced induction are turbocharging and supercharging.
Turbocharging vs. Supercharging
Both turbochargers and superchargers have their pros and cons. Understanding these differences is crucial for selecting the right system for your M4 Competition.
- Turbocharging: Utilizes exhaust gases to spin a turbine, which forces air into the engine. This method is generally more efficient and can produce higher horsepower.
- Supercharging: Driven by a belt connected to the engine, superchargers provide immediate power but can be less efficient compared to turbochargers.
Selecting the Right Forced Induction System
Choosing the right forced induction system depends on your specific goals and driving style. For a 700+ horsepower build, a high-performance turbocharger or supercharger kit is essential. Here are some popular options:
- Turbo Kits: Brands like Pure Turbo and VTT offer kits specifically designed for the M4 Competition, providing significant power gains.
- Supercharger Kits: Companies such as ESS Tuning and VF Engineering provide supercharger kits that can easily push the M4 beyond 700 horsepower.
Supporting Modifications
To ensure that your M4 Competition can handle the increased power from forced induction, several supporting modifications are necessary. These modifications will enhance the overall performance and reliability of your vehicle.
Upgraded Fuel System
With increased horsepower comes the need for more fuel. Upgrading the fuel system is vital to support the additional power. Consider the following:
- Fuel Injectors: High-flow fuel injectors are essential to ensure adequate fuel delivery.
- Fuel Pump: An upgraded fuel pump will provide the necessary pressure and volume for high-performance applications.
Enhanced Cooling System
Increased power output generates more heat, making an enhanced cooling system a necessity. Consider these upgrades:
- Upgraded Intercooler: A larger intercooler will help reduce intake temperatures, improving performance and reliability.
- Oil Cooler: An upgraded oil cooler will maintain optimal engine temperatures during high-performance driving.
Exhaust System Upgrades
An efficient exhaust system is crucial for maximizing power. Upgrading the exhaust system will help reduce back pressure and improve overall performance:
- High-Performance Downpipes: These will help improve exhaust flow and reduce turbo lag.
- Cat-Back Exhaust System: A performance cat-back exhaust will enhance sound and performance while reducing weight.
Tuning Your M4 Competition
Once you have installed your forced induction system and supporting mods, proper tuning is essential to achieve optimal performance. A professional tune will ensure that your engine runs smoothly and efficiently, maximizing power while maintaining reliability.
- Dyno Tuning: A dyno tune will measure your vehicle’s performance and make adjustments for the best power output.
- ECU Remapping: Remapping the ECU will optimize fuel and ignition maps for the new setup.
Conclusion
Building a 700+ horsepower M4 Competition requires careful planning and execution. By selecting the right forced induction system and supporting modifications, you can create a high-performance vehicle that delivers exhilarating power and driving experience. Remember to prioritize tuning to ensure your modifications work harmoniously together, allowing you to enjoy the full potential of your enhanced BMW M4 Competition.
