The Mitsubishi Lancer Evolution X, often referred to as the Evo X, is a beloved vehicle among car enthusiasts and track racers alike. With its turbocharged engine and all-wheel-drive system, the Evo X has been a staple in the tuning community. This article explores various modifications that can help achieve 400 wheel horsepower (WHP) and how these upgrades contribute to improved lap times on the track.
Understanding Wheel Horsepower (WHP)
Wheel horsepower is a measure of the power that is actually delivered to the wheels of a vehicle, as opposed to the engine’s horsepower, which is measured at the crankshaft. Achieving 400 WHP in an Evo X requires a combination of engine performance upgrades, tuning, and weight reduction. This section will delve into the significance of WHP and its impact on track performance.
- WHP is a more accurate measure of a vehicle’s performance on the road or track.
- Higher WHP generally translates to faster acceleration and improved lap times.
- It is crucial to balance power with handling and braking for optimal performance.
Essential Mods to Reach 400 WHP
To achieve the coveted 400 WHP mark, several modifications are necessary. Below, we discuss the most effective upgrades that can be made to the Evo X.
- Performance Turbocharger: Upgrading to a larger turbocharger can significantly increase airflow, resulting in more power.
- Upgraded Intercooler: A high-performance intercooler helps keep intake temperatures low, improving efficiency and power.
- High-Flow Fuel Injectors: These injectors provide the necessary fuel flow to support higher horsepower levels.
- Aftermarket Exhaust System: A less restrictive exhaust allows for better airflow, reducing turbo lag and increasing power.
- ECU Tune: A proper tune is essential to optimize the engine’s performance with the new modifications.
Impact of Weight Reduction
Reducing the weight of the Evo X can drastically improve lap times. A lighter car accelerates faster, brakes better, and handles more nimbly. Here are some effective strategies for weight reduction:
- Remove Unnecessary Components: Stripping out non-essential parts such as rear seats and sound deadening material can save weight.
- Lightweight Wheels: Upgrading to lightweight forged wheels reduces unsprung weight, enhancing handling.
- Carbon Fiber Parts: Replacing stock components with carbon fiber versions can significantly cut weight.
Suspension and Handling Upgrades
With increased power comes the need for better handling. Upgrading the suspension system is crucial for maintaining control and improving lap times. Here are some key upgrades to consider:
- Coilover Suspension: Adjustable coilovers allow for fine-tuning ride height and damping settings.
- Upgraded Sway Bars: Stiffer sway bars reduce body roll, improving cornering stability.
- Performance Tires: Investing in high-performance tires enhances grip and traction on the track.
Braking System Enhancements
As power increases, so does the need for effective braking. Upgrading the braking system is essential to ensure safety and performance on the track. Consider the following enhancements:
- Big Brake Kit: A big brake kit provides larger rotors and calipers for improved stopping power.
- High-Performance Brake Pads: Upgrading to performance pads enhances braking performance and reduces fade.
- Stainless Steel Brake Lines: These lines improve pedal feel and reduce the risk of brake line expansion under pressure.
Real-World Testing and Results
After implementing these modifications, many Evo X owners have reported significant improvements in lap times. Testing on various tracks has shown that achieving 400 WHP not only enhances straight-line speed but also contributes to better cornering and overall handling. Here are some results from real-world testing:
- Improved lap times by an average of 3-5 seconds per lap after modifications.
- Increased driver confidence due to enhanced handling and braking performance.
- Better throttle response and acceleration out of corners, leading to faster overall speeds.
Conclusion
Achieving 400 WHP in a Mitsubishi Evo X is a combination of strategic modifications, weight reduction, and enhanced handling and braking systems. These upgrades not only improve power but also significantly impact lap times on the track. With the right approach, the Evo X can be transformed into a formidable racing machine that excels in both speed and agility.
