The 4G63 engine has long been celebrated in the automotive community, especially among enthusiasts of Mitsubishi vehicles. Its robust design and tunability make it a favorite for those looking to push performance boundaries. In this article, we will explore how a built 4G63 engine, equipped with CP pistons and H-beam rods, can achieve impressive 9-second drag strip runs.
Understanding the 4G63 Engine
The 4G63 is a 2.0-liter inline-4 engine that was produced by Mitsubishi. It features a DOHC design and has been used in various models, including the Mitsubishi Eclipse and Lancer Evolution. Its strong internals and turbocharging capabilities make it an ideal candidate for high-performance builds.
- Displacement: 2.0 liters
- Configuration: Inline-4
- Turbocharged: Yes
Key Components for Performance
To achieve 9-second runs at the drag strip, certain components must be upgraded. The selection of pistons and rods plays a crucial role in the engine’s performance and reliability.
CP Pistons
CP Pistons are known for their high-quality manufacturing and ability to withstand extreme conditions. These pistons are designed to handle the increased boost and power levels associated with high-performance builds.
- Material: Forged aluminum
- Compression ratios: Customizable for specific builds
- Durability: Designed for high boost applications
H-Beam Rods
H-beam rods are another essential component in a built 4G63 engine. These rods provide increased strength and reliability, allowing the engine to handle higher RPMs and power outputs without failure.
- Design: H-beam for improved strength
- Weight: Lightweight for better performance
- Compatibility: Fits various 4G63 applications
Building the Engine for Drag Racing
When building a 4G63 engine for drag racing, several factors must be considered, including tuning, fuel delivery, and supporting modifications.
Tuning for Maximum Performance
Tuning is critical for extracting the maximum potential from a built engine. Proper tuning ensures that the air-fuel mixture is optimized for the best performance, especially under high boost conditions.
- ECU tuning: Essential for performance adjustments
- Dyno testing: Helps in fine-tuning the setup
- Boost control: Necessary for managing power levels
Fuel Delivery System
A high-performance fuel delivery system is vital for supporting the increased power levels of a built 4G63 engine. Upgraded fuel pumps, injectors, and lines are necessary to ensure adequate fuel supply.
- Fuel pump: High-flow for increased demand
- Injectors: Larger size for better fuel delivery
- Fuel lines: Upgraded to handle higher pressures
Achieving 9-Second Runs
With the right components and tuning, a built 4G63 engine can achieve astonishing 9-second runs at the drag strip. This level of performance requires not only engine modifications but also a well-prepared vehicle and skilled driver.
Vehicle Preparation
Preparing the vehicle for drag racing involves optimizing various aspects, including weight reduction, suspension tuning, and tire selection.
- Weight reduction: Stripping unnecessary components
- Suspension: Upgrading for better traction
- Tires: Selecting the right compound for drag racing
Driver Skill
Finally, the skill of the driver plays a significant role in achieving fast lap times. Mastering launch techniques and knowing how to manage power delivery are crucial for maximizing performance on the drag strip.
- Launch techniques: Perfecting the start
- Power management: Controlling throttle input
- Reaction time: Importance of quick reflexes
Conclusion
In conclusion, the 4G63 engine is a testament to the potential of Mitsubishi’s engineering. With the right upgrades, such as CP pistons and H-beam rods, along with careful tuning and vehicle preparation, achieving 9-second runs at the drag strip is within reach. For enthusiasts and racers alike, the 4G63 remains a powerful option for high-performance builds.
