The Mitsubishi Lancer Evolution X, known for its rally heritage and impressive performance, has become a favorite among car enthusiasts. With the right modifications, its potential can be significantly enhanced. One popular upgrade is the HKS GT II Turbo Kit, which promises substantial gains in horsepower and torque. In this article, we will explore the performance testing of the Evo X equipped with the HKS GT II Turbo Kit, focusing on the gains achieved and the reliability of the setup.
Understanding the HKS GT II Turbo Kit
The HKS GT II Turbo Kit is designed to optimize the performance of the Evo X’s 2.0-liter turbocharged engine. This kit includes a larger turbocharger, upgraded intercooler, and enhanced exhaust components. The goal is to increase airflow and reduce turbo lag while maintaining engine reliability.
Components of the HKS GT II Turbo Kit
- GT II Turbocharger
- High-performance intercooler
- Upgraded exhaust manifold
- Performance downpipe
- ECU tuning software
Each component plays a crucial role in enhancing the overall performance of the vehicle. The GT II Turbocharger, for instance, is designed to provide increased boost pressure and improved efficiency, while the upgraded intercooler helps to keep intake temperatures low, ensuring optimal performance.
Performance Testing Methodology
To accurately assess the performance gains from the HKS GT II Turbo Kit, a series of tests were conducted. This involved baseline runs with the stock setup followed by testing with the HKS kit installed. The following parameters were measured:
- Horsepower and torque output
- Boost levels
- 0-60 mph acceleration times
- Quarter-mile times
- Engine temperatures
All tests were performed on a dynamometer under controlled conditions to ensure accuracy and repeatability. The vehicle was also monitored for any signs of mechanical stress or failure throughout the testing process.
Baseline Performance Data
Before installing the HKS GT II Turbo Kit, the Evo X was tested in its stock form. The baseline performance figures recorded were:
- Horsepower: 291 hp
- Torque: 300 lb-ft
- 0-60 mph: 5.2 seconds
- Quarter-mile: 13.5 seconds
These figures represent the standard performance metrics for the Evo X, showcasing its capabilities as a factory model.
Performance Gains with HKS GT II Turbo Kit
After installing the HKS GT II Turbo Kit and performing necessary ECU tuning, the Evo X was retested to evaluate the performance improvements. The results were impressive:
- Horsepower: 380 hp
- Torque: 360 lb-ft
- 0-60 mph: 4.5 seconds
- Quarter-mile: 12.1 seconds
The gains of nearly 90 horsepower and 60 lb-ft of torque demonstrate the effectiveness of the HKS GT II Turbo Kit. The reduction in 0-60 mph time and quarter-mile time further highlights the performance enhancement.
Reliability and Engine Health
While performance gains are crucial, reliability is equally important when modifying a vehicle. Throughout the testing process, the Evo X was monitored for signs of strain or failure. Key observations included:
- Consistent oil pressure readings
- No signs of detonation or knocking
- Stable engine temperatures under load
- Durability of the turbo components
These observations suggest that with proper installation and tuning, the HKS GT II Turbo Kit can be a reliable option for enhancing the Evo X’s performance without compromising engine integrity.
Conclusion
The performance testing of the Mitsubishi Lancer Evolution X with the HKS GT II Turbo Kit reveals significant gains in horsepower and torque, along with improved acceleration times. The reliability of the setup further supports its viability for enthusiasts looking to enhance their vehicle’s performance. With the right modifications, the Evo X can reach new heights, making it a formidable contender on both the street and the track.
