The Mitsubishi Eclipse GST is a popular choice among car enthusiasts looking to enhance their vehicle’s performance. One of the most effective ways to achieve this is by safely increasing the boost pressure from 8 PSI to 14 PSI. This article will guide you through the process, ensuring you maximize performance while maintaining engine reliability.
Understanding Boost Pressure
Boost pressure is the amount of air forced into the engine’s intake manifold. Increasing this pressure allows for more air and fuel to enter the combustion chamber, resulting in greater power output. However, it’s crucial to understand the implications of raising boost levels.
- Increased power output
- Potential for engine knock
- Need for additional fuel
- Importance of tuning
Preparation for Boost Increase
Before making any modifications to increase boost, it’s essential to ensure your vehicle is in good condition. Here are the steps to prepare your Eclipse GST:
- Perform a complete engine inspection
- Check for any existing leaks
- Ensure the intercooler is functioning properly
- Inspect the turbocharger for wear
- Replace worn spark plugs and ignition components
Necessary Modifications
To safely increase your boost from 8 PSI to 14 PSI, several modifications are necessary. These enhancements will help your engine handle the increased pressure without compromising reliability.
Upgraded Fuel System
An upgraded fuel system is crucial when increasing boost levels. Here are the components you should consider upgrading:
- Higher-flow fuel injectors
- Upgraded fuel pump
- Fuel pressure regulator
Improved Intercooler
With increased boost, the temperature of the intake air can rise significantly. An improved intercooler helps to cool this air, making it denser and more efficient for combustion. Consider these options:
- Front-mount intercooler
- Upgraded piping
- Intercooler sprayer system
Turbocharger Upgrade
To handle the increased boost, you may need a turbocharger upgrade. Look for a turbo that can efficiently support 14 PSI without causing excessive lag:
- Ball-bearing turbos for quicker spool
- Turbo with a larger compressor wheel
- Wastegate upgrades for better boost control
Tuning Your Eclipse GST
After making the necessary modifications, tuning is vital to ensure your engine runs efficiently and safely. Proper tuning will help you achieve the desired boost level without risking engine damage.
- Use a reputable tuning software
- Monitor air-fuel ratios
- Adjust ignition timing
- Perform dyno testing to optimize performance
Monitoring Performance and Safety
Once your Eclipse GST is tuned and running at 14 PSI, continuous monitoring is essential. This will help you identify any potential issues before they become serious problems:
- Install a boost gauge
- Monitor engine temperatures
- Check for any signs of knocking
- Regularly inspect engine components
Conclusion
Increasing the boost on your Mitsubishi Eclipse GST from 8 PSI to 14 PSI can lead to significant performance gains. By following the steps outlined in this article, including necessary modifications, proper tuning, and ongoing monitoring, you can safely enjoy the benefits of enhanced boost without sacrificing engine reliability.
