The .7T turbo upgrade is a popular modification among car enthusiasts looking to enhance their vehicle’s performance. By increasing boost levels from 20psi to 30psi, drivers can experience significant power gains. However, this upgrade comes with both pros and cons that should be carefully considered before making the switch.
Understanding Turbochargers
Turbochargers are devices that increase an engine’s efficiency and power output by forcing more air into the combustion chamber. This process allows for more fuel to be burned, resulting in greater power. The .7T turbo is designed for specific performance applications, and understanding its capabilities is essential for maximizing its benefits.
Pros of the .7T Turbo Upgrade
- Increased Power Output: Upgrading to a .7T turbo and increasing boost to 30psi can lead to substantial power gains, often exceeding 100 horsepower.
- Improved Throttle Response: Higher boost levels can enhance throttle response, making the vehicle feel more agile and responsive.
- Better Acceleration: The additional power allows for quicker acceleration times, improving overall driving experience.
- Tuning Flexibility: The .7T turbo can be tuned for various performance levels, providing flexibility for drivers who want to customize their setup.
- Enhanced Performance on Track: For those participating in motorsport, the upgrade can provide a competitive edge.
Cons of the .7T Turbo Upgrade
- Increased Engine Stress: Higher boost levels can put additional stress on engine components, potentially leading to premature wear or failure.
- Fuel Consumption: Increased boost can lead to higher fuel consumption, which may not be ideal for daily driving.
- Cost of Upgrades: The initial cost of the turbo upgrade, along with necessary supporting modifications, can be significant.
- Potential Reliability Issues: Running higher boost levels can compromise reliability if not properly tuned and maintained.
- Legal and Emissions Concerns: Modifications may affect emissions compliance, leading to potential legal issues.
Power Gains: 20psi vs. 30psi
One of the most significant factors in considering the .7T turbo upgrade is the power gains associated with increasing boost from 20psi to 30psi. Here’s a breakdown of the expected gains:
- At 20psi: Typically, vehicles running at 20psi will see power outputs ranging from 250 to 300 horsepower depending on the engine and supporting modifications.
- At 30psi: Increasing the boost to 30psi can push power outputs to 350 to 400 horsepower, significantly enhancing performance.
Supporting Modifications
To safely and effectively run a .7T turbo at 30psi, several supporting modifications are recommended. These upgrades help manage the increased power and ensure reliability:
- Upgraded Fuel System: A higher flow fuel pump and larger injectors are necessary to provide adequate fuel for the increased air intake.
- Enhanced Cooling System: An upgraded intercooler can help manage the increased heat generated by higher boost levels.
- Stronger Engine Internals: Consider upgrading components such as pistons, rods, and bearings to handle the increased stress.
- ECU Tuning: Proper tuning is essential to optimize performance and prevent engine damage.
- Exhaust Upgrades: A high-flow exhaust system can help reduce back pressure and improve turbo efficiency.
Conclusion
The .7T turbo upgrade, particularly with an increase in boost from 20psi to 30psi, offers significant performance benefits. However, it also presents challenges that must be addressed through careful planning and execution. By weighing the pros and cons, and considering necessary supporting modifications, drivers can make informed decisions that align with their performance goals.
