When it comes to enhancing the performance of diesel engines, turbo upgrades are a popular choice among enthusiasts and professionals alike. Big-size turbo upgrades, especially those ranging from 64mm to 88mm, can significantly increase horsepower, often exceeding 600 HP. In this article, we will explore some of the best options available in the market and what makes them stand out.
Understanding Turbochargers
A turbocharger is a device that forces more air into an engine’s combustion chamber, allowing for more fuel to be burned and, consequently, more power to be produced. The size of the turbocharger plays a crucial role in determining the engine’s performance characteristics. Larger turbos can produce more power but may also introduce lag, which is the delay before the turbo starts to provide boost.
Factors to Consider When Choosing a Turbo Upgrade
- Engine Compatibility: Ensure the turbo is compatible with your engine type and model.
- Power Goals: Define your horsepower goals to select the appropriate turbo size.
- Boost Threshold: Consider the RPM range where you want the turbo to spool.
- Supporting Mods: Assess if you need additional modifications to support the increased power.
