Maximizing Power Through Improved Airflow
Airflow is crucial to the RB26DETT engine’s performance, and one of the easiest ways to increase horsepower is by improving the intake and exhaust systems. The stock intake system on the R34 is somewhat restrictive, limiting the amount of air that can flow into the engine. Upgrading to an aftermarket intake system can help the engine breathe more freely, allowing for more air to enter the combustion chamber and ultimately increasing power. Likewise, the exhaust system can also be upgraded to reduce backpressure, allowing exhaust gases to exit the engine more efficiently. A performance exhaust system not only improves horsepower but also gives the R34 a more aggressive exhaust note. When combined with other modifications, these airflow upgrades can significantly boost the RB26DETT’s power output, making the R34 Skyline even more of a performance powerhouse.
Fuel Delivery: Feeding the Beast
With increased airflow comes the need for more fuel to maintain the correct air-fuel ratio and avoid running lean. Upgrading the R34 Skyline’s fuel system is essential when aiming to increase horsepower. The stock fuel injectors and fuel pump can only handle so much power before they become a limiting factor. Many tuners opt for larger injectors and high-flow fuel pumps to ensure that the engine receives the proper amount of fuel to match the increased airflow from upgraded turbos and intakes. An upgraded fuel delivery system, paired with proper tuning, ensures that the engine remains reliable and that the added power can be delivered safely. Proper fuel delivery is crucial to unlocking the RB26DETT’s full potential, and it plays a critical role in maximizing horsepower.
Cooling Enhancements for Consistent Power
As horsepower increases, so does the amount of heat generated by the engine. To maintain reliable performance and prevent overheating, upgrading the R34 Skyline’s cooling system is essential.
