The RB20DET engine, a popular choice among performance enthusiasts, is known for its robust design and tuning potential. One of the key components that can significantly enhance the performance of this engine is the camshaft. Brands like Tomei and Jun have developed high-performance camshafts that improve power output and response. In this article, we will explore how these camshafts work, their benefits, and what makes them stand out in the competitive aftermarket landscape.
Understanding Camshafts
Camshafts play a crucial role in an engine’s performance by controlling the timing and duration of the valve openings. The design of a camshaft can greatly influence the engine’s airflow, which directly impacts power and efficiency. In the context of the RB20DET, upgrading to a performance camshaft can unlock additional horsepower and torque, making it a popular modification among tuners.
How Camshafts Affect Performance
The performance of an engine can be significantly improved by modifying the camshaft profile. Key factors influenced by camshaft design include:
- Lift: The height to which the valve opens, affecting airflow.
- Duration: The length of time the valve remains open, impacting the engine’s ability to breathe.
- Overlap: The period when both intake and exhaust valves are open, affecting scavenging.
