The C5 Corvette Z06 is a performance icon, known for its powerful engine and sleek design. However, many enthusiasts look to enhance its performance even further, and one of the best ways to achieve significant horsepower gains is through camshaft upgrades. In this article, we will explore the best camshaft upgrades for the C5 Corvette Z06 that can unlock 50-70 horsepower gains.
Understanding Camshaft Upgrades
Before diving into specific camshaft options, it’s essential to understand what a camshaft does. The camshaft controls the timing and duration of the engine’s intake and exhaust valves. Upgrading your camshaft can lead to improved airflow, better throttle response, and ultimately, increased horsepower.
Factors to Consider When Choosing a Camshaft
- Lift: The height the valve opens affects airflow.
- Duration: How long the valve stays open can influence engine performance.
- LSA (Lobe Separation Angle): Affects idle quality and power band.
- Intended Use: Consider whether the car is for daily driving, racing, or a mix.
