What is the primary benefit of a hydraulic roller camshaft like this one?

Hydraulic roller camshafts reduce friction compared to flat tappet designs. This allows for more aggressive lobe profiles, which can increase airflow and improve engine performance, while also offering better durability.

Why is a valve spring upgrade necessary with this camshaft?

The Xtreme Energy camshaft has aggressive lobe profiles that result in higher lift and faster valve opening. Stock valve springs may not be able to handle these demands, leading to valve float at higher RPMs. An upgraded spring set ensures proper valve control and engine reliability.

Is custom tuning absolutely required after installing this camshaft?

Yes, custom tuning is essential. The camshaft changes how much air enters and leaves the engine, and your engine's computer needs to be recalibrated for fuel and ignition timing to match these changes. This ensures the engine runs correctly and achieves its potential performance gains.

Product Details

This COMP Cams Xtreme Energy camshaft features a 218-degree intake and 226-degree exhaust duration, measured at .050 inch lift. This specific lift profile is designed for Ford 3.8L and 4.2L V6 engines, aiming for maximum performance in strip and street applications. As a hydraulic roller camshaft, it offers reduced friction and improved durability compared to flat tappet designs, allowing for more aggressive lobe profiles that increase airflow into and out of the cylinders.

To take full advantage of the aggressive lobe design in this Xtreme Energy camshaft, a spring upgrade is necessary. The increased lift and duration place higher demands on the valve springs, and using the stock springs can lead to valve float at higher RPMs, limiting performance and potentially causing engine damage. Additionally, custom tuning of your engine's computer is required to optimize fuel delivery and ignition timing for the camshaft's new airflow characteristics. This ensures the engine runs smoothly and efficiently, unlocking the full power potential of the cam upgrade.

Please note that this camshaft is not CARB approved and cannot be shipped to California. It is also subject to California's Proposition 65 warning.
