Ever heard the saying, Timing is everything? Well, its particularly true when it comes to cam timing. It doesnt make a difference whether your water-cooled powerplant is showroom-stock or aftermarket-modified, the addition of an adjustable cam gear is one of the quickest and simplest ways to gain performance. Whether youre looking to fine tune or compensate for performance modifications, an adjustable cam gear is your key to engine tuning bliss. Looking to increase low-end torque for better throttle response? Advance the camshaft timing a few degrees forward. Want to shift the powerband upward to increase horsepower for better top-end power? Retard the camshaft timing a few degrees back. With an adjustable cam gear, you can dial-in, or degree, your camshaft timing to any setting with ease.
What exactly does an adjustable cam gear do? Simply put, it allows your engine to breathe internally better. Fine tuning the camshaft timing allows for adjustments to both horsepower and torque curves. This is accomplished by altering the Volumetric Efficiency (VE) rating by changing the overall timing of the valvetrain via the camshaft. The VE rating directly affects engine performance in terms of horsepower and torque. Its been rumored that the factory de-tunes camshaft timing purposely for stateside cars. Regardless, factory cam tuning can be bettered to allow for increased engine performance.
We turned to Neuspeed of Camarillo, California, to show the MAX Power readers how simple it is to install an adjustable cam gear on an eight-valve engine. The Neuspeed CNC adjustable cam gear is crafted from 7075T-6 billet-aluminum, which happens to be stronger than steel. Next, the gear is black-hard-anodized for even longer wear and increased appearance. The hub on the Neuspeed cam gear is machined from 6061T-6 aluminum and features locking stainless steel threaded inserts that resist pull out even after repeated adjustments and precision laser-engraved timing marks that allow up to 7 degrees advance or retard in 1-degree increments. In general, advancing the cam timing increases low-end torque, while retarding the timing increases top-end power. Aircraft-grade stainless steel hardware and an Allen hex wrench are included.
