One Thing we've discovered about the OHC modular motors is that they are highly sensitive to cam timing. Unfortunately, the production tolerances are such that the cam timing can be off significantly ...

If there's an elusive animal in the amateur performance world, then degreeing a cam is it. Few know how to do it, and even fewer understand the benefits. If you're following our 347 build from the ...

At the risk of losing credibility with our readers (assuming I had any to begin with!), I must admit to never having built an engine before. I've done general maintenance, bodywork, welding, complete ...

This diagram shows the major cam events through one full cylinder cycle (two crank revolutions or 720 degrees), beginning at TDC firing. The exhaust lobe and valvetrain is closer to the front, and ...

The hunt for efficient engine valve technology can be a never-ending journey into cam timing, various combustion cycles, and lift and duration adjustments. For that reason, some companies believe ...

A cam phaser is a sprocket which adjusts the position of an engine’s camshaft in relation to its crankshaft and is tuned with a computer-controlled servo. Camshafts control the timing of engine intake ...

BorgWarner has announced a deal to supply variable cam timing (VCT) and engine timing systems for Jaguar Land Rover’s new Ingenium I4 engine line. Based on a configurable and flexible architecture to ...
