Benefits.
Why fit a complete damper & trigger assembly, not just a bolt on trigger wheel?
We have seen lots of different methods for attaching a crank trigger and sensor to an XK engine – some better than others. In all of the engines, we have seen the standard Jaguar harmonic damper has been well past its use by date! The bonded rubber is almost always perished if it is the original. Bolting a trigger wheel to the front face of the harmonic damper is easy but then making a suitably rigid crank sensor mount isn’t. The sensor mount must be rigid enough to maintain a close air gap to the trigger wheel or at high load/rpm the signal will start to be lost and the engine will misfire. It’s one of the most common problems we see in fuel injection installs. The standard Jaguar harmonic damper is a compromise between cost saving and performance – it’s not great! The ATI units are designed for both road and race applications, they are used extensively in motorsport on these and other high performance engines. Why would you fit an inferior damper after an expensive engine rebuild?
