I recently stumbled across a forum discussing chip tuning of diesel engines. One comment stated that a chip tuned engine should have the cambelt changed at twice the recommended interval.
From my simple understanding, the load on the cambelt is the torque applied by the crank which is being resisted by the friction of the camshaft bearings plus the cyclic load of opening the valves plus inertia effects when accelerating the camshaft.
My guess is that the worst case is either when the engine first fires up, or when being revved from tickover with no load. Either way I can't see that a chipped engine would be much different from a standard one in these conditions. I assumed that the benefit was improved torque higher up the rev range. Can anyone shed any light on this ??
