No, I want to know why these company would offer such a horrible product? Its gonna destroy the motor, so lets give them away like candy.
I know the companies arent going to warrenty your motor, I just find it odd that almost everyone and their mom is using a solid crank pulley, and havent had troubles yet. Shouldnt the harmfull harmonics destroy your motor as fast as possible?
No, not, "everyone and their mom," are using these--think about the sheer number of cars on the road, and then consider how few among those actually have these on their cars. It's not actually that much, plus the fact that many tuners and modders only keep their cars so long before changing to another, and you'll see that the people who make this type of change to the car probably won't end up being the person who has to deal with related failures. There are also plenty of people out there who are
reporting related failures, so I have no idea why your're saying none of them are. There are not
that many tC owners using these, and of the extremely few who are, they definitely haven't reached sufficient mileage to experience serious issues yet
No, the, "harmful harmonics," do not destroy the engine as quickly as possible. Not everything that's bad will show immediate effects--it's perfectly possible for a modification to parasitically destroy the engine over a longer duration, take 65,000 to 125,000 miles. As Lance indicated, 125,000 miles is nothing
in the realm of true endurance testing. Yes, engines have parts that are only going to last a certain amount of mileage and then need replacement (spark plugs for example), but those are expected maintenance items. There are parts that are designed to never
fail, not even within a half million miles, and those are the ones that are affected slowly over time and fail prematurely in situations like this. Tuners who think to themselves, "well I'm only going to keep this car maybe 100,000 miles, anyway and change to something else eventually," are not going to worry if the harmonic distortion is the result of sheered rods at the 150,000 mile mark.
on the other hand, does
care; they care about the 150,000 mile mark, the 250,000 mile mark and even the 500,000 mile mark. If anything that is not
considered standard maintenance runs the risk of failure due to another component in the equation, that component must
be improved on.
