I drive across the Tacoma Narrows Bridge's surviving twin sister at least twice a week--the Bronx-White Stone Bridge.
EDIT: Not saying I agree with zer0; I'm just talking about the bridges. They've reinforced the $%&@ out of that bridge since the one in Washington went down and the damn bridge is in a perpetual state of construction.
With regards to the topic on hand, I'm with Lance, not in particular to the tC, but I've heard plenty of stories of solid crank pulleys killing the oil pump on other cars, and an oil-starved engine is a dead one.

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.
Do you?
The factory, 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.

The answer is that there is nothing in particular about tC that in any way makes the swapping of a solid crank pulley in place of the stock harmonic damper viable with regards to long term reliability--either none who have installed one have driven sufficient mileage to experience related failure or the very few who have do not wish to report it (most likely to save face in the case where they defended the reliability of their setup for the longest only to turn out wrong).Originally posted by zer0@Apr 23 2006, 10:31 AM
I like to see both sides of the story. To the people that answer'd seriously, Thanks for answering my questions.
I do not own a lightweight pulley, the flywheel for me is enough weight savings for now.
Didnt know asking questions was bad on this site.![]()
