No way would those ever go on my car. Pulley sets from the high dollar brands caught a bad rap, let alone the ebay junk...

no thanks.

Think this product through.

IF they turn out as good as name brand pulleys, you may have just wasted your money without any performance benefits or gained a slight increase somewhere in the powerband maybe.

IF they turn out BAD, you may need to replace internals. I know, very fun stuff but not necessarily a good idea to risk your motor over spending a few hundred more dollars for a product developed by companies' with real R&D departments.

This said, I have the ebay DP and TMIC. Eventually I will have the turbo inlet too. But those designs are not nearly as critical as pulleys'.

Actually these pulleys don't drive anything that is critical to the internals of your motor. If one of these was to fail it would be no different then a drive belt failure. Now if they were timing gears, then yeah I would say think very carefully before installing. But just pulleys for some accesories? Not that big of a deal as long as you don't mind taking the chance of being stranded.

you have no idea what your talking about... if the crank pulley fails... it can cause major damage.

If one of these pullies fails, you'll only run out of electricity, or have to drive without Powersteering.
That's the only stuff connected, so this won't screw up anything vital.

Its all about balance and proper manufacturing.

Perfectly balanced pulleys are all the same. Some weigh more, others less, and distance of mass away from center can vary by brand and design. But if it breaks or is misbalanced problems can arise. Similar to paying some serious cash to have your motor internals fully balanced. Ferrari doesn't even make fully balanced crankshafts or camshafts everytime. Quality control takes out "bad" pieces. Ebay companies do not typically have QC on the same level.

Just think of what can actually happen if something spinning as low as 3k rpm breaks and busts a belt and the pulley breaks apart. Do you really think there will not be any collateral damage? Imagine Nolan Ryan on crack with a sledgehammer in your house. How does it break in the first place? Bad casting materials, imperfect mold, bad hardening process, poor design, lots of heat and stress from something like an engine, spinning to 7250rpm or more, poor weatherproofing which leads to premature rust and degradation, etc....

That being said, I will eventually get lightened pulleys too
