I can't speak for the ZPI product, but I have seen and used many different NST pulleys over the past few years and I have never seen anything like this. I can almost guarantee that if you were to take off 10 properly installed pulleys you would never see anything like this on a properly built and installed pulley. I never have seen anything like this, and that includes NST pulleys for Civics, MR2s, tCs, etc.

 

Looks like it got nicked during the install. I don't think the integrity of the pulley has been compromised. It is fine and ready to be reused.

 

Would you buy this? Cause if you want it make me an offer.

ZPI I'm not going to say no to a free one or a refund it would be nice to get some of my money back since I was going to sell it.

 

*tisk* *tisk*

 

I have 2 turbo'd daily driven tC's that run perfect. My POINT is to everyone not just ZPI pulley owners. If I take a product off my car and its broken, then I'm no longer a believer in the product so sue me. I dont care who you are or what you use to install pulleys but these things are not hard to slide on the crank. Anyone with have a brain could put a pulley on without making this kind of damage. I believe this came from daily driven use. And as for that comment about some stock pulleys looking the same as mine ZPI pulley. Well I had 30,000 miles on my stock pulley and its fine. The ZPI with 10,000 miles looks like this.

 

Thread cleaned. Keep it that way!

 

hmmm fresh start... thats always nice

 

Now if we can only stop people from rude PM's we are set.

 

You bunch of retard sons of .............

heh heh.. just kidding Some people just have nothing better to do than start crap though.. the pms.. that is just dumb!

 

I was wondering when the mods where going to clean this up.

Anyhow Ben, I did notice that when you got the pulley installed, a Small tap from a Hammer to insure a snug fit was done. So, I was just wondering if that tap from the hammer could have created the small chip in the pulley during install, as most have said/point out.

 

Well to be honest its alittle bigger then the pic lets on. Its the only good pic I could get of it though.

For the record, Sorry I'm sorry if I starting any crap. Not bashing anyone, just trying to help out fellow scion owners.

 

More pics would be good if you can get them. I have always believed that if you run a flywheel, that you should not run the pulley at the same time. If on stock flywheel, then you can run the pulley has been my motto. Either one or the other on a boosted car, I wouldn't run both at the same time on a boosted tC.

 

I'll try and get a better pic for ya. Good news is that from the pic that tc2nut4 sent me my crank is fine. Seems like the pulley was the only thing damaged which is a good thing.

 

I don't think one has anything to do with the other. You can definitely use both without any issues if both are built well and are balanced

 

what could happen if you run both in a boosted tc? (cuz im planning to get the ZPI pulley and the CM flywheel)

 

What could happen?

well alot less drag on your engine, faster spooling of the turbo, faster revs, more power, more power, and more power.

I don't see why you wouldn't run both.

 

1. if this did happen from a tiny tap of the hammer wow, thats one crappy product.
2. beeing a tech and making mistakes trust me. this did not come from daily
driving. If it did you would notice it. just trust me on this one.
3. this could be an install error of some kind. I know when you get in a hurry you
make mistakes. I don't know how or what would cause it but I can see it
happening.
4. this is nothing to worry about, if the metal was poor or had defects you would
notice alot more cracking, chipping, ect. than you have.
5. If I didn't already have a pully I would buy this from you. I see nothing wrong
with it other than a small chip. It would have to be sold cheap and monitored
closely buy the buyer.


and last but not least.

this is just my experiance and knowledge I have, and what I have observed. now one take this a proven facts as I may be wrong and do not claim to know everything.

 

^^ I agree with him. Its a pulley, and now its a used one. You put it under a load, and that chip might have been the weakest point on it and it chipped. I know its not a perfect condition pulley anymore, but the key rod will still hold it in place.

 

Why do you believe that?

 

^^^ Yea... im still hearing alot of mixed feelings on this... any input anyone?
