Never heard of problems with a pulley, less from a conbination of a pulley and flywheel. But, there isn't anyone with ENOUGH mileage to tell if there is a difference. Nothing can yet be proven.

 

ZPI's version 1 pulley was actually the agency power pulley, just with a few dollars extra tacked on..

I currently have it on my car, it's a great pulley.

 

Personal preferance. Just seems like a lot of stress on the engine. So, that's my opinion on it.

 

The Big Evo 16G that comes in the ZPI kits is one of, if not THE fastest spooling turbine of the kits, I don't see you reacting fast enough to the speed the RPM's come at you in 1st, 2nd, and 3rd gear, if you run both a Flywheel and a Pulley. That's MAJOR SPIN ACTION.

 

I would consider it if it were anodized.

 

It is the anodized version.

 

I'm not a expert on anodizing but that pulley look like it is not anodized.

 

I actually think of it as less stress because of the lack of weight, but take in mind that people with this kind of mods go CRAZY and try to take it to redline ALWAYS, just to see the revs go high very fast, get my point? I think that if you treat it nicely, then everything would be okay. :D

 

2. If it isn't the pulleys fault then that means wow, that's a crappy installation job.

 

Here we go again...

 

exactly my point. more power = more fun.

 

This is a pic from ZPI's shop, on the left are anodized pulleys and the right non anodized pulleys. Mine is 100% anodized.

 

Maybe its just the picture but yours looks like a stained bare aluminum unandodized pulley. The pulleys on the left looks anodized dark grey. Not trying to be a *****.

 

no his is anodized, took mine off when my engine blew and looked NOTHING like his, he has anadized, the flash on his camera is making it look "silver" when its not

 

This is an isolated event. It's not a cut and dry case in that your pulley had a defect in it. This seems to be along the lines of:

"quick installation to get a dyno run in to see what it can do"

The pulley is good.

 

Yeah my flash messes up the color. Its just as dark as the ones in ZPI's shop pic.

 

It's anodized no question about that part. The way that the groove tappers towards the "crankside" of the pulley, I'm pretty sure this had to have happend during installation. With the way it spins, I don't think a pulley could make such a chip just from a rotation. If damaged from wear/tear of use, I would think the chip would appear a lot more even, and throughout the entire Key insertion.

 

not to mention with the direction the engine spins, the chip would be on the other side. engine turns counter clockwise, this mark is would be if it turned clockwise.

 

Or maybe the fact that zpi doesnt know what the hell there doing is more like it! See ppl zpi work broken what a surprise!

 

^^^ interesting choice of names there
