So browsing the wonderfull ebay world and came across this:
http://cgi.ebay.com/ebaymotors...wItem


I know I know,al these harmanic dampener BS. But beyond that, you think its a sturdy enough part to run on the car? I mean 1lb, thats the big picture here. And for 40 bucks, you cant beat that! It appears to be the same design as UR pulleys. May give it a shot. I really got nothing to loose, I mean my cars leaking and burning oil like crazy. leme know what you think

heres another one,,, more money but still nice: http://cgi.ebay.com/ebaymotors...wItem

 

I think it looks like a hella good buy. I am gonna get one. 4lbs of rotating mass lost for $40. Well worth it!! I wonder if I can check the balance some how (HMMMMMMM) I work in machining and am gonna spin it on a lathe and let you guys know how it checks out. Gimme a couple weeks too get it and check it out and Ill get back to ya.

Thanks

honestly....i have heard of people running on UR for years now....no signs of anything....so Im gonna go for it

 

hellz no i wouldnt buy that, its a knock off, how do you know if its balanced or not, it coud throw your whole motor off and jack things up but give it a try its your ride.

 

^lol....its not balanced, the only one that is balanced is the stock

 

I'd take it to a machine shop and have them check to see if it's balanced. I thought about getting one but there isn't an eBay knockoff of a standard crank pulley (all underdrive)

 

by balanced do you mean round? meaning when rotaing its not wobbleing......its cnc machined guys....it has to be.

 

Although that pulley probaly wont screw up anything for the amount of time you have your car its still possible.

I think some of you are missing the point, with your engine spinning at high rpms, even the littlest of vibration in the wrong place can do harm. Just think of how your crankshaft works and then having a piece on the end thats not harmonically balanced, i would venture a guess that over time it weakens the crankshaft.

If you want to rev faster, get a flywheel, i doubt you will be able to tell that much.

no no, think of a tire and wheel. There both round right? If you dont balance the wheel on a machine then at high speeds your going to feel it through your steering wheel. Im thinking this same concept applies to the pulley and crankshaft.

 

Ebay pulleys.. you guys must not like your cars.

Could slip, could cause screwed up vibrations, could do alot of messed up things. Buy quality for your engine unless you just dont care.

 

I have a bomz racing pulley, which i know is not bomz. And my engine is high mileaged 166k, and no problems. Besides is a 4 cylinder there isn't much to balance, is not like a v6 or v8. I think the crank pulley is a good investment.

 

too many people on here are cheapasses. its not worth the risk.

Some people just make blanket assumptions without knowing **** about a product.

Don't get me wrong, it may be crap. But noone one here knows for sure yet.

i noticed that your profile reads you built a H23 vtec. How involved was it? im planning on doing the same thing also. im swapping in the JDM H22 and keeping the USDM H23 and building it up NA with the vtec conversion. Any advice you can give me being that you did it yourself?

 

im comparing it to the UR pulley.....like I said beyond the point that there is no crank pulley out that has a harmonic dampaner already on it. So compared to the UR pulley which is supposed to expletive your **** up anyway....or so people say, why not pay 100 bucks less for the same thing. imo its the same. Whatever

Thats the problem with it though, since its so light, balancing it would sacrafice structural integrity. Stick with what you know is best...

good idea, but it doesn't apply. if the thing was made on a lathe, it is round, and it is balanced as long as the material is consistent (which it is)

wheels are not made on lathes, or tires lol.

 

The harmonic dampener is designed to dampen the vibrations cause by the slight unbalence of the crank and rods.

It is the same product, but with knock-off companies like that the error is in the details. Maybe the keyway is a mm too small, maybe the pulley is a mm too wide, maybe the instructions suck, etc.... I don't think the pulley would be complete garbage, but you may find something wrong. Give it a try and see what happens.

 

Okay its funny how alot of people knock these things that go on ebay but to be honnest alot of the major companies knock eachothers designs anyway so just cause it maybe ebay doesnt always mean its crap. Intakes and headers even springs alot of times are copies and perform just as well, even worse the people who give there opinions on the ebay stuff havent even tryed them out so their opinion is pointless so unless someone has gotten the ebay parts tryed it and can make a unbiased opinion then I will listen untill then its pretty much hearsay give it a try or compare the UR to the ebay one SOMEONE and give us some REAL results not just made up ones

 

if a company spent the appropriate amount of money on producing this pulley, they would sell it for more....so i dont think its fair to say that its as good as the very expensive ones, but i doubt its hugely different...

that said, i dont think anything bad will come out of this one that wouldnt come out of a UR one or something like it....

and there is no harmonic balancer on your motor, that is what v6s and v8s have.....you have a crank pulley with a little rubber dampener on it....

harmonic dampeners are for externally balanced engines, hondas are internally balanced.....once you are running huge stroke and really high rpm, a harmonic dampener would do good on your honda motor

i hope that that clears up some of the misinformation coming from the altezza light crew....

 

I've run a 20$ one for years in my race engines.. I would not run them on a street car though..

Nobody said that, the message is " you get what you pay for"...

 

anyone know where I can get a Single belt design UR pulley?

I wouldn't use anything but the Unorthodox Racing pulleys if I were you.
