ZPIracing Yaris Pulley

[ZPIracing]

Guys we are really excited about the Yaris platform and are here to make some serious performance products. To help with this celebration we have dropped the price on the ZPI crank pulley to 80 bucks.

This is an unreal price drop for the best engineered pulley on the market for the Yaris.

Check it out here

$80 sounds good, although I hear that this pulley is not anodized, as opposed to the one offered by another vendor (who will remain nameless for now). Is there really such a difference there?

Also, pls PM the total cost of this pulley to Mexico City (zip code 11700). TIA!

The other pulley has some advantages, but its also much more expensive.


Just have to ask if that last 1% of performance is worth 50% more $.

[Black Yaris]

I will name them.... do you have any plans on making a full pulley set like NST currently has in the works?
Also, will you offer an anodized version of your pulley?

you guys are sucking up this word anondized like its crack hahaha it does NOTHING for a pulley... and as for the pulley kit, I don't see a big point to it, I have held both the water pump pulley and the alternator pulley in my hands and don't see how much lighter you could make them. Plus the benefits other pullies make is much more minimal then the crank pulley itself, as the crank pulley is directly contributes to reciprocating weight. But hey what do i know.

Yeah that's it. Every other REAL pulley builder in the country uses anodizing but since ZPI does not offer "anondized" it must be useless. And you are right about the other pulleys too, extra weight reduction is a bad thing but that is only because ZPI hasn't offered it yet. ZPI is so awesome because I use their turbo, everyone else sucks

Well I'd say for the $, you really can't beat a ZPI pulley as even one of the first mods.

Any ideas on what the pulley would do in my setup? The other pulleys have shown some modest improvements, I can't imagine the ZPI pulley being much/if at all behind.

nothing eh?

do you know what the actual purpose of anodizing is? To harden the surface of otherwise soft natural aluminum, it also is there to help resist against corrosion, and for those of us in states that use salt on the roads in the winter that can be a problem... I don't know about you, but I find that to be important

[eTiMaGo]

from the depths of my memory of chemistry class... The surface of an aluminium object naturally oxidizes once it is exposed to air, which gives it a hard coat, and hence causes the more than adequate natural corrosion-resistance.

Anodizing, on the other hand, is an electrical process to build up an extra protective layer on top of the oxidized layer. The purpose of this is to enhance the scratch resistance of the aluminium (which is naturally quite soft), but it does not make the whole metal object itself any tougher! Only the exact type of aluminium alloy used, as well as the physical structure of the object will determine its strength. Also, this extra anodized layer can be mixed with a dye, to give the object a different color.

In the application of a crank pulley, I honestly do not see any real, tangible benefits to anodizing. Scratch resistance is not so important, good looks are nice, but once it's installed, you'll rarely see the pulley again...

So, in my opinion, the more important differences between the pulleys comes down to build quality (both look to be more than adequate), weight (which is very very close between NST and ZPI), and pricing. In the end, it's really up to personal preference, and with this revised pricing I would lean toward ZPI, but that's just me!

thanks for the back up etimago.. and just for the fyi YarisGuy. I would consider Unorthodox Racing to be one of the largest manufacteurs of crank pulleys out there.... kinda suprising that 95% of their pulleys aren't anondized... hmmm interesting. As for the accessory pulleys more power to you if you want to buy them.... just letting you know if you want to go fast your hundred+ dollars could be much better spent elsewhere. Spend your money how you want, I'm just sharing with you my knowledge.

Another question: Does this pulley come with a vibration dampener? If not... why not?
(I know I asked this before, but that was for the NST so it doesn't count)

[turboyaris]

no it does not... to better clarify and because i dont feel like typing this much, and unorthodox has done a good job explaining it already here is a copy from their website faq section.

4) "Is my crank pulley a harmonic/torsional/vibration damper or a harmonic balancer?"

People are getting their crank pulleys confused with the harmonic dampers found on some V6 / V8 engines. "Harmonic Balancer" is a term used loosely in the automotive industry. Technically, this type of device does not exist. The "balancer" part comes from engines that are externally balanced and have a counterweight cast into the damper, hence the merging of the two terms. None of the applications we offer use a counterweight as part of the pulley, as these engines are all internally balanced.

The pulleys on most of the new import and smaller domestic engines have an elastomer (rubber ring) incorporated into the pulley that makes them look similar to a harmonic damper. The elastomer in the OEM pulley serves as an isolator, which is there to suppress natural vibration and noise from the engine itself, the A/C compressor, P/S pump, and alternator. This is what the manufacturers call NVH (Noise Vibration & Harshness) when referring to noticeable noise and vibration in the passenger compartment. It is important to note in these applications, the elastomer is inadequate in size and durability to act as an effective torsional damper. If you look at the pulleys on some imports there is no rubber to be found at all. We have samples of these, mostly from Acura/Honda, the Nissan Altima, 1.8L Eclipse, 2.3L Fords, Chrysler 2.2L's, and 1.8L VW's, to mention a few. This is not to say with our pulleys you will hear a ton of noise or feel more vibration from your engine compartment. Most owners who have installed our pulleys notice the engine actually feels smoother. This is result of replacing the heavy crank pulley with our crank pulley. NVH is variable and unique to every car. NVH will increase with the installation of an aftermarket intake and/or exhaust, for example. Think of OEM intake systems in newer cars, they use baffles and resonators in the intake to quiet all the intake noise. Aftermarket intakes eliminate these resonators and create dramatic increases in engine noise from the throttle opening and closing. So to most tuners, certain types of NVH can make the driving experience more enjoyable.

The purpose of a traditional harmonic damper is to protect against crank failure from torsional movement. This is not necessary in most modern engines because of the many advances in engine design and materials. Factors such as stroke length, displacement, inline, V configurations, piston dwell time, piston pin off-set, power output, etc., do determine when and how these harmonics and torsional movements occur.

Again, there is a lot of internet hearsay about crank pulleys. When engine problems occur, too often people are quick to blame the pulley first, rather than taking the time to look logically into why there was a problem. We hope that after reading this you will understand the crank pulleys better.

ZPI is offering a great deal on a product and all I read is questions and complaints about how it's not anondized?

Thanks for the deal ZPI!

[ZPIracing]

WOW!! We just wanted to run a special and let some people get a great deal on a great part and we started WWIII.

We once did offer our pulleys in a hard anodized option. A hard anodized option will add strength to the pulley. After a few years of offering this and with more testing and customers hitting 80-90k miles with a pulley we realized there is no point. A hard anodized coating will off extended strength. The anodized options offered by most are to appeal to the cosmetic side of the product on a part that you can not see.

Our pulleys are CAD designed & CNC'd from 6061 Aluminum billet they are built better than the OEM pulleys they replace. We do not offer them in any other size other than stock to prevent any negative affect on a street car. We do not offer a pulley set because to power gained from these in OEM size is minimal at best. Power can be found in running an underdrive pulley but the potential ill affects of doing so are not worth it in my opinion.

We offer a 10year warranty on our pulleys against defect most of you will not have this car that long and the pulley will more than likely last longer than the engine so we have no fear. If we thought anodized was a viable beneficial option we would offer it, we do not so we don’t.

[PetersRedYaris]

I have to agree with eTiMaGo. Anodizing is un-nessasary for a crank pulley. However, if two pulleys were to cost the same and one was anodized, the choice would be obvious.

I'm just a little leary of ZPI... In their turbo kit post, they claim they would never release any item with their name on it if it wasn't "perfected". How doe's that explain at least 3 exhaust systems, that I know of, that didn't even come close to fitting? about ZPI.

Again you have put your lack of knowlege on display. Unorthodox pulleys ARE in fact anodized. Good job fella

The real question you should be asking is would you feel better buying a product from a SPECIALIST, in this case Unorthodox or NST since they build and develop hundreds of pulleys each year, or some other company who copies stuff!

And where was ZPI the entire time while these people were having problems with their exhaust systems? Oh yeah I remember now, they were leaving emails and phone calls unanswered. Now all of a sudden they are back with lower prices. All their products are perfected
