I found one online and the price was pretty good. Anybody have any pointers for the install? Who has one? Did it make a difference you could notice? This is just the lightened version not the under drive one.

 

i have heard some NASTY things about udp's. i wouldnt even go NEAR these things.
its not worth the TEENY-TINY positive that they bring.

 

Great. Just what I wanted to hear. I thought Rochester was running one?

 

Nice, the UR one is fine . Its the 40$ ebay ones you can't trust.

Only bummer is its only good for 1-3 hp but every bit counts.

 

That's a little over-the-top.

Gamer, you should feel a little extra low-end responsiveness to the throttle. However, don't be fooled by simply revving the car in neutral and thinking, "Holy cow!" as the tach jumps in a way it doesn't normally. Having the transmission engaged is a wholly different matter. The gains are there, and they're real. But they're also small, and will become the new normal in a day or two.

Is it worth it? Meh, everyone has a different opinion. If you're spending $200 - $300 for a new one, then I'd say no, it's not worth it. But since you found yours online, I'm thinking money well spent.

Good find. I hope it's good quality. Doesn't look like Unorthodox Racing (UR).

I am. But that should mean absolutely nothing to anyone. If I told you I like to wear big shoes and a clown nose, would you run out to your nearest novelty store?

I don't think so.

 

i didnt mean to **** on your parade, but seriously these things have caused some serious damage.
and with our engines and the oil issues, i would stay away from anything thats going to cause the crank any added vibration.

 

See what can happen with a 2-part crank pulley?

http://www.twinturbo.net/nissan/300z...ank-pully.html

The UR pulleys are single-piece. Had mine on the car now for 2 1/2 years. I'll say this much for it, when you have both pulleys one in each hand, you will have a WTF moment, and there's no way you'll put the heavy one back on the car.

 

Poorly designed pulleys can have severe side effects because of too much underdrive of the alternator, power steering, and/or air conditioning units, which are not spinning fast enough. (Too much underdrive for a race car is not much of a concern, but for a daily driven vehicle it can be a major annoyance.)

Changing the original crankshaft pulley can have negative effects if the replacement pulley is not manufactured properly. A crankshaft or accessory pulley that is not machined or balanced properly can cause severe damage.

 

Seen more DE-K's like that than DE's.

The UR has been on my car for ages, I've owned it since April '09 and it was put on long before then.

 

All true. However...

 

'Underdrive' pulleys cause issues...'Lightened' pulleys just help to free up lost hp, even if minimal.


*as pointed out before my post

 

Oh yeah... I'm on the lightened underdrive... Woops

Hey guys

 

The underdrive is so minimal you will not notice a thing unless maybe you have a 2000 watt sound system. Either pulley will be ok as long as its a UR.

 

I think these pulleys are a waste of money. They dont do anything.

 

 

Disagree...they don't add 100hp, but they do free up wasted energy moving parts that robs power from the wheels. Even if it is 3-5hp...they work.

 

Its a Unorthodox(Spelling?) Racing one and I got it for 50 bucks shipped. Couldn't pass that up. And I figured that another member is running one without ill effects (Rochester) so I said why not?

 

You think a lot of things

 

Wait, you mean you DON'T wear big shoes and a clown nose? I gotta go find my receipt...

 

HEY MAN!! If you rockin it then it must be great!!! I'm gonna go buy me a clown nose too just like ROC!!!

 

I have the UR UDP, you can actually feel the "under drive". For an AT, I don't if it's my foot or the pulley , but it accelerates pretty quick. The unorthodox pulley is the only one I would get.

 

Cool. I don't recall mine looking like that, but it has been a few years.

And another check in the win column: you can use OEM-spec belts.

 

What's with all the negativity?

To start things off, my driving habits...

...I drive it like I stole it and always will.

Anyhow...

I purchased a Ralco RZ Performance Lightened Crank Pulley from eBay for the cheap little over a year ago. I have put 15k miles on the car and have NO issues what so ever.

This came in handy with the BOP. Since you lose a little low end with the BOP, this allows for some of that to return. Other's have said the same.

For the price, it was worth it. Placebo effect? Not a chance...

Thread installing it. http://forums.maxima.org/5th-generat...-pictures.html

 

Was going to get the UR one but seen somebody go with the Ralco Pulley did the same got it for 70 bucks off ebay, and diff felt the difference dont know on power but on acceleration it was there...and had it on the car for like a year and like 3 months, with no problems at all....then somebody totaled my car.....

Holy **** bite it off off NISMOPC... got it off the thread he put up.

 

You know, every time you do something to benefit the upper end, low end responsiveness suffers. It's not that it gets worse, it just seems less than all that because you've added power at the upper-end.

So if you can reclaim a little energy down there, I say do it. Particularly if you've deleted the VIAS from your 5.5 gen.

 

Ralzo and all other $40 ebay pullyes are junk, consider yourself lucky the thing didnt fall apart yet.


A few years ago I purchased the motostorm when it came out for my 4thgen, was a cheap 2 piece pulley. After about 5k I started to feel a vibration under acceleraton that got worse with higher RPMS. Couldnt figure it out to save my like, took me 6 months untill finally a belt shreaded on me... Im lucky it wasnt anything major.

The pulley pretty much started to fall apart were its bolted together. And started to wobble , and it tunred out to be the cause of my vibration.

Buy UR if you want to buy a pulley other wise keep your stock one.

 

And that was the issue...

I recall several guys getting the one piece Ralco and not having any issues with them. I don't consider myself lucky. I consider it a nice pulley, especially for the price.

 

Maybe its just me...(or my sprint booster ) but I really didn't notice too much of ANY loss in low end when I installed the BOP. I noticed the high end gain though!!! Got even better when I added the SRI. After I installe those JWT S1 cams going to be ignorant!!!!

 

I would never go for a 2 piece pulley. And thanks for the link on the installation!

 

Ive modded a few cars in my years , and ive never heard of RALCO .

Just remeber when it comes to mods, you always get what you paid for.

 

I've got one as well no issues at all, and at the price definitely worthwhile. Good find.

 

They've been talked about and used on our gens since 2008. Some feel the same as you. Some don't...

...I'm one that doesn't.

 

My free STS mod disagrees with you.

 

The first mod I did to my car was the Unorthodox racing underpulley. I have had zero problems with it. The car has 265k kilometers, with original alternator and still running strong.

 

Is it made by " RALCO "

Prob not, if you made it yourself then im sure its fine..

 

Search on "free sts" and you'll get what I'm referencing.

However, that's a rare exception to your rule, pointed out only to mess with you. Usually, the get-what-you-paid-for rule is a good one..

 

you know ali's pulley didnt do anything lol. The only thing it might do is make the engine rev up faster when its not under load lol. My light weight flywheel didnt add power it only helps me rev match better.

 

Every bit helps specially for slow 3.0s

 

I have one just to say that I have one.

 

Stillen is good value then, is it?
