Excited! My UR Pulleys arrived, review soon

fanbanlo · 10-09-2009, 07:47 PM

They have arrived!

Bought them off eBay.ca, along with the suggested Gate belt (K070683) (Amazon.com), and I'll have them installed tomorrow. That guy only quoted me CAD$75 for install... hopefully everything goes well.

So excited........ Hopefully I can feel their existences once installed.

Awesome upgrade... I have the same pulley kit as well and love the results!! Hopefully see ya at the next meet icemiko sets up for us

Wow 75 CAD for pullies install? That's the best price I've seen. I'll be waiting for a review because this is one of my favorite less mass rotation mod.

what does installing these pullies do. be honest.

? lighter weight, over/under drive a little, might make a big diff in performance, I don't know.. yet.

light weight reduces the mass adds a few more HP.. Great low buck easy hp upgrade you can get IMO.. minus the PITA install

the crank pulley is a biotch to remove.. hope you have a huge impact gun for it or a pulley removal tool

keep us updated cause pulleys is one of the mods that i want to do in the near future.

With the pullies being lighter and of smaller diameter, the engine doesn't need to work as hard to rotate it. Now if you know phyics and angular momentum, even the slightest weight reduction in a rotating object will make a difference in how it rotates. The pullies will make the engine more responsive much like what a light weight flywheel can do. Now I don't think this makes the car faster in the long run, just more responsive jumping off the line.

Now if you add lightweight flywheel and lightweight wheels, you will jump off the line much quicker and you will feel your car being much more responsive. You will feel that the car is faster but it really isn't. It's just the throttle response and the engine revving has become faster.

Not sure what you paid but in the future let us know and we should be able to beat or match ebay prices.

I don't mean to hijack the thread, but I got a pulley question for you guys. On heeltoe's website the description of the UR pulleys say:

"Our pulley sets provide most of the power gains through weight loss (80-85%). The remaining part of the gains from these pulleys comes from underdriving of all the accessories (15-20%).However, we do not push underdriving for two main reasons. First, it is important to keep charging systems, air conditioning, power steering, and water pumps moving fast enough for every day driving. Second, not much horsepower is gained from extreme underdriving.

In most applications all of our underdriving is done with the crank pulley, not the accessory pulleys. This is done so maximum weight loss can be achieved at the crank where most of the horsepower gains are found."

What does the bolded mean? Do the pulleys affect performance of AC, power steering etc?

Well the UR pullies are smaller in diameter than our stock ones. So whatever Honda engineered it's OEM pullies is what is optimum for all of the system ie. electrical, ac, power steering. Since the UR pullies are smaller, there is less "charging," thus the reason why the word underdriving is used. But many of the UR pulley users haven't complain and I read somewhere that you can power at most a 600 watt system. That means if you have sub woofers that can bump at 1000 watts, the UR pullies won't crank enough power to the electrical system.

So basically, if you're not an audiophile, don't worry about underdriving your car with these pullies.

The reason why some people would push underdriving is for better performance and I do believe results in better HP. UR basically didn't shrink their pullies enough compared to some competitors so they backed up their reasons by telling you about underdriving and how it can affect the overall systems of the car.

So to answer your question, YES, technically it does affect the ac, power steering, but I would say that it's entirely not noticeable. It's like taking out a passenger seat. Technically your car is lighter, but you're not gonna feel a difference.

I read somewere that it works better on automatic transmitions, is that true? and do you keep the same belt or wider one?
I'm looking to get the UR pullys too.

cYn · 10-10-2009, 02:36 AM

Oh, there's also claims that they got 1-2 more mpg with these pullies.

willy18 · 10-10-2009, 03:31 AM

I was thinking about these today too. I'm very interested to hear your review.

You can use RSX-S or CRV belt. Most GTA members use RSX-S belt; they are a tad shorter than TSX belt and it's perfect fit.

I love mine but it's time to part out
