I saw this on their website and thought I would pass it along: NST - The Leader In Honda Fit Pulleys

They have a very good rep on 8thcivic.com and I saw their K20 pulleys as a feature in Import Tuner.

Some pics:

 

I do like the price, but what I don't like is the design. Seems to be designed for more lateral load then axial, in my opinion at least. Can't wait for a review!

 

interesting.

 

Nice find, options are always good!

But 992 grams (35oz).... that means it is the heaviest aftermarket option. Although the price does reflects this.

I also out-right call bull on the manufactures claim of 6-8hp for the Fit.

Here is how it stacks up, lightest to heaviest;
Unorthodox pulley = 461g (540g for both)
Summit pulley = 600g
T1R Pulley = 644g
Mythelogy pulley = 780g
NST pulley = 992g

 

still undampened.

 

^^^ yeah no options as far as dampened ones go. T1R was supposed to make one but they gave up in favor of a solid one because although the MT cars saw nice gains... the AT cars were losing power with it.

 

they say since most hondas are internally balanced, that running an undampened crank pulley is safe.
i don't really trust this... especially for only a couple horsepower.

 

Yeah there is a lot of debate around it; I was worried about it for a while and you have probably read a few of my thoughts on it on other pulley threads.

After doing my research basically no matter how you cut it, the deflection accross the face of the pulley under certain loads will transfer into the crank and engine bearings regardless about how it is internally balanced... that said this applies do dampened pulleys as well, they will also pass some ecentric loads to the crank on load, it is just dampened.

What does this mean? I read a lot of case studies around the problem and it seems that it reduces the longevity of the engine bearings by maybe 20%, I see that being the only drawback. With that said, how long do bearings in the Fit last... I doubt anybody has worn them out yet which should mean this isn't a problem that will be popping up anytime soon for somebody using a pulley. As a precautionary measure you should be inspecting your bearings at around 100K (60K miles for our US friends) and I would be willing to bet you would only have minor wear compared to a car that isn't using an aftermarket pulley.

 

I decided to give their IM screen name a try to ask some questions. First, their screen name is NSTonAIM and the person I spoke to was very friendly and helpful. He explained that they have been in the business of building nothing but pulleys for the past few years and sounded like he was very knowledgable on the topic. We talked for almost an hour on the topic of harmonics and vibrations and what he shared was very eye opening. Second, he gave links to threads on other forums where he said their product was popular. Take a look at the links.

Unorthodox Racing pulleys vs NonStop Tuning pulleys - 8th Generation Honda Civic Forum

NST K20 Kit featured in Import Tuner Power Pages - 8th Generation Honda Civic Forum

The NST pulley is looking more and more interesting, especially after seeing the type of reputation and customer service these guys have.

 

Interesting threads; however for the Fit UR makes a much lighter pulley... more than twice as light as the NST one.

Like NST, UR also has very good service as well.

 

The UR one doesnt say the weight on the web site.. which is bogus. Anywho, 220 for that doesnt seem worth it to me right now. Maybe if i get a hookup somewhere but until then im chillen.

But the powerpages on it looks promising.

The weight was verified by member Xorbe on a scale to the very gram.

 

I don't think the difference in weight between the options is going to be noticeable in our cars. They are all a lot lighter than the stock pulley and the $128 price makes it a lot more affordable for sure. Has anyone tried the NST pulley yet?

 

true true. Good point. Too much weight reduction might be bad too.

 

To be honest I don't know how less weight would be bad?

Less weight on the crank translates directly into less energy required to start accelerating it... which translates into additional power available during acceleration.

Ok, not to be picky but lets put some numbers to this;

So you are betting the car will gain power buy reducing the weight from 2200grams to 992 grams (just slightly more than half) with the NST pulley..... and you don't think there will be a difference going from 992 grams to 461 grams (again, slightly more than half of the NST) with the UR pulley.

 

No. What I am saying is that the main thing is going from 2200 down to a much smaller number. Either down to 992 or 461. This is obviously going to be noticeable. But going from 2200 down to 461 is not going to make much more of a noticeable difference. Either way you are either reducing by 1200 or by 1700. The overall effect is going to be very noticeable, but going to be very similar. That is what I am saying.

In my opinion the performance gains from all of the pulleys (UR, T1R, NST) is going to be very similar. So in the end it probably comes down to the quality of the material, the customer service, the color options, and most of all price.

 

mmmmmm..... t1r....

 

I have Summit pulley in my car and it has about 109000km and still working good.
