wish there was a before an after dyno cause i would prob do this if it showed a difference for sure

I agree, a before and after dyno would be nice, but I can't afford to dyno all my mods!

Since the UR pulley kit seems to add about 5-8 whp, the RSX-S pulley would be less than that.
But the RSX-S pulley is steel & has the damper function still incorporated in it.
I think everyone now has enough info to make an informed decision on pulleys.

A few folks have asked why I chose a Goodyear Gatorback belt.
It was the brand name belt that my nearby autoparts store carries. Any other name brand belt would be fine also.

Drove the car around a bit more today. It still seems to rev up quicker than before!

 

[04pwptehsex]

maybe get a vid of it revving ?

 

[Mayuga]

have a extra DC5 pulley for sale.

 

[MrHeeltoe]

I'd say the possibility of making an informed choice is a little in the air still.

Why was it important for you to retain the damper?

Hi Marcus,

Since this is my wife's car & we plan to keep it for a long time (as we do all our vehicle's) I wanted a steel OEM crank pulley with the damper function so there is never an issue.
I played it safe, compromised HP for reliability & peace of mind.

With the OEM RSX steel pulley it's an install & forget about it change. Plus I learned a lot going down my "pulley quest for information journey"!!
I hope the info I gathered & shared helps others.


After all this time, I totally agree that there is no definitive evidence that eliminating the damper function on a K-series Honda engine will cause any problems.

Ok but this is where I have a problem....

These two statements completely conflict with one another and they appear a mere 7 lines away from eachother in the same post!

On one hand you are saying that there is a risk involved with the aluminum part, but on the other you are saying no evidence exists that any risk exists. It is this tendency that gets people who are uneducated on the matter afraid of the part and spread a mis-informed stigma.

People will do as you do and not as you say. If you really got the RSX part because it was cheaper and the power was not as important, I can understand that. But that isn't what you said.

Clearly you are unwilling to admit that there isn't a side-effect involved. Why?

Marcus there is no proof that UR pulleys don't cause damage either.
I have seen 2 different B-series motors with UR cranks pulleys that had excessive wear on their cranks. While its not %100 that the pulleys had anything to do with what happend there is nothing proving that they didn't cause the problem either.
Anytime you change parts aftermarket or OEM you take a risk in something going wrong.
I agree with CalgaryTSX's statement. He was trying not to bash the product your selling but he also didn't feel comfortable using a product would delete an OEM feature that he felt is important.

I pose this question why dosen't UR make their pulleys with a dampner? Then there would not be a debate & they would sell more even at a higher price they would have a wider customer base.

 

[TSX_WS]

Because K-series motors are internally balanced. BMW motors as well as old school B series and H series motors had to have dampeners. It was dangerous to run pulleys on them without harmonic dampeners, but as I said people around here ran UR pulleys for over 100k kilometers with no issues.

Thanks for your input Marcus & NC-B17A...

We're kinda going in circles here with the damper/no damper discussion.
It's not a black & white issue since there is no direct evidence either way. It's impossible for anyone to say that a damper is absolutely necessary or that it's not necessary.
All we can do is look at the large number of folks with UR & other aftermarket pulleys with no evident issues.

I don't want to influence everyone with my decision to go with the RSX-S pulley.
My situation is unique since this is my wife's car & I'm older than most on here.
I more wanted to share all the pulley info so everyone can make their own decision.
I'm definitely not bashing anyone's product.


Making pulleys with a damper really drives up the cost, as you can see from the Fluiddamper and ATI pulleys.
A harmonic damper actually has a lot of science behind it & is much more complex than a simple machined aluminum pulley.

That's all the proof I would need.

 

[CalgaryTSX]

So I got negative & positive feedback on my last post! :laugh: :laugh:


And so goes the crank damper discussion, just like the crank damper thread on K20a.org.

All I can say is that I sure don't know the answer...

 

[MrHeeltoe]

The thing is, I get a lot of customers who are unduly over-cautious. The ignorant become paranoid. It is not a bash to anyone at all, but a fact. Really, it makes my job tricky because I have to meet the demands of people who really want no compromise at all. In the end it is better then to not do anything. But in cases such as the pulley, there is almost no middle ground at all. There are those emphatically against the aluminum parts, and those who say there isn't an issue. So, who do people listen to?

 

[evan42781]

I have the NST pulleys and love them....its a great mod...esp if u pair it with a reflash!! Now grant it i haven't had them long enough to know if it will cause issues but i haven't noticed anything yet and prob never will.

The reason why im not worried about it is because I dont think Honda would spend millions of dollars on research and production to have the life of an engine depend on a piece of rubber??

 

[NC-B17A]

aww someone got butt hurt cause I posted something that didn't go along with what they think.
To the little kid that gave CalgaryTSX & I negitive rep for stating our oppions. I hope your mom knows that your on her computer lol

 

[NC-B17A]

harmonichonda please enlighten us on your theory of the problem being in the installation. Besides properly torquing the pulley to the crank & using the propper size belt what else can you do?

 

[evan42781]

tensioner its automatic...you can check it.... haven't adjusted mine since the install and its still in the perfect spot.
