no joke...about the impact gun. i'm not bs'n....i just think since the car had a lot more miles it the bolt was stuck due to the heat....hopefully on my k20 that won't be the case

Your engine wont last as long with a crank pulley like that one. The stock ones have a dampener inside them to reduce all the vibration. If you plan on keeping your car for a long time I wouldn't get a crank pulley

is this true..?

Word man, same here with my 98 CL 3.0. I used a breaker bar and a floor jack...Jesus Christ on a popsicle stick that thing was a bitch!!! I also used the Honda tool to hold the pulley in place...

This is the only thing preventing me from getting these...do you know how much of a gain you would get on a turbo car...

im not going to go on a rant about aftermarket crank pulleys. (you can search for that)

nice work and thanks for sharing with us

Can someone who is more knowledgeable than I comment on this. I have seen endless discussions on this issue and it never gets resolved. Also the issue of harmonic balancers...

if you do a quick search on pulleys, its been beaten up.

not worth the money,labor, and risk for the hp. my $.02

Oh yes, Blu this is the one issue that me and you disagree on..I remember now...lol...well, we can't all agree on everything...I probably wont do them as I'm gonna go FI eventually anyway (probably S/C) and I dont think these would work with an S/C due to the pulley issues...

you kmay want to double check on that...last time i took a honda pulley off it was a solid cast piece....no rubber dampener in there or harmonic balancer. those are for V8....not inline 4s

IIRC the stock crank pulley doubles as a harmonic balancer/dampener. It is weighted specifically for the engine. And i highly doubt the pulley is "cast" steel.

Every engine has some sort of crank balance, they're not just for "v8's"

from what Mike from NST told me, the harmonic dampener is not necessary, and a lot of the dampening and balance comes from the belt anyways. I think the harmonic dampener problem is a myth, since plenty of people swear by pulleys and havent reported many problems. Every "problem" someone has come up with has been a "he said she said I heard" type of deal, but nobody saying "omg my engine blew up because of the pulley"

Of course the company is gunna tell you there is no problem...they want you to buy their product!!!

but of course like I said, I haven't seen anyone here post negatively about pulleys that actually had them. The only nay-sayers are speculators... i think if the harmonic balancer or whatever was a HUGE problem, a lot of people that have bought these kits (UR doesnt have it either, i believe) would have had problems.

Please don't spread internet hearsay. The stock crank pulley is not a harmonic dampener/balancer. Honda's engines are internally balanced. The stock crank pulley has an elastomer (rubber ring) to reduce Noise Vibration Harshness. So replacing it with a UR crank pulley is fine. However, if you are pushing 3-4 times your stock HP and are revving the car 2-3k over your stock redline you would need an aftermarket harmonic balancer which some companies make. At this amount of HP and at these revs you create different frequencies that even the stock crank pulley doesn't know what to do with. In fact, UR is releasing a harmonic dampener for B and D series engines and other highly modded engines, but they are set up to deal with those higher revs (and thus different frequencies) and the torsional vibrations associated with those circumstances. But for all of us who aren't pushing that kind of hp ( I push almost 2.5 times my stock HP and I run the pulleys myself without a problem; everything in my motor looked good when I pulled it apart) then the UR pulley is a great mod that helps the car rev out quicker. And there are many many people who have been running the crank pulley for over 100k without a single problem.

The reason that some B and D series guys frowned on the UR crank pulleys is b/c some of these guys were pushing 3-4 times the stock HP and were revving the car 2-3k beyond the stock rev limit. The stock crank pulley isn't a harmonic balancer; it just has

liuh · 12-26-2006, 08:02 PM

bam! ^^ sounds good.

but lets not be biased, i'm sure this same information applies to the NST pulleys as well. Is UR going to make a R18 kit?

8civic · 12-26-2006, 11:47 PM

Most factory pulleys have a very thin rubber band sandwiched into their steel pulleys to reduce vibrations and noise.

The anti pulley scientists claim that if you remove this rubber piece your engine will fail after long term use (something like 150,000 miles or more.) These guys swear up and down that aftermarket pulleys are the work of the devil and will tear your engine into pieces. Their evidence is usually theories and formulas backed up by internet heresay and "he said, she said."

Then there are others who have actually used pulleys for years and have never had issues. These people usually outnumber the first group. I have been using NST pulleys for the past few years on several cars with no problems of any kind.

Third, there are the pulley builders who tell people that their products are safe if installed properly and won't harm your engine if you know how to maintain it properly. They sponsor cars and test their own cars. Ofcourse they are full of crap because they are only trying to sell us stuff. We shouldn't listen to them

Here are a couple of cars listed on the NST site. Would these guys really put weak sauce products on their own race cars if they knew their ish would blow up in front of their fans when they go to big events?

BLU BY U · 12-27-2006, 07:30 AM

i dont see engine bay pictures ^^^ and most (if not all) high hp hondas never have any type of aftermarket pulley on them.
