i'm looking at buying this:

http://cgi.ebay.com/ebaymotors...82287

has anyone had experience with this or similar pulley and is there a noticable difference?

i already have no ac and ps so i figured this would help even more....

thanks for your time and input

 

Basically just reduces the rotating mass on the crank... not something i would buy but its definantly not a worth-less mod. i would imagine the only noticeable difference is being able to rev up your motor more quickly

 

It is like putting a lighter flywheel in, but on the other side of the crank.

The weight difference won't be as drastic as a 18 lb to 9 lb flywheel, but you will see some better throttle response out of it.

 

anyone else have one of these?

 

No, waste of money IMO.
I have also heard of these things destroying ppls engines.

There is a lot of debate about this. It does eleminate the harmonic balancer, and this can cause problems. Now I have heard some people say after 10,000mi there is a good chane you are going to spin a bearing, but I know of other guys that say they have run them with no problems.

There was alos someone here on HT that was taking your stock pulley and shave off the accessory belts, this keeps the balance, and drops some weight

this was me i have a ITR crank pulley with all the accesories shaven off like the civic N!, but retains the rubber dampener in it. stock itr pulley wieghts 5.XX lbs and after the shaven its around 2.3lbs or so.

ITS FORSALE - getting rid of it for a fluidampener.

 

it says
"Fully balanced from Honda and weighs only 1.8 LBS (Stock one is 10 lbs). "
does this mean that it has harmonic balancing? what is that anyways?

 

The harmonic balance is a piece built into the pulley that soaks up some vibration from the crank and pully being out of perfect balance. Just about everycar out there has one.

Even though the new pully is balanced, it does not make up for the crank not being in perfect balance. I assume some people have good luck just do to have a good balance in both the pulley and the crank, others might be off a little and hece they spin a bearing.

This also explains the whole balnce and blueprint when you hear about fully built race motors,

 

i would check up on some threads about civic n1 crank pulley. they have been known to bust oil pump gears.

see the middle black ring? thats the dampener in stock pulleys. this looks just like mine but its black.

 

Don't buy the N1 - read this:
http://www.dinancars.com/whitepapersFile.asp?ID=5

Just so you know Racermech - it's not a harmonic balancer - it's actually a harmonic damper, since it's not balancing harmonics, but rather dampening them by absorbing the vibrations of the rotating crank.

 

alright, so, are there any aftermarket crank pullies that have a harmonic damper?

our cars dont have harmonic balancers; they have dampeners.

ANYway...
if you're worried about that, inlinefour.com has a pully similar to the ctr n1 pulley with a dampener...
http://www.inlinefour.com/infourn1encr.html

 

the one on inlinefour is the same one i posted and the same one im selling. the pulley is just a modified stock one.

FWIW: the itr crank pulley is the smallest and lightest of all the bseries except the N1 pulley.

 

I have a underdriven crank pulley. It has lasted a long time on my engine. It made a noticable difference throughout the powerband. However Im going to be boosted soon so im putting the stock one back on. The one I have is not a damper. No noticable negative effects I can tell have been done to the engine.

have your stock one milled down, and save your motor.

how would i have the stock one milled down? wouldn't that not be balanced??

...and balanced.

 

I had the CTR pulley on my b16 for a long time, and I didn't have any problems. I did feel a little difference in power. It helped a little bit. I needed some money, so I sold it, so I don't have it anymore. I was leaning towards buying an aftermarket one like Unorthodox racing's pulley, but I heard so many horror stories about pulleys. So I got the CTR pulley, cause it is an OEM honda part, so I figured being OEM, it wouldn't destroy my crank or oil pump.

you should check the archives about the use of N1 pulleys. most people have luck and nothing happens to their motors while others have the oil pump gear shatter.

yup still selling mine. its a bseries ITR one that was modified.

 

I got the stock one on there now. I'm not giving my car another reason to break down on me. All I need is my motor to take a **** on me, when I'm out of work, and have no money. Broken bones suck ***!!

 

i would never run that pully
its been know to destroy oil pumps and destroy motors. its not worth it
you should only run 2 pullies.
1 stock non ctr
2 fluidampener
