underdrive pulley

[Richard]

Does anyone have one / use one of these? I was thinking of getting one for my motor when I rebuild it, I need a new one any way!

hrm going by the comments it seems like a good investment, perhaps i should look into this someday.

pretty much the best investment for the price that you can pick them up for...

just remember that you will need to change the belt as well for obvious reasons, and finding one that fits can be a little bit of a biatch...

Buy a set of belts off them, and WRITE DOWN THE PART NUMBERS That way you can get them anywhere cheaper :wink:

 

[Richard]

Belts are no problem at all, just go into Bursons or Repco and get the length and width you need, they usually have most of the sizes in stock in all the different widths. My only concern is the underdriving of the Alternator as I have 130W headlight globes and a couple of Amps with the sterio system! But when you think about it, cruising around your motor is not revving at full all the time so I guess it just means the voltage regulator will not have to work as hard when you are at full revs.

Are there any available for 4g63 ?

 

[bazeng]

yes
i have the buschur racing one,
u can now get the fluidamper (spelling)

they go for about 350USD

Just be warned these do not do what the factory one is designed for.
+ lighter
- do not help absorb harmonics made by the engine.

Use one at your own risk :twisted:

There would be better area's to speand your money on, or other parts than this.

the ones i listed have the dampening..
bushcur use rubber
fluidamper uses a fluid inside the pulley

 

[Liberoz]

JUST REMEMBER A CHEAP PART IS CHEAP FOR A REASON

and baz Im with you all the way on that purchase :twisted:
A wise investment. :twisted:

Yeah Liberoz is right, if there is no provision for dampening to replace the factory 'harmonic' balancer, vibration will eventually wear out the timing belt quicker and possibly even interfere with crank bearing wear as well. That is why it's called a 'harmonic' balancer.
