lightweight crank pully

[enigma]

could you use a solid lightweight crank pulley on a 4ag? i was thinking of trying to make one on a lathe but im not sure if you need the "rubber" bit in between the pulley and the centre piece. or if this is not needed

Technically, the pulley is the harmonic balancer. I have seen the SS works aluminium pulley and it is not modified for balance. I run a ringle row machined 4AG pulley and have had no balance issue.

The result of this is that I will be making a smaller pulley in place of bigger alt and water pump pulleys.

Also look at the T3 ones. No balance/machine holes last time I looked.

[enigma]

so are the t3 ones a single solid piece or two piece like the standard one?

[jaz_ae86]

pic are there

[enigma]

they look single. thanks for that

you could machine down a 16v rwd pulley and it would be ~1/2 the original weight

[jaz_ae86]

They are not half the weight as the rear section is almost solid- go and look at the pulley.

And in fact, the RWD pulley has a smaller pulley size for the front section.

Hence why I put a '~' sign to indicate its approximation...though I agree with you its probably even 1/3 but thats still decent amount relative to itself. At least that way, the dampening rubber can be retained.

i have a single row lightweight rwd pulley that i may sell for around the $150 mark if anyone is interested in it...have decided that standard RWD pulley is a better option for me...pm me for further info if ur interested

i have been on the toymods website and this is what a bloke is thinking of doing a group buy for these are a custom fully alloy and are very good for high reeving/power engines im thinking of getting 1
