C20xe crank pulley lightening

[ledpen]

I'm currently building up a c20xe for my nova, I was just wondering what the benefits of machining the double crank pulley to a single slot are, I can easily get the outer slot milled off but is it worthwhile?

They normally fail if you machine them down, Better off just buying a single V alloy one.

People only remove it because it runs the power steering which isn't there any more.

when you say fail .. do you mean explode ?

Is there much benefit in running a single one?

Bar a couple grams in weight no

No nothing that serious, they just split apart from the rubber bushing.

As Craig says, why pay to machine, you can buy a single ally one.

Benefit of single V is clearance against the chassis leg.

As said buy an alloy one, they can twist and get upset with a reduced amount of rubber holding them together. You lose the harmonic dampening properties but not the end of the world.

I can get it machined for free

its a single piece of metal tho isnt it ? .. i cowboy'd one years ago using an angle grinder, i never saw any rubber on it, unless theres various different types of 20xe pulley
