Idler pulley size?

[Motorhead350]

I am ordering one from another source instead of Procharger. Does anyone know the right size?

I would call Procharger, but I cannot stand those people.

I had the options of 2.8 3.0 and 3.4 I think.

Already googled it, but there are so many setups I could not get a clear answer.

Idler or SC pulley? You could always measure what you have.

52mm he says.

So annoyed.

Oh well, keep moving.

I didnt know what they measured by, thats why I asked.

The one that answered the phone gave me s/c sizes... not what I was asking about.
