Number of Idlers

[vbguy01]

Is there really a big difference between the performance of having one 100mm idler as opposed to 4 idlers? I've noticed quite a few sigs with just a 100mm with no slipping issues. Bottom line...are four better than one?
:??:

If you want to run 3.4" or 3.1" you should be ok without an aux. idler but I have seen HP gains(around 8rwhp) when adding an idler to a 3.4".

If you are going to run a 2.93" or 2.76" I would strongly suggest getting an aux. idler setup.

How many:

All you really need is the one extra idler (100mm) and the bracket that it mounts to.

I have MANY customers that get the one aux idler pulley plus 2 or 3 more to dress up their engine compartments as my Idler Pulleys look much better then the stock ones.

Another reason to change out all your stock idlers for mine is that there has been several reports of the stock OEM idler pulleys (for lack of a better term) exploding under high Load/RPM. But I'm not saying this happens alot. Just something to be aware of, thats all.

Hope this helps you out

Good post Doug. I had your 3-piece set myself, but it was only for the bling factor. One is all you really need.
