Idler pullies that have failed?

[Special Blend]

Hey guys, I searched and couldn't really find the info I wanted.
For those of you that have had stock idler pullies fail how many of you have had pullies other than the lowest one?
Those with experience please step in. I am planning on getting the 3 to be safe but I just wanted to see anyways.
Later,
Ryan.

Noone has had a idler pulley other than the lowest one fail :shrug:

 

[dougwg]

thats the only one that I have heard of actually failing

 

[RJCobra]

Has anyone had the lower idler pulley fail while using the stock lower pulley?

 

[sambandit]

That's the only one I have ever seen blow up.....

Ditto. And I believe at least one of the ones I saw reported here had the stock lower. I don't have a link to that thread unfortunately so I can't be 100% sure.

I lost one up top and one below with the stock lower and 2.8" upper. I went to the BF idlers, and it has been 20K with no pulley problems since.

My lower one went, and I have the stock lower

 

[AmazonTuning]

we had one person with a stock lower that had the lower idler pulley fail..

 

[svtguy22]

I think my lower is starting to go south as well

 

[AmazonTuning]

it is just a good idea to replace them with aftermarket pulleys..it is a safety issue.

No I agree. It is better anyways because I am keeping all the stock parts from the car. I want to restore it to stock in the future so having all the factory parts in perfect shape is a plus.

You might be okay with only having an upper. I mean it is cheap insurance, but the upper isn't spinning anything else faster except for the blower rotors. I just ordered some metco 90mm idlers, but I think I might have been chancing running an 8lb with stock lower idler. Hopefully I will see them in 7-14 days. How is the car running?

I had the stock upper idler blow up, but I'm pretty sure it was due to a seized bearing.

 

[NyteByte]

Is it worth chaning the idler pulleys even if you have the stock upper blower pulley?

 

[AmazonTuning]

it cant hurt and if you dont keep listening for any chirping..that can be a sign that a bearing is failing

I totally agree. Whenever I would hear a chirping pulley, that usually meant I had less than a couple days before it would completely seize up. I always keep a spare with me on road trips!

This is only for BilletFlow Idler Pulleys!

the only one that adds belt wrap is the upper snub idler

the 2 just below that are mainly there for looks although there is a benefit of less parasitic hp loss because of the larger size and better bearings

the lower most idler replaces the stock stamped steel idlers that have been known to explode.


This is what I tell EVERYONE...not sure what other vendors tell their customers

My lower came apart last night racing a Ram Air TA. The pulley only cost $18 but the dam belt cost $45. At least I still won on motor.

I think my lower is starting to go south as well

How do you know?
