Which Idlers Should I Order?

[blownfox]

Hi All,

I just purchased my first 03 Cobra and it should be arriving in the next day or two! It is a stock blower car with a 2.76" BF upper with idler. I would like to replace the three factory SC idlers. Trying to see if there is a benefit going with dual ball bearing versus the BF idlers. I won't order anything until the car is here but I am creating a list. They are mostly suspension and cooling mods!

I personally went metco dual bearing.

I went with BF to match my upper pulley. Been running the idlers for couple thousand miles with no problems. I would say the belt is more important than the idlers. I have a GATES HD belt. Make sure you buy the part # with "HD" at the end.

Metco

Metco hard anodized dual bearing.

And if you can wait until the big Christmas sales you should be able to find them for up to 20% off.

I disagree. When my stock idler grenaded it shredded my green HD gates belt like it was made of tissue paper. 4 years later I'm still picking out tiny pieces of belt from random spots in the cars engine bay. I upgraded to the dual bearing Metco setup. 3 90's and 1 100mm I think. Or is the the other way around?

I should have gone with Metco dual, but I was cheap.
Single bearing idler will have shorter bearing life. replaced bearings after 15k miles.

Edit: Holy smokes they are expensive now @#$!

Metco here, and I would go the the Gatorback belt, I never like the Gates Green belt, my car would just eat them like candy.

This! Long term, you'll be very happy with the Metco idlers. Great looking, too.

Is it better to get 3x 90mm and 1x 100 mm idler or the 3x 100 mm and 1x 90mm idler set?

I did metco dual bearings last month... The added stability is worth the piece of mind. Plus I'm 600 plus hp I want it as strong as possible. I did all 90 mm and the auxiliary sc pully was already on the car I will be switching to metco shortly.

Look at the tensoner plate as well it's cheap and a good mod.
Metco makes it

I've often wondered this too. I have 3x90 and my aux/snub is a 100, which seems to be an odd combination when looking at the sets that are offered.

This is my understanding. It depends on the size of your upper blower pulley. Here is an explanation from my Terminator FAQs. CLICK HERE.
