Belt size

[EddieCuse]

Hello All!!

I know the typical answer is to use a string lol. But my combo is recommended from many of you on this site, so I figured you’d know off hand

3” alternator pulley
Metco idlers with the additional pulley
2.90 supercharger pulley

Everything else is stock


Thanks in Advance

There are 90mm and 100mm metco idlers...you may have a combination of both or exclusively one size.....belt size will vary based on that....

You should always string it....it take 5min....why guess?

The tensioner will accomodate for a slight difference as far as belt size, but the string method is recommended. But, if another person has the exact same configuration, including idler sizes, then just buy the same size belt.

@EddieCuse, post a follow-up when you install the belt to confirm it fits perfectly. That might help others in the future who have the same question and end up in this thread.

True. I just looked it up. There are a couple different idler pulley sizes depending on the set you order.

I’ll list all my purchases and the belt size that ends up working for me
