Ok, at the risk of hearing "did you do a search" here it goes.......What size belt do I need with a BF 2.76 upper and 100mm idler (on their new bracket)? I also need to know what belt I need for a 3.4 and 100mm idler on the old bracket (for road course work). For those that want to know....yes I searched but it seems everyone is running all 4 idlers and or a lower. My car is getting tuned Friday so I need to get the belt asap.

**Beleive it or not I called BF and spoke to Ken. He could not answer the question for me which I find odd. This cannot be that uncommon of a setup and I would expect the company selling the product to know. :shrug: Doug was out of the office as well.

Thanks for your help,

My father is getting old ;-) and I was at the race track :p

Right from my website....

with the 2.76 upper and 100mm idler (on their new bracket) you need a
2.76...............74"..................4080740 + 5.... so it will be 4080745

and for the 3.4 and 100mm idler on the old bracket you need a
3.40...............75.1"...............4080750

hope this helps

Doug (loosing my mind also just not as fast) :)
