belt size

Trying to estimate belt size needed for my new setup: 3.375 Upper 2lb Metco lower (8in) 4 piece Billetflow Idler Set 3.0 Alternator Pulley I am assuming I will need at least a 79" belt, possibly 80". Anyone have any input on this?

I'm getting ready for dyno day, and need to swap belt due to the oem style one shredding. The previous owner had placed this belt on, and I cannot see any markings on it that denote its size. Does anyone have suggestions for the Gates Green Belt size I should use? For the life of me I can't seem...

I know this question is beat to death but there is no belt chart that gives me the information I need. Cobrabob and malcolm where both very helpful but we still can not determine an exact size. Running a whipple 2.9 with 3.5 upper, stock cobra tensioner, "3" 90mm idlers and "1" 100mm idler...

My 03 Cobra currently has a 2.85 pulley on it. I just got a 100mm aux idler, and 3 90mm replacement pulleys (dual bearing). I plan to install tomorrow. Do I need a new belt? If so what length? I've looked at the belt charts online but I'm not really sure what i need.

With an hour or so of searching here and PM'in a few guys about my question I have got some much neeeded information but I'm still not sure exactly what belt size I need. I need the belt size for these combos on a New Style 2.2 Kenne Bell: - 3.5 / 4# - 2.9 / 4# I found a post from...

I am currently running a 3.10 upper pulley and just ordered a 4# lower and 3.2 alternator pulley and was wondering if anyone has this setup and knows the correct belt length. Thanks in Advance!
