I am in the process of installing a new Vortech on my 90 Mustang. (The 8-10 psi kit) I cannot for the life of me get the factory belt back on.
It appears like a need a couple more inches....

I have a 3g alternator, could that cause a problem.

Has anybody had this problem before. I have checked and re-checked to make sure that I have installed everything correctly.

Is it possible a get a slightly longer belt? What is the factory length?

Thanks in advance.

That would be cool. The manual from Vortech said it would fit, but there is no way that I can get it on.

Thanks for checking the belt out....

Did you have the 3G on before you did the supercharger?? I had to have a longer belt as well because of my 3G alternator

I put the 3g on at the same time as I did the supercharger but it appears to have the same diameter pulley. It is a PA performance one and I did my buddies just like it (no supercharger) and he didn't need a new belt?

You have what size belt you went with? Factory is a 90.5" 6 rib, correct?

Belt

I had to use a 922k6 belt and it fits perfectly. That is 92.2 inches with a 6 rib. I think the stock one uses a 90.5 inch 6 rib. Hope this helps.
