I just installed my comptech supercharger with AC, but the problem is the belt will not stay on the charger when driving in Vetc. has any on else had this problem. The belt does not pop off every time but 1 out of 5 times it does. need help

 

Have you tightened the belt? It should be tightened a few hundred miles after install.

 

Are all the pulleys lined up? You may have one not in line with the others. The belt may also be too loose or too tight.

 

I'd bet on to loose.

 

Mabe my belt is the wrong size, what brand and size(belt #) is used on stock comptech with AC set up. thanks

 

I heard gatorback belt, but what size with stock pulley
