Hi Guys,

I am currently running a Saleen Supercharger with a 3.6 pulley and use a 107.5" serpentine belt...

All other pulleys are stock sizes....

Planning on changing to a 3.4 pulley and V10 oversize water pump pulley...

All other stock pulleys will not be changed....

What serpentine belt size will I need for this setup???

Can I keep the 107.5" size belt???

Your advise and comments arre greatly appreciated... Dave

Will depend on how much room your tensioner has to move out and take up slack. Buy a 106.5" belt, try the stock one first, and if its too long and the tensioner cannot take up the slack, go with the smaller belt. If the 107.5 one works, return the other one.
