Good afternoon everyone,

I have been searching and coming up dry on the correct belt needed for a 3.4 Whipple with a 3.5 upper pulley. I am sure it has been posted before but for some reason i am not having any luck finding it. Any help would be greatly appreciated .

Thanks

Don't quote me but I believe it's a 78-79" inch belt.

If you have a 4 piece idler kit a K080780 should work. Want to say its 78 and change. Worked on a 3.75 and 3.5 for me. Not sure if the 3.4 snout sits a little higher though.

Call Whipple? The install instructions for the 2.3l gave belt sizes for various pulleys I assume the 3.4l would be the same.

The instruction Manual i got is a generic install guide that is not specific for what supercharger you are using. From what i have read the 3.4 sits higher then the 2.3. I will give Whipple a call once they are open to get some guidance and will post back here when i have some answers.

Oh, the install guide for the 2.3 is terminator specific.

So after calling Whipple they told me that i will need to measure the pulley system after i install the supercharger to find the correct belt. I will post back here once i have installed the 3.4 with the belt that i used with my stock crank and lower.
