Whipple 3.4 10% OD belt size

[STTOCK]

Buttoning up my Whipple 3.4 install and I need a belt. The car has an ATI 10% OD Crank, Thump Tensioner, 90mm idler (can switch back to stock), and a 3.75" blower pulley. I tried searching and found similar setups, but no exact setups that were the same as mine. I'm thinking an 87.9 but I want to be sure before I order. Whipple could not supply me with the answer.

Yep. 87.9" is what you'll need. I have them in HD Green in stock if you need one.

Thanks a lot Van. Any chance you could get it in blue?

I tried to have them made and Gates said no. That was six months ago. Green is it. I can get it in black too though.
