Need a belt fast so I can tune!

[Stang2WRX]

Hey guys, im scheduled to take my car to the dyno, but after finishing the build, I realized whipple belt charts were way off... the stock belt comes nowhere near fitting.

Any suggestions on where i could find a 76-77" belt?

I can sympathize, 3 trips to the auto supply yesterday and some very helpful counter guys finally got me the right belt.
I searched here and saw an Amazon response to a poster with a Whipple with a 3.5 and a 4lb lower and they reccomended a 78". Well that was way too short. I forgot to add the 4lb alt pulley and effect of the HBH/RR blower spacer.
Went back got an 81", still way to short. Last one they had before 90" was 83" and it ended up fitting.

Of course now my whipple is hitting the underside of the hood.. :xpl:

my combo;

Whipple w/3.5"
Metco 4lb lower
Metco 2-4lb alt pulley
HBH/RR spacer

I used a Gates Green Line 83" 8rib belt. It leaves enough room on the tensioner for the 3.25 pulley, maybe even the 3.00"

Probably need a bigger belt for the 8lb ring I have too.

Your local NAPA store should have one. Autozone might as well.
