03 Cobra blower belt slip

[Jay03cobra]

Just recently ive noticed my belt slipping when getting on it.. i had a gatorback belt on it and never had any issues until now. i noticed the belt either may have jumped or just been slipping so much it began to shred. i got a gates belt (not v ribbed) because the store sent me the wrong one. i said wth ill just try, it still slips around 4000rpm. Im trying to go back to a gatorback belt. any recommendations? is it the best in reguards to belt slip? part number? thank you

Billetflow's website has the correct belt sizes, depending on your pulley set up.

Are you using the 100mm pulley next to the blower pulley?

Yes I have a100mm idler and a 2.76 pulley

You need a 74" belt...with the stock lower!

+1 I actually have the same billetflow setup and have a little bit of belt slip at 15psi with a 74.5" Gatorback Poly-V belt.
I just ordered a 74" so we'll see if it eleminates what little slip I have.

Thats what i use on my car. I have a 2.76 and 100mm idler and 74in fits perfect with no slip. But ive been using a gates belt.

Yep, the 74" is what you want. The Gatorback was my favorite belt back when I had my '03 Cobra.

I have a Belt Guide on my website that covers a multitude of applications.
