On the subject of the Dual belts.. both the same.. and the one smaller one...

Racers have been doing both for a long time. Some go with a short belt.. some with two long ones.

I personally dont like the PITA of putting on a smaller belt, so I always went with the longer belts.

HOWEVER

High RPM with a stock belt, on a ported 10K+ motor=belt flying off.

SO I always get my belts from the local store, but in a wider width. I think the stock is like 12MM or something. 15? I cant remember, but I ask for the stock belt, and get the number and then up-size on the width.
I believe its a 17MM wide belt.

NOW. with dual belts.. One will be slightly longer. Realistically its almost impossible to get the exact length.

SO what I do then is put them on, TIGHT.
Drive the car around town a little.. put a half hour on it.
Then open the hood, blow off all the dust from the belts seating, and then re-tighten a little.
About 3 or 4 days later, blow the dust off, and then check tightness.
The belts will wear a lot in the first week, as they seat in the groove.

After that they will last for YEARS of high RPM abuse.

(I need to get a sig configured, and my avatard)
