Re: Belt Drive Pulleys
If it is a prototype drivetrain, go for it. You can always go back and switch to chain if you do not like it.
We used belts this year and it worked out great. They are MUCH lighter than chain and sprocket (1/6th of the weight for us) and you can get the belts in the exact lengths you need although you will still need to tension them.
We used Kevlar reinforced belts and found that they did NOT stretch noticeably in any fashion. Our tensioner was a piece of delrin turned down to the correct size, no springs, no adjustments, just the same amount of tension the entire season and we never needed to adjust them.
Belts CAN be done, do the calculations, make sure its right for you, and go for it, like i said, worst case is you go back to chain and sprocket and learn your lesson.
