    belt length for revised novi 1000 with 8" crank pulley

    wondering what the length of the acessory belt is with an underdriven crank with an 8" crank pulley, the new revised novi, I know the size of the blower belt, not sure if I can use the stock belt with the new pulley

    89" If all other acc. pullies are stock sized.......88.5 would be better if you cab get it on there. this would pull the belt up away from the water pump pulley since the tensioner pushes it real close.......i recommend getting both & using the one that works best with your application..........

    Are you talking about the next size smaller blower pulley? Sorry, you weren't specific.......ASP sells those as well. Don't think anyone has voided their warrenty yet to find out the results yet though, if you decide to change yours please let us know how it turns out =)

    no the crank pulley that goes to the supercharger is 8" I left the blower pulley alone. And the crank part of the pulley for the accessories is smaller then stock. The 8" pulley is a 1 piece for the revised version of the novi 1000
