Does anyone know if the 2.9 Whipple belt sizes should be the same as the 2.3? I've searched to no avail, and couldn't come up with any answers. I'm doing a 2.9, and will have the stock 3.5 pulley for street, and the 3.2 for my race tune. I have the 4 piece BF idlers w/ snub idler, stock lower & alt. pulleys.. I also have the Whipple aux adj. idler that I can replace the snub with if need be. Does anyone know what size belts I would need? I've looked on cobrabobs list but it doesn't show my setup. Any help will be appreciated! :beer:
