i was reading the forums awhile back and someone asked something bout if they got a smaller pulley would it mess anything up as in needing a smaller belt or being to small of a pulley to power everything, my quesiton is this i dont know much about all the pulleys and all that, but on rpmoutlet.com they have the 42% reduction pulley, if i got that, would i have to get another belt? like a shorter one?
