I don't know how to read them ...but from the rotrex website they all say 90k is max for them ...so I was using that as a reference for overspinning....I like the idea of boost sooner in rpm range as I don't like to redline the car .....was wanting to try to balance the pulley size to have maximum effiecincy of charger around 6800 rpm ......so I'm not sure which pulley size would be best or what the negative issues it would cause.
