have you got the pulley on yet? would like to hear how it works for you?......TheMoparConnection said:My Viper tech had an extra underdrive pulley and gave it to me. I'm still waiting for my belt which should be in by middle of next week. I'm gonna try and install it before the dyno and track day next saturday and we'll see if there's any improvement. Will keep all posted! Anybody else use one? Have experience with one on these motors?
