I don't think anyone is denying the fact that having the water pump pulley is beneficial or a "smart" move. The question in debate is whether or not it is "absolutely necessary". Being that many people have ran the UR without a OD pulley as Broke has said, I think this proves that it is not "absolutely necessary". But, when I do personally do get a UR pulley, I will also get OD pulley for peace of mind.
