Pullies in the AV6 do not hurt the Tranny at all. It is the Alternator, battery and Air Conditioning that will be affected. If you both were stock then Auto vs Auto you would win. Since he has taken off his catylitic converter that should hurt him off the line because he is an auto and will lose alot of torque. Good Luck!
i heard UR pulleys only underdrive like 15 percent and most of the gains are from the lighter weight
