[QUOTE="rdsnk46, post: 12300078, member: 28757"] Innovators West claims both the 10% and 15% lowers are lighter than stock crank pulley assy. Thus the weight reducton of the balancer assy is the reason for the increased TQ over the upper pulley. As far as the larger diameter 10% and 15% rotating mass causing more drag due to being further from the center of the crank seems to make sense to me. I dont think that the upper pulleys slipping has anything to do with seeing upwards of 50 rwtq(IW 10% lower 4psi) over the same upper ratio pulley matched boost increase(4 psi). The contact info is at the top of the page for more information.
