What do pulleys do for a turbo? I understand gains for a supercharger b/c its belt driven but a turbo isnt run off a belt. Is it really worth it? I know it will put extra strain on the already undersized 70A alternator.BlazinWRX1 said:Try the Vishnu Pulley, Berto and I installed it yesterday and the car feels noticeably lighter. I'm not sure how much the pulley itself is because I got the full stage 0 kit but it should be under $200 by itself.
