Click the link and read the last sentence of the paragraph under "Pulleys" It sums up my feelings about underdrive pulleys. I know a lot of you will disagree with me, but i've just seen to much research saying the rewards are minimal at best .. Thats just my opinion.
By the way I consider Stewarts opinions on cooling systems and its water pumps to be second to none.
