The chart above is definitely incorrect in regards to the macht schnell pulleys. I just installed them this past week and the crank pulley is smaller on both the power steering and alternator sides therefore the A/C has to be underdriven. The power steering pump pulley is definitely a different size than OEM so the power steering is being underdriven by a different amount than the A/C, but none the less both are underdriven.

Unfortunately I did not have a pair of calipers large enough to fit around the pulleys. Can anyone from EAS chime in with the measurements?
