I have B21/23 pulleys, I'd say the ratio is close to 1:1. The water pump/fan pulley on my car is larger than the one on my B230FT car. I think the turbo cars came from the factory with smaller water pump pulleys.

Mike, did you have an electric fan on your car when you had cooling problems? Were you turning the cooling fan too slow maybe?
