custom ud pulley

[sam c.]

Thanks for the reply, Jake. The smaller the diameter, the more the components are under-driven and the less parasitic losses. That was really my question... has any research been done to see how small the pulleys can be made without having an adverse affect on cooling and charging? (This would be for a strictly street driven car interested in the performance gains that would not be held to any rule mandated pulley size).

Thanks!
