    Have a choice of two pulleys, one is 120mm in diameter, the other 126. With a Ross crank pulley which wp pulley would be best for a 7000rpm engine? In other words, with a mainly circuit engine does the wp need more or less revs?

    GMH red cavitation reducing coolant being used.

    I would think the larger one with slower pump speed to reduce the risk of cavitation.
