    Post a pic. Did You get the short or long pump? Only issue I had with a Steeda water pump pulley was I had to add washers on the bolts to back them out a bit so it would spin freely.

    Send it back and get an OEM type replacement!!

    I never saw any improvement with the Stewart pump but it did seem to work OK just too expensive!!

    Neither of those fit? The stock one should but I've never tried it. Where did You get the top pulley?

    It's a 6% improvement in flow at 6,000rpm while consuming 7% less power. It will out flow the stock pump while consuming less power to run it.

    And how much time do you plan on spending in the 6000RPM zone? *Just sayin'.

    Just stating a fact. Regardless, it's an upgrade.

    Sometimes moving coolant too fast is bad also, really fast flowing coolant might not have time to pick up the heat and then release it at the radiator. Just saying....

    Any improvement with the EMP Stewart pump is not really measurable!!

    It is quite well made but a lot more expensive than OEM so save your money for a more meaningful modification!!

    No experience with the Stewart (have heard good things about them), but got bit bad on the Meziere WP and the jerks I dealt with there. Their specs on longevity are ********, and their build quality is mediocre, at least with the two I had which both failed. (They sure looked nice though! :-)). Best thing I did was put a new stock pump back in.

    A 170 stat and rear engine cooling mod were better investments for me in keeping a cool running car.
