    not for sure, but if on a race only application the benefits of an electric driven water pump exceed the only the hp gained, it's nice to be able to cool down quickly after the pass in summer, especially when the rounds gets closer together.

    I used a morose add on unit for years with no issue, after 10 or 12 years it died, it's new replacement lived 20 mins, after that I bit the bullet and sprung for the high flow unit TA sells, worth every penny

    About 5 to 8 hp is used to drive the pump depending on engine rpm.
    A full electric pump on the street is fine until one scrap of rust scale or a chip of gasket material jams up the impeller and blows the fuse 25 miles from home !
    Ask me how I know this fact!
