thanks for the input.. i know, i have no issue with cooling either, i've had my 250,000k mile 350 still get 175 degrees and no higher with a mechanical setup and aluminum radiator, i basically just wanted a setup that wouldnt drag the motor and free some hp. thats my only intent on finding out how reliable and efficient an electric pump is. i've seen a claim by weiland i think, or mezierre, they mentioned "suitable for street use, average life expectacy of 2500hrs. thats around 104 days of constant driving, and assuming you drove a quarter of a day each day total.. or 6 hours (which is how much i drive), you'd end up with roughly 417 days of use. this puts me about a month over a years worth of use. mechanical pumps usually last a lot longer but looking at the facts you'd have to decided what you're willing to compromise... would you pay $130 (cheapest) approx. every year for an electric pump? maybe not, but i still have yet to find the best pump.
