    Re: Hayden dual electric radiator fan

    I think New Jersey is the same = but they claim its a safety issue.
    Though I've heard similar claims here.

    Re: Hayden dual electric radiator fan

    I was referring to the difference between full from 1 pump jocky to another.
    If I could pump it, I could fully top it to the same point each time.

    Re: Hayden dual electric radiator fan

    Kill switch is super easy. Just add it between the fan and the mechanism that kicks the fan on. Or in my case, the switch is on the ground side... with a relay. So, between the relay and the switch...

    So, I hadn't taken into account some of the OTHER changes that I had made pre-electric fan and how they'd effect the MPG.

    Got a bad sensor from Summit... so the fan kicks on, but doesn't turn off.
    New sensor in route.

    Re: Hayden dual electric radiator fan

    I'm guessing those are about 9" - 10" ea.
    do they all kick on at the same time?
    ...and are they noisy?

    Re: Hayden dual electric radiator fan

    ... with a good mod, that'd be a great triple fan system.
    under 10 amps to pass 3*1700 = 5,100 CFM's!

    and as a push, you could add a $h!+ton of room on the engine side
    but that small with that...

    Re: Hayden dual electric radiator fan

    spoke to the Hayden rep ~ his advice was go with a higher flow main fan and the aux fan.
    and that the push pull doesn't work in tandem. so an 800 cfm push on an 800 cfm pull will only yield 900 -...

    Re: Hayden dual electric radiator fan

    did you do the Taurus fan?
    or go with an after market (if so, what did you go with)?
    ...also, do you have them set to switch off/on by temp?
    or simply when the engine is on?

    I'm thinking of...

    Re: Hayden dual electric radiator fan

    the theory (physics myth) is that by reducing the pull on the engine associated with the mech fan = 5 - 7 Lbs of pull @ idle, you will gain an extra 3 - 6 horses or an extra couple miles per gal.

    that was a concern, but I mostly do highway travel... so I'll get a lot of air flow naturally
