    Cold air to hull

    Has any one tried using "cold air guns" to add cold air to the in side of the hull?
    Back in WWII they used cold air vortex tubes to make VERY cold air on some models of fighter aircraft, because the large inline engines would over heat the last cylinders. It is winter up here, but I have been thinking about trying this by holding one out the window of my car when it gets warmer.
    You guys Know what I am talking about ? Right?

    What if you turned your front bucket into a frozen honeycomb using those little blue freezable thingamjigs and route all of the incoming air thru them?
    Of course with the warm air coming into contact with the cold surface of the honeycomb there will be condensation.
    I am an commercial/industrial insulation distributor, if i can be of any help just let me know.

    Dry ice in the front bucket, marine 4" blower, tubing....voila'! Cold air flowing in the engine compartment.

    Bo Dupriest did this in 90's on his race skis..whether it worked great or not?

    I did a "ram air" setup on my ski by hacking the stock hood. Back to back tests between that and stuffing a towel in the hole showed absolutely no gain in rpm or speed. Go figure.

    Me too! I had an insulated double ram air set-up with a TORNADO at the airbox. TOTAL WASTE OF TIME. But i guess thats how we learn what works and what don't.

    now that would be the question?
    because cold air we all know we gain rpms,,( in the fall we do) but how much would we need to get more dence air (cold air)?
