    One of my near future mods is setting up a ram air/cold air induction setup for my TPI input............if you haven't seen the front of a TPI, pics on the site below under TPI 406 motor page...........I want something that if possible takes the cold air from a source not in the front of the truck but also not susceptible to water splashing into the intake.

    Any ideas you guys have seen? I saw TPI86's but want more options before I decide what to do.

    Perfect world? - steel 2" cowl induction hood sucking the cold air from the cowl.........[​IMG]

    splashing water huh? on the windshiled too? cowl induction takes in from base of windshield, so don't use a NASCAR style cowl intake set up system. maybe a '79 TransAm shaker style rear facing intake that doesn't go all the way to windshield?

    I've been kicking this issue around in my head off &amp; on as part of my future planning (TPI 383 and steel cowl hood on my wish list)...

    If you go with a cowl induction hood, a lip of some sort (like a dam) at the entrance to the scoop should probably divert most of the water on the hood surface around the opening. Making the engine-side air intake enter the airbox at mid-height and having a couple drain holes at the low points should take care of the rest.
    The airbox I refer to is the unknown quantity in all this. I haven't thought of a good way to get the air from the back of the hood to the front of the motor yet, but I think it will involve some sort of airbox.

    Maybe we both need to get a couple good looks at the new Camaros and Firebirds with the hood scoops to see what the factory did about the water-ingestion issue... Try to find a couple ideas there.

    If at first you don't succeed, failure may be your style...
