    RXT Air box....cool air in abundance

    This may not be a new idea but I thought the shots were worth a look and someone may wish to comment on the for and againsts of it.
    This is the Rad 4 Racing 4 inch air intake adaptor to convert the front bin to a dedicated cold air box. Of course the hood is vented to allow air in and the bung is removed from the bottom of the bin to allow water out.
    It is all anodized ali and the adaptor with the barb on is to run the breather back in to the air intake before the SC. Everyone will have an opinion on that with the pro's and con's but we do it to maintain vac on the crankcases......the downside is cleaning out the intercooler between offshore rounds.
    This ski is set up for the New Zealand Winter Enduro Season which kicks off next weekend. I will post pics of that then.

    Cheers

    look for jammer's setup, same idea but i think actually his has less chance of water gettin onto the filter/into the intake...
    otherwise this looks very good high quality setup.
    what diameter hose are you running?
    what type of reducer you using at the sc?

    Kevin, several here have looked at using the front bin as an air box. How is the hood vented sufficently to allow air in without water??

    More pics coming

    I will post some more pics on Monday so you can see what we were up too. The system is four inch to the mouth of the SC.

    I had the same question about venting the hood without water intrusion. I previously posted a mod for allowing fresh air in using an Ultra250X vent (duct) tube.

    I am so glad you posted this again. This will be done on my RXT today.

    With the 07 RXT not having the wall it makes it a little easier coming up with more sources for air..

    What about the underside of the hood (the black plastic assembly. Looking at it if you drilled a couple of holes right above the storage container and a couple of holes on the storage containerseems like there is a path for cool air.

    holes

    Yes mate, the holes in the hood let the air come in from the highest protected point. We have no real water issues and in fact our filter element is paper on this one which never gets saturated so I guess that is the best tell tale.

    Larry,
    Open up your hood.
    The black piece on the underside of hte hood seems to be a pretty good source of cooler dry air.
    The flat spot right above the sotrage bin seems to be ideal for a few good size holes. The drilling some holes in the storage bin and I think the intake of air could be almost doubled.

    Holes in the hood inner

    Your on the money with the holes in the flat under the hood as in our pics. The boost gauge in the mirror is not new but the mount plates are now avail in black anodizing and they fit in an air mail envelope.
