    Air Intake / Attwood Blower fan...

    I am thinking of gettign 2 attwood 4" turbo fans...my question is where is the best place to tap for a power source? I was thinking of hooking them both up to a on/off switch in the glove box. So how should I go about wiring both of them up to the switch and to a power source?

    And I was thinking about putting one mounted on the side of my intake pulling air from the left over space in the opening that isnt being taken up by the intake tube...and blowing into the engine compartment.

    For the second one I was thinking about taken the vent tube off of the cross member that helds the seats and sticking it in the hole blowing all of the engine heat out of the crossmember holes....

    Sound like a good Idea?? let me know...

    Also where is a key on power??
    I am going to use a 80mm computer cooling fan and mount it up to my rectafier to blow across the "vains" on it...and I need a key on power source so when I start my ski, the fan starts blowing to cool off the rectafier. I will get pics up shortly on my mounting ideas and all...thanks!

    Can't help you with the mounting as I don't have an RXP. I can help with the wiring though.
    I would wire them to an on/off switch so you have the ability to shut them down while the motor is still running. To do that you need to:

    Connect both negatives together and run them to the negative on the battery

    Connect both positives together and run them to one side of the switch.

    Then go from the positive on the battery to the other side of the switch, putting an inline fuse in there as close to the battery as you can.

    Please excuse my lack of artistic ability!!!

    Thanks for the help on the wiring man! I have a GTX Limited by the way, not an RXP...

    Turn the rectifier so that the fins are vertical. The heat will dissipate better that way.

    You guys may want to incorporate a relay, or 2, to control the amp draw. If not you can melt the switch.

    Get a gps so you can benchmark (extrex legend)

    Sorry but i think you are wasting your time maybe the fan on the rectifier if you have a aftermarket intake.

    I have a gps it came with the ski...

    So what does everyone think about my intake design will it work good!?

    Ok...I will mount the rectafier so the fins point upwards and have the computer fan blowing across them. The computer fan is a 120mm fan that blows 96 cfm....will that cool it enough or should I get a bigger fan to blow on them??

    WFO where can I get a relay I am not really fimiliar with them...I know that I will probably put a 15 amp fuse on the battery for the 2 fans and the switch...should that be enough?? I was going to mount the switch on the side of the glove box compartment...

    Thanks for the help guys
