    rear air intake..pics

    this is my home-made rear intake...

    1x 4"-3" silicone 45 degree reducer from siliconeintakes.com
    1x 4" dia alum. 4" length tube from pep boys
    1x 4" dia alum 45 degree elbow from pep boys
    an 8" length of 4" dia flex hose - had it lying around

    the 2 45 degree elbows allow you to get great alignment. the flex hose isnt scrunched up like it was before. everything is very staright and smooth. no turbulance, smooth bore.

    i took the 4" length of 4" dia alum tube and shoved it down the rear vent. used a heat gun to heat up the bottom of the vent so it could contour to the round shape of the tube.

    i cut a pretty decent slant in the rear vent to help out alignment. the way the vent fit from the factory, it leaned toward the resonator side of the ski. i moded mine so it is slanted the opposite way and sealed the top, where the vent meets the seat cowling with silicone so there are no air leaks.

    thanks!

    i used an old riva one (that came with the old power filter kits) i had lying around. i just cut a piece off and put 2 screws to hold it in place. it was either this or the $150 riva "pro series" prefilter, which is a bit steep for me. outerwears.com can make you one for a few bucks aswell.

    and i put 2x 2.5" flow rites in the grab bar to get some more air...

    4inch supercharger adapter

    i wonder if a 4 inch adapter from RXPblast would help any


    instead of the :1x 4"-3" silicone 45 degree reducer from siliconeintakes.com - 20

    I have both items you listed. Either one will work fine since it's going into a 2 3/4" SC hole anyway. But, I found the RXPBlast adapter to be a better fit on the 4" hose than the 4-3" reducer.

    I hope it doesn't choke the intake like I did mine. Is the outerwear from the power filter the same density as the rear intake setup? Try a run with it on & off & see if you get a 300 rpm increase.
