here is what a friend and I did to try to resolve the intake blockage issue in deep pow. when leaning the sled hard to the intake side, my sled would bog down to 7800-7900 rpm's when snow would stick to the intake screen. my friend found belt strings in his airbox from the unfiltered bypass valve meant to open when the intake clogs. hopefully this will alleviate any more problems, and it was cheap too. the most expensive part was the SLP pre-filter material, $55 for an 18"x18" piece enough to do 10 sleds....
we pulled out the guage module and found there was a bit of space between the headlight housings and a clear path to the top of the airbox, so we took the light/guage console off to have a boo. we then took out the airbox and drilled 2 holes, one behind the other with a hole saw right over 2 moulding posts on the top (they are gone now). the airbox is made from thick plastic, about 3/16", then we threaded the holes to accept 2 male to male threaded plastic nipples. we siliconed the threads and screwed them in until they bottomed out on the "nut" and then put a bead of silicone around the installed nipple, leaving the top threads exposed.
next step was to make 2 holes in the top of the console just behind the windshield, large enough to fit a rubber grommet used for 2" clearance lights in automotive applications.
we then used a plastic female to female threaded pipe fitting cut in half, with a threaded hose nipple screwed into the end to accept a plastic 1-1/4" hose. from the underside of the console, we pushed the female fitting up into the installed grommet with a piece of the SLP material on top of it until it was flush with the top of the grommet.
we then mounted the 1-1/4" plastic pipe to the nipples on the airbox, leaving a lot of length to be trimmed off later.
then the airbox was reinstalled in the sled, and the console fitted loosely over top to determine the correct length for the hoses to attach to the nipples on the underside. once we cut the hoses and attached them, we routed the hoses in between the headlights and bolted it back together.
slapped the guage pod back in, put everything together and it looks pretty good (for a couple of rednecks). the air will flow into the box before all the sensors, so there should be no grief with the DPM. heard from a few guys that had put flow rites in the back of the airbox were feeling a lack of throttle response, maybe due to the air coming in not flowing past the upper sensor in the airbox.
other than the SLP filter screen, it was under $20 bucks to do 2 sleds. rode Hasler yesterday in 3 plus feet of fresh snow and didn't bog down at all, but it was very cold and the snow was quite fine. hoping to try it out once it warms up a bit and the snow is a bit more set up and restrictive.
