- Thread starter valco
- Start date
I agree in dez race conditions the ump is the way go. Do u guys think that a foam filter will be adequite is recreational ridiing in the dez?
I try and leave a good gap between me and the car/bike in front of me. I don't like eating dirt no more than my filter.

For sure! A properly oiled foam is great. Just keep an eye on it and keep it clean. The oil is so sticky, it can get dirty pretty quick it is really dusty. I run a oiled foam on my R1. Foam is much superior to oiled gauze for desert IMO.
I posted this on the other thread, but basically its like this:
Oiled Gauze: Best Flow-Worst Filtration
Oiled Foam: Good Flow-Good Filtration
Paper Filter: Good Flow-Great Filtration
Paper Filter in a Canister (like UMP or Donaldson): Least Flow-Best Filtration
The two Paper filter setups will go the longest between service because the dirt doesnt stick to the element, like a oiled setup.
Its all just what your looking for. Max HP, use a Oiled Gauze (K&N). And if your willing to give up some HP for better filtration, start making your way down the list.
Also, note, Paper filters do the worst when they get wet, of all of them, so take that into consideration if your doing water crossings or something.

those motors did not blow because of the filters. I do not even think Joey had a k& N on his old motor that blew up at glamis, it was stock foam.
you can see daylight through a paper filter too, when it is clean.
back that up with data instead of assuming. I have yet to get anything into the intake of my rhino or vw with k&N filters WITH outwears.
paper has been the best filtration no doubt. K&N rules performance
I don't have technical data. I suck, I am going to install K&N filters on everything. Hahahah.
K&N filter with outerwears..... I have never had problems...
just clean it and oil it before evry ride...
ive never seen dust or sand inside.... best performance..
Of course all my knowledge is from first hand experience. No data here either. But I did get alot of dust in the intake past the filter on my turbo buggy, but I believe thats exaggerated by the turbo. I also done dune, pure desert, so more dust, I think. I just dont trust the K&Ns for an extended time in dusty conditions any more, plus they will clog full the first real silt bed you run through desert racing.
I dont know how many miles Ive put on my rhino with the UMP, but Ive never cleaned or changed the filter. When I swapped it from my race rhino to my 4 seater, the filter still looked brand new. Ill take it out and tap off any buildup, lets say, in 8 months.
But I did swap over to a K&N on my 660, for max HP once i started racing short course. Not enough dust to worry about running a UMP there.

Just checked my K&N and no dust in the intake....I was running a K&N on my stocker when it popped and it had no dust in it either. the motor was not sanded. just cooked...lol K&N are only as good as your maintenance.
My opinion is from my personal experiences with using different air cleaners on quads & MX bikes. Clamp on K&N vs. clamp on dual stage oiled foam. On several different machines I found sand past the filter with the K&N filters. Once I swapped these to the foam I never found this again. My .02 FWIW.
Does anyone have the installation instructions for the UMP on a 660 Rhino they could email or fax me? I purchased a used setup and having some problems with the front bracket, bottom of the canister hitting the neutral safety switch and allaround clearance issues. I have tried to contact UMP, no answer and wont return my calls.
Thanks!
Thanks!
