No snow so I started cutting.... IQ intake solution!?!?

[dub]

If we don't get some snow soon there will be nothing left of my sled...LOL

Here is what I did:

I removed the POS water, I mean air horn intake that I purchased form a certian un-named aftermarket Co. and added a large K&N cone filter simillar to another aftermarket intake system. I then took the entire headlight assy and cut out the entire bezzel leaving the lense only! I then bought some Frog Skinz pre filter and drilled holes in the lense and covered them up for intake holes!

Now for the headlight I took the stock center "cyclops" mount and bolted it in the stock realative location to the lense and added the high beam center light to it. We started it up and put a paper towel in front of the headlight and wicked the throttle and it pulls it right in!!

What do you think? Should save some weight, stop the water ingesting issue and breath better! Have an Outter wear on order..

seems like that'll still plug up with powder like the dash vents do. should try some Powder Valves from a certain unnamed aftermarket company.

There are many other vents on the other side from certian unnamed AM companies!

That's what I have been brewing in my head too. The other unnamed company that sells a very similar product for WAY too much bread will NOT be getting my money.

How does the K&N stay in there? I was thinking 4" alum. tubing welded to a plate that could screw/rivet to the air box, or screw the plate to the hood with the K&N burried up behind the headlight and just run the foam ring between it and the air box.

Nice job!!! Should work great!

Nice work! I've been toying with that same exact idea, even bought the k&n filter already and prefilt already.

 

[helmethair]

can you post a pic of the underside of the hood? my sled wants to be lighter

I used a piece of 3.5 OD aluminum tube welded to a 6" diameter plate, the tube actually sits 15deg from 90 on the plate (so 75deg).

For the under side I actually just cut aout the existing entire hole that was there, it's like a whole with a semi straight endge on the LH side (where the intake bolts now).

The foam donut that came stock with the sled stretched right over the base of the K&N and makes a great seal.

The filter I used is a 5" base x 3.5" top x 4" long (#RU-2990). This filter will not fit with the headlight bezel in tact!

I did the same thing with the air filter. I also put a pre filter over the air filter to prevent snow from clogging the filter. works good. poor design from polaris leaving it wide open to inhale needles an small debre.

I agree, the Poo design leaves a lot to be desired, but this seems a little too restrictive. I'd be curious to know if your max rpms drop a little or not. Otherwise very cool! Nice work btw.

You know its hard to say about the rpms. In 08 my sled ran 8250 rpms on hard pulls, but since its had the 09 and 010 rebuilds its never been the same. it only pulls 7900-8000 rpms right now. Im trying to get the clutching figured out.

Please explain how this seems more restrictive?

Don't get all sensitive man, it just seems to me going through an air filter and maybe through a slightly smaller hole has to affect airflow somehow. K&N obviously flow MORE air than a conventional air filter, but it has to restrict airflow somewhat vs nothing at all. Just my thoughts, but go try er out and let us know!

Not sensative at all!

My thinking is this:

The stock hole was for sure smaller than what I have now and I have actually added more volume to the plenum area now by removing the headlights and more flow with the pre-filter up front... In addition I have the SLP side vents and next to the speedo vent as well.

I am anxiuos to try it, You can definatly hear the difference in air flow from before at just an iddle.

65degrees maybe? 75 is 15degrees off 90... fwiw...

 

[dub]

Sorry you are correct! it is 75 & 15..

 

[Scoutin Wyo]

Any pictures of the underside of the hood?


As to the air restriction, the manufacture that sells a similar (& overpriced) product claims a GAIN in HP using the filter.

I will put up a pic tomorrow. I havent seen the other filter but I could just about guarentee that this filter and neck are larger than that one!

 

[hudini]

I think it's a rad idea and design...You will be filtering out everything, belt dust, the occasional pine needle, dust from storage, etc...

I don't think you can get enough air to these motors so opening up more volume is the only way to go!

Now if you would only make fule injection for my 910 haha j/k

Nice job

Thanks hudini!

Here is a pic from the under side of the hood.
