Ya they all came that way. Just drill it out and then it will be functional.
ya trying to think of a way to get a "cold air intake" built on it.

I am thinking about just putting on another elbow and just come straight trough the hood with a air filter I also talked with Jim at Evo and he said that they were making a cold air intake that would look factory. So going to wait and see what they come out with.
havnt heard about the evo one. was thinking an alum Y off the stock plactic thing them carbon fiber tubes to boondocker filters where the stock intake comes up. and take out 95% of the plastic from under neith the hood
Intake options
Ditch a ton of plastic and the filter with the straight thru the hood option. Tight 90 off factory plastic elbow.

I have also used factory intake with the plug taken out and still ditch the factory filter. Couple different ways to go all with varying degrees of work.

This is what i came up with on mine so far. Im not going to use the k&n filter was just using it for mock up cause I had it laying around. I will be using the BD filter like Justboostit used on his. I just have to find out how he got it cause its not on their website. I put mine a little farther back than Justboostit did because I wanted it out of the way of the head light.
Justboostit....if you can tell me how to get my hands on the BD filter you have that would be great. Thanks!

FWIW, there is no power gained on the dyno from opening that hole, or removing the air filter...
What ever you do, do not run that sled without some sort of air filtration, you will destroy the turbo. Believe it or not snow dust will erode the compressor wheel....

Thanks for the heads up, but there alot of people doing this to their sleds. Not saying your wrong but if justboostit did a couple different intakes on his or others and if it was gona be bad I dont think he would have done it. That is why I chose to do one similar to his.
Anyways i just got my BD filter today and finished my intake tonight so here is the finished pictures.

We'll have the 2 prototypes at Haydays - one on our sled, one for display. The intake produces 5 hp more than stock above 7900 rpms on the Big Chute/Super Chute.
Intakes with prefilters
Never seen turbo issues with prefilter socks in 5 years with mine, or on anyone else's in the turbo mountain segment. That's all I've ever seen on front or rear mount turbos on Yammies.
Sorry f7, somehow missed this post. Yes that kit is not on their site, glad you managed to get a hold of it.

Awesome. The bottom line is the stock intake mounted to the hood is heavy.
just got my 11t and the hood is so heavy anyone cutting some of the black plastic out
You are correct. The main restriction is the factory 90 that hooks to the turbo. Put a K&N directly on the turbo and people are seeing major gains on the track dyno. Put a K&N on the top of the factory 90 and it is no better than running through the factory system.
Flatlanders can run the filter down low with the sock on it. For mountain riding you probably need to get it up out of the snow through the hood.

We have seen on our big turbo setups that the factory air filter becomes a restriction at higher rpms and power levels. All of our big turbo setups use a 60mm intake boot which moves the restriction back to the filter.

I don't have the stock 90 and if you guys look I do have a mountain sled in the picture so I'm not a "flat lander" so yes that hole I cut in my sled will help with more hp. My sled is not stock so it needs that added air flow. Trust me I wasn't cutting a hole in my hood for looks it was intended for weight savings and performance.
P.S thanks Evo for all your hard work!
