I have D&D 255 flash on my sled. Had them Dyno it same day and Dale told me before we did, CAI will add 5hp. Guess what? Made 260hp! Dale knows his s..t!

Yes, but it comes with a .5 lb boost increase also. So in reality there is no gain from the part itself, just the boost increase. You know why the speed and drag sleds all run the ram air intake out the front of the hood? It builds boost to the already too small turbo and makes more power. When your limited to the puny stock turbo you do what you can to make a few more HP.

If you want more power for the trail, its cheaper and easier to go to next size up tune and reap the benefit of colder air to the clutches and cooler belt and clutches IMO. Just throwing that fact out there. Intake and clutches will stay cooler-longer with the stock airbox.

May I ask what your average intake temps are now with stock box. Highest mine got breaking trail 52 degrees lowest on groomed trails 39.

On average it’s 10-15F cooler than running the CAI. I meant WAI.


Belt and clutches are also the same cooler. Same day same conditions testing.

If you want or need the added power just click up one tune and it more than makes up for it.

Can't say about cooler clutches. I know you have a lot on your plate but if you can try and monitor your intake temps and report back on them. I think for the cooler clutches, I am going to add the holes to the belly pan like they did on my 2012 F8 and see how that works out. I have BOP belly pan protector but will drill holes in that and hopefully not weaken it too much!

I've gone back and forth till I was blue in the face with the WAI. Its not about the temps being run, its how much cooler the stock intake runs over the WAI. In one blast with the WAI, temps get into the 120'sF on the 290 tune. With the stock box they will get up there at 90-100F. If the turbo is spooling hard, its making heat and hot intake temps.

Installing the stock airbox is like adding a larger intercooler. Larger intercooler up front drops temps about 10F also as an example.

Running around at average trail speeds, the stock box is 10-15F cooler over a good WAI stuffed right up into the intake screen where its robbing air that could be going to cool the clutches. Bottom line, stock airbox runs cooler intake temps and will stave off the heat longer.

When these machines get up at 90-100F intake temps, the power goes away quickly. Want a real aftermarket CAI, it has to go outside the hood, and if it goes outside the hood you better be sure you can fuel it for that. I went real lean with it when I did that. 12.8-12.9 and even 13.0 AF ratio. Needless to say I couldn't leave it that lean so had to go away from the filter outside the hood like I had it.

When I get the opportunity to wring this thing out on a lake, I will keep you posted on my temps and if they go off the charts like you say. If so, stock box will be going back on! Lol. Also, thanks for all your replies and comments. Can't wait to see how your clutching works out cause mine is really rattling now too. Should have called sled RATTLESNAKE!

My design is different....Mine uses my RAM AIR theory(which i made back in APX days) and is used as Mike mentions at the radar track on most all sleds there.

I think this design will work well at CAI temps from what I see.....But for me, k&n is gone.

I wanted the cold air for intake, and also cold air for clutches.....so I made both things at same time with all in mind.

I have never felt the stock intake was 'enough' flow....it may be cool, but my new design will be colder and rammed, while INCREASING direct cold air to clutches.

My biggest concern now will be AFR...

Time to pony up for a standalone so you can tune the AFR's where you want them....lol

RockerDan, tried to post pics of intake but keeps coming up as to large.

It's all good. The cool factor of the filter negates the uncool bus-like windshield.
In addition, if I was travelling north to ride and it was -35 celcius like last week, I'd have one too.(temporarily)

Being mine is a DX it came with one. It's colder than Fu here right now. That just makes me want to just leave the grandpa shield on!

Dan this design your talking about in this thread, is it different from the system in your build post???
