Cold Air Intake Temperature Reading

[chaleurphantom]

Re-designed my WAI to a CAI...lol

Also added an air chute, directed at clutches...

Will see how temps are riding Saturday.

I have the Kolenko CAI. It fits right up to the stock, front inlet screen. Also the filter cone that it comes with has an inlet right in front of it.

My clutch's are very cool now, luke warm at best. The thing is I made a lot of changes at once. I installed a clutching set up from Ron Ward so that may be a factor.

I also removed the stock plenum that was going to the stock air intake. My theory is that warm air rises and vent out the factory frogskins on either side of dash board.

Sound like what I did last season.

What is a Kolenko CAI, I feel im pretty up to date on most things here but never heard or seen this name.

No Pics?

Im of the mind these days, to test what I come up with before posting it all. In August when I do stuff, i cant really test, but now we are riding so I like to at least give it a full weekend or so to see if it does much.

It certainly makes sense to grab CAI air from screen and not from an entire k&n sucking all around circumference, of which much of it is very hot temps. Even though my original CAI was slammed into the nose, and angled nicely I think this new design will certainly be cooler IAT's.

It made sense to have a chute below the CIA aimed at clutches, just made out of something I had here. Surely could make something much nicer im sure.lol

Kolenko CAI is from a guy on ebay. (and FB) It's the one I would get if I wasn't waiting for the external from Tommcat. Seems to fit the closest to the front from the ones I have looked at.

Ok, probably not good then...Ive seen all the ebay kits and anything using a k&n will not suck cold air.

Is this it below? My original design does better then this one.

Ya, not as good as the one I ran either, and mine still sucks 100F air right at the filter inlet.

Engine consumes way more air than comes thru that intake.

 

[ROCKERDAN]

Mine was much closer to the screen, and my k&n was angled perfectly so the entire side of it could suck from the screen. It held temps down very good IMO. But there was still the fact the air is sucking from the ENTIRE circumference of the k&N. So while it sucking cold air on front side in my design, its also sucking same amt of air from backside which is not cold air. In addition, the air sucking from bottom of k&n is robbing the COLD air that should be going to clutches.

We are an OCD bunch here, I thought it was only me but this Winder has brought out the OCD in all of us immensely! I knew I could re-design the CAI to suck cold air 99% rather then 30% through a k&n. And then I felt like I may as well aim a chute, to direct air to the clutches. Its a win win IMO, and keep the stock massive air box out of the way which I like, and is a larger intake(square inch) then the tiny stock plastic shroud that I have removed.

Below is a pic if my original CAI that I just removed, Have not seen any with the angle and k&n this tight against screen. But in the end, it still will suck some warm air, even though its darn good.

New design will be 99% cold air only.

RockerDan, yes this is the one. What it doesnt show is the front of the filter is also open filter material and mine sits up right next to screen. So it also pulls air in from screen area and is not blocked off like most of the filters I have seen including yours.

Ok, so maybe you haven't been following along? While a k&n with ability to suck from the front is good, it still will suck from INSIDE the cowl, so its getting plenty of underhood heat as TESTED by Mike.

My filter if you look closely, is a CONE shape, which I chose specifically and angled it tight against screen...so mine will actually pull more cold air then yours. Very simple to see.

That being said, I have removed my design to go after 99% cold air and little to NO warm air.

Not trying to argue here. Totally agree it will pull in some warm air. Like I said to Mr Knapp, I will be riding today and will monitor my temps. Just want to see what people are running for temps with stock air box vs these WAI! LOL. Also, thanks for all you do on this forum. Your insights and build are incredible!

Yeah, I am not sure how much warm air is up front when sled is at speed? I am thinking air will flow front to rear when underway. Like I said, my air intake temp when trail riding is 45f to 55f ballpark. I am not sure where this temperature reading is collected. Of course, air temperature will increase after compression. Is it before or after compressor? About midway on bar graph.

I am also heading out today. I will monitor again.

The important thing to look for is how much over ambient temps is the intake temp running on an average.

Check it with a WAI, then check it with the Stock airbox. I've seen the stock airbox at 10F over ambient. WAI system is 20-30 over ambient, and the harder you are push it, the higher the temps go yet with WAI. Also the higher the ambient temp goes, it compounds even higher with the WAI system over the stock airbox.

It gets to a point that on a warm day say 30-35F on a WAI system, the intake temps generally run up there at 60-70F just cruising, and if you get into the throttle even the slightest you will be at 80-90F on the big tunes, this is where the stock airbox will help the most dropping intake temps. You will se it 20-30F cooler on warmer days vs the WAI.

What I have seen is power falls of drastically up over 90-100F. Test it for yourself. You will see the CAI is not actually CAI.

Like I've said before, the WAI will need a bit more clutch weight and it makes more boost, but it also makes more heat, and draws hotter underhood air as well as robbing air that could be going to the clutches and keeping the belt on it. IMO you can click up one tune and get better power than the WAI provides. So honestly, what good is the CAI until you are maxed out on tunes? And at that point, you are going to me more concerned with octane and deto than the extra 5HP and .5lbs of boost is going to do for you and the belt you are about to blow anyway.

That explanation sounds very reasonable.

I would not think twice about removing CAI if I see temps around 75f.

Thanks
