aero charger deep powder or cold air snorkel

fredw · Dec 25, 2011

and the night before christmas bored as hell, went to the garage with a bottle of crown royal and did some fabrication, and other than a few minor issues a snorkel was fitted...and in the morning a headace from hell and a comment of what the hell did i do to the sled...lol

i have been seeing a lot of crap in the turbo housing and compressor fins, from belt dust to dirt oil film to insulation from the pipe, plus all the higher temps and charge temps assoiciated with under hood temps

tell me what you think, my duramax intake is not that big... looks somewhat wild, and from the backyard testing, it spools even quicer than before, and still leg room for tight tree riding...

4 inch silicone 45 degree hose and 4 inch filter housing with frogskin rap

brad its being pattened as we speak...lol are you can buy my pattent with a free turbo kit :canada:

hope to try out this week, now hope we can start to see some big dumps

Octanee · Dec 25, 2011

curious, where did you get that snorkel? best i could find was buying a boondockers 1 that is 3" which is pretty big anyhow so no issue there,

also looks good! i know with my turbo project i went the outside snorkel for lower charge temps, sucking in fresh air, also the air is going to be a more consistent temp, and i figure that it would be hard to tune with underhood air as it can get hot and cold real fast depending what snow your in, also i am not running a intercooler or av gas, just 94 octane fuel, so the cooler air i can get for cooler charge temps the better

also as they say, or im told the snorkel will add more power overall then just underhood air....

but yeah, lookin good!, i think it gives the sled some "attitude"

You'll definitely be getting some cold air w/ that. It wouldn't work for my riding style. I've got venting right there on my turbo, and I've bent it when mashing my knee into it. I'd have to wear knee guards to ride yours.

Not the prettiest, but it should work good.
I have ben trying to decide what the best way is or how to do a cold air intake. I just don't like the way the big filter sticking up out of the body work looks.
I just have a screen over my intake. as you said it still gets a bit of stuff in their. Mine also gets some powder in and bogs once in awhile on the real deep days sidehilling to the right. I am going to build a screen/box over the intake to my turbo and put prefilter material over it. Filter the air better and keep it from boging from getting snow in. I have alot of vents and will be putting the 2012 belt gaurd on. Hopeing it will move some underhood air and keep the underhood temps down a little more. Not quite as good as a snorkel, but hopeing it isn't too much worse. I do hvac for a living so I have some nice thermometers with remote sensors, etc. I will have to bring one with me one day and put a prob on the air intake to see what the temps are like.

Absolutely!

A cold air intake is an absolute must! My sled (also an Aero) runs like dogs#$t with no cold air intake. As long as you can still manuever with it where its at, you're going have a "NEW" sled. Your charge temps will drop 20 degrees @ 2500 ft. when its 5*F.

also interested in the filter cage,where did u get it an how much ?

fredw · Dec 26, 2011

i hope it works like it should, i had some filter screen from a used cab air filter off the combine, got the idea from that and had some alone time with the welder, i might be able to build a few more after the new year

i have had good performance with the stock setup, so i cant wait to see what it will do with this, plan to be drawing 360c/f soon at 7000 feet, so a 20degree drop in charge temps should be a noticable gain

You should have ran it straight up the top. You could have notched the panel, that way panel still opens like stock, won't hit your knee, and wouldn't stick out so far either. Great idea. Just need a bit better placement. If I were to do cold air on a doo, plum a 3" mandrel bend into the stock air box, and add an RS intake/ slp intake. Lots of volume and no " my sled looks like it has a you know what sticking out". Or ran it out the console cowling. Then the panel becomes a non issue.

Know a guy who ran a tube into the air box on a pro, what a great setup. All of the good, none of the bad.

Just getting more air to the turbo does wonders. Sled goes from just ok to pornstar with a good intake. Witnessed it first hand on an apex.

I'll bet liquid/air and an intake is just going to rock.

fredw · Dec 27, 2011

i thought of running it strait up the top, but there is not enough room between side pannel and turbo, hose would ob been squashed quit bad, also though about running it higher above cluster, but could not make it work, stock airbox is removed, but a good idea

how big of a pain is it to get in your side pannel?

thats what i was thinking

fredw · Dec 27, 2011

actually quite easy, remove a 4 inch clamp and slid the hose inside the cover, less than thirty seconds and your in

fredw · Dec 27, 2011

so what boost is the maximuim i could run with out detonation and no intercooler on 91 fuel?? is their a det sensor on the etec, and can i guy rely on that??

I unload as low as 4,500'. I do not hold it pined for more then a few seconds at this elevation though. Actual riding or any time I hold it pined for more then a few seconds is around 6000' and up. I ran 7lbs on non ethanol premium pump for the first year. i turned it up a few times to 10-12lbs with more race gas in it. Once every 10 rides or so it would set the stock knock sensor off and not run so good. my buddies NA xp with slp pipe and head would run about the same on the same days. so I started runing a gallon of 107mon fuel per tank and didn't have any more problems. last year I ran 10.3lbs of boost most of the year. ran premium non ethanol pump and 27% 107 mon. I have 5.5gallon gas cans. I put 1.5 gallons of 107mon in a can and fill the rest with premium pump. Then fill the sled with the cans to make sure I have the exact same ratio every time. Ran great all of last year. I am runing stock compresion and a garrett 2871 with tial .84 exhaust houseing and tial external wastegate.
Just letting you know what worked for me. I plan on runing 11.4lbs spring in the wastegate this year. Still doing some work to my sled and waiting for the good snow to hopefully get here soon.

fredw · Dec 28, 2011

now are you talking a etec here and is this a aero charger... because running 7lbs and 91 octane would be sweet at 7000 feet, i had thought the aero kit needed some race in at that boost

Did you miss this part Fredw?

badass1000 · Dec 28, 2011

as posted above.

I am runing stock compresion and a garrett 2871 with tial .84 exhaust houseing and tial external wastegate.

It is a 800r carb.

My sled has never had any signs of detonation. Just it would not run as good and the knock sensor would go off on the days the gas station got bad gas or something. I would run a gallon of 105-107mon fuel per tank just to play it safe.
Only engine damage I have ever had on my 08 xp is the mag side crank seal went out at the end of the season two years ago. seized that piston. If it makes it through this year I am going to rebuild the crank next year. I put new pistons in it every year since I put the turbo on.

fredw · Dec 29, 2011

yes i did miss that, thanks

ya, pistons one a year is cheap insurance that is for sure. i heard some guys running 7psi on pump gas, but no wot till 6000 feet or higher

so withs tock compression the 800r with the 2871 should be making some real sweet hp, whats your clutch pin weight and ramps, thanks

badass1000 · Dec 29, 2011

I posted in the turbo clutching post what all I have in for clutching.

20.8 gram pins, 9.9 gram rollers, stock arms, dj mountain ramps, 160/350 primary spring, 20/45 gearing, 155x2.5 CE track, dj qr11 helix. that is at 10.3lbs of boost. I think i was a gram lighter at 7lbs of boost. can't remember.

joe called me today and I talked to him for awhile. going to gear it down some more to get closer to 1:1 on the clutches. going to do 20/49 for sure. maybee as much as 20/51. he is sending out his nc-d2 helix and 200/350 primary spring.

fredw · Dec 30, 2011

9 9 gram rollers....?? what is the weight of stock rollers, are yours oversisezed

we also have joey stuff in the trash kit, if we ever can get it to run right, we can test his stuff, the trash kit has the boost it box on now, but we are still having issues, it seams to causing a engine code, yesterday it pulled a rave valve not closing on idle code... this sled has spent time at more than a few shops, and no seams to figure it out, we have the other trash kit for sale, it never been out of the box...5 grand takes it
