Cold Air Intake

Has anyone made thier own? I saw the one on twisted turbos web site but I think that is only for cats (not sure)? Maybe Shain can chime in. I have been running some ideas over but have not attempted to build anything yet? Is it worth it to try to build or is a shocktower vent going to do the same job? As many turbo dragons as there are I am sure I am not the first to ponder this but my searchs have come up pretty empty. Any input would be great- Thanks: Aaron
 
I have my own cold air setup on my Boondocker turbo setup. I came straight out of the turbo, made a 90, and then straight out of my hood. Pretty straight forward setup. The only pictures I have of it are the ones below - I will try to get a picture of it under the hood.

Where did you get those shock guards?
 
Have been thinking about making my own cold air intake for my silber setup, but havent decided which way im gonna go. Straight through the hood or try to utilize the stock option.

have you had any problems wth your setup snopro911, thinking snow buildup or something?

I actually think it is weird that not more of the companys providing turbos, thinking silber and boondocker has made a cold air option.

Drawing cold fresh air has got to be an alot better option than the air under the hood, the colder the better....thinking this would be something to sort out before adding an intercooler?(a combination of this would be the best)

I didn't use this setup last year - I tried Boondocker's intercooler. But I am going back to this setup for this year. When I rode with this setup previously it worked well with no snow buildup - I was surprised how well it worked.

I have talked to Boondockers several times about a cold air intake - they don't seem interested in pursuing one, which I'm not sure why?

If you haven't checked out lightening800's turbo in the classified section you should. It looks like an amazing sled, and it has one of the best cold air intakes I have seen. It is on a twisted turbo setup - check it out:

That looks like a very good setup, short ways from the turbo to the filter and low exposure to snow. But thinking using this kind of intake would prove to be dificult with the turbo being in an totally different place on the silber/boondocker setup?

I have been thinking about making a funnel(not sure if this is the correct word) from the turbo which seals around the area and draws air from my shock tower vent. But i was sceptical because the possibility of snow buildup in deep conditions.

Have you removed the interooler for this year, and if so why?
Suppose to upgrade to an intercooler now, so any opinions is appreciated:)

btw, can you post some underhood pics of that intake...have an thrasher hood and im going to try it.
and do you have to remove the filter when opening the hood?

snopro911- That is pretty much exactly what I have been thinking about doing. I mean exactly!!!!I have a couple questions....

1. Could you please post pictures of under the hood and with side panel off? I didnt know if there would be enough room between exhaust pipe and the shock tower but seems you made it work.

2. How much time do you have with this setup? I was worried the tube from the turbo to the intake filter would get to hot at the thinnest point?

3 Have you noticed what your charge tube temps were before and after? Wondering what kind of temp change to expect.

4. Someone else asked this but can you open your hood without removing your intake?

5. what is the intake tube made of? High temp rubber or a plastic?

Thanks again brother- Cant wait to see the pics
 
have ran the same set up on mine for the past three years in the spring time.
i'd say i have roughly 2000 miles on my sled with the intake through the hood, works really well when the ambient air temps are above 40 degrees, other than that though i really didnt find it needed.

you can definitely here the turbo a lot more with the intake snorkeled through the hood like that though!

2000ish miles, no issues with the tube getting hot

3 Have you noticed what your charge tube temps were before and after? Wondering what kind of temp change to expect.
charge temps were down by 40-50 degrees on warm days (above 40 degrees F) didnt find it to make very big of a difference on cold winter days so i only run it in the spring time

4. Someone else asked this but can you open your hood without removing your intake?
yes you can open your hood with out removing your intake, you just have to cut the hole a little larger than the intake, the elbow off the turbo is fairly flexible so you just move it around a little as you open your hood.

5. what is the intake tube made of? High temp rubber or a plastic?
yes it is made of high temp rubber, you can find it at any local truck shop, going to run you about $50 for the elbow, straight hose piece and clamps
 
Thanks for posting the pictures. I will start mine this week.
Also snopro911 did you notice an increase in performence with the pipe heat wrapped? I assume that is a stock pipe heat wrapped but correct me if i am wrong.
 
I did it more for heat protection than anything. My heat shield on my stock pipe was coming apart so I took it off completely and wrapped it with header wrap. Haven't had any issues with heat since the pipe has been wrapped.

Good luck with your build - get us some pictures when you have it completed.

Thanks -
 
finished product

This weekend it was almost 50 degrees on the pass. I really noticed my charge tube temps were pretty high. The highest I saw was 206. Thats no good. So I came home and decided I would go ahead with the cold air intake build as the temps stay warm with the onset of spring. I went down to the local O'Riely Auto parts and got everything I needed.

I decided to go with Spectre polihed aluminum (SUCKER FOR BLING) 4" intake tubing. They offer a 3" plastic version but I figured it would melt being close to pipe but I could be wrong.

Parts List

1 90 degree 4" elbow
2 strait intake pipes 6" long each
1 cone air filter
1 reducer- 4" to 3" (comes with 2 clamps)
2 couplers (each come with 2 clamps)
TOTAL COST $115Although only one strait pipe is shown I used 2, same for couplers

Here is the mounted intake

And with the hood closed

To answer some obvious questions....
* Yes, you do have to remove the air filter on the top to open the hood. It is only 1 clamp so no big deal.
* There is a prefilter available from K&N or Injen Technologies. Both were under $30. I am ordering the K&N.
* I cut the hood with a hole saw to begin with and finshed up with a skill saw to make everything come out nice and clean.

I have not ran this on the snow but anything has to be an improvement over the under hood heat. I am expecting t least 40-50 degrees (Jeremy mentioned this range in above post) drop in charge tube temp. Should work great in the spring warm!!!!!!! Will let everyone know how it goes tomorrow after first on snow testing. Project took just over two hours to complete
 
What happens to this snorkel if you roll the sled?

Well that remains to be seen. It is much more rigid than you think. I'm not saying that it will take a rollover because I dont know but it is really rigid. The hole I cut in the hood does not allow it to move at all towards front of sled and has about 1/4 inch it can move towards the rider. I would imagine that in the powder the snorkel will take the roll with no problem. This may not be the case in the set up hardpack of spring.

Luckily I am much more to prone to rolling my sled in powder (usuallt to get unstuck) and feel if I am rolling my sled in hard pack I have....
A lost control and am no longer on the sled
B Went somewhere I def should not have gone
C Wrecked and now have much bigger issues to deal with than a $115 air intake or of course
D ALL OF THE ABOVE (the worst)


That is a concern of mine though and thanks for mentioning it. Hope I dont have to come on here and give you guys a first hand account of the carnage.

Your post made me laugh. Last year was an A, B, C and D year for me. I like the idea of the cold air intake and would like to run one on this years turbo. I worry about the rollovers thought. I tend to have more than my fair share of them.
But ya, keep us posted on how it holds up.
 
COLD AIR INTAKE

The HM Turbos Kits come standard with a cold air intake. I feel like it is a must on any turbo. Check out the web site.
