To Hot?

[Mike~p]

well today i was showing a friend my boost gauge install after a 10-15 min drive and it was night and i noticed the turbo area was glowing red...and i mean like crazy red...ive never really seen it like that before and when i was putting my hand near my intake it was 100% hot air....well i kno no1 here cept a few us like the evoms air induction kit but i do own it and i was wondering 2 things....first off- is it normal for it to be that red...and second i need ideas for heat shielding to get rid of some of the heat going to my intake......i kno some y'all have done it so any imput/pics would be great....thanks

What are you boosting at? I've heard that the KO3 glows after hard runs. The OEM airbox is the best you can do. Maybe add some more heatshielding around the turbo? But then again your turbo would heat up like crazy and get heatsoaked.

well im runnin the k04 if that means anythin...but the evoms came with a small heat sheild...but i doubt it does anything


but what kind of stuff would i need to make better shielding

[dukez]

Turbo glow is normal for any turbo. Yes it does get hot in there. Thats why poeple always say (or should of told you) an intake would rob HP (sucking hot air) instead of any beneficial gain.

If you want to keep it, get a bunch of aluminum foil and wrap that sucker up :)

Perfectly normal with the very restrictive stock manifold

I have an Evo MS intake, but i added alot of heatshield and DYI air box to cover things up in there. It stays cool if u hop out and open the hood right away after u stop, but when u sit for a bit and open the hood and check, it is still warm due to the fact that warm air is blow in the engine area by the fan. YOu have a pix of your intake? I want to see how yours is looking

[Mike~p]

yeah i can take one when i get home from work today...what kind or stuff did you use to sheild it? and do you have pics

[skene]

did you use the stock airbox metal heatshield?

You are supposed to attach that to the EVO heatshield.

It's a turbo though... using exhaust gases to spin the turbine... of course it's going to glow when it's hot... all metal glows when it hits certain temperatures.

If I were you I'd ditch that intake kit. I don't care how much heat shielding you use, you will always be drawing the warm air from under the hood. Like JMG mentioned, the stock setup is ideal.

Now if you're running a much larger turbo (more than a K04) then I'd guess a cone is justified, routed away from the heat.

[Mike~p]

theres gotta be someway to get it to work better.....heat shield tapes...a thicker shield....ram air directly to the cone




i dont wanna sound flame but i love the sound of my intake and i love turning heads when drivin by....or havin all the ricer kids jaws drop an stuff like that

[skene]

ummmmm... poor excuse.... cause when is it sucking in air from the engine?

at idle...... ooooooooo big performance losses there.

When you are moving the intake isnt taking in any hot air.

[sighpost]

I used dryer vent duct to direct the cool air from the ground (lower front bumper pass side) up the filter than I covered the filter with a big aluminum box.
Here is the DIY link

And for those of you wondering, yes there is a shield going in between the turbo and the filter. It goes all the way to the frame mount.

BLAH

[sighpost]

BLAH?

[Mike~p]

i was juss searching old threds for more on heat shielding an y'all have seen this but im newer so i didnt

^i could definitly do something like that or what sighpost had done above and then also do what kurzer had posted a while back

http://audi12v.home.comcast.net/caivs.html


i dunno...i like it for sum reason and i wanna do sumthin to make it just as good as stock or if possible a little better

[Mike~p]

haha nah that wasnt to your post....it was to skene's

[sighpost]

That second link has a cool little bumper vent for the ram air intake. I think I am gonna add taht to my project. I also think Im gonna wrap the air hose going to the turbo in insulation.

[Mike~p]

skene- theres a good chance im wrong but when u give it gas then let off isnt it the air echo'n through the piping.......thats what it sounds like to me

turbos dont get heat soaked, intercoolers do. any turbo after beating the shit out of it will glow red that is just what happens when hot air exiting a hot engine causes friction with the walls of the exhaust housing. pm jeff (that is his handle on here) he drives a B6 but managed to make him self a sick heatshield maybe he can show you some pics or point you in the right direction about making one like his.

oh and iirc he is running the GIAC chip which boost at 1.3-1.5 bar.

look at my sig. that glow is realy with a few effects

YES, alot of ppl forget to put that metal stock heatshield back on the Evo one

[Mike~p]

well i did some heatshielding and ill take pics today an post em

[littlewhite]

Sure, that will be great. I need to do somemore shielding and probably have a duct coming up from S4 bumper when i put the new bumper on

screw that i wish i still had my stock air box on mine... i wonder if a stock S4 airbox would work with a little customizing?

Does that mean you agree with me? I'm confused. I was saying that the stock air box is best (just to clarify).

I think the S4 air box is similar if not the same as the A4. Same concept at least. I think the S4 may share the same airbox found in the 2.8.


I so tired of these air intake threads. On a 1.8T, it's all a big waste of time, money, and possibly performance if you take out the stock box.

But, on a 2.8 I would venture to say there may be an advantage to running an open air element.

yes i agree with you about the stock airbox i have one of those "larger turbo setups" you said that might justify having an intake and i still dont want the damn thing on there like i have right now. about the 2.8 the MAF housing/intake hose on an S4 is 3" which is not the case on the 2.8.

i agree completely with you on the intake thing, i could see the 2.8 as there might now be as much heat in that area i am just not so sure about the airflow to it . imho intake would only work well if the person had their headlight removed

[Numbersix]

Unless you can get the intake a decent distance away from the hot side of the turbo and manifold, I don't understand why anyone would do an open element filter.

It's just begging for heatsoak, especially in aggressive stop and go driving. If you just do freeway driving or high-speed canyon runs, especially when the ambient temps are below 70 deg F? Great.

Otherwise, the stock 'box is very well designed to shield from heat, and protects the MAF from getting damaged by the oil that is on most cotton or foam filters.
