So I was reading this thread on the E55 board
https://mbworld.org/forums/w211-amg/...-pictures.html

And it got me thinking... Our(C55) air box sits right on top of the engine block. I can feel there is noticeable power loss due to heat soak when I get out and drive harder for an extended period of time or whenever it gets in the 90s and 100s.

Has anyone taken off their air box and wrapped/lined the bottom with some sort of insulation(or whatever you call it) to keep the heat from going straight into the bottom of the air box?

(ps our search sucks so sorry if this has been answed before)

not yet. i will be doing it soon (next month or so). i'm gonna wrap the intake pipes and the air boxes. i just wanted to wait to get my data logger so i can determine the difference the heat wrapping did on the IATs

SoCalC55

That would be nice! I just think there has to be some product at say Home Depot that you can buy for cheap that will work really well. Nothing really fancy, but even a small barrier between the bottom of the intake box and the engine has to produce sizeable results.

I did mine long time ago and just recently wrapped mine air box tubes with one of those insulation. You probably see my pics from that thread thou.

heres the best of both worlds jturkel!!
try any motorcycle shop. should have the wrap you need or dei has it

yah i would, but i dont want to spend $550 on an intake. I assembled mine for $270 and am quite happy with it. I will just do the DEI wrap stuff.

There have been a couple threads about that with lots of info and links and pictures in both the E55 W211 AMG forum and the CLS55 AMG forum

FrankW

did it on my 32 box and works

DEI sells the heat insulation cloth or you can search for Thermo-tec which is what i used back then.

my friend also did his M112 airbox which underlines the entire box. he used velcro and because the thermo cloth works very well the velcro doesn't come off at all.

How do you install this ? from where to where ? lol

I just drive faster-I find it lowers my IAT by 2-3 deg when I break 100
I still say its not about insulating-but getting the heat out (CF hood, hood vents, ect)-I can see more of a beni from that....

FrankW

having both works too.

Found it this is what I got under the air box,

I used this for my intake tubes,

While I haven't insulated the actual airbox I'm currently using the CLK350 airtubes which are a different material than the stock ones and larger also:

jturkel

so he attached the thermocloth to the airboxes with velcro strips? and they were able to remain fasted on there with the heat?

haha......Frank and I are all for a CF vented hood. he suggested it in a thread in the W203 section and i posted a pic and supported it, and then some newb tried to flame me by calling it rice.

all that would help though for sure. and i've removed all my weather stripping / rubber engine bay lining to maximize air flow in and out.

jturkel

anyone think this is overkill?

another really good thread with lots of links/pics: https://mbworld.org/forums/w211-amg/...t-results.html

I went when he decide to velcro it, but it has never failed on him. the thermo-tec cloth works incredibly. the cloth can withstand 2000deg F.

this is what we used http://www.thermotec.com/aluminized-heat-barrier.html

jturkel

haha, i would have too. thats why i asked.

hmm, how do you think that thermotec stuff in that link would compare to the stuff posted in this thread already here: http://www.summitracing.com/parts/TH...5/?image=large

huge price difference, but it looks like both are aluminized with weaved silica.

FrankW

they are the same cloth. one's just with the adhesive back which makes it easier for you to intall. we bought the non-adhesive one because for the same money it gives you heck of a lot more cloth to work with. attaching them isn't that hard either.

oh... on the cloth end my buddy sewed the velcro to the cloth btw.

jturkel

oops. didnt notice the size difference. that would have been a good thing to check. no wonder why it seemed to be such a killer deal haha....thanks for the info frank

SoCalC55

Have any of the cloth left over Frank

haha

JonMBZ

could you route some of the A/Cs cold air into the intake to moderate the heat levels? Put a bigger A/C Compressor lol

Quicktwinturbo

I thought about doing that....How's the fitment?
please do dyno when you get a chance

FrankW

used it all up. i did the intake tube and my buddy did his airbox.

BenzoAMGpower

The only way a vented hood is going to work is if you cut the insulation under the hood or remove it completely!!

It's all about give and take... though this would work on getting the heat out, one would wonder if the direct heat on the underside of the hood from removing the entire underhood insulation will do anything to the paint on top of the hood.

wawy

It's an exact fit on both ends. The only thing is it's a tad short and I had to use some hose clamps. I did multiple dynos with these and the Renntech airbox and K&Ns. Under those controlled conditions and with their shop fan blowing air I got around 6 or 7 rwhp/tq consistently. I don't think any of that had anything to do with the airtubes but you never know. I will say that they don't seem to get as hot to the touch as the stock plastic ones though. Possibly in real world driving conditions the CLK tubes may provide more of a benefit/gain than in a shop on a dyno

FrankW

should be alright. a lot of cars are running without hood insulation.
