Installing a cone filter..

[Sankekur]

A interesting thermally isolating material is the tiles use on spacecraft that need to re-enter the earth's atmosphere, they are made of silica fibers (sodium silicide if I am not mistaken), you can heat it to above a 1000 degrees C so that it glows white-hot but it radiates so little heat that you can handle it with your bare hands.
This would be my material of choice for a heat shield, if I had the money

I thought the material can radiate heat so quickly that if you raise it to the 1000 degrees C you can touch it within a matter of seconds... :thinking:

I might be mistaken but as I understand it the heat conduction takes place rapidly between the tile surface and air the surrounding, but the heat conduction from the core to the surface is really slow so it can be handled a few seconds after being heated.
Also I have a foto of a guy holding a glowing white-hot piece of tile in his hand, but I'll have to scan it, I can do that if you want to see

+1 to a double walled sodium silicide heat shield with a vacuum core (also, this is the alternative definition of over-kill )

I was thinking... yip I know... dangerous!! :mmm:
So why not run a pipe from your left ac vent, the pasanger one, that in my car is never used,
so that the cold air from the ac gets blown into the air-intake, thus cool air coming in all the time... :dunno:
Won't that solve the cooling problem??

does the aircon not release a gas as well? This may have a reaction with the engine...

I remember reading a post from Gizmo I think where he ranted about this type of idea.

imp:
The gas is used inside the system to cool the air,
otherwhise we would all be gassed!!! :hammerhead:
Mind you, your own gas doesn't count!! :nono:

I've seen a photo like the one you're talking about - pretty cool. :thumb: Post it anyway.

That would at least explain how it's glowing while he was holding it. That is an incredible material. Has a low thermal diffusivity but high heat capacity. The material will be able to lose heat by convection, but conduction is really slow...

Some say overkill, others say best heat shield available... :mmm:

Interesting idea... :clap: considering a car's intake, I think it's got to do with air pressure and temperature. So need high pressure - like at the front of the car - and low temp... If you can get it flowing and keep it cool, all will be good. I might be wrong though. :dunno:

Old school pic of note! awesome...

it would be better to fit an intercooler than run the ac, but if you have an intercooler the engine response will not be as good and before you fitted it

In the end if you want some real proper value for money gains, either go for boost, gas or both

hey hey... this is a pic from my ex ride
nice to see it popping
expensive little cai's, these gruppe-m's

Or this you get a simota replica for less money than gruppeM:

Drop the CONE!! it's not toped up with ICE-CREAM!! actually LAWA from your engine compartment.

If only I could understand what you are trying to say...

I think what he is trying to say is that he stuffed an icecream cone into his air intake for some real cold air induction.


So, when you fitted the cone did you remember to at least remove the citi from the cone first

 

[moranor@axis]

cones are for icecream so done eat yellow snow:thinking:

it made sense in my head:dunno:

 

[bimmer330]

nnnnnnnnnnnarg dudes!!!:clap:
I'm talking about hot air and cold air here.

 

[moranor@axis]

did you sprinkle a little crack on your ice cream?

 

[andrewbuch]

nnnnnnnnnnnarg dudes!!!:clap:

So this statement is referring to hot air and cold air ???

Could've fooled me

I have a cone filter on my e30 and it sounds great but i noticed ive lost performance. When the motor is stil cold or driving in the early mornings the car is not that bad but as soon as the cars engine heat warms the filter or the pipe the car feels like I have the hand break on. So tomorrow im yanking that shit out and im going to put the original airbox with filter back
