air intake

[Andrew C280]

ok some one explain to me why mercedes has run the air intake right over the hot engine, cold air is better for the engine right ?

so is it possible to relocate the air intake to the other side of the engine using some sort of mercedes parts ie from a
V8 or something ?

[jnolte]

possible??? anything is possible...


but you can run tubing down to the foglights for a ram air effect, speedybenz has done this in his C43, also 2phast did this in his C36:

i like his idea but i think it would be even better with the intake on the other side not crossing over the engine and thus not heating the air as much. how would i go about crafting a new air intake system are there kits or do i have to work on my own.

The only "cold air intake" ive ever seen is made by some rice company for the C280/36 if Im not mistaken.. the funny part is, its not even a cold air intake.. just replaces the airbox with a cone filter (but still located inside the engine bay... heat!!)

The only way to go is pure custom.. either fabricate something yourself with some 3" aluminum intake tubing or have a shop make one for you.
Maybe you could modify one half of an SL55 intake to be used on your C280, and run ducting to the fornt of the car to get cooler air.

Im making a cold air intake for my C230 Kompressor.. bought the K&N cone filter and an AEM bypass valve.. just need some 3" aluminum tubing now.
will post pics as I fabricate and of course of the final product.

where can I buy this aluminum tubeing what about platic fiberglass or carbon fiber ?

[ricerokets4life]

im not sure about aluminum. any exhaust shop should be able to fabricate a stainless steel pipe though.

[Andrew C280]

nice now you have me thinking

[SLAMMED_C]

Any large performance shop should sell lenghts of Aluminum intake tubing.

I wouldnt go with plastic as it would look tacky under the hood.. but if it gets the job done....
and as for carbon fiber.. I only know of BMW's that has intake kits made of carbon fiber.. maybe find soemone to make intake tubing out of carbon fiber..
and I dont recommend using stainless steel exhaust tubing for an intake.. aluminum weighs consideranly less.. and looks much nicer. although it does need to be specialy welded.

my friend has a carbon fiber intake on his golf too, but i doubt it would work for your car

slammed C where can i get some aluminum in toronto i dont think i can find any in kitchener

How do compensate for the 2 holes that the intake attaches too into the valve cover that I assume recirculates the air like an PCV valve?

[Andrew C280]

what are you talking about
???

[SLAMMED_C]

I had been talking to Performance impovements in scarborough, but they want $45 per 18" section of 3" intake pipe... I was hoping to find somewhere a bit cheaper than that.. so Im holding out till I do find someone else.

Do you mean the diverter valve thats on the side of my airbox??

let me see with my friend

he has a shop and can get metal at cost

I dont have a compressor so i dont thing i have that thing that your talking about

hey mr space dose your friend want to fab up something and send it to me

[MrSpace]

he can fab almost anything, he has all the machine shop equipment.

isnt steel cheaper than aluminum? and isnt it more resistant to heat?

[alhacker]

u could use any material u want as long as it doesn't generate heat steel does affect performance, all the people i know are using plastic tubing covered by the heat resistant material... it doesn't look good but its better performance wise... the best place for the air filter in the bumper u doent have to remove the foglight u could put it next to brakes air duct (is from the other side not the side of the foglight...)

[Andrew C280]

mr.space how much are we talking to fab up something ????

R, I'm not sure if it's the same on the I4's but on the I6's, the intake that runs across the top of the engine has 2 holes underneath that recirculates the air in the head back into the air intake. If I remember right, it won't run if those holes are exposed. I also think in the actual air tube that runs on tops of the engine, near the bend closest to the TA, there is complicated valving in the actual tube. I don't think it's hallow all the way...i could be wrong though.

[Andrew C280]

yah rocky your right.

[Rocky]

Lets take a different approach. Instead of trying to re-route the tubing, why not try to lessen the heat within the engine compartment? I know those headers give off a load of heat. Turbo wrap and a heat shield on the headers might make a difference. Maybe you can turbo wrap the air intake pipe as well?

Maybe route a intake tube on the TA side to cool down the intake manifold?

[Andrew C280]

this turbo wrap is fire proof ?

fibreglass matting,or turbo wrap is fire proof.well,everything has a melting point...

sory,its more heat resistant than fire proof to be politicaly correct.
