Installing a cone filter..

[neelsie88]

I am sure its possible..

I have seen the front piece from a E46 fitted in a E36:

The intake piece thats above the radiator..


Then you could fit the Airbox as well I am sure..

And comparing my E36 to the E46.. I dont see why not..

E36:

The only thing is on my E36, to replace the AFM with a MAF & have a chip fitted would yield the greatest gain in power..

But for a 4cyl I do not think its worth it..

I do not know how the E36 6cyl engines look though

---

The fact that my 2 cars engines are similar would make it easier..
the E36 is a M40 & the E46 is the M43..

Here is a pic of a 6cyl

You can see where the intake for the airbox on the E46 is used as the cooling feed for the alternator on the E36.With a bit of modification it may be possibly to fit the E46 box...ie take another route for the cooling feed for the alternator

www.signaturemotoring.com Less than R1600 with an epic heat shield and a K&N filter. Thats what I will go for when I have the money.

Have a look at the pics on the right hand side,check where the kit meets the expansion bottle...Its doesn't look like its blocking off the heat that will be emitted from it(that's not good)...The Dave F uses this filter http://www.knfilters.com/search/product.aspx?Prod=RU-2590 Its much bigger than the K&N57i one.....


@ Moranor yes now that I have a Dave-F it looks like his heatshield could be knocked up cheaply :thumb:

http://www.knfilters.com/search/product.aspx?Prod=RU-2820 that is the one signature motoring uses according to the guy I am contacting via email.

If you are looking at the pictures on the main page they arn't E36's thats a E30 and E46 if Im not mistaken. I will email the guy to see if he has pics of it in an E36.

here is the photo I received from my signature motoring contact. and his reply on this kit versus the Dave-F kit, Ive looked at images for the dave F kit and I totally agree with him about the insulated edge (Although I dont believe the Dave-F kit is bad, Just not as good).

Signature Motoring makes the best heat shields bar none. Out
of curiosity I looked up a video purported to be a Dave-F heat shield. You must
understand the presumably common sense issue of adequate and pliable trim around the heat
shield. Due to the contours of the underside of the hood, no small 1/2" of trim material
will suffice. Secondly, the "Dave-F" shield appears to end prior to reaching the front
of the engine bay (the leading edge can be seen ending alongside the coolant reservoir,
over 1" from the front of the engine bay).

The Signature Motoring heat shield meets the front of the engine bay with ample trim
insulation at the leading edge. I have attached a file photo. No improvement can be
made upon a Signature Motoring heat shield either in design or materials - or we would
have done it.

Lies, just from the pic I can think of at least one way of improving the heat shield in term of both design and materials.

And Im sure you can get out of a locked and chained fridge suspended in the ocean and guarded by sharks... But we cant all be houdini now can we?

That is always a possibility I was thinking of passive changes.

I'm actually interested in what improvement you are thinking of? Maybe it's something I can DIY afterwards.

 

[Sankekur]

In term of design I was thinking making the heat shield double walled with a air gap between the walls, in terms of materials the gap can be fill with a material that has a very low thermal conduction.

Making the heat shield out of a ceramic material would probably work the best, but wouldn't be cost effective.

Cost effective or not im not sure its necessary. The heat shield does a very good job at enclosing the air. And I doubt the shield will get hot enough to heat up the enclosed air before It is sucked in.

What Sankekur says :thumb: The Dave F has a world wide reputation as been the best...The Dave edge goes into the sound proofing on the underside of the bonnet ensuring a tight seal against hot air getting in and Dave uses a better K&N filter than the Signature model does...He also seems to appear to have not heard of a Dave F....:mmm: Still end of the day you will go with what you want...I will stick with whats been proven

 

[Joefer]

it was easy on my E46 330i.. 5 min job!!
I will have to take pic's, throttle respons is much better and sounds awesome!!
Hope you get it right!!
My car was last on dyno on 134kw on wheels and 309nm

Each to his own. Filters can always be changed so it's the heat shield quality and design that made my mind up.

Fair enough Dave-F still has a reputation for having the best heatshield made too....

I'll believe that if you prove that the people that tested it, tested the Signature Motoring one as well. on the same car of course. But I also suppose it eventually gets to a point where subtle differences in the heat shield dont matter, all depends on how fast you're sucking in air and other related things.

Yeah I am not sure if it would make any appreciable difference, but the point still remains that they can't just go and say this is the best design material period, it might be good or optimum but not the best.

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

You could take it one step further and have a vacuum between the two walls.

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:

That will definitely not do... We need the vacuum to clean.

Uh, okay... :thinking:

I meant you could have a vacuum (or a void) between the walls of the (double walled) heat shield... This would reduce heat transfer.

lol. I know. Just kidding.
