Carbon fibre Pipercross indution kit?

[alz]

Anyone got one of these fitted. I just purchased an E46M3 and was looking on demon tweeks when I came accross the induction kit. It is pricey at nearly £900 though. The car I have has the CSL alloys, boot and bonnet and I was looking to upgrade the car slightly further.
If anyone has had it done, is it worth it?
Thanks in advance.

I think i'd probably rather go with the Gruppe M one.

DaveF kit available from www.e36coupe.com. He does a variant for the e46 as well. Brilliant stuff. Big K&N filter is what is used but the main thing is the hand-made heatshield. Having something in Carbon fibre does nothing for performance, it's just expensive.

Nice way to kill your Air flow meter that.

What with a K & N?

I dislike them intensely. 50/50 chance any car that comes through my place with a K&N filter will have a fecked MAF.

Not worth the money for little or no gain just noise and an "ooh" when you open the bonnet.

The oil on a K&N mists over the MAF which inturn burns the MAF out as these get hot, so you end up with incorrect readings given to the computor and can end up with low power, wrecked MAF's and engine management lights on.

Not recommended in my opinion.

Well that's the fist time I have heard that and I know that 00s of people have the DaveF kit on their BMWs. The kit has been dynoed (lots of times) with results worth between 12-15bhp on an M3 evo and I've never heard any problems associated with it. I've been running mine a year and all is well.

I will have my 8month old Simota for sale within the next 2 weeks if its of interest, probably circa £125.

I could well be interested in that Jason. Can you confirm it fits on an E46 M3?

Cheers

K&N claim 18.63HP@7400RPM which sounds very high... http://www.knfilters.com/search/product.aspx?Prod=...
On the oil mist damage I would have thought K&N would have done their testing on such a key issue?? is it cases of misuse sticking the filter str8 on after oiling up before letting it dry or whatever the instruction is???

[zmrjason]

Chessers,
Not sure if it fits an E46 M3. However Vixpy will know if you ask him!?
Jason

[Chessers]

Vixpy - I hear you are the man.

Do you know if Jasons Simota induction kit will fit straight to an 04 E46 M3?

Will PM you as well.

Cheers for the help on this.

[Vixpy1]

I'm afraid i'm honestly not sure, assuming the kit is orig off a Z3M.

[Chessers]

ha ha - I teed you up there!

I'll have a check about and see what's what.

My God french, that's not like you to provide something constructive

<thud>

I've read various reports on the effectiveness or otherwise of cotton filters. I have to say though that the report is hardly ground breaking. Does it not stand to reason that a filter that lets in more air will let in more dust?

My research into this topic has been quite substantial. I started out quite sceptical - especially so, when I read reports that a simple cone filter attached to some fairly clumsy looking pipe can release up to 15bhp, but countless dyno tests over on http://www.e36coupe.com have all showed the same thing.

And heres why:

The airbox - and therefore the inlet diameter, used in the E36 M3 is exactly the same size as that used in the E36 320 and all other 6 cylinder models. The chap who engineered the DaveF kit is an ex race engineer. He concluded that for what ever reason - most likely to be packaging, the airbox on the M3 was/is incredibly restrictive. The net effect of opening the inlet further allows more air in.

Now I don't doubt there is a correlation between knackered MAF's and aftermarket induction kits, but frankly, when the gains are so great, I don't much care! I change the oil every 3000 miles or so and should the time come that the MAF needs to be replaced then so be it. I'll perhaps keep an eye on the condition of the inlet tract, but I shouldn't think that my filter is letting in much more than the standard filter would as I don't happen to live in a dessert...

[Vixpy1]

I have no argument with the gains claimed, I'm sceptical natually, because i have not personally done a before and after the kit. But don't wish to debunk other peoples findings.

I also have no problem with aftermarket filters, they are usefull (though i personally believe no more that an uprated panel filter will do for most purposes)

My problem is oiled filters, there is no need for the filter to be oiled. And having seen VW's and BMW's running 14:1 Afr's with buggered MAF's, (which is not ideal), it is a problem. It rarely brings up an error code on many cars, its just lucky the ecu's pull timing to conpensate for the lean running. Because most people don't realise until they have a wide band stuck up the exhuast.

I think your right,not really worth the ££'s for the results you end up with.

I am thinking about fitting a the diff from a E46 M3 but I'm not sure whether I will have to cahnge the D\shafrt flanges or the prop flange, it seems to be the same casing?

This IMO is the most cost effective bang for your buck .

Pro's faster acceleration & mid range pick up

Con's lower top speed , higher revs (not to much) when cruising & ofcourse worse Mpg .

Two of the con's dont bother me at all ie Top speed it will still get about 140-145mph where can you go this fast let alone 155mph, Mpg i dont use every day so no problem , the higher RPm may be a pain though , depends what it would be at around 70 - 80mph .
