Carbon Airbox for S50
Discussion
You mean like this http://img.photobucket.com/albums/v335/topwelshman... what do you want to know?
Taffy,
Bloody hell that is a setup! Yes that is exactly what I want to end up with. Couple of ways of doing it i believe:
1 - With MAF: easier to set up apparently & retains standard ecu(i have a unichip fitted as well)
2 - Without MAF: requires new management system, Alpha N or similar...
My choice would be option 1 providing good gains can be had. I am waiting for a quote for this. Apparently the MAF is not actually terribly restrictive so can be retained to simplify the whole process. The cars engine mods are decats,284 schricks,underdrive pulleys + full supersprint exhaust,ARP bottom end & UUC Comp flywheel.It would also appear I now need bigger injectors as my standard items are run ragged at about 6500rpm and so get a small flat spot before power comes on strong again to 8000rpm.
I think option 2 is perhaps unncessarily expensive for the additional gains it might give over option 1.
My questions are:
1, Where to source the best parts i.e. airbox + ancillaries,filter,injectors.....not sure what else is needed?
2, Who to entrust with the work of fitting and mapping etc?
3, I believe the driveablity will still be good? The car only comes out of its cover and garage for blasting about so don't need to use it everyday.
The car goes phenomenally well already but I just really think the airbox will really let the cams breath and make the engine more efficient and optimised.
Taffy, your thoughts please? Any advice/guidance most appreciatted!
Many thanks
Jason

The only reason to fit an airbox is for more air to feed larger cams, 284's aren't huge but big enough to warrant more air, I ran without MAF although this airbox is avaiable with and without and supplied by myself.
But if you are going mafless then you ideally should look at a decent ECU, DTA or Motec, then we're into big money, standard one can be remapped but there are other issues from what I understand.
As for the work, well there are a few that can map and know what to do without the MAF, Geoff Steel are decent and have links wiht mappers that can do this for you as do Butler Motorsport of Wrexham, wouldn't go anywhere else.
Your car shouldn't be maxing the injectors with 284 cams, we had this problem but ours had 296/296 and we swapped to Porsche GT3 injectors, standard Bosch items, I got them from Hinckley Valtone if I remember rightly, but they need new top hats making for them.
All this was on a race car mind you, for the road i personally wouldn't go this route, too much hassle and money, i'd spend the money on better shocks instead, Intrax or Moton, it'll be a bigger improvement

Taffy,
Thanks for your imput.
When you say "All this is for race use" and wouldn't bother for road/occasional track use......Are you refering specificaly to the MAF less Airbox or the fitting of an Airbox full stop?
Do you have any indication or feeling as to the cost of supplying,fitting and setup of the Airbox retaining the MAF?

Jason,
I'm in a similar position to you at the moment with an M3 Evo. Have got some some 284 cams being fitted next week and remapped and considering an airbox.
Have been looking into these a lot over the past few months and the general view (from owners and tuners) is that the performance gains are minimal. The airbox "completes the package" but not much else. The biggest gain you get (and if i am honest partly what i am looking for) is that CSL like induction sound.
The boxes can be bought starting from £250. This gets you a box from hong kong which does the job but needs a bit of work to get it to fit properly and the quality is as you would expect from a cheap copy.
The next step up is the Geoff Steel box. I know someone who has had this and is very happy with it. They have also just changed/improved the design slightly as well. From what i understand this seems to be the best compromise and at £695 is fairly priced (and probably the route i will go). There is a sound clip on you tube for one on an M3 and it does sound good.
After this you are into the world of big bucks i.e. £1100 upwards. These are the best quality and were similar to the ones used by the racers but come at a price. s14power.com are doing a group buy for these at the moment. Price is around 1500 euros.
Despite all this i am still undecided. I really would like the noise and think that there will be a small benefit in the performance but at the end of the day the car is a track car/weekend toy so not sure it's that important. Its a shame they are all so expensive but thats car tuning for you.
Hope this helps

Colin,
That reflects my thoughts exactly! I am going to make some calls and am waiting for some quotes¡K¡K
The one thing I will not be doing however is buying anything from Hong Kong, I have lived there and will not be buying anything at all from there for my car!! Make your own conclusions ļ
If you want to discuss buying together etc give me a buzz on 07768 664664.
Cheers,
Jason

I know what you mean. I spoke to someone who has a Hong Kong copy and his view is that if he was to do it again he would probably go for the GS one.
The good quality German ones all seem to be around 1500 euros but would be interested if you can find them much cheaper. I think at £695 the GS one is still the favourite. Will speak to them later and see if they are any cheaper for two or more.
