Hi all,
I come on these forums semi-regularly but have not posted before. I have a Z4M Coupe, so I mostly research, look at build threads, the dyno thread, etc, on here.
I'm not totally sure this should be in the GB section, so sorry if I've put this thread in the wrong place.
Anyway, over on zpost we are gathering expressions of interest in a run of carbon replicas of the standard S54 plenum, produced by Karbonius. For Z4s, we don't have the option of running a CSL MAP setup so installing a CSL-style intake means alpha-n tuning, which is good enough for some but not for others. So, the idea is to achieve some of the CSL intake sound, keeping the MAF and without having to adjust the car's tune at all. Of coure, it will not make any more power than the stock plenum. Some Z4 owners have Eventuri, Gruppe M, AFE intakes, but the hope is that a carbon plenum would add more on top of this. How much more, we don't know. For E46 M3 owners who have the option of going with a full CSL intake and MAP-based tune, this is likely to be less attractive, but I'm hoping there will be enough to get us over the minimum number of EOI Karbonius is looking for to make a test (20). We currently have 12 EOI from Z4 owners, so we aren't too far away. If the test plenum is a failure, then no one is committed to buying one. Pasted below is the information from zpost. If you're interested, please post to let me know.
Karbonius has estimated the price will be about 1,200 Euro.
To summarise Karbonius's reply, if we can find 20 people to express an interest in purchasing a CF version of the stock plenum, they will make a test.
"Hi Michael, thanks so much for contacting us with so interesting topic!! Isn´t the first time someone asking for this!!
Yes, we could do it, but there are any problems with this, the first is the coist of the molds!! an standar mold in GF only to make 20 or 30 pieces , could cost around 3000€, and then the pieces.. this is the first problem..
the second, is until we made the first unit we didn´t know what will be the sound, if louder or lower sound comparing with CSL, at first I would say lower than CSL, and this could be a problem, expend a lot of money on the mold and finally didn´t get the expected sound !!!
We could make a test, but we should have at least 20 interested persons in it!!"
