I assume there is an air tight diaphragm in your set up to keep un metered air out of the intake?
I think that is the cleanest engine bay I've seen in a long time.

A little bit out of topic (hope that is for this Last one Soundgenerator ok ? )
For all:

The very last sound generator is still available!

So this is (for the time being) the last one, since BMW could no longer give me a delivery date for two elementary components, let alone whether the parts will even be remanufactured.

330€ plus shipping world wide.

Shipping takes place on the same day upon receipt of payment.

Correct

I am glad I got one! I will be mixing the Carbon airbox + eventuri filter + this sound generator and I am sure it will be pure sex to the ears!!!

I'm in the same boat as you maupineda. I think if I hadn't been getting this intake that sound generator thing would have been a great purchase. I'm going to hold off getting the generator for a while so it would be good to hear your impressions. From its design I wouldn't imagine that generator would take in the sound from the box too much just the filter section?

I'm excited that the price hasn't risen too much and I can use their website to purchase which seems to give a good variety of purchase options.

It would have been great if the cost could have come down a bit given how many people were interested but its still great value for money as it stands.

Sounds good.

I got today two important informations:

1. BMW is able to deliver soon more pieces for my Soundgenerator 🍾👌

2. From 01. of october I have to sell all further Soundgenerators for at least 470 Euro. (Right know actually just 330 Euro + shipping).
Reasons are more higher materialcosts (ecspecially BMW Parts) AND I founded my own company today 😁
That means as well, there is the first shop (a lot of you will know that, but right now I still have to be silent) it will list my products in the next weeks.

MBan · 09-20-2022, 07:23 PM

Karbonius has just confirmed production starts next week. The price they have provided - 1,280 Euro - is a once-off for people on the list and will subsequently be $1,395 Euro. You will need a unique coupon to get the introductory price, which will be entered when you order on their website. I will send Karbonius the list and they will provide the coupons, which I will then send to individuals.

I've tried to contact as many people as possible who previously expressed an interest and I'm pretty sure the list is up-to-date but please check:

https://www.zpost.com/forums/showpos...&postcount=150

Delivery dates will depend on how many people place an order. As I understand it, you can make x plenums from one mould before it breaks or becomes unusable. So, depending on numbers they may need to make a second mould, which will take some time.

Following some conversation in a thread about why all CF intakes don't use the MAF, I contacted Karbonius to see if they would be interested in making a carbonfibre replica of the stock plenum. Below is the response I received from Karbonius. Because this would be a direct reproduction, there would be no power gains but the intention is that it would provide some of the CSL intake sound without requiring a tune or deleting the MAF. Karbonius (and Eventuri) have done a similar thing for the S65 and it sounds great.

https://www.youtube.com/watch?v=pjQ256lcHGA

I am waiting for a rough cost from Karbonius. EDIT: 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. If you are interested, please post in this thread. I'll cross-post on Z4-Forum and feel free to post on other relevant board (e.g. E46 M3).

"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!!"

Any News?😁

PayamFSU · 09-28-2022, 10:50 AM

Never got the email with the coupon , has it been sent ?

MBan · 09-28-2022, 04:42 PM

Sorry - I passed on a few more questions to Karbonius, which they are addressing.

One person asked if forged carbon is possible for the plenum, with the answer being 'no'.

Another person asked if it is possible to test the plenum to make sure it doesn't result in a loss of power, which Karbonius is going to do.

A few people also wanted someone to test the plenum before buying and Karbonius thinks that's a good idea before making it available. They will send the first one to me and I'll test and report back.

Jdmaflac · 09-28-2022, 11:53 PM

So excited to hear that they will be doing some dyno testing and love the idea of you getting a product to review.

I'm not sure - I haven't had an update from Karbonius for a few days. Perhpas they will wait until after they have tested the plenum for any power loss?

I'll definitely update the thread when it ships.

Polarbert · 10-08-2022, 03:05 PM

Hopefully not too much longer to hear something. I keep checking the thread daily for updates lol.
