Karbonius CF reproduction of standard S54 plenum **PROTOTYPE VIDEO**

- carbon fibre trumpets will be fitted
- Karbonius opted for a flat top surface (versus the having humps like the OE plenum) as this provides a louder sound. They were also not aiming for an exact reproduction.

Thank you for all the hard work on pushing this forward! It's not often you see a new product being developed for an aging low production number car.

No worries and totally agree about this being an increasingly rare opportunity to get a new product for the S54. I'm really happy there were enough like minded people to get the numbers Karbonius needed to go this far.

Is production number locked on this; or is this still open?

I'm updating the EOI list, so I will add your name. As mentioned, this is not a commitment to buy, but the list is going to be handy to get in touch with people once (hopefully) we are ready to put in an order.

Done!

Can you convince Karb to improve the velocity stacks' size?

Is there a reason they arent going to make a maf CSL version

From their perspective, I'm not sure there would be much incentive. At the moment they can re-use the design and moulds they have for the CSL plenum and trumpets. If they had to redesign and make new moulds for the trumpets, the time and cost would go up. What would be your suggestion for changing the trumpets?

The idea with this design is to be able to keep the stock airbox and all fittings and not have to alter the tune. I think there are (or were) some companies that make a CSL-style intake with a MAF?

Not really possible.

Absolutely - I've added you to the list.

The prototype is now finished and Karbonius have provided new pictures. Fitment and sound to be tested next week.

Money in hand and ready to Karb!

I'd want to see a shot of the insides.

What do you want to see on the inside? The earlier pictures I posted show the insides?

This was straight out of the autoclave (it was still hot apparently), so I'd guess the trumpets weren't fitted yet. I'll confirm with them, though.

Do you need something else from me, let me know.

I was looking at the csl intake systems from other manufacturers. Many of them have increased the size of the trumpets for better flow. IIRC, cylinder 6 also has air inflow compare to other cylinders.
