S85 Competition Carbon Plenum
Another step towards the M5 CS.
——

This is arguably the most difficult, challenging and rewarding product development since I’ve launched @euro.connex

I have goosebumps thinking about how far this pushes the envelope for the S85.

The specifications will surprise many.

You’re looking at one of the available trumpet design.

I will release R&D notes and insights on design choices here and on @euro.connex in collaboration with @infinitautodesign.

Keyword: modular.

The prototype is close to production in carbon construction to review, and document before release.

The first S85 members will get introductory pricing too good to pass up. You can get on the waiting list for the crowdfunding launch here.

Any performance benifits? Really after one of these
I hope its not possible it can split
Rough price range??

 

[sunghyun7]

that design is gonna gut the low end torque and power which e60 m5 already struggles with. don't do this

You know this - how?

I’d bring your attention to this being one of the available stack designs available.

Yes.

2,500 to 4,500$ depending on configuration. This will be modular and the ultimate version will have matching intakes and Alpha N tuning.

long intake runner usually kills low end torque. it's a safe assumption before you spend thousands trying to build this.

It’s already in production. Simulations already done. Modular stacks to achieve your performance goals already designed.

The S62:

well can't argue with e39 having a good low end torque. not sure if plenum design is the cause but best luck to you.

actually i had it backward based on top google searches. long intake runner is good for low end. short is good for top end. could be interesting. good luck to you.

The stock trumpets are really, really ****y. I do not recommend laying the trumpets out as you have.

Thank you.

The testing process will be transparent and technical data made available for all to make their own assessment on which stacks they want to go to with.

This stack design is one of a few that will be available.

The stock trumpets are indeed crap and were designed within the space restrictions of the 2x piece split airbox design.

ABS is about 4-5mm thick and requires reinforcement beams within the plenums, limiting space.

if this is going to be open inside the car has be alphaN, you cant have the two banks mixing air with mafs.

You’re correct! One version will be and will have Alpha N tuning packaged with it.

 

[ZiMMie]

Just a reminder to include an intake temp sensor bung for both larger opening decklid for alpha N tuning.

Good point

New development is exciting, hope it pans out with noticeable performance gains!

I hope so too. The complete Motorsport kit should give the most probabilities of performance gains.

I'm working on the 2nd information release right now with more insights into the specifications that will be offered.

 

[o2sys]

This is sure exciting regardless of the outcome just the fact that there’s still “parts” being upgraded and/or developed.

 

[Derived]

Very, very excited for this.

Future parts list continues to grow...

Interested! Matt, my 2c is that I personally would like to see some discussion re: durability testing in any upcoming info releases.

Infinity will be using tried and tested methods for the ITBs, notably CNC’ed fittings and the trumpets will most likely be ABS plastic and thicker than carbon traditionally used in plenums.
