Karbonius

RIP your inbox

You weren't joking 🤣

If anyone wants a Karbonius intake, I have one I am thinking about selling.
I bought it during the original group buy on m3f
It is "brand new old stock" as I used it as an object of art rather than putting it in a car
Moved a few years ago and don't have a good spot for it anymore, probably more useful to someone here than sitting in my closet.
I will eventually create a for sale thread but PM me if interested, might beat waiting till next January to get one.

PM’d

No clue how to price it, open to offers. I will create a for sale thread in the appropriate place but PM me if interested.

Will there be no more Karbonius CSL intake group buys? I would like to buy two, but I’ll be in less pain if I can get them at a discounted price.

Probably not on the airbox. It’s their biggest seller. They don’t need to discount it.

That insulation kit is offensive to the beauty of the cf weave

Can't say I disagree, was hoping someone had a pic of it to see how hidden it is or is not.

Obioban or anyone else who happens to be running the Race version with the built in snorkel. All weekend, I've been hovering over the buy button on the Karbonius site for both an airbox and a trunk (for the $500 in shipping of that trunk per this thread, I figure might as well get an airbox shipped).

MY QUESTIONS:
1. Are you running any sort of ducting to the box to direct cold air? Ian, you said you were just running ducting from the kidney grills earlier in this thread. Is it just the factory duct work or something more complicated / custom?

Reason I ask - it *seems* like with the "regular" Karbonius CSL carbon box that you could get cooler air to that box more easily, given the provisions that exist via ideas in this thread and others. With the Race version, the opening at the bottom of that snorkel is quite wide, so getting cooler air to it seems (again... seems) like it might be more challenging. If I went with the regular Karb CSL box, I'd use their carbon snorkel.
2. Is anyone running their heat insulation kit? Don't love the look of it, but seems like a really great way to mitigate some of the heat soak issues mentioned in this thread, in particular post #49 by Anri.

Sorry for all the hyperlinked content. Hoping they help others in the future researching this...

Speaking of which,

It is most evident when moving the car in first or reverse with little to no throttle (starts after cold start sequence has ended where the RPMs stabilize at 950).

Exactly.

[Slideways]

I don’t have that. I was willing to accept compromises such as that when first making the modifications but was pleased to end up with excellent low speed/low RPM behaviors. Credit needs to be given when credit is due which I mentioned prior.

Two of the cars were using a PCS tune, but it happened even with the stock CSL tune. With the MAF, they responded normally with a one up and down of the rev needle. The CSL has this two up and down as the clutch is engaged and it picks up after the second RPM surge. It is most evident when moving the car in first or reverse with little to no throttle (starts after cold start sequence has ended where the RPMs stabilize at 950).

Did you get a dyno tune and/or use AFR/datalog or simply a canned tune? I need to use BMWlogger and send some data to Hassan to see if this can be reminded.
Part of me wants to throw parts at it (TPS) as I will have the airbox off soon and would gain access the harder of the TPS's. I would like to at least test the TPS's with a multimeter if the values are known.

Eventually, dyno tune with AFRs logged on the runs. But really, the sessions benefitted the power pulls. I began with the tuner's 'base' tune which still reflects a lot development and years of tweaking. For the tuners here, it wouldn't be fair to call it a canned tune.

My view is this all falls under the category of some challenges (but addressable) that creep up when moving over to a CSL type airbox. I truly don't believe replacing a TPS or related parts will do anything, but as you know I'm at the opposite end of being an expert. Point I am trying to make is I have experienced variability across different tuners and then within those tunes, variability when a tuner changes a parameter or two, and well within the symptoms you experience. My journey was Kassel > FSTuning > PCS.

I don’t have it either, same tuner.
