New carbon fiber tube CAI available, retails much less than the Dinan CF CAI. Sorry for the crappy pics, I'm not much of a photographer.

Where can I get that!

I have a Dinan CF CAI.. do those come with the water baffle? Dinan now had those w/ their intakes.. My engine check light would come on in heavy rain due to the CAI collecting water... so you may think about getting one of those..

how much is it?

water in the intake..... not good


i don't have that problem and i don't use either the net or the watter baffle

So who makes it? How much is it? Is it 3" or 3.5"?

It is made by a company called Carbonio. The intake shown in the pics above is 3", I think a 3.5" is coming. Butt-dyno says there is an improvement, this is with a stock chip on my '95 M3, compared to the stock airbox. I recently removed my 3.5" HFM/K&N/PAR heatshield in preparation for upcoming mods, and plan on being at the dyno in the next week or so for some tuning. Providing there is enough time, we'll try to get a back to back comparison between the stock airbox and the Carbonio CAI. It is not as loud as the typical heatshield/open element CAI (noise I was growing tired of), but it will still scream at WOT in the upper rpm range.

I'll post an installed pic and pricing tomorrow.

Awesome! Can't wait to see/read more about this.

Where did you get that carbon fiber intake? and how much did you pay for it?

Yeah, I am VERY interested. My Dinan dealer can't get one anymore, even though they quoted me a price of $100 less than list on closeout. Oh well :rolleyes:

Here is their website www.carboniointakes.com although I can't get it to work :dunno

Here is a pic of the Carbonio intake installed

Whoa...that pic just blew my mind. The filter is installed in teh brake duct basically?? I must just be a retard in not having realized that with the Dinan ones. Hows the install on these types of intake then?

And oh yeah, whats the pricing like?

Pricing? it looks nice.

is the tube made completely out of carbon fiber is or is just carbon fiber layed on top of something else?

I went to that site, Carbonio, bimmer CAI is in development.
So how long?

I see them go for $260ish for the VWs. I would guess BMW systems would cost around that much.

It is all carbon fiber, afaik.

They are getting close, I have one of the development bmw intakes.

I'd guess a little more by virtue of being bmw application. :rolleyes:

Maybe I'm a retard here but wouldn't that mean one big puddle and your engine is vapour locked? Not good for people in moist climates like mine.

will these fit with ellipsoids?

It would have to be one deep-ass puddle to suck in water. The filter sits above the brake duct, not in it.

Sadly, I don't have ellipsoids, so I can't say. How much deeper are the ellipsoid headlights?

Thing is I've seen at least three vapour locked stock M3's up here, a bunch of E30 and other E36's and at least two Z3's all with stock air boxes. We get very heavy rains and the drainage sometimes sucks. Just something to be wary of.

I'm told by Jim Powell that those Dinan-style intakes can be made to fit with ellipsoids. There is typically some modification necessary to the plate that mounts it to the car just above the filter, and it's still a tight fit, but will work.

I don't like that flex section right before the MAF. Seems like it'd induce some turbulence, and the maf might not read as accurately. Dinan's solution of smooth coupling makes a lot more sense.

Yup, I have the Dinan CAI and it fits. Granted, its wedged in there (Good luck trying to clean the filter w/o taking out the headlight) but it fits. If the Dinan style CAI are the same way, I would see no problems. I didnt really have to mod anything besides move the CAI tube and filter around a bit.

really ? they had the cai on closeout ? i went to their website and saw nothing but camber plates, and carbon fiber engine covers for the E36 M3.

thats interesting, with this design you would think making it fit with the ellipsoids would be easier since the connecting hose is flexible. the dinan carbon fiber tube is molded in a way the position it fixed since its longer than this tube and the top end is bent to fit straight on the HFM, but it looks like if they make this a little shorter and bring the tube away from the headlights you can fit ellipsoids better

interesting, but i already spent my $400

I'm not particularly concerned. I'm also no so impressed with Dinan's hose reducer coupling either, the step down is abrupt, not smoothly tapered. But what do I know, nothing of fluid dynamics that's for damn sure.

The intake I have on my car is a development piece, not the final product release. Merely test fit it, which was perfect, and put on a dyno when time allows.

Hey Big Badmonkey,

You are holding out on me. I need one of those intakes. What are they going to cost and can they make them a bit longer to eleminate the HFM?

So when are we dynoing you car?

Vic

BTW I love your tag lines. Since I can't run them I am glad that you are. :awink:

There is nothing laminar about the flow in the intake when the engine is breathing hard. Assuming that you would want to keep it out of the range where the flow oscillates from laminar to turbulent flow the Reynolds number would need to be kept below 2000. Re # =(V*D)/U where V is the average flow velocity, D is the diameter and U is the Kinematic Viscosity. Assuming max flow rate of 340 CFM or 0.1605 m^3/s and an air temp of 20 C (68 F) U = 2.05 E-5. The diameter would need to be 4.9 m to keep it laminar.
Also with the larger air mass meter connected to the Dinan CAI there is no step down.
Cheers!

Sorry to get all nerdy on ya! :atom
The Reynolds number is a dimensionless quantity used in fluid mechanics. If the Reynolds number is below 2000 the flow is laminar or smooth, above 3000 it is turbulent or ruff. From 2 to 3 K it can oscillate.
Just pointing out that being worried about "inducing turbulence" with a step down or bellows is a mute point because the flow is well into the turbulent region. Not to say that either is a good thing!
Cheers
