RocEuro 4.0T Intake - Holiday Intro Pricing!

[John@Roc-Euro]

Howdy howdy everyone!
We moved to a new facility recently, which has allowed me to get back on track with finishing a pile of projects.
I'll get right down to it:

Some of you may remember our S8 intake prototype:

which led to this slightly derailed thread, haha


And I wanted to make the S6/S7 sound like this too.

Pardon the language, our local S6 guy is a riot:


So that's handled. I'll get more soundclips shortly, however on that same car, we just finished
wrapping up a little joint effort to get some new exhaust configurations into the real world:


Again - shorty clips, I know, but it's strange warm weather here during the holidays, so we're making do.
Full clips soon.



As for the details:
-Individual intake tubes per turbo
-Fully mandrel-bent 304L Stainless steel tubing
-Hard-mounted heatshield (no drilling or cutting, completely reversible)
-TWO full-size dual inlet filters, one per turbo (for reference, we use a single one on the V6T's making 430whp!)
-Fits factory engine cover, no cutting or trimming.
-Easy install
-Lots of turbo sound!

With the individual tubing per turbo, we matched the inlet length to each one. The layout on the 4.0T has both diverter valves discharge into the same turbo inlet pipe (that's the right side snail, or the 'front' inlet), so we intentionally angled that inlet pipe to point more towards the fender. Using our tried and tested bespoke filters (from the RocEuro B8 S4 intake), we know that the secondary inlet cone allows sound to pass back out in a straight line. In the videos, you can hear how prominent the discharge sound is. Of course, all of the sounds are going to be dependent on throttle, and load. This isn't some boy-racer atmospheric blowoff game here... It's quiet and demure, until you raise an eyebrow, drop the hammer, and remind everyone of what's tucked under the hood.

Naturally, the production pieces will be wrinkle black coated to match the existing engine bay plastic.
Should have the usual dyno charts after the holidays, just to confirm our internal numbers from the old dyno

I've got a batch on deck heading to powdercoat after this weekend - intro pricing of $449 shipped (USA) is underway!

All of the fun, on sale now.

Questions and comments, happy holidays to all.

What was the dyno numbers that you have so far? It would be interesting to do some intake temp testing with logging the car and measure the differences between the factory air box and the open filters.

In theory it should make more power. The whole piping and filter configuration looks great!

[mwmaroney1]

About time! I remember your company mentioning you were close to getting an intake months back, I sent multiple messages without getting a response. Hopefully it's all worth the wait, would love to see any sort of dyno numbers as well. Any way to get in powder coated in red instead of black?

[notn41]

Sounds good, doesn't look very high tech. Nor does it look like something audi would overlook for warranty.. Interesting idea though.

[Roccorace]

Looking good, can't wait to see the finished product pics.

Ive been running "another brand" open filter system through 4 S6's now. They dont care in service. Why on gods green earth would a warranty be voided because of an intake?

On another note, this one looks very nicely designed and wish I had this one instead of the one I actually do have.

Probably because that letter from Audi to dealers instructs them to manually slap the TD1 flag on cars if they see an aftermarket intake installed in the car.

Because it affects what goes into the engine, and manufacturers will look for any excuse possible to deny a warranty claim. Simple business.

On a different note, however, what about issues of heat with an open intake like this? Plenty hot in that engine bay.

Assuming this intake flows more than the original intake, a change in afr will result. Your car should be able to adjust to some changes, but if the change is significant your factory ECU may not have the correct tables loaded for the additional amount of air it is seeing. This in turn could throw a code, or worse, could cause your engine to "guess" the amount of fuel needed.
Too much fuel and you leave performance on the table...not enough and that's a big bill someone is gonna have to front.
Most aftermarket intakes do not change the dynamics on a system to that extent, but I assume Audi is playing the CYA game to ensure they don't front the bill for something their engineers didn't design.

Not to say people should, or shouldn't buy this intake! I love the looks honestly...and will be considering this once I am ready to tune :)

The sound is cool, but unless there is some performance gain what's the point. Def. interested to see the dyno numbers. Heat is always an issue with this sort of setup regardless of the machine it is on.

This is only true if the car has a Mass Air Flow sensor which I don't believe the 4.0TT does. It's airflow feedback is based mostly on manifold absolute pressure, which is post-turbo and minimally affected by intake air, so long as air flow into the turbo is not the limiting factor in producing boost.

Thanks! I should be cautious posting things as a fact when I don't know...

I'm coming from a very different platform. Thanks for explaining :)

Damn it! I just bought the AWE S-flo, who wants to buy it?

[playwithonehand]

Dear John
What make you go dual cone intake over single one, is it more cooler air and power?

also the position of the front cone does it make suck more air compare to the one behind thus one turbo cooler the other?


Thanks

Will this not heat soak like crazy?

Sorry for the delay, hope everyone celebrating holidays had a good time!

Yup! Although the standard will be fully wrinkle black, we will have the option for various colors.

Thanks to the "hot-V" layout, the lower sides of the engine bay stay relatively cool. Surprisingly cool, in fact. We still have a dedicated heatshield which directs air from the factory inlet, directly towards both filters. This also allows airflow THROUGH the area once it is past the filter area. After a spirited romp, you can pop the hood and touch the tubing. It's cool. Feel around the area and realize as you get towards the center, it gets toastier.

Dear John

A series of reasons, not in order, as its midnight on Christmas evening, haha:
-packaging: there is not a 'lot' of space in this bay. A larger single filter with twin inlets was my primary goal, but it made the tubing path kind of aggressive. A collector style merge with 2 into 1 for a larger single inlet filter didn't look the part to me because I wanted the smoothest flow into the factory turbo inlet pipe. The 'dual cone' reference is actually to our filter itself, as it features a cone downward into the center of the main filter body as well as the traditional shape. Offers more filtration area primarily, but offers great airflow in various entrance directions additionally.

...Also the position of the front cone does it make suck more air compare to the one behind thus one turbo cooler the other?

Nope, but I like where your head is at- facing the engine bay, your left turbo has a shorter runner than the right side turbo. Now this is all packaging because the intake is on a single side. The right side turbo has roughly 7.5" additional plumbing from inlet to turbine. So we made the left side turbo have the longer plumbing by the same amount. Essentially both turbos now have an equal filter to turbine length.
Does it matter? In practical application, probably not. But the concept of twin turbos having twin pathways is nice, and symmetry is great. There's was a comment about the set up looking not very high tech, but simplicity breeds efficiency, and efficient is effective. Plus like I said, by doing that, the inlet with the discharge pipes is the short runner, points at the fender, and makes great sounds.

[HyperM3]

We don't all have the advantage of selling audis and working in a dealership.

Nope, we all dont. However, as much as you think the dealerships are out to get you, they arent. Our service writers and mechanics dont really care if you have intake or exhaust mods or not. They dont get all giddy ready to slap a TD1 on every car that comes through the shop. Actually, most of them are enthusiasts like everyone here and appreciate what people do to their cars. I dont think there has ever really been a record of either one actually causing a case where a warranty claim wouldnt be approved. Im not talking about flashes here because that is what gets discovered by the computers automatically, so you're on your own deciding to do that.

[kouzman]

do you guys have more pictures of the intake?

[John@Roc-Euro]

I shall, couple days out. Just dropped it to powdercoat!

[ronbars]

Looking forward to seeing pics of the final product. How long is the introductory pricing in effect?

[madyspop]

I shall, couple days out. Just dropped it to powdercoat!

When will they be available to go out, also would there be a price break if I bought one unfinished? Thinking about having it Hydro dipped to a carbon fiber finish.

[John@Roc-Euro]

Madyspop, TBH I'd like to see that! $415 shipped, could be out the door raw, tomorrow. Email me: [email protected] if you're in and I'll create a promo code for you.

Another question: What brand air filters are you using? or are they your own production?

[John@Roc-Euro]

Another question: What brand air filters are you using? or are they your own production?

Our filters are made in the USA, to our spec. These are the same filters that we've been using on other platforms already; I like to design with consistency. Knowing the tested flow capacity, physical quality, and durability, we're able to ensure that things work the way they should. One of the best features is the dual-inlet cone layout:
(Seen here on the site)
Here's a shot from the Mk6 platform showing the direct inlet:


As you can see the images, there is a traditional pleated filter edge, and then there is also an interior section that offers additional surface area. It's excellent for airflow, cleanliness, and packaging. These filters can be cleaned via standard oiled-filter methods as well, making for a unit that you can replace easily, or update yourself on a nice saturday afternoon!

[mwmaroney1]

So I haven't received any responses to multiple emails or pms, maybe you'll respond here? I'd like to just order a unfinished one as well at this point, what do I need to do to get that going?

[John@Roc-Euro]

Ahhh my PMs never get passed through. That's being said, I've been on the emails, not sure what's up there. I'll hit you up via PM momentarily!

[CR8LUCK]

Same thing, have sent PM's. Do you have any tested hp increases, or temp numbers? Looks like a nice set up, but would like to see it be more then just a better sound.

that's good to know. post pictures of the complete product when available.

Then I will hit you up if you are interested to discount the intake for some testing. Rules are simple. 3 base runs on the 93 octane APR map with the factory intake, hood closed, back to back. Change the intake on the dyno, and then 3 runs on the intake, again hood closed. Dyno can be either a Mustang or a Dynojet. Of course we can have videos, dynocharts, etc. And I will pay for the dyno time, which can be 150-200 dollars...

[arrivalanche]

The unequal length was really making me doubt this product until you explained the extra .75" on the factory plumbing. Intake length does matter though fyi. Look at ITB setups. They can actually tune the car with the length of the intake cone. These cars may be smart enough to self correct with unequal lengths, but Id always error on the side of whats logical.

I'd be willing to send you my modified AWE airbox to compare it to the Roc Euro and stock.

I am not sure if it will be a good test for it. I see your signature shows an S6 and if I remember correctly the AWE S6/S7 box is smaller than the RS7. So if I would take you on the offer, I don't think I would be fair to AWE, testing their smaller box, especially on a tuned car which needs all the air it can get.

I will wait to see their final product and then we talk business.

Mine was modified to accommodate the RS7 Turbos and stage 3 S6. I already know for a fact (which was proven by a dyno) that the standard AWE box makes less power than then the OEM setup. After modifications (drilling holes to allow more air in) is when the power increased to more than an OEM airbox.

So... we should just drill holes in the OEM airbox?

Excellent question! Can you post pictures on how you modified the airbox?

At some point I am thinking of removing the top cover of the box for additional air (and probably sound) and leave the rest intact along with the ram air scoop and see of it makes a difference. And I think the modification is not permanent since the upper portion is held with clips.

[John@Roc-Euro]

Back in the office and I'll be responding in full to everyone.
Hope you all had safe and happy holidays.

[AstleyJ]

More sound clips?! Told my wife to order this for my Bday. Can't wait. Had the S4 version and loved it.

[John@Roc-Euro]

Working on it! We got slammed with some snow and 12*F today, and since we've had this 50* weather for the past month, I'm freezing lol. Should be at the Dyno Wednesday/Thursday as well.

Glad you loved the S4 intake, round 2 will be just as fun for ya!
