V6 3.0 TFSI Eventuri intake system under development

[chrissurfr]

Hey guys - as most of you know - us RS5 guys love the system.....Eventuri is now working on one for S5 owners.....all sales will be handled by forum sponsors who sell Eventuri :)


See below...


With the success of our B8 RS5 system and buoyed from the great feedback and support we received from Audizine forum members - it's time we visited the B8 S5 V6.

Having learnt a great deal from the RS5 development - it was clear from the outset that this had to be another sealed system. The heat soak generated in the engine bay would simply negate and power gains from a free flowing filter system. Worse still - perhaps even reduce power compared with the stock system. Unfortunately many intakes currently available for this platform are open to heat soak - many have produced what seems at first glance to be sealed but on closer inspection do not seal the filter to the stock intake duct leaving it open to draw hot air in from the engine bay. Furthermore - open cone filters with heat shields also draw in hot air because the shields are not fully sealed and the cone does not directly draw in air from the duct. There is minimal airflow being forced into the duct as it terminates well above the grill.


The Stock System

Unlike the small stock airboxes in the RS5, the S5 airbox is a decent size which draws in air from the duct that terminates behind the front grill. The stock filter itself is cylindrical and so has plenty of surface area however the airflow path is not so smooth. Parts of the stock filter are shrouded closely by the airbox and airflow has to negotiate through several turns before ending up at the throttle body. Since the airbox is mounted to the chassis - the inlet tube has to be flexible to allow for engine movement - therefore contains ridges which are also not great for smooth airflow.


The Eventuri Design

As we did with the RS5 - the main component in our intake system will be our Patent Pending Eventuri filter housing. This provides a smooth transition from the filter opening to the inlet tube to maintain laminar airflow through the system. Another feature of our venturi design is the increase of gas speeds at the housing exit which allows for better throttle response.

Here is a diagram explaining how our filter housing is so different to anything else out there:



The effect this has on a supercharger is a reduction in drag due to the laminar flow which allows the charger to work more efficiently therefore resulting in more power.

Unlike many "carbon" intakes, we will be using 100% prepreg carbon fibre and plenty of it! Our housing will have a 2mm wall thickness which is unheard of in this industry. This means that the carbon will be a very effective insulator from the high heat of the engine bay.

The filter housing will connect to a carbon tube which will gradually reduce in diameter from the housing exit to the throttle body - matched at both ends.

Finally and perhaps the most challenging part is the cold air feed. This will be 2 components, the duct and the scoop. Our duct will connect to the stock duct and then smoothly transition to the circular filter opening of the housing. It will be fully sealed to the stock duct and again sealed to the filter housing. Finally a scoop protruding down from the stock duct behind the grill will force ambient air upwards and into the intake system to ensure low IATs.

Whats the expected price point going to be? I was on their website a couple months ago and they had intake systems for a couple thousand dollars!
I would love to buy their "cone" and strap it to my Roc Euro Intake.

[Mat@1975]

Hello Eventuri,

Are scoop extension and carbon scoop compatible with aftermarket cold front big heat exchangers ?
I worry about those pièces that will interfer with the top of the upgraded s/c hx .

Thanks in advance,

Verry interrested! But of course waiting for datas and pricing !!

Best regards

Mathieu

looks like single stacks are going to be close to $900-1000 since their double stacks are $2-$2,500 usd.
that's a lot of mod money just for an intake. design and weaves on their other intakes look solid though.

I'll be surprised if its that 'cheap'. They make beautiful intakes, but damn the price is crazy.

[RWD2quattro]

Too much $$, ECS intake and soon to be released 034 are better priced for this market.

PRM intake system... anyone remember those guys? I do...

[Low Flyer]

Seems interesting, if the price point is reasonable, this would be a nice system.

[doug97gxe]

if the HP is on point or better than the Roc-Euro and it keeps IAT's low it will be worth it, because its definitely a show piece like the ECS .. they also make engine covers, i'm assuming if the intake does well you could get a nice engine covered piece to match the colored carbon intake like the RS5

^Damn that's hot.

[4Rings3Liters]

Very interested in this. I was also curious why no one designed a dual intake for the 3.0. I thought I remember seeing one on a SQ3 that made good power.

because we only have 1 TB

[will13k7]

interested to see if you guys make more power from a closed system, so far with the 3.0T, open has consistently shown the largest gains.

[jmaddr]

Their theory is, yes, open element may make more power on a dyno with the hood open and fresh air getting to the element, or on a 1/4 mile track with a cool engine, in real world driving a closed system will remain more reliable with better heat soak prevention. This new system has the promise of increased air flow through multiple inlets, hopefully close to an open air, plus better prolonged heat soak rejection through a closed system.

i had the same question as Will http://www.audizine.com/forum/showth...er-development

but it goes a little more than dyno and 1/4 mile track, people in this forum have actually logged real world driving with the open air design and it showed lower IAT's

[s4matty]

Found this online
Took a screen shot of it! Looks sexy

I'm sure it will look good, but $1k with no performance increase over a $250 intake, no thanks.

and less sound from it than an open element, i like that sound lol

+1,000,000!

[CrownSeven]

I'll reserve judgement until the very least they release pricing and some data. If its under a 1K I'd probably bite. Its a beautiful piece.

i checked IAT's with both my p3 gauge and vagcom, here were my observations

the open air intakes actually idle and hover around the same temp as ambient (usually for me it's 1-2 degrees lower than ambient according to mmi)
this is the same with the stock intake on the car

if you say got stuck at a stand still or crawl traffic or went through a drive through for a quick mc donalds, you can see it going past ambient very very slowly ( 1 degree per minute ish)
the most it ever went was 8-10 degrees past ambient (86 degrees , ambient 76)

say traffic clears up , i drive at 40 mph constant , within 30 seconds, the temp goes back to ambient


stock intake did heat soak in traffic also , but it was +6 , never saw any more than that
also takes same time to get back to ambient

Hi,

Your IAT behavior seems very low compared to what i observed..
Is it with an aftermaket front end ??

You can't rely on the P3 gauge... Per conversations with P3 Cars reps... Their gauge currently reads the "ambient temp" NOT the "intake temp".
They plan on releasing a revised map late in the fall with additional features for more $$$.

this. plus the guys getting the best quarter mile times think open-element worked best for them. would be interesting to see a closed system that shows otherwise. I guess there could also be a system better for the track and a different system that's better for daily driving.

Given their current offerings, I'd say to expect a $1K price tag.

[chrissurfr]

its a great kit - they sold over 40 units in the rs5 forum and everyone loves it. the dyno numbers were no lie

For that $2K price tag, it should! If this has an intro price of under $1K (hoping sub $800s but wishful thinking most likely) I maybe game. If the gains on a N/A motor, like the RS5 is roughly 15-20hp, I could imagine the gains to be better on a force induced motor.

[Mat@1975]

Hello,

Yes, it could be interresting to show some gains, but not only vs. stock airbox/filter, but also vs. a competitor open intake.

Cheers,

Mat

[rwtzero]

Sub'd for proven gains over Open Air Element intakes.

[chrissurfr]

Update.....

We will be logging the intake system and stock airbox with VAG-COM to measure IATs and MAF values. The aim is to keep IATs low while increasing the values for airflow volume. We will also do some comparison logging for the IATs between the sealed design we have VS an open design (we will remove the duct which will expose the filter).

To enable the filter to breath better we have added a second air feed to the duct. This inlet is at the base of the duct to which we will attach an 80mm diameter flexi hose and guide it under the headlamp where the temperatures are ambient. This additional inlet ensures the filter is able to draw ambient air without the restriction of just breathing from the stock duct area.

Here is a render of the duct design showing the secondary inlet port.

That's not a fair comparaison.. a true open design feature a cone filter and a revised inlet pipe.

chris, do you work for eventuri ?

the secondary port is a nice idea. don't think anyone else ever thought of that.

$1000 for 3 HP..........

Provided the data given on the RS5 application and the fact that forced induction applications typically see bigger gains than N/A applications, I'd say this is good for atleast ~15 AWHP.
