Eventuri Intake for G80 M3/G82 M4 - Dyno Figures + Dimple Technology + Carbon Fiber - Part 3/3

Eventuri Intake for G80 M3/G82 M4 - Power Gains + Dimple Technology + Carbon Fibre - Part 3/3
After a few months of rigorous R&D Bilal is finally ready to unveil the finished Eventuri Intake System in Carbon Fiber for the BMW G80 M3 and G82 M4.
He runs you through the final design, taking a closer look at all the ways he has pushed the design to leave no stone unturned. This includes a visit to the classroom and explanation of a new technology that Eventuri are using for the first time in an Intake, an industry first.
Finally we get to see the performance data from the Intake System itself, BMW gave Bilal a challenge here by designing a very functional system, but through his experience managed to improve upon it even further.
To wrap things up we get to see the production system fitted to the car.

This is literally a free online masterclass on aerodynamics engineering. Thank you Guys so much for your in depth knowledge and your ability to share information without fear or malice.

[@Eventuri]

We are never afraid to stick our heads above the parapet.

[@harveynumber1]

Bigger internal circumference reducing to OEM surely means more friction and a greatly increased IAT?

[@amygdalohippocampus]

@@harveynumber1 Look at the equation for Pouiselle's law - length is in the numerator, so a longer tube at a smaller diameter has higher resistance to flow. More practically, imagine blowing through a really wide hose with a tiny outlet versus a really tiny hose with a tiny outlet. A lot of the stuff about "no one else has tried this" is ludicrous - every aerodynamicist knows about freaking dimples. If he's figured this out before F1, he would be making millions and you'd see it across the paddock immediately. Cycling engineers figured this out decades ago, for starters. But he's right about the circumference thing.

[@amessad]

Finally !!! I am taking delivery of the car on Monday and I have already ordered the intake... as soon as the break in service is done I am installing it! Greetings from Athens!

[@Hcarmad]

The level of detail, the clearly explained engineering and data is first class. Keep up the good work guys.

[@imoutofyourleague4299]

These in-depth videos are absolutely elite guys 👊

[@gouldnj]

Nothing to do with this intake, but I have your intake on my 2021 RS6 and just installed another one on my GLC63 today. Bilal, you and your team of craftsmen are mad scientists! The workmanship is stunning! This Mercedes intake is breathtaking! I questioned spending $2900 for it, but there is no doubt where the money went. Just stunning.

[@kenbias3523]

Bilal...You are the MAN!

[@Eventuri]

😁

[@RakwanTWOFOUR]

Oh my days I've never witnessed 43 mins gone by this quickly before. Wish this video never ended😅

[@jacobhauenstein]

this intake with some hybrid turbos would be amazing, I like the idea that you can simply design a larger inlet once larger turbos are available

[@Eventuri]

Yes we can easily adapt the diameters to suit.

[@BLX187]

Dimples inside air intake.. clever stuff.

[@dutchman9775]

I can’t wait to buy one! The fact that they will support 1000 HP is an added plus!

[@EvolveAutomotive]

We look forward to testing them at higher HP figures!

[@Airmattymat]

Have you tested it with high power people saying front mount are better for higher hsp

[@THEDOPEYDAISY]

I literally can’t get enough of these videos

[@proteinfart5017]

I love this I can say from having the intake system on my M4 cs that this is by far my favorite mod and looking forward to getting my hands on this new system.

[@anilbouri1485]

The detail and analysis is greatly appreciated. I always enjoy working on my cars but a technical explanation of the science makes it that much more valuable. As always great job and the effort applied is greatly appreciated. This intake will be great and I think will mean more to people if they take the time to watch this video series. Brilliant work.

[@mervyn2316]

Really enjoyed the longer style format of this video and how it went into all the engineering, well done on a great product!

[@michaelbetanzos6172]

Engineering masterclass - bought one today!

[@sumeetnandra8408]

A true masterclass of engineering at it’s finest. Really inspired me as an aeronautical student. 👍🏼

[@MrWesternDuke]

Thanks Bilal for a very clear and understandable explanation of a complex subject. Every day day is truly a school day!

[@pawilson1978]

Been a great set of videos. Nothing like a geek out with some extra innovation thrown in the mix. 👏💪🏆

[@stamatisvratsalis1480]

[@basschannelsa7155]

I literally learn something new everytime you upload a video Looking forward to the new performance figures after the install

[@nancylee7015]

I like all the information you on your intakes very in depth

[@samcas707]

Thank you for this, it was amazing. I’ve had eventuri intakes on my jag f-type r, f80 and rs3 stage 3. I have an rs6 perf on way and soon a g80, and can’t wait to grab eventuri’s for both

[@ryanmattson1735]

By far the best intake for the g80 on the market!

[@MitchTube]

I’ve worked on a few dimple projects. I was surprised how much testing and prototyping was required to perfect our application despite the engineering and simulation input. Awesome work guys

[@pwon]

absolutely amazing, as always

[@BMWDIYGuy]

Well done, your work is always just gorgeous and truly impressive.

[@johnmitman3922]

Fascinating stuff and will definitely be looking into the local dealer options!!

[@zloklau]

I love how in-depth this is. Thus is cool even I don't own any cars that fit the intake system 😂

[@JohnMartin22222]

We have come along way since my pipercross induction kit for my 1.4 Astra

[@arctica5193]

Massive thank you for this lesson. It is awesome to see, how you combine aero knowledge with engineering and advanced manufacturing to make a product on this level.... Do I have to metion, that you absolutely killed the looks??

[@knobstar67]

Complex stuff for Joe Bloggs, but I think you did a great job of explaining it, Bilal. Haven't watched one of your vids for a while so am happily binging now to catch up which, as always, appeals to both thr engineer and the petrol head in me 🤓

Amazing work again Bilal, I wish I was a bit better with fusion 360 or similar to make some custom intake pipes with those dimples for my car and 3d print! Thanks for the great content 😀

[@colin360cs]

Absolutely absorbing! Will never own a G80 M3/M4 and wouldn't spend the money on my B9 RS4 (it's a daily) and the weekend car is not a turbo but that doesn't stop me from being intrigued by the physics ...

[@padbender2972]

This F1 level of development...impressive.

[@bbkangs]

I have an Eventuri intake on my current car. One criteria for my next car is that I can get another Eventuri intake. 😁

[@dannylakatos5599]

Beautiful intakes and engineering. But i have to say, is the dimples worth the extra time/money to implement. Did you test a non dimpled vs a dimpled tube? If so, was there any significant difference? It sounds good and theory makes sense, but does it provide and real world increase in performance or temperatures? Thanks again for the video, very interesting engineering!

[@idbrown99]

Absolutely amazed at the sheer amount of unique R & D invested into the Eventuri G80 intake system. Could the dimpled panel technology be implemented into automotive vehicle panels to improve airflow, gas mileage, high speed stability, even for underbody panels...

[@Eventuri]

Potentially yes!

[@UnapologeticIslam]

Mythbusters (American science TV show) actually explained and experimented with this dimple theory and it was a success.

[@MrPocketRocket]

Fantastic product guys!! Very well done 👏 and the explanation of the process from development to the finished product was ace. The whiteboard session was fab too 👌🏼 I had two questions following the back of the video.. The stock intake seems to have a closer temperature delta between the two inlet feeds. The Eventuri seems to have one lower than the other. Is that due to the additional feed from the wheel arch area? And secondly will there be a version with a front mounted scoop as per the F90 M5? Thanks!

[@Eventuri]

The lower temperature is down to the more direct path and the material used for the inlet. On the left side. We will consider scoops as a separate part but this will require cutting away some of the panels.

[@liquidribs]

Beautiful masterpiece. Just a thought, what if we put smaller dimples in the dimples?

[@Eventuri]

Might run out of wall thickness 😅 I think that would just have the same affect of a larger single dimple

[@ianpreston1400]

How often do the filters need to be cleaned and are they easy to access ?

[@ericguntoro2256]

so are you saying that the dimple inlets only works if it has longer air intake travel? what if you apply that to the supra's intake the one from the headlamp (because its shorter to the turbo) does it still give the same effect or its less significant?

[@distance8677]

Beautiful product and in-depth video 😊 As always eventuri deliveres💪 Just a quick question why arent you developing any intakes for tdi engines ?

[@gregoryflinn3577]

... because they generate less power and so need less air? So the power gains are likely to be less, but I guess there could be other benefits as we see here.

[@Eventuri]

We just haven’t had the demand for Diesel engines

[@JayAllDayM3]

I love this intake and am debating getting this for my g80 xDrive. Quick question.. Is the air filter dry or oiled? Also does it need to be taken out to be cleaned after a certain amount of miles or completely replaced? What is the maintenance like? Thanks again! :) Also as an engineer myself I really appreciate this in depth video and the engineering and physics that went behind this intake! Cheers and brilliant job!

[@Eventuri]

Filter is dry and should be cleaned after around 7000 miles. You can use compressed air or a filter cleaner.

[@stefanroseEP3]

Would be nice to see ecu datalogs of the test car, i bet the ecu is doing it best to meet and not go over its torque targets.

[@EvolveAutomotive]

Almost definitely. We look forward to seeing results on tuned cars. Our xDrive M4 is arriving very soon and we will be going all out on that car so can do further testing as we increase the amount of air the engine requires.

[@dmc5681]

As always a nice looking product. How come the non-dimpled CFD does not have zero velocity at the wall i.e. as per the expected velocity profile? The dimpled one has higher velocity because the effective area is smaller as the velocity at the wall is lower due to boundary layer thickness. This is the opposite of your claims. Why not just tell us the difference in Mass Flow rate when the dimpled and non-dimpled are subjected to the same boundary conditions of a set pressure differential? Or flow them on a flow bench? Nothing you showed validates the dimples do anything in this application.

[@Tomoyo0827]

For people that don’t want the fluff: Power increased from *510-550hp @2000RPM* Torque increased from *650-750nm*

[@dmc5681]

these numbers seem way off what the graph says

[@franklinwatson7767]

If I'm understanding your comment, power gain of 40 HP at 2K RPM...Naw, you're not getting 40 HP from any intake, no matter how much it cost. Eventuri intakes will give the S58 good performance with upgraded turbos; not getting much of anything on stock turbos.

[@IamnotClarissaOakes]

Really interesting, thank you. I'm guessing a car with this kit would *need* a remap because of increased pressure at the turbo inlet and cooler air temps? Stock map must be based on stock pressure and air temp? Cheers.

[@EvolveAutomotive]

The results are on a stock car, stock software

[@Eventuri]

No need for a remap to benefit from the intake.

[@themindfulscientist7738]

I'm all for increasing air intake for my '23 M4, but I have questions. On a previous race modded production car I owned, I was forced to replace the custom air intake with the stock intake so that the dealership could run tests to figure out why my check engine light was coming on. They eluded to me that the increased airflow could have caused damage to the engine's intake manifold. Questions... 1. Will installing this Eventuri intake void or harm the manufacturer's warranty on the car in any way? 2. Does the car need to be tuned to handle the increased air flow? (tuning DOES void the manufacturer's warranty)

[@BlackFlag94]

Fantastic online learning lesson. Does this apply to all fluids? I work with water flow and I'm having some difficulty removing swirl, with a higher average velocity for a given pressure I should be able to smooth flow sooner.

[@Eventuri]

Higher density fluids will have a much higher Re Number so the principles will need to be adapted.

[@BlackFlag94]

@@Eventuri Thank you for replying. I'd need to do the sums for sure but it's something to keep going in the background. Keep up the fantastic work!

[@MrLIVELINESOLUTIONS]

Great content but what is the filtration efficiency? Is there a compromise made?

[@EvolveAutomotive]

Conforms to ISO 5011. www.eventuri.net/filters/

[@specialagentaustin4209]

Will you be implementing the Dimple technology on the F80 Intake?

[@Eventuri]

If we make the turbo inlets then it’s possible.

[@FastRedPonyCar]

When can we get some of this for the X3M? I feel like the F97 got kicked to the curb despite the same engine.

[@EvolveAutomotive]

Eventuri make an intake for the X3M, but the airbox layout is significantly different to the M3/M4

[@mikespeed3928]

Why not have dimples in the charged pipes as well? Why only in the Turbo inlets?

[@Eventuri]

Manufacturing method makes it difficult to implement.

[@stevegivelas9769]

I believe Porsche has been doing this with there intake manifolds for a couple of years now.

[@andrewrossnagel9433]

Looks beautiful. Nice to finally see BMW tuners finally use dimples in their intakes as IPD has been doing this with Porsche for over a decade.

[@Eventuri]

Yes they have used the concept but the way we have implemented it is completely different. As mentioned, size, shape and density play a crucial role. We have been able to fine tune the application due to the way they are made.

[@andrewrossnagel9433]

@@Eventuri it's not completely different at all lol. You're using the exact same technology and acting like you reinvented the wheel. Don't hurt your hand patting yourself on the back too hard. Next you'll put this on an aero piece and say how it's different from what Porsche is doing on GT4RS.

[@velhonen]

[@francischay8015]

Does this fit the x4m comp

[@EvolveAutomotive]

No, totally different setup. Eventuri have made an intake for X3M/X4M already.

[@nathandm1]

Looks like absolute garbage just joking🤣 what a stunning piece of engineering meets art!!!! I know it performs at its pinnacle but dayum does it look perfect!!!! Well done guys, bloody well done!!!!

[@Freshiemaster]

The RHS was quite different to the LHS. Any reason you didn't super impose that the RHS?

[@Eventuri]

Because the path and materials are similar between the intakes and so the improvement wasn’t as interesting to see.

[@Freshiemaster]

The RHS side intake, looking at intake temp graph you presented, stock looks to perform better than the Eventuri. I may have misunderstood however you didn't super impose so its difficult to tell.

[@Eventuri]

@@Freshiemaster The scales aren’t exactly matched on the 2 side by side. Temperatures were almost the same if anything the eventuri was slightly lower.

[@Freshiemaster]

@@Eventuri yes, but your review didn't highlight this, you only focused on the side that was an improvement. Looks like you cherry picked, however I don't think you meant too.

[@Freshiemaster]

@@Eventuri looking at the scalling the 2 sides looks very similar - I read across a few times. That's a bit counter to your suggestion.

Someone in marketing must have said bespoke is the word of the year. I keep hearing it from different part manufacturers. Kinda redundant to say this custom part is custom lol.

[@joejay2876]

So, for those of us who own the car, we are fully aware of the restrictions of the OEM air box design. One of them being the set of CARBON FILTERS that can easily be removed, resulting in obvious increase in air flow. Having said that. I would love if CAI manufacturers would compare their products against a carbonless OEM system to show their product's worthiness, instead of comparing it to an OEM system that is already twice restricted with one of the restrictions being easily mitigated by the owner. That is why I haven't spent a penny in all the overpriced CAI in the market up to now. Show a Dyno without carbon filters going against your product and then we'll talk.

[@EvolveAutomotive]

This is a euro car, and therefore has no carbon filters in the airbox. So lets talk shall we?

[@Eventuri]

None of our measurements with the stock airbox have carbon filters - across ALL our intakes. Maybe we should start adding carbon filters to pump those numbers up.

[@franklinwatson7767]

All this is great marketing, nothing more, the stock airbox on the S58 platform is actually real good. In the US, take out the charcoal filter and add high flow BMC filters and you're getting better performance than aftermarket cone intakes. Reality is, unless your going big turbo and building a motor, the only thing that grants the S58 performance, is a proper tune and down-pipes.

[@_ABC_123]

Great upload! Eventuri quality brand. G80 though still don’t understand why bmw had to make this iteration of the m3 so ******* ugly 😩

[@davestopforth]

You lost me at "this hasn't really been experimented or used". It very much has... repeatedly.... for four decades. Yamaha had a really good crack at it around the time they were doing the multi valve head investigations. Pretty much every time it has been investigated the conclusion has been that the Golf ball is the exception that proves the rule. The dimples are more often than not detrimental to airflow and often reduce the effective diameter of any given tube. But feel free to jump through as many mental hoops as possible to make the most of this dead end. Marketing is far more important than facts, right?
