Releasing the GR Yaris' Turbo Sounds! Eventuri Intake Development

With 3D Scanning complete it is time to design and prototype the Eventuri Intake System for the GR Yaris.
Lead Engineer Bilal Mahmood talks us through his design process, analysing the original airbox and showing how he improves the design, releasing not only the turbo sounds but also allowing the turbo to work more efficiently, creating more power.

Your detailed explanation of the R&D process puts you at the top of my list - well done and thanks again!

[@oneeleven9832]

Well I’ve got to say i had no idea how complex something like this would be..very professional 👍

[@zassmanpeter1543]

Nice design! :) But i asked myself, what would happen if a large amount of water hits the intake, as the stock airbox is designed to prevent the engine from sucking water in.

[@BloxKilla]

After 2 years, still no answer 🤔

[@maxtorque2277]

Hmmm. Unless you show the OE and revised system with the same scaling then we can't compare anything. What you find is that the filter acts in all cases as a very good dynamic lineariser, because it is effectively a very fine mesh of a lot of very small holes. Typical OE air systems are designed to a 1kPa dynamic loss for both dirty and clean ducting, so i'd be astonished if adding the revised system gave any (significant) gain on a std car. Sure, if you wind up the boost and significantly increase engine intake mass flow there might be a bit to be had, but modern OE airboxes are really good enough as you fluid dynamics model shows! You'd almost certain get a better gain from simply upping the diameter of the precompressor pipe (which is where the velocity is by far the highest because the CSA is the lowest) and because dynamic pressure is the square of the fluid velocity, any gains really only happen at higher velocity points, say above 80 m/s or so.

[@ilpatongi]

Thanks for having explained that manufacturers absolutely don't prioritize on performance regarding the airbox and a lot of other components in general.

[@MJ-GR]

I replaced the stock paper filter with a K&N filter and also got more turbo noise - but yours is much more noise!

[@samster1995]

Great work guys. Couldn't ask for a better video. Explaining the whole process from idea to prototype. I'm glad that i didn't skip any steps (except cfd and carbon) when i was making the airbox for old k04 2.0 tfsi. That rs3 poster in the video....right in the feels 😢

3d printing has really made product development a much quicker and easier process.

Eventuri was essentially born because of 3D Printing meaning it was possible to create a prototype to validate Bilal’s theory.

Mine arrives in 4 weeks... these ‘tech’ videos are really interesting. Not sure if I’m going to do to much to mine... the warranty at the moment is more important to me. Although I would love at some point to get some performance upgrades. Looking forward to see the Dyno results 😎

[@EvolveAutomotive]

You will not be disappointed I promise you that! For many the opportunity to have such a car with a warranty will mean they remain original, but we think there’s some potential to be had by refining certain areas. Dyno and real world testing is to come!

[@jakob1phelps]

Thank you so much for these kinds of videos! So nice to see what goes into these.

[@alanhillyard1639]

You are falling into the trap of assuming that disruption at the walls is a negative - actually this will energise the flow at the wall, reducing the boundary layer and increasing effective flow area. I don’t think the convoluted section is really an issue other than potentially being a smaller diameter, and certainly allows significantly more engine movement that your much smaller section seal. I’d be interested to see the seal on yours after 5 years in comparison to the OEM one, though replacing the seal at intervals would be acceptable if the rest of the system doesn’t become damaged

[@chrisg4rr377]

Thinking of the initial cost of the airbox, additional costs would really make you questions any purchase. Also when using a flow dynamics software, surely you would need to take into consideration the vacuum effect of the turbo pulling the air in, creating differences in airbox air pressure with different RPM and load application

[@charliebarge2693]

[@Dominari66]

I wonder if you could thicken up the airfilter section near the elbow and drop the whole curve that's still there and ram more airflow, without any angle. Definitely looking forward to the next video, I think the second deign will be the way to go, as the air going on gearbox won't be that much through the duct. Love this engineering episode, very informative, thank you guys.

[@peterwood2633]

I just changed FMIC, turbo inlet and charge pipe on my N55, transformed the car with boost coming on much quicker and holding 30hp more at redline Vs stock parts. Car feels like it's been tuned and makes repeatable power. Airflow does make a difference in some cars!

[@EvolveAutomotive]

Intercooler makes a huge difference on these cars as it is so undersized. It’s the same one used on a 320i 😂

[@chrismc1977]

Very interesting. With any before & after gains will you be sticking solely with intake development or looking at exhaust too?

[@EvolveAutomotive]

We will be looking at exhausts also, when some are available. With the removal of the OPF needed for any performance gains it’s sort of moot until the ECU has been unlocked so we can tune it.

[@aamirnajeeb]

Genuinely very nice video and well explained 👏

[@michaelmpagi1639]

Turbulence is good for air temps, small tubes slightly increase the air temp due to friction. Nice design

[@chrisg4rr377]

Air velocity, air turbulence, air temperature and flow dynamics all effect the air entering the engine. But in reality will it make any difference. It's not like its a N/A race engine, its just a small hatchback with a turbo

[@richardsedorski1206]

Wow you guys are very clever.👍👍👍

[@diyman25]

Very well design intake!!! Almost went over board for turbo charge car , I think in NA car will show even more benefits But I think my Gr Yaris intake will be this one :)

[@alanhillyard1639]

Decreasing resistance is always more effective in a TURBO vehicle because the flow is multiplied - any effect is also multiplied. Sure, you can turn up the boost to cover up losses but that comes with other damaging effects.

[@Eventuri]

Typically a turbo car will see more gains. As explained in the video manufacturers consider the airbox a silencer (I believe some OEM parts lists will even refer to it as such) and therefore are making a more difficult path to muffle noise. They then work the turbo harder to produce the required power. Unrestricting this intake path let’s the turbo work more efficiently, spool quicker and produce more power.

[@diyman25]

Eventuri yeah Turbo will make more power over any NA with good intake But still very appreciate the design guys did A peace of eye candy at GR Yaris engine bay A lot of ITB car need air box as nose reduce to pass some track day noise Really like the giant filter that incorporate I personally on all my track car I will put biggest air filter I can squeeze along with Venturi effect bell mouth ~ Can’t wait to drive my GR Yaris !!!!! And really looking forward to install the intake too

[@STEVEBHPDEVON]

Another brilliant video and very interesting 👍 👏 😀

[@MrDrivingFaster]

No intake looks cooler than an eventuri, but the are too expensive and the hp gains/cost is very low. Dropping an eventuri filter in the OEM gets you almost as much hp gains. I have a F82 and if eventuri was more competitive priced I would love to get it. Really looks beautiful

[@THE8END0fDARKNESS999]

There would certainly be fewer people willing to pay as much for a 31-37,000 car than for an RS3 (that costs twice as much) especially because the filter is oversized anyway^^

[@romka_ind]

Yup if the intake will cost more than 1k $ then it is defo to much for Yaris, but there are a lot of BMW and Audi owners out there to buy those intakes so no worrues for Bilal :)

[@EvolveAutomotive]

People said £32k was too much for a Yaris, but there's a year long wait.

[@romka_ind]

@@EvolveAutomotive 32k is a bargain for 4wheel drive rally car that weights 1280kg has a carbon roof and most powerful 3 banger on the market. People are all over the Yaris name not about what you actually get for the money, yes it is a lot for Yaris but it is not a Yaris. Toyota sell them not for profit but as Halo car. There are nothing even near to that price point that you can get. It is a budget car, a budget performance car. But that intake system is a premium product with expensive name, and price suits more Lambo, Audi RS and BMW M car owners nothing bad about it if you got a car that is more than 80-100k new, but too much for a cheap Japaneese car made for driving not for show off.
