Real world intake testing. IE VS Eventuri VS Velocity stack off the turbo...

[VargasTurboTech]

So we love testing stuff here, its what do, and we enjoy the hell out of it. Our Shop RS3 currently runs an IE intake and were curious about the Eventuri intake as they make great products for many platforms. With this in mind, we ordered one up using our wholesale account and waited for it arrive. Once it did we looked it over, and man is this thing pretty. While this is not a review of the Eventuri intake or any intake for that matter, more of a performance test. The Eventuri intake really is second to none fit/finish, fitment, and quality. Just to have it upfront, We paid almost full price for the IE intake, and we paid close to full price on the Eventuri. This testing was not requested by EITHER company, and we never ask for free parts in exchange for testing. We just really like data.

So with all that said. Here is the basic rundown. We pulled the car onto the dyno this morning with the IE on it. Strapped it down, warmed it up and did a pull Ambient was about 63 degrees in the dyno room, it got up to about 68 when we finally had the Eventuri on, but that's still a close delta acceptable. We did 5 pulls for each, 5-minutes cool down between each down to the second. First, 3 pulls are hood open, last 2 are hood closed. When the noted all the numbers, an average of the first 3, and average of the next 2, and an average of all 5, and finally our final numbers used for which we think was the winner. Highest and lowest thrown out, an average of the remaining 3.

We chose to run UNCORRECTED on the dyno files. The temp delta was close enough that we wanted to show the exact numbers the car put down without the correction factors messing with it.

Once we ran the IE we pulled it off and ran a Blox Composite 4 to 6" Velocity stack right off the turbo inlet. NO Intake at all, this is for the people who insist that an open-intake pipe will pick up power. It would have been worse if we left the V-Stack off. This puts this to bed for everyone. Please stop with the why should I spend more on a close intake, my open intake or pipe off the inlet will make more power. Proven many times over, and here again. No, it simply won't. We included a graph showing the best 3 runs hood closed of all 3. Its a blood bath, no one should run open intake on these cars.

After that we removed the V-Stack, and installed the Eventuri. It took about an hour and a half we went slow, and we wanted to let the car cool a little to replicate as closely as we could the IE and Eventuri conditions. The fit and finish as mentioned was great. You do have to adjust things, which is why we had to abort the initial run 2 hood closed because the intake with thermal expansion etc moved away from the seal allowing hot air in. We adjusted it and re-ran. Also worth noting. After we did all this testing. I went back to work for a few hours, came back to a cold car, closed the hood warmed it up, and ran the Eventuri closed hood no heat soak. It made 560WHP hood closed so it matched its hood open power once it cooled a little. Very excited to see how it does in the 1/4 mile. We will get some runs this weekend. on the dragy.

A couple of notes, if you disagree with the testing or its methods that is fine, buy the intakes, and do your own testing, we are not here to debate the methods, we feel they are fair and methodical. Also if you see any errors please point them out. We did our best but sometimes you miss stuff. Also if anyone wants to see fair unbiased testing of the other intakes on the market feel free to send them our way. We are pretty much done buying intakes at this point the Eventuri is going to stay on the car. The IE is up for sale. $900

Without further ado, here are the results, and some photos, and a Video.

For a second I thought it was referencing the original Eventuri intake for the RS3, but that's the Stage 2 Eventuri intake. I believe Eventuri came out with a video showing no difference between both intakes until you reach the 700+ HP is when more gains are made with the Stage 2 Eventuri intake. Wish you had the original Eventuri intake to show if that is the case. Either way, cool data and thanks for sharing!

[allmotor_2000]

Excellent review! Only thing that may throw things off is air-flow with a closed hood. How much of a fan did you have blowing?

[VargasTurboTech]

Fan used is up there. It's a B-air high velocity almost 5000cfm fan. It moves quite a bit of air for its size. But it's def not going to replicate airflow into the intake while driving

[Ross_T_Boss]

Great work, and good data. I can't say I'm surprised, there's very little in it up top - until you close the hood on the open air stack! I would have liked to see some on-road data comparing those but understandably wouldn't want to run open air out in the wild! Looks like it's spitting hairs with IE vs others on the stock turbo, they can all flow enough, do you plan to re-test on a hybrid turbo? Seems a great excuse to throw an IMS850H on it ;)

[VargasTurboTech]

Yessir, our line of turbos for the RS3/TTRS wil be ready for testing in a few months. All mods we are doing to the car are leading up to testing those.

[Banny]

Would you ship the IE to the UK?

[joszer]

Do you have a baseline with the stock intake?

I would like to see a stock intake run with the snow filter removed.

[VargasTurboTech]

Can ship worldwide sir. But it will be more expensive than domestic.

Me too, I just found the old video from August but I missed completely the new version release

[FlyboyS4]

"Intake testing on a dyno" suggested for the title.

[S3DUDE]

Good information. The IE intake doesn't perform too bad after all, it appears to yield good results not just on your RS3 project but all across the board on the other RS3 owners cars. The quality/finish of the new Eventuri is incredible, it appears that the angles, the openings and the size/shape/location of the filters and pipes can squeeze more power and everything considered when finishing the product. $1700 for an air filter is baller. Can't wait to see if the $1700 will help on the drag strip or the draggy.

[Potshot]

Awesome post. Thanks for the data. I would love to see the uni intake in there. Vancityaudi did that comparo with the ie vs uni and got similar gains with a similar setup. I bet the uni and eventuri are neck and neck. Haven't seen much with the awe compared to anything.

[VargasTurboTech]

This is part 1. 60-130, and 1/4 mile testing up next.

[OE2]

I like what you guys did but i wish the velocity stack was maybe in a place where you would run an open filter. it's hard to see what value a velocity stack at the turbo would have on this kind of test. But i do recognize you guys have limited time to do all this stuff so nothing will be perfect.

In general i think most aftermarket intakes will perform similarly on stock turbo. And you pretty much proved that. Thanks again.

[allerum]

I mean the Vstack almost made the same with the hood open, So the open intakes would have the benefit of the fresh air coming in the box from the ram air. It seems without a tube the open stack doesn't have enough good air compared to open hood vs closed hood. So you proved that based on flow it would make about the same power until you close the hood cutting off some air to the stack. So we know the open filters give up some hp but is 10 hp worth $1200?+

Hood open the V-Stack made 10WHP less, and 11WTQ less than the Eventuri. Keep in mind this is NOT a single run calling it good. This is 5 runs with a very methodical cool down, and an average after throwing out highest and lowest. The Eventuri was tested when Ambient was about 5-6 degrees warmer than when we tested the V-Stack. A V-Stack if placed properly has advantages on a race car. But the point was to show people were saying an open-intake would perform as well as one of the more popular intakes. That was debunked quite handily.

Thank you for putting this together for the community. Much appreciated and very interesting.

Please do this test as well.

Unofrtunately we have no desire to test the stock intake. This is mostly being done in preparation for our upcoming turbo upgrades. We have no plans to run a stock intake, so there is no reason for us to test it.

[1FastS4.Com]

How does the Eventuri work with the large inlets? APR, Unitronic? Would need a stage 3.

[QuattroRS3]

I have the original Eventuri intake and went with the 3' Uni inlet and certainly felt the difference! I saw with the Stage 2 Eventuri intake that Eventuri themselves came out with inlet for it. Not sure if other current inlets pair up with it or not.

[S3DUDE]

Do you have a baseline with the stock intake?

I would like to see a stock intake run with the snow filter removed.

I ran my car a few times at the dragstrip with the stock Air filter removed to see if that would help a little bit with the trap speed and made no difference what so ever. I ran it with before and after and there was no improvement. That makes me think exactly what the Eventuri designed mentioned on his youtube video which is that the stock air box has too many 90 degrees bents(left to right, up and down) and doesn't help with a streamline air flow.

[OE2]

But the point was to show people were saying an open-intake would perform as well as one of the more popular intakes. That was debunked quite handily.

there is no open intake that is placed the same way you placed that velocity stack. I do not believe you debunked anything, if you placed your air intake in the same location as many/most open elements and got the same results then there would be some weight to your claim. Like i said, i appreciate what you did but it's important to understand the limits of what you can take away from the details you shared.

How do you like the Eventuri intake? I was thinking the original was called Stage 2 and latest Stage 3 but could be mistaken. The Stage 2 has the 3” pipe to the inlet while Stage 3 has the 4”. I would assume other 4” inlets work but good question. I have another thread started looking for Eventuri inlet feedback but not hearing much.

[VargasTurboTech]

Took the car out for some follow up testing on the Eventuri intake. Not disappointed. The car was a consistent 134-135MPH car before. Picked up a full 3MPH trap speed with no other changes. Nothing is a more accurate indicator of power being made than trap speed. The car is making more power than with the IE intake on it, no question about it. Also if you were wondering what's the most consisten tune out there. Take a look at this. 3 back to back runs, no cool down. ET dead even to the 100th of a second, and trap speed is identical in two of the 3. This is on the STREET not a prepped sure, no slicks. This car is the epitome of consistent right now.

The photo spaced out at the bottom is the previous best on the street, same location slightly better DA, 3MPH slower.

From what I recall the Eventuri intake was the first intake to come out for the RS3 and I ended up getting it to go with the MSS kit as my first mods for my RS3. I LOVED it when I first got it and still pretty happy with it! It's like car porn under the hood, you feel it during spirited driving and def sounds pretty good when giving it plenty of throttle as well.

You don’t want the tested intakes delta versus stock? Isn’t that the most important piece of data for any flash or bolt on product?

[gokchen]

I feel like stock vs aftermarket gains is more suited to the manufacturers of the intakes. That will show reasons why we (the buyers) should upgrade from stock. VTT is providing us great data and showing potential upgrade paths and how they are trying to maximize the potential of their car. They are essentially gearing up for their turbo offerings which I sure they will show stock turbo vs upgraded. It's nice that they are taking us on the journey and showing everything they are doing

Very good point. I’m sure the stock v intake data is on the manufacturer websites. I’ll take a look. Thanks

[Eat.Sleep.Race]

thanks for sharing, now to add UNI and AWE to this TESTING!!!!

[mullh]

Hi, you say you have gained 3mph on the IE? Seems to be a mistake, look at your graph of this run closely and you actually decelerate a bit at the end of your IE run. Seem actually to be almost identical the results.

Thanks for the testing and keep it up!

3mp gain with the eventuri. [Ie was slower in the comparo].

[Chris F]

1/8th trap and ET are basically the same for both intakes but the IE run has a weird dip at the end which makes it appear 3mph slower.

Is there an IE log without the weird dip? To me it looks like they are making the same power.

Great results BTW looks like the car could almost sneak into the 9s at the track on a slick.

Not following sir. We ran this car at least 20-25 times in the 1/4 mile on the street, and the strip with the IE. It never managed over 135MPH a single time. Usually trapping in the 134.5 range. With the Eventuri it trapped 137.5 consistently. This is not a single run comparison.

[Ross_T_Boss]

To be fair, Chris F is right. That Dragy run posted on the IE has 136-137mph all over it, clearly lifted just before the end as it drops. When I run 109mph in the 1/8th it always gives 136-137mph unless the DA is creeping up. Not to take away from your work, it's great to see the comparison.

I'd bet a swap and back to back run and you'll see it really close, the dyno results are great and I'd say there is few hundredths and maybe 0.5mph from the Eventuri. Which still counts for a good gain at that level - heck, that could get me a 10.0 on street tyres.

[mtwallace85]

I’d like to see the other Dragy runs of the IE intake in the 1/4 mile as there is clearly a lift at the end of the included run.

I’m guessing this is the stage 3 intake? The original Eventuri intake showed losses:

https://www.audizine.com/forum/showt...ronic-Eventuri

[VargasTurboTech]

Took the car back out for some testing with the slicks on it, and a little more weight reduction. No changes in mods, and no tune change. The car did not disappoint. Took it to the strip, and did some street testing this morning...

The difference in trap between the strip and the street is due to running MUCH less tire pressure at the strip about 8 psi in the front slicks compared to 25 psi on the street.
