Breathing Fresh Air – Intake R&D, Part 4: Rapid Prototyping

Sometimes the long road is the path we take when we want to slow down, take a deep breath, and enjoy the view. Sometimes the long road is the path we take when we want to do something well. While we love watching the development process unfold, we’re taking the long road to our 2018+ Jeep Wrangler JL 2.0T performance intake for the latter reason.

“Quality over speed” is our motto for many of our projects, but in developing complex intakes like the one found on our JL’s 2.0L Hurricane engine, it’s a requirement. Rushing through a project like this often means fighting check engine lights and poor performance. In the end, rushing takes longer than doing it right the first time.

We’ve spent the last four months analyzing every detail of the stock Hurricane intake. Our engineer looked at what was important to keep and what we could improve upon. We learned how the stock intake flows and which components affect that flow the most. In our last post, our engineer, Ye, took that data and added some creativity to render a 3D model of our high-flowing intake.

We’ve taken the best of the stock intake system and removed the resonators and corrugated couplers that hinder flow. Our intake will keep the lower airbox to help draw in cold air while maintaining the JL’s water-fording ability. A custom-designed upper airbox, filter, and tube will replace the stock components for better flow.

A 3D model is a great start to any product design, but the next steps are where things get exciting. To test fitment and performance, we need physical prototypes.

For cooler prototypes, we often call on the skills of our fabricator, Mike, to create an aluminum core then add 3D-printed components to finish it off. But this intake would be a little different. The complex shapes and need for precision made our 3D printers the only tools for the job. Mike may be a master of all things metal, but our drafter, Josh, is an artisan when it comes to 3D printing.

While it may look like a click-it-and-forget-it process, 3D printing functional prototypes requires a knowledge of materials and processes that many never realize. After receiving the part designs from Ye, Josh carefully selected the best materials for each component and tweaked the printer settings for the best prints. After many, many hours of printing, our prototype intakes were ready for assembly.

It’s nice to see you guys really taking your time to do it right instead of just slapping something together just to get something out on the market.

Any eta on these?

Any eta on these?

We still have quite a bit of R&D to do on this, so we're aiming for late summer or early fall of this year. Like we said, it's a long road, but we want to get it right

Thanks!

@Mishimoto any preliminary dyno numbers? Just ball park.

To be honest, the outlook for making power with just an intake on the stock tune isn't great. We've found that most modern vehicles (especially turbocharged vehicles with complex fueling controls) target a specific torque output at a given RPM and will adjust fueling, boost pressure, etc to meet that number. In these cases, almost nothing you do to the engine on the stock tune will produce power at the wheels. With that in mind, our main goal for this intake is to flow more air and remove that bottleneck from the system so that when there are tunes available, you can make the most of them with a more efficient engine. The extra sound of the intake will also be a nice perk, so we'll do our best to emphasize that as well.

We'll have more info on our testing and how our intake performs compared to the stock intake in the next post, which I should have for you around the end of the month.

Let me know if you have any other questions!

I'm in for the sound and added potential. If a good piggyback tuning device like JB4 or something comes along that I trust that will up boost and a few other good things, this intake will be what allows the most potential...and a good downpipe..

Yup! A good exhaust system will also be important. We haven't really looked at the stock JL exhaust to see how efficient it is, but the more air you can get out, the more you can get in

Thanks!

Thanks for the answer. There’s racechips out there that can be tested with also suoerchips will be releasing theirs soon. That should be a staring point for CAI testing.

Breathing Fresh Air – Intake R&D, Part 5: Prototype Testing

​

We’ve reached a massive milestone in the development of our 2018+ Jeep JL 2.0T intake. After months of measuring, testing, printing and waiting, we finally have a functional prototype. Although it’s been a long road to get to this point, the development of this intake has also been a breath of fresh air; we’re trying a lot of new techniques and exploring new R&D methods. But before we jump into what’s new, let’s look at what brought us to this point.

We began developing our intake by looking at the stock intake. Our engineer, Ye, filtered through all the components to find what needed to stay and what we could improve. She 3D scanned and meticulously measured every inch of the stock intake and the JL’s engine bay. Later, a flow-bench test of the stock intake gave us a baseline to compare our design to. With measurements, 3D scans and testing of the stock intake complete, we began building our prototypes.

To speed up the prototyping process and reduce the end cost of our intake, we utilized our 3D printers to churn out two different prototypes. One prototype utilized the factory turbo muffler, while the other replaced that section with a straight through design. We then installed both designs onto our JL to make sure both fit and no changes were needed. Any changes at this stage could affect the flow bench results, so it was important that everything fit like a glove before we moved on.

Finally, it was time to flow bench test our two prototypes and compare them to the stock intake. There was one problem, however. Our prototype air filter was a solid 3D printed part. Our flow bench data wouldn’t be accurate without a filter, and aside from drilling thousands of holes in our 3D printed version, there was no way we could pull air through the printed part. Which brings us to today’s update.

Outstanding! It is fantastic that you all do so much R&D compared to some other companies that just make a tube and stick a filter on the end of it. Thank you for being so transparent!

 

[Turbo_punkn]

Is it possible the custom air filter helped increase the airflow of your intake vs stock? Just curious what the numbers would look like using the factory filter for all the intakes.

The goal of designing our own filter was to open up flow and bring in all of the available air in the airbox so it definitely did play a part in the extra flow.

I'd have to double check with the engineer, but I seem to remember the stock filter not being super restrictive in our initial testing. However, by making the filter larger, we're able to pull in all of the air in the box, rather than just the top half that the stock setup can pull in freely.

The filter we made in-house is also the same shape/volume and material that will come with the intake, so the flow that we see here will be the same as the flow of the production intake.

Feel free to let me know if you have any other questions!

Thanks,

I think by far you guys have the most r&d into an intake than any other company out there. Seems most of the other companies just mold a straight pipe and slap a cone filter on and call it a day. Definitely can wait to hear if the muffler delete let’s you hear the turbo more.
