Breathing Fresh Air - Intake R&D, Part 9: Production

Posted: January 16, 2020

Categories: Jeep Wrangler JL 2.0L Turbo Performance Intake 2018+

As Ye tightened the last bolt on our intake production sample, we breathed a sigh of relief. Over a year of painstaking R&D came to a close with that bolt.

In all our years designing intakes, few have been as complex or demanding as our 2018+ Jeep Wrangler JL 2.0L intake. We've fought check engine lights, tested more variations than we could have imagined, and learned a lot along the way. But the time is finally here to see the product of our efforts in its final form.

Shortly after we finished our final design from the last post, we began production on a sample to test fit. This test fit is the final (and often the most crucial) step in the R&D process. It tells us if our design

As the Jeep pulled onto the Dynojet, our anticipation grew. Would the increased flow equate to more power, or would our pipe fall flat? We removed the stock intercooler pipe from the JL and installed our free-flowing cast-aluminum replacement. We strapped down the Jeep and fired it up.

Driving off the beaten path is a constant stride. Every throttle input and steering angle change is carefully calculated to overcome the obstacles in front of you. All it takes to break that stride is one misstep. A coolant temp gauge climbing into the red or a wisp of steam from under the hood is enough to take your focus off those obstacles and lock it on your dash. Suddenly, the challenge becomes cooling down your vehicle instead of making it to the end of the trail.

Overheating is an all-too-common occurrence for many Jeep XJ Cherokee owners. Off-roading is also an exercise in low-speed driving and for the XJ's outdated engine fan, it's an exercise in futility. When the XJ's 4.0L engine is churning at a pace just above idle, the archaic engine fan is barely moving air through the radiator. Low fan and road speeds, coupled with the extremely high load of crawling

At Mishimoto, we pride ourselves on considering the details. The basis of our development process is of course performance, but what really makes our products work for our customers are the details. Even in something as simple as our 2018+ Jeep Wrangler JL intercooler pipe, the details matter.

If you look back over the development of our JL intercooler pipe, you'll find a common theme: flow. We spent months focusing on flow and performance. We redesigned the intercooler pipe, 3D printed prototypes, and cast samples to test its performance. The result of that focus and work is a smoother and better flowing intercooler pipe. Job done, right? Not quite. We accomplished the big picture goal, but what about the details?

Over the course of R&D we heard a lot of feedback

As the weather grows colder here on the east coast, there's a collective smile forming on the faces of select drivers everywhere. Those of us whose engines come equipped with their own mini hurricane know this time of year as "boost season." The colder weather means denser air, and denser air means the turbos under our hoods force more air into the engine. More air means more fuel, and more fuel means more power. It might just be a placebo effect from driving with the windows down, the chill of the wind blowing in your face, and hearing the whoosh of the turbo, but fall to the driver of a turbocharged vehicle feels like Mother Nature loaned us a small piece of her power for the next few months.

The colder weather here in Delaware is also spurring us to finish our 2018+ Jeep Wrangler

The last post for our 2018+ Jeep Wrangler 2.0L JL intake ended on a low note. We had worked for months on our high-flowing intake only to find that it made the 2.0T Hurricane engine less powerful in the RPM range that counts the most. Instead of a torquey and responsive engine that made peak power at 3,250 RPM, our intake shifted peak power up to 4,500 RPM, making the JL feel laggy and sluggish. 1,250 RPM isn't a huge gap, but when most of your driving is done below 4,000 RPM, it can make a huge difference.

All was not lost, however. We looked back at the stock intake and found part of our solution. The branch resonators that we previously thought only affected the intake's sound appeared to play a much larger role in performance. A little research combined with our engineer's expertise

Our last 2018+ Jeep Wrangler JL 2.0T intercooler pipe post ended with our engineer, Jason, 3D scanning the stock JL intercooler pipe and engine bay. Over the next several weeks, those 3D scans would evolve into a digital drawing of our high-flow intercooler pipe, then make their way into the physical world in the form of a 3D printed prototype.

The prototyping phase is one of the most important steps in creating a new part. It gives us a true-to-life look at how our parts will fit and it's our first chance to recognize potential issues. It's also one of the most exciting parts of the process as it's where we get to watch our hard work come to life. With each pass of the 3D printer our ideas become increasingly real.

It's the challenges that make life exciting. Doing the same thing over and over gets tedious, but if you seek out challenges, life begins to get interesting. When we last talked about our 2018+ Jeep Wrangler 2.0L intake, things were starting to get very interesting.

The last post saw our prototypes hitting the dyno to see if our efforts had paid off. Despite a 20% increase in flow over the stock intake, there was no massive improvement in power with either prototype. Both prototypes did let out a little more sound from the turbo, however. While the lack of power increase wasn't surprising (as explained in the last post), looking at the resulting dyno graphs did show an unexpected trend. Though peak power didn't increase or decrease compared to the stock intake, it did move later in the RPM range. Much later.

Everyday Exploration - Oil Catch Can Kit, Part 4: Final Design

If you've ever started something new or made a momentous change in your life, you've heard some version of the old cliché, "Life isn't about the destination, it's about the journey." While I agree with that sentiment, anybody who's conquered a major challenge can tell you that, sometimes, the destination is the best part. There's nothing quite like the feeling of accomplishment you get from seeing something through to the end, no matter how long the journey is between.

When we last talked about our 2018+ Jeep Wrangler JL 2.0T catch can, we were just beginning our exploration and journey to a successful product. Our proof-of-concept kit had collected a substantial amount of blow-by on the CCV side but triggered a check engine light in the process. A quick look into the engine's computer

What's exploration without a challenge? If you drive the same easy trails or climb the same easy routes over and over again, life becomes boring. The thrill of exploration often hinges on the prospect of the unknown and taking a path without knowing where it will lead you. Without the challenge of the unknown, exploration is just following a map.

When we last saw our 2018+ Jeep Wrangler 2.0L catch can kit, we were still firmly in familiar territory. We installed two catch cans on the Jeep, one for the PCV side of the system and one for the CCV side. These two kits would serve as our proof of concept for each side of the system. At the end of our 1,000-mile test, we'd check the catch cans and see if we needed to build a kit for the CCV side, PCV side, or both. Before we could rack up 1,000 miles, however, an old familiar friend greeted us: the check-engine light (CEL).
