Our engineering department has made some great strides in completing this catch can design as they have reached the final R&D stages. Overall strength and can rigidity were primary design goals for the kit, as we are aware of the rough and tough off-road lives many of these Wranglers live. We want to be sure that once you install this can on your car, it will stay put, no matter what rigorous environment you take your JK Wrangler through.

Bracketry starts with precise design and component fabrication. Our engineers had to be sure that our bracket would effortlessly hold our 2oz catch cans without any damage-inducing stress. In our last update, we left off with some of the cool tech we planned to use. The first tool we used was our FARO Design ScanArm.

This arm allows the engineer to literally paint an area with digital lasers into a computer file and any part that comes to mind can be designed within that area

Do you know the origin of the term Jeep? Some say that during WWII, these vehicles were referred to as General Purpose vehicles, and soldiers began slurring the acronym, G.P., into Jeep, hence its name today (there's a similar story behind the term Humvee). Others say that the name was derived from the popular cartoon character, Eugene the Jeep, from when the Popeye show aired back in the 1940's. Eugene the Jeep was a "go anywhere, do anything" type character, and interestingly enough, the US government had a contract sent out to several automotive manufacturers requesting a vehicle to replace the horse that was able to go anywhere and do anything. Are we going to try and debunk this once-and-for-all? No, I'm no historian. While there is still a lot of background I can go into there, this is a blog about awesome vehicle product development, so let's get to it.

We already know that the Jeep name is synonymous with utility. Their notoriety soared for being the go-to service vehicle during

Finally, the results are in! The testing of our 2010-2012 Cummins Performance Intercooler is complete. After months of development and weeks of testing, our team was extremely excited to crunch the numbers to see how our cooler compared to the stock unit. Before we jump into the actual data pulled from our dyno pulls, we will first compare the physical attributes of the Mishimoto cooler to the stock unit.

Intercooler Physical Comparison

First, our comparison of overall thicknesses of the stock and Mishimoto cores. This difference was displayed in an earlier post where we showed the actual measurements.

Stock vs Mishimoto intercooler core thickness comparison

As seen in the chart above, we are doubling the thickness of the factory cooler. Due to the design and placement of the intercooler, AC condenser, and radiator, we were able to expand this unit

Alright, it is finally time to see how our engineering team did with the development of this product! First, we measured the physical properties of the Mishimoto radiator compared to the factory radiator. Our first chart highlights the most common selling feature of a performance radiator: core thickness.

Mishimoto vs. factory radiator core thickness

We squeezed out as much additional core thickness as possible without causing any fitment concerns with factory equipment. The factory core came in at just under 1.7" thick, while the Mishimoto radiator measures 1.95" thick, making the Mishimoto radiator 13% thicker than the factory radiator. This additional core thickness allows our product to provide a greater fluid capacity and promote improved efficiency, which is reflected in the following charts. Our second chart shows the improvements made in

Time to see how efficient our cooler design is! We would be pulling our test truck onto our Dynojet to collect the data needed to evaluate the intercooler fully. Check out the conditions of our testing procedure below!

Testing Conditions

Vehicle: 2010 Dodge Ram 6.7L Cummins, Automatic Transmission, Performance Air Intake, Exhaust Modifications, Tune

Ambient Temperature: 70°F-76°F

Sensors: PLX Devices with Temperature sensors on both the intercooler inlet and outlet

Process: 6th^-gear pulls from 1,800 rpm to 3,200 rpm, with 4-minute breaks between each pull

Variable: Intercoolers were swapped on the dyno to ensure conditions were identical between the pulls.

Check out a few shots of this truck on the dyno!

Time to install our prototype radiator into a test vehicle to make sure that it fits perfectly. Luckily, we were able to check fitment on the same donor vehicle we used for our last round of testing. Once the truck rolled into the shop, we quickly installed our prototype radiator shown at the end of our last post. Check out a few shots taken during the installation process!

Once we confirmed that the primary radiator mounting points fit perfectly, we installed the shrouding for the top of the radiator as well as the mechanical fan and shroud. As with any test fit, we checked critical clearances to ensure that hoses and electrical components

Our prototype intercooler is ready to go! Let's take a quick peek at what our engineers designed!

First impressions, this cooler is massive compared to the factory unit. Our engineers weren't kidding when they mentioned that the size increase would be significant. You will notice two dimples on the intercooler outlet. They are predefined spots for injection systems such as methanol, or for a temperature/boost pressure sensor. These bungs are not predrilled, but they provide extra material thickness for those who wish to drill and tap the port. Pretty slick! You can also see from these images that our core is a solid bar-and-plate design. Now, let's compare the core thickness of the factory intercooler to the Mishimoto unit.

Now that we had our project objectives outlined, we could bring in a vehicle to begin the first stage of product development. After checking with our local contacts, we were able to locate the 2010 6.7L you see below!

A big thank you to the owner of this truck! Take a look under the hood. This truck was equipped with some basic bolt-on modifications.

Once the truck was in our shop, we set to work removing the factory radiator. Our goal was to capture all critical dimensions on the radiator so we could use these data points to design our radiator. Additionally, we would be taking measurements on the vehicle to ensure any enlargements we made would not interfere with components on the truck. Check out a few images of the factory radiator

Time to design an intercooler! Our first step toward this goal was to remove the intercooler so we could collect all the data points we needed. All front-end components were then removed from the truck to provide access.

Once we had the factory intercooler out of the truck, we set it up on our CMM table to grab all the dimensions we needed. Using our Romer  arm, we can collect critical points in a controlled environment and use them in Solidworks to develop a prototype. Check out a shot of this intercooler being modeled!

Once we collected all our points on both the intercooler and the body of the vehicle, our engineering team set to work designing
