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

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!

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.

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

Mishimoto joined the diesel world around 16 months ago, and since that time we have been providing unmatched cooling protection and performance for Powerstroke, Cummins, and Duramax engines. Using our knowledge and experience in the development of products for sport compact and European vehicles, our team is able to design, enhance, test, and manufacture a variety of beneficial components for your truck. We already carry a slew of products for Dodge Cummins trucks, including the following:

• Aluminum Radiators, 1989-2009
• Performance Intercoolers, 2003-2009
• Silicone Radiator Hose Kits, 1994-2010
• Factory-Fit Silicone Intercooler Boot Kits, 1994-2012
• Aluminum Intercooler Pipe and Boot Kits, 2003-2009

We currently carry a very full product line for the third-generation Cummins. Once we had that finalized, it was time to turn our attention toward the fourth
