We are back with a much-needed update on our 13+ Dodge Cummins intercooler. For most of our projects, we work with a donor vehicle to conduct fitment and performance testing. Unfortunately, this also means being patient when donor vehicles are not available for us to use. The good news is that we will not have to be patient for much longer, because testing is on our schedule! Once we complete testing in the coming weeks, we will be sure to share the results with you. In the meantime we can take a quick look at our finalized prototypes for testing!

In our last post about the Cummins

Usually, when I write about our products here at Mishimoto, I'm looking for the underlying meaning behind driving.  Our performance intakes don't just let more air into your engine; they let it breathe as fast as you do when you're pushing the car to its limits.  Our oil coolers don't just keep oil cooler; they give you the confidence to shift a little later, to push the throttle a little harder.  Our products aren't just about what they do or how they do it; they're about possibilities and living a little faster than everybody else.  This time, however, my job is a bit simpler.  This time, I'm writing about our Dodge Charger Hellcat aluminum radiator and the point is clear: it doesn't blow up.

A Not-So-Peaceful Mind

You see, about a year ago, Dodge released a factory service bulletin (FSB) for "intermittent coolant weepage from upper radiator hose or radiator."  Yet, if you search

The factory inlet/outlet portions of this intercooler are quite interesting. They are shaped to route around the radiator support; however, this has a significant impact on the airflow through this part of the cooler. This bottleneck cannot be eliminated unless users want to grab the Sawzall and shred some steel. We will be looking

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.

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

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

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!
