    Cool Under the Blue Collar - Radiator R&D, Part 2: Prototype & Production

    As the threads of the last bolt spun their way out, Jason hoisted the stock radiator out of the Ram's engine bay, over his head, and set it on the ground next to his workbench. With the radiator laying next to the truck, it was easy to see why we're making a replacement. The chiseled fenders and snarling grill of the 2017 Ram portray a truck built for power. The anemic core and plastic end tanks of the Ram's radiator, on the other hand, look like they come from a truck built to meet a budget.

    Dodge's most popular truck is not just a vehicle to get from point A to point B; it's a tool built to do what any tool does best: work. Like any good tool, much of the Ram's design focuses on reliability and its ability to take abuse day after day. You'd be hard pressed to find an engine more durable than the 6.7L Cummins turbo-diesel found in the 4th generation Ram 2500 and 3500. But despite its legendary reliability, the 6.7 Cummins still relies on some less than bullet-proof support to get

    Old Dog, New Tricks - Intercooler R&D, Part 2: Plans & Prototypes

    Tucked between the battery and the radiator, buried beneath a tangle of coolant hoses, lies the heart of the Ford Powerstroke 6.7L charge air cooling system.  This chunk of aluminum, the air-to-water intercooler, is responsible for keeping your workhorse breathing easy.

    When we looked at this project last, we outlined what makes air-to-water intercoolers different from your typical air-to-air intercooler and why they're used in heavy-duty applications.  We also took our waterjet cutter to our brand-new OEM intercooler to see what was going on beyond the bland exterior.  Once we had evaluated the stock intercooler's

    A Cooler Cummins - Intercooler R&D, Part 4: Final Prototype

    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!

    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.

    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!

    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.
