  1. Old Dog, New Tricks - Intercooler R&D, Part 3: Flow Bench

    Old Dog, New Tricks - Intercooler R&D, Part 3: Flow Bench

    Intercooler design is a delicate balance of pressure and flow. Too much flow means that the charge air does not stay in the core long enough to transfer heat. Too little flow, and too much pressure, means all the work your turbo or supercharger has been doing is wasted on forcing the air through the cooler instead of into the cylinders. Heat transfer happens rapidly inside an intercooler, so it's difficult to make an intercooler core that has good flow. That doesn't mean we could use just any core in our 2011-2017 6.7L Powerstroke intercooler. Like all our products, this intercooler needed to be extensively tested before it finds its way into our customers' trucks.

    In our last post, we looked at our prototype with its 3D-printed end tanks and aluminum bar core. In this post, we'll test real cores with production end tanks to get the most accurate results.

    A Cooler for Atlas - Transmission Cooler R&D, Part 4: Testing

    This 2003-2009 Dodge Ram 5.9L/6.7L Cummins Transmission Cooler is now available! Click here to check it out!

    After all the time spent designing, welding, prototyping, and fitting, we were more than anxious to test the cooler and see if all our work would pay off.

    Testing wouldn't be easy though. The weather outside was growing colder every day, and cold is the enemy when you're trying to push the limits of a heat exchanger. Nevertheless, on-road testing would yield the most relevant results for our customers, so we had to try. We hitched a trailer to our 5.9L Cummins volunteer truck, loaded our 6.7L Powerstroke, and hit the road. Temperature sensors in the inlet and outlet of the transmission cooler would let us know when we had maxed out the cooling potential of the stock cooler. Once the inlet and outlet temperatures leveled out, we could record the final temperature and swap in our cooler to repeat the test. But the temps never leveled out.

    Comfortable Cooling - Radiator R&D, Part 2: Test & Produce

    This 2014+ Chevrolet Silverado / GMC Sierra 1500 V8 Radiator is now on pre-sale! Click here to check it out!

    Up until now, our 2014+ K2 Silverado radiator has been nothing more than a simple set of goals: create a direct-fit radiator that's larger, and stronger, than the stock radiator. After measuring the radiator and its home in the engine bay, we began working on our replacement.

    Like many of our products, this radiator started life on a computer monitor. Jason took his measurements from the stock radiator and created a 3D model that would serve as the template for our prototype. Once the model was complete, we could transfer it to our 3D printer to begin the rapid prototyping process.

    Form and Function - Universal Carbon Fiber Catch Can R&D - Concept to Completion

    In the world of aftermarket modification, there are two directions to go in with any upgrade. Form or function. Some might not care if the part looks like a work of art just as long as it performs, and vice versa. That's an owner's prerogative, and maybe driving around a box that hits the 300 whp mark and sounds like a grizzly bear is all you need. Other enthusiasts prefer a flashy set of wheels and a few want the best of both worlds, style and efficiency, which isn't always available. It's not easy to get that perfect blend. That won't stop Mishimoto from trying, though. We're aiming to create a little gray from the black and white of performance against aesthetics all while protecting your engine from blow-by.

    Next Generation Cooling - Transmission Cooler R&D, Part 4: Testing

    This 1994-2002 Dodge Ram Cummins Transmission Cooler is now on sale! Click here to check it out!

    Variables and constants - the two most important aspects of any scientific venture. For any test result to be accurate, a set of constants must be tested against one variable. The key in that equation being that there is only one variable. This concept becomes increasingly elusive as you begin adding more and more systems to the equation. Controlling our variables is a task we've become quite skilled in here at Mishimoto. After all, our everyday work involves testing extremely complex vehicle systems. But, we do sometimes meet challenges along the way.

    When we last saw our 1994-2002 Dodge Ram Cummins transmission cooler, it was installed on our volunteer truck and patiently awaiting testing. However, we had some decisions to make before we could put the cooler through its paces. No matter how good we are at controlling variables in our testing, one variable we can't
