Old Dog, New Tricks – Intercooler R&D, Part 5: Dyno

Power feels different for everybody. For some, it’s the feel of freshly printed money. For others, power feels like the blinding camera flashes of paparazzi. But for many automotive enthusiasts, true power is the shove you feel in your back as you push your right foot to the floor. The enthusiast’s quest for power can be never ending (just ask the participants of TX2K) and Mishimoto has been working on an air-to-water intercooler for the 2011-2016 Ford 6.7L Powerstroke to aid in that journey. We’ve looked at the stock 6.7L intercooler’s faults in depth and followed the development of our … Continue Reading ››

Old Dog, New Tricks – Intercooler R&D, Part 4: Strong by Design

It wasn’t too long ago that we saw our 2011-2017 Ford Powerstroke 6.7L air-to-water intercooler on the flow bench. We talked about flow rates, and pressure drop, and learned that our intercooler flows air about 22% better than the stock cooler. Soon, we’ll see how that increased flow translates into power on the Dynapacks. But first, I wanted to circle back to our original goal for this project: make the intercooler stronger. We started this project over a year ago after finding reports of owners and shops chasing disappearing coolant. Further inspection would show that the stock intercoolers were leaking internally, … Continue Reading ››

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 … Continue Reading ››

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 … Continue Reading ››

Old Dog, New Tricks – Intercooler R&D, Post 1: A Core Review

Everything about Ford’s Super Duty Powerstroke brand screams, well, Super Duty. It has done so since they were first put in the Econoline Vans in the mid ‘90’s. Our 2011 is equipped with the 6.7L turbodiesel V8 engine, and it’s clear Ford has engineers who really took the Super Duty term to heart. There are two batteries, two radiators, two thermostats, two coolant expansion tanks, an engine oil cooler, a transmission oil cooler, an EGR cooler – this truck even has a fuel cooler. Just looking at the engine bay of this monster can be a bit daunting, especially to … Continue Reading ››
