Bypassing the Norm – Thermal Bypass Valve R&D, Part 1: Design to Delivery

The transmission is the backbone of your 2013–2018 Dodge Ram 6.7L Cummins. It’s responsible for transmitting up to 930 lb-ft of torque from the engine to the wheels. That much power generates a lot of heat and if that heat isn’t dissipated, it can destroy your transmission. The transmission cooler does a decent job of keeping transmission fluid temperatures in check, but only if the fluid can reach it.

The stock cooling systems of both the 68-RFE and Aisin AS69RC utilize an in-line thermal bypass valve that controls the flow of fluid to the transmission cooler. The purpose of this valve is to … Continue Reading ››

In Good Health – Baffled Oil Catch Can Kit R&D: Start to Finish

If you’re like most 6.4L Powerstroke owners, your truck is your livelihood. It gets you around, carries your tools, tows your equipment, and anything else you need to get the job done. You rely on your 6.4L every day and want to keep it healthy, but your 6.4L isn’t as diligent about its own well-being.

Like all modern internal combustion engines, the 6.4L Powerstroke generates blow-by. This blow-by is made of carbon, oil, fuel, and water vapors that leak past the piston rings during combustion. Blow-by can be extremely detrimental to the bottom end of … Continue Reading ››

Breathing Fresh Air – Intake R&D, Part 9: Production

As Ye tightened the last bolt on our intake production sample, we breathed a sigh of relief. Over a year of painstaking R&D came to a close with that bolt.

In all our years designing intakes, few have been as complex or demanding as our 2018+ Jeep Wrangler JL 2.0L intake. We’ve fought check engine lights, tested more variations than we could have imagined, and learned a lot along the way. But the time is finally here to see the product of our efforts in its final form.

Float Like a Butterfly, Sting like a Kia? – Performance Intercooler Kit R&D, Part 5 – Piping Production Sample

Unfortunately for us, Bluetooth intercooling hasn’t been invented yet. So when it came to updating and rerouting the intercooler's end tanks, we still needed a physical channel for the charged air to pass through. Put simply, it's not just the intercooler getting the overhaul, it's the entire system. This means more work for us, but you get to reap the benefits.

Kia’s engineers already equipped the Stinger GT with one of the most robust intercooler piping systems that we’ve … Continue Reading ››

Float Like a Butterfly, Sting like a Kia? – Performance Intercooler Kit R&D, Part 4 – Intercooler Production Sample

The splash has been made, and those ripples have finally made their way to shore. The proverbial pond that is the auto industry is a big one, but it’s now time to see the end result of our big plans for the Stinger GT’s intercooler upgrade.

There are a few aspects that the Stinger came up short on when it was released into the wild, and we saw the intercooler being a weak link. Given its design, it wouldn’t be able to keep intake air temperatures at an appropriate level after some thrashing and … Continue Reading ››
