Triple-Turbo 12-Valve Cummins Engine
Resurrecting an old Dodge truck that had rolled down a mountain, Mike Martin’s “Franken Truck” has undergone quite the transformation. The build features a triple-turbo 12-valve Cummins engine, and it’s only the beginning of Martin’s plans for the build. Check it out!
Valve Springs
High-frequency fatigue, also known as harmonics, are a ubiquitous challenge in racing engines and can potentially wreak havoc on the valvetrain if left unchecked. Well-designed valve springs play a pivotal role in managing this, ensuring essential stability, and minimizing wear on valvetrain components.
What to Consider When Selecting Pushrods
Determining the correct pushrod length is often regarded as one of the most intricate aspects of the selection process due to the variability in valvetrain geometry and design.
Turbocharged 5.9L 12-Valve Cummins Engine
Logan Yelton’s ’93 Dodge has gone through quite the transformation. It was once used to transport him and his wife to prom back in the day to now burning rubber on the drag strip with 1,800 horsepower on command. This 5.9L 12-valve Cummins-powered monster has done it all. See what went into the build!
393 cid Billet Cummins Engine
When it comes to power, the engine propelling Scheid Diesel’s drag car doesn’t dissapoint. It makes 2,800 horsepower on fuel alone… no wonder it’s a record setter!
Turbocharged LML Durmax Dragster
Everybody loves a good diesel dragster! Paul Vasko’s is an LML Duramax, complete with a GT55 turbo, a heap of nitrous, and a number of other additions that make this build an absolute powerhouse.
Twin-Turbocharged 12-Valve Cummins Engine
Life-sized Hot Wheels? Say less. Sean Smith and his wife built this rat rod from scratch and it was a contender in last year’s Hot Wheels Legends Tour. But it’s not only for show – thanks to a twin-turbo’d 12-valve Cummins under the hood, this ride makes quite a bit of power too!
Triple-Turbo 6.7L Powerstroke Engine
Is there anything better than a diesel dragster? Yes. One with three big S480s mounted on it. This Powerstroke was built by Dan Snyder of SPE Motorsport and we got the scoop on it at this year’s Ultimate Callout Challenge.
L5P Duramax Engine Swap
There’s not a ton of performance aftermarket additions on this build, but Keith Porter’s ’52 Chevy 3100 is unique for the fact it has a swapped-in L5P Duramax, one of very few to do so paired with a 10-speed Allison transmission.
Turbocharged and Nitrous-Powered 6.0L Powerstroke Engine
At this year’s Ultimate Callout Challenge, we ran into more folks just starting to get into racing their diesels than we have in the past. One such racer was Connor Wagner of Wagner Diesel Solutions. His shop specializes in the Powerstroke platform, so he decided it was time to start showcasing what he can do
Turbocharged 6.0L Powerstroke Engine
You can always count on Warren Diesel Injection to pull up to events in a sweet Powerstroke truck – they’ve been innovating the platform for over a decade. We saw this 6.0L at the 2023 Ultimate Callout Challenge and this thing is next level awesome.
Turbocharged 7.3L Powerstroke Engine
Every year, there’s hundreds of diesel trucks at the Ultimate Callout Challenge. As expected, most feature 6.7L Cummins engines, but that’s what makes seeing a Powerstroke build that much more special – let alone a 7.3L. We were able to find one built and owned by Corey Hurtts of CNC Fabrication. Check it out!
