In this episode of Tuned In, we dive into Nate’s background, from growing up in a machine shop and studying optical engineering to designing advanced laser systems for autonomous vehicles and military applications. Along the way, he developed a passion for mechanical design and engineering, eventually turning the off-road vehicle concepts he’d been imagining since childhood into detailed CAD creations shared with a growing online audience.

We then explore the tools and processes behind Nate’s designs, covering everything from SolidWorks and finite element analysis to CNC machining and additive manufacturing. The discussion highlights the importance of designing for manufacturability and understanding engineering fundamentals before they ever reach the real world.

The conversation also dives deep into off-road vehicle design, from suspension geometry and wheel travel to weight optimisation and structural analysis. Nate explains how he balances performance, durability, and practicality while constantly pushing the limits of what’s possible in his designs.

This episode is packed with insight for anyone interested in CAD, engineering, fabrication, or vehicle design. Whether you're creating parts for your own project car or simply fascinated by the process of turning ideas into reality, Nate’s unique perspective makes this a fascinating listen.

Automatic transmissions were once the last thing performance enthusiasts wanted in their builds—but that’s changing fast. Greg from Turbolamik is at the centre of that shift, helping bring ZF’s 8HP gearbox into everything from drift cars to drag builds, and showing just how capable modern automatics have become.

In this episode of Tuned In, we dive into Greg’s background, from growing up around grassroots motorsport in Poland to building a life in the US surrounded by rally and performance cars. His early experiences with Subaru’s and rally culture set the foundation for a career spent building cars, working with teams, and staying closely connected to the evolution of performance technology.

The focus then shifts to the ZF 8HP gearbox and why it’s quickly become such a popular swap. We break down its efficiency, strength, and fast shift speeds, along with how it compares to manuals, traditional automatics, and sequential gearboxes. Greg explains why these transmissions can handle serious power and how they’re being used across different motorsport disciplines.

We then dive into the Turbolamik standalone controller and what’s involved in making these swaps work. From CAN integration and torque modelling to adaptive shift strategies and advanced features like transbrake and launch control, the discussion highlights how full standalone control unlocks the true potential of the 8HP platform.

This episode is packed with insight into one of the fastest-growing trends in performance cars. Whether you’re building a drag car, drift car, or street machine, understanding the potential of modern transmissions like the 8HP could completely change how you approach your next project.

In this episode of Tuned In, we dive into Jake’s background and how a family history steeped in motorsport set the foundation for his career. From building cars in his teens to running his own shop and developing race engines, Jake shares how a mix of curiosity, study, and real-world experience shaped his approach to engine building.

We cover the fundamentals that underpin everything Jake does—covering topics like harmonic dampening, bearing clearances, oil viscosity, and why many common engine-building “rules” aren’t as black and white as they seem.

Jake then unpacks airflow and cylinder head development, breaking down the often misunderstood relationship between flow and velocity and how factors like surface finish, valve seat design, and port shape all contribute to real-world performance. We also explore intake manifold design and the role of runner length, plenum volume, and harmonic tuning in maximising engine efficiency.

This episode is packed with practical knowledge and deep technical insight. Whether you’re building engines, tuning them, or just want to better understand how they really work, Jake’s ability to connect theory with real-world results makes this one a must-listen.
