Some people learn engines by doing—others take it a step further and truly understand the physics behind what’s happening. Jake from Bain Racing sits firmly in that second category, combining hands-on experience with deep engineering knowledge to build some seriously impressive engines.

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.

From carburettors and distributors to neural networks and AI-driven ECUs, Gerry Bechet’s career spans the full evolution of modern engine control. From his early days at Toyota South Africa to high-level development work at Ricardo, Renault, and Holden Special Vehicles, Gerry has been right at the heart of OEM engine calibration and development.

In this episode of Tuned In, we dive into Gerry’s journey through the automotive industry, starting with his early passion for mechanics and progressing into a career as a mechanical engineer specialising in engine development and calibration. We unpack his time at Ricardo working on diesel engine R&D, including common rail injection and combustion chamber design.

The conversation then shifts to OEM calibration at HSV, where Gerry worked on GM’s LS platforms. We explore the realities behind factory tuning—balancing power, emissions, durability, and even marketing demands—and why factory ECUs are far more complex than most people realise.

We also break down the tuning myth of “magic numbers,” why airflow modelling is everything, and how small errors in injector data or fuel pressure can throw an entire calibration off. Gerry shares real-world examples that highlight why understanding the fundamentals still matters—no matter how advanced the software becomes.

Finally, we get into Gerry’s current role with HP Tuners and the development of the new Core ECU. Designed to bridge the gap between OEM-level control and aftermarket flexibility, this standalone system brings advanced strategies like MAF and speed density integration, along with AI-assisted VE tuning. We discuss where it fits in the market, who it’s for, and how tuning technology is continuing to evolve.

This episode is packed with insight—from old-school engine fundamentals to cutting-edge ECU development. Whether you’re a tuner, engineer, or just passionate about performance cars, Gerry’s depth of experience makes this one well worth your time.

We all fantasise about dream car builds, whether they’re elaborate masterpieces never done before or something stock standard we’ve seen a hundred times. Some people just have a knack for making things cool, and Ryan Tuerck from 411 Works is firmly in that category, with what might be the coolest collection of Toyota performance builds out there.

We had to get Ryan back for a second episode to unpack his latest creation—an insane ST205 Toyota Celica—and to find out more about his new business, 411 Works.

In this episode of Tuned In, we catch up with Ryan and see how things have been going in the Formula Drift world. We discuss the decision to move to a different engine combination in the search for more power, and how it hasn’t come without its challenges.

We dive into Ryan’s most recent build, his insanely cool Toyota Celica. We discuss the modernised running gear and the decision to go down in capacity from the original 2.0L 3S-GTE to Toyota’s new and popular G16E three-cylinder direct-injected engine. We also cover his anti-lag setup, ECU and electronics, plans for racing and driving the car, and how he comes up with these epic build ideas in the first place.

We then get into Ryan’s other big project at the moment, 411 Works. Through this new business, he’s begun supplying performance parts all around the world. We chat about the products they’re making and how they’re continuing to grow and develop exciting new parts.

This is another standout episode with Ryan. From a long and successful Formula Drift career to next-level builds and a growing business—if Ryan Tuerck is involved, it’s always worth a look.
