From low weight and tight packaging to innovative techs like portal hubs and rear-steer functionality, this 10mph max speed and 42" BF Goodrich tyre-equipped buggy is a masterclass in off-road engineering. During SEMA, Rodney takes us through the key decisions, such as using a 220hp 2.0L Chevy LNF Ecotec engine for its compact size and power-to-weight ratio and the ingenious placement of the axle-mounted fuel cell for improved safety and balance.

Learn how air lockers and diff locks provide precise control, and how hydraulic winches keep the suspension loaded during vertical climbs. Plus, explore the air suspension system that allows the vehicle to adjust ride height by up to 20 inches on the fly.

On the electronics side, Rodney explains how the Ecumaster PMU16 and ADU5 Dash streamline power distribution and steering control using Blink Marine CAN-based keypads. With clever innovations like adjustable steering indicators and a ride height potentiometer, this buggy has no shortage of cutting-edge solutions.

If you’re into off-road motorsport or just love clever engineering, this deep dive into rock-crawling tech is one you won’t want to miss.

Considering striking out on your own in the performance automotive industry? There’s nothing more satisfying than building your own successful business and being your own boss but… getting it right isn’t easy.

On this episode of Tuned In, we catch up with M26 Engineering’s Matthew Bernasconi, who we first interviewed back in 2022 just as he was leaving stable employment at offroad legends Kibbetech to build his own business.

At the ‪@toyotires‬ booth during ‪@semashow‬ Cam gives us some insight into his welding progression and working process without the use of CAD, with that being a skill he wishes to learn during future projects. The CSF triple pass radiator is rear mounted to aid with weight distribution, and interestingly, this model of E30 came with rear ballast from the BMW factory. The Radium Engineering fuel system behind the Ford 8.8 rear diff also helps to get weight over the rear and a 48/52 split.

The Redux Racing ITB-equipped 7L LS-based engine is controlled by a suite of Haltech electronics, and a Live To Offend kit is fitted to the E30 care of SOS Customs handiwork. We didn't get a rundown on the full brake package, but a Wilwood pedal box is equipped which will serve Cam well if he decides to hit the track for some time attack racing in the future.

*** We’ll be taking a break over the Christmas/New Year period and will be back in action mid-January.

If you’ve spent any time on YouTube, you’re probably already aware of this episode’s guest and the various projects his channel is involved in — most famously “Project Binky”, a classic Mini running a Toyota Celica GT-Four engine and AWD driveline.

Richard Brunning from Bad Obsession Motorsport joins us to down a few cups of tea, talk motorsport, and run through the ins and outs of neverending project cars, the business of operating a popular automotive YouTube channel, and much more.

Richard, like many guests of this podcast, has his father to blame for his motorsport obsession. Some of his earliest memories involve hanging out in old sheds while his Dad restored vintage vehicles, tickling up RC cars to get the edge in racing, and days spent on the couch watching Formula 1.

This early focus on all things automotive drove Richard towards a life that revolved around motorsport, first starting out in kart racing, before moving on to Caterhams, formula cars, and even some Formula Mazda racing in the States. In this episode, Richard spends time talking us through these different forms of motorsport, and discusses how each type of vehicle could be set up, tweaked, and modified within the rules in order to gain more speed.

Eventually, Richard’s good friend and eventual partner in crime, Nik Blackhurst, enticed Richard back to the UK to help him go rallying, and it was at this point, way back in 1992, that Bad Obsession Motorsport began.

Fast forward a good few years, and Richard and Nick were fed up with the car modification TV shows like Pimp My Ride, Monster Garage, and their contemporaries that were on offer at the time — none of them actually showed why and how any of the work was done. This got the pair thinking that they might be able to do better, and with that goal in mind, the Bad Obsession Motorsport YouTube channel was founded.

It took a couple of years, but Richard and Nick’s channel began picking up steam, not in small part thanks to “Project Binky”, a Toyota Celica GT-4 powered and driven classic Mini. Richard dives deep into this build, answering our burning questions — chiefly ‘Why’? But also “What’s taking so long”?

This in-depth discussion around the challenges of fitting so much engine and driveline into such a small package is a great look into what it takes to complete a complicated project to a high standard. Lastly, we also spare some time time to touch on the joys of motorsport wiring, ultra-budget racing in the City Car Cup, and making a living out of building cars on YouTube.

Turbosmart is well known for many quality performance accessories including wastegates, blow-off valves, fuel pressure regulators, anti-lag valves, boost controllers and more, but until recently they stopped short of selling turbochargers themselves.

Use ‘PODCAST75’ for $75 off your first HPA course here: https://hpcdmy.co/hpa-tuned-in

At the World Time Attack Challenge, Matt Wright gives us some insight into how Turbosmart decided to not only sell turbochargers but to sell their own designed in house with help from industry experts like Harry Hruska to get the ball rolling. There's no two ways about it, this move simply makes sense for a company like Turbosmart to explore.

Unlike how design was done by the pioneers of aftermarket turbocharging years ago using a lot of prototyping, these days Matt explains how the use of computer-aided design (CAD) software and computational fluid dynamics (CFD) means a lot more theories can be discussed and tested before physical prototypes are made, giving Turbosmart the chance to explore a lot of design elements that traditionally would simply be too expensive to entertain.

Also touched on are some of the material and manufacturing considerations, turbo selection and how leveraging industry experience helps decide what target markets want a wider range of turbocharging options/solutions.

In this pit lane interview, Sean from Ramsdell Racing will explore the advanced EMtron ECU technology behind the Dream Project S15 at the World Time Attack Challenge. Sean breaks down how the EMtron ECU is one option using traditional OEM tuning strategies to transform power management in high-performance applications, making it possible to deliver more and more horsepower effectively through the tyres and onto the race track.

With Emtron’s sophisticated tractive force calculation, Sean explains how the ECU is optimizing torque delivery based on real-time data from tyre diameter, diff ratios, gearbox ratios, and more. This technology ensures the S15 can push the limits while maintaining traction in every gear, ultimately translating to faster lap times and a smoother driving experience.

A major innovation highlighted in this interview is throttle mass flow modelling, which lets torque be precisely mapped to the driver’s foot pedal. This linear relationship offers drivers enhanced control, enabling quick adjustments without sacrificing power. This level of control, traditionally seen only in OEM systems, is now at the forefront of the aftermarket scene with Emtron’s developments.

Anyone with even a passing interest in Time Attack has likely heard of Norris Designs, a UK-based tuning company probably best known for its insane north-south oriented, twin-charged, short-wheel base Evo IX time attack monster. On this episode of Tuned In, we sit down with founder Simon Norris to get some insight into this brain-melting build, plus much, much more.

Like many of us, Simon Norris began his love affair with cars and motors early in life, pulling apart engines on the kitchen table as a child. While there was a slight detour after leaving school to study engineering, it wasn’t long before Simon spied a new opportunity in the burgeoning JDM aftermarket tuning scene just as he was cutting his teeth working in a Nissan dealership in the mid-nineties. So, after seeing how others were starting to mess with tuning ECUs, Simon decided he could do better, and promptly opened Norris Designs way back in 1998.

Nearly three decades later, Norris Designs is one of the biggest names in the UK tuning scene. In this conversation, we first kick into the business side of Simon’s life, finding some great insight into what works and what doesn’t when it comes to building a company in the motorsport industry. 

We next get into tuning in general, where Simon discusses different ECU options, dyno styles, and the many factors that can cause discrepancies between individual dyno runs. From there it’s on to the real meat and potatoes of this episode — Simon’s incredible Mitsubishi Evo IX. 

With its north-south-orientated billet supercharged AND turbocharged 4G63, the AWD Evo is an engineering masterpiece that absolutely tears up any race circuit it’s unleashed upon. Simon does his best to answer the many questions we have about this car in an attempt to get to the bottom of what makes this shortened and roof-chopped weapon tick, and why Simon made the choices he has with this build.

In this interview, we sit down with Charles from Lamspeed to explore what it takes to turn Toyota’s GR Yaris into a record-breaking machine, using a surprising amount of standard parts! The team currently holds the title for the world’s fastest GR Yaris, with a 9.6-second quarter-mile at 155 mph at the time of filming and a 9.4-second pass since then, resetting their own record. Charles dives into the challenges and engineering breakthroughs Lamspeed encountered along the way.

To push the Toyota Yaris G16E-GTS 1.6-litre, three-cylinder engine to extreme levels (pushing almost 900hp out of a 3-banger is impressive!), Lamspeed relies on key components from top brands, including MoTeC for advanced engine management, handled by Phil from Armour Motorsport, and Carrillo CP for custom pistons and rods to support the high-power demands. 

For turbocharging, Lamspeed initially used a Garrett G30-770 for circuit racing and has since continued refining setups to extract maximum performance with a Kelford Cams valve train aiding in great turbo response along with the retained variable valve control system. A ported head and supporting mods added around 180hp along with head studs custom-produced by ARP to address head-sealing issues early in development, a critical factor for reliability under high boost.

Transmission upgrades include a Kotouč 7-speed sequential gearbox for drag racing reliability and previously tested options from Drenth. With Lamspeed’s detailed and iterative approach, every part and upgrade has been meticulously selected and tested to push the limits of the GR Yaris platform without compromising performance.

Ever wondered if a wheel’s stiffness can affect camber or how rotational inertia plays into vehicle response? Eddie from Titan 7 explains their commitment to minimizing deflection, reducing tyre creep, and designing spokes that strike the perfect harmony between strength and aesthetics.
