    158: No Compromise? Why the 8HP Might Be the Ultimate Transmission

    Having a silky-smooth automatic alongside a quick-shifting manual transmission capable of handling 1000HP in the same transmission seems impossible—but the ZF 8HP might just achieve it. Andrew Astley from 8speed joins us to explain why this transmission has become such a popular choice. 👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvip In this episode of Tuned In, Andrew shares his journey from growing up near Silverstone in the UK to becoming a leader in Australia’s aftermarket scene, specialising in 8HP conversions. He covers his early car projects, his transition from car detailing to running a wrecking yard, and the growth of his YouTube channel, Zero to 60. We dive into modern transmission technology, comparing DCTs and the 8HP, and breaking down what makes them work—and where they fall short—in high-performance applications. Andrew unpacks what it really takes to run an 8HP in a custom build, covering compatibility, installation challenges, control strategies, torque modelling, and even the use of clutch pedals or clutch emulators for applications such as drifting. We also explore how the 8HP performs across drag, drift, circuit, and street use, along with the importance of proper tuning and getting the most out of the TurboLamik TCU. At its core, Andrew’s mission is simple: to make high-performance modified cars drive like OEM. And with the 8HP, that goal is closer than ever—whether you’re building for the street or the track. 👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvip Follow Andrew here: Youtube: ZeroTo60Tube WWW: 8speed.au Timestamps: 0:00 No Compromise?

    157: Inside IndyCar’s Golden Era of Racing

    The 1990s were arguably the ‘Golden Era’ of motorsport, particularly in the world of wings-and-slicks racing. High-revving engines, intense competition, and iconic car designs made it an unforgettable time. Championship Auto Racing Teams (CART) was no exception, and Russell Cameron from Horizon Motorsport was right in the thick of it. 👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvip In this episode of Tuned In, Russell shares his journey from a small-town upbringing in South Dakota to building a successful career in the professional racing world. He discusses the evolution of his mechanical skills and his rapid transition into professional racing within the CART series. Russell also dives into the legendary Cosworth engines of the ’90s, the role of qualifying engines, and the relentless push to squeeze out every last bit of performance. From reliability to driver preferences and the subtle setup details that can make or break a lap time, he shares insights from inside the garage. We also explore his career across multiple teams, the infamous CART–IRL split, the influence of the Indy 500, and the factors that led to CART’s decline. Russell reflects on moving from team manager to team owner and the realities of running a racing team. He also talks about the incredible ‘Hammerhead’ project he built with his son, Cavan — a stunning machine incorporating a lot of ex-CART/IndyCar components. Russell has lived an extraordinary life in professional motorsport, and now he’s on a new adventure building the Hammerhead with his son. Combined with his storytelling ability, it makes this episode a seriously compelling listen. 👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvip Follow Russel here: Instagram: horizon_motorsports_llc Youtube: horizon_motorsports_llc For more on Hammerhead & Cavan Cameron listen to episode 153: A High School Project Gone Wild: 1,450HP IndyCar x Firebird.
