158: No Compromise? Why the 8HP Might Be the Ultimate Transmission
Wednesday, 25 March, 2026
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/podvipIn 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/podvipFollow Andrew here:Youtube: ZeroTo60TubeWWW: 8speed.auTimestamps:0:00 No Compromise?
