Welcome back to the Tech Heads F1 Podcast. Firstly a word of apology. This episode was recorded under an ambitious schedule with the intention of being released during the Spanish GP weekend, but was pushed back due to the extremely busy nature of the race build up and the Grand Prix itself. Nevertheless, the Tech Heads team had a fantastic conversation about the Monaco GP race weekend and the tech developments revealed by crashes, as well as covering the Indy500 and the track changes for Spain. One benefit of a late episode is knowing if our pre-race predictions were right! (hint, about Ferrari they were). Please enjoy this latest episode, and we will cover technical developments from the Spanish GP in Episode 20.

Welcome back to the Tech Heads F1 Podcast! F1 Spring Break is nearly over as we enter a stretch of five races in six weekends, starting with the always entertaining Azerbaijan GP. The week we're once again joined by F1 Tech expert Craig Scarborough, aka @ScarbsTech. If you are (somehow) unfamilar with Craig's work, he is a prolific freelance journalist/illustrator with extensive knowledge of Formula 1 technology gained over decades of experience in the sport. He can regularly be found answering technical questions on Twitter and Instagram, presenting his analysis on F1TV Tech Talk, or writing articles for Race Tech Magazine. This week we cover a range of topics including the (electric) future of wheel guns, surprise F1 Tech stories of 2023, why suspension has once again become critical in the new ground effect era, and how well teams managed the 2023 floor changes. We also discuss the evolution of Red Flag use in F1, MotoGP Tech, and Craig's most prized item from his collection of F1 memorabilia (hint: it's currently being displayed at the F1 Exhibition). This was an extremely enjoyable conversation, thanks again Scarbs for stopping by to chat!

Welcome back to another episode of the Tech Heads F1 Podcast! Bryson and Dr. Obbs officially welcome Molly Oxner as the third co-host to the show, and we we commemorate the occasion with a very special guest joining the studio for Episode 5. Few individuals in the F1 Tech space are as prolific and well-versed as our invited guest, Craig Scarborough aka Scarbs F1. Despite not formally being trained as an engineer, illustrator, or journalist Scarbs has nevertheless managed to excel at all three, becoming one of the foremost experts in the field through a long career of studying, writing, and teaching others about the wonderful world of Formula 1 technology. When not explaining complex mechanical and aerodynamic concepts through detailed threads and articles online, Craig provides technical analysis for Formula 1 on it's very popular F1TV Tech Talk program. In this week's episode, Scarbs sits down to give some insight into how F1 became his passion (along with aircraft), while we discuss in detail some key topics, including his thoughts on the 2022 season thus far, suspension tricks and compromises without gas springs or inerters, how F1 gearboxes work, and what to get excited about in 2026 and beyond. This was a great discussion, we hope you enjoy!

Episode 3 of the Tech Heads F1 Podcast dives deeper into the world of motorsport aerodynamics with a very special guest! Bryson and Dr Obbs are joined by former Audi aerodynamicist and Force India/Racing Point aero design engineer Martin Buchan, otherwise known as the legendary B-Sport. Martin is well known for his insightful YouTube videos on the aerodynamics of Formula 1, prototypes, and endurance racing cars. We discuss technical details of the differences between designing aerodynamics for road cars versus F1 cars, the 2022 aero regulations for wake control, the importance of the floor edge design, and the (many) tricks teams have employed in service of aero development during the cost cap. Martin also shares some humorous stories about real-world aero developments in F1, and creative ways in which a person can improve their chances of being noticed in the industry. We enjoyed this conversation so much, this is an episode you won't want to miss!

The Tech Heads F1 Podcast is officially here!! Join co-hosts Bryson Sullivan and Dr_Obbs as they explore all manner of technical topics from the first half of the 2022 F1 season. This inaugural episode addresses the aerodynamic intent of the 2022 technical regulations, and analyzes whether or not they have been as effective as desired. Bryson and Dr_Obbs assess how some teams could be using the floor strakes to generate big downforce, and discuss in detail how this critical area of the floor relates to the aerodynamic balance of a Formula One car. In this week's “Tech Focus” segment, we discuss the complex nature of induced drag and it's detrimental to car performance. How is this topic of induced drag linked to the new Aston Martin rear wing, and could teams copy this in the future? All this and so much more in Episode 1 of the Tech Heads F1 Podcast.
