150: The Self-Taught Way: Building Wild Engines from ScratchImagine being a self-taught engineer who mastered the intricacies of engine design and is now building bespoke engines from the ground up. That’s exactly what Josh Valman from Motorsport_Engineering has done. We welcome Josh back for his second appearance on the podcast. This time, we catch up on his wild Alpha V8 Hayabusa project and dive into his latest creation — a turbocharged hot-vee V6 bespoke engine. 👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvip In this episode of Tuned In, Josh shares his journey from self-taught engineer to bespoke engine designer and builder. We check in on his progress with the Alpha project before unpacking the details of his new V6 design. We explore the technical side of engine performance — including pre-ignition chambers, variable valve timing, and the unique benefits of a V6 engine configuration. Josh also discusses the finer points of engine design and the importance of balancing stroke and bore ratios while selecting the right compression ratios for boosted engines. With deep expertise in machining and manufacturing, Josh offers valuable insights into precision machining, materials selection, heat treatment, and maintaining tight tolerances in high-performance engine parts. If you’re fascinated by engine design, engine building, machining, or CAD, this episode is packed with knowledge. Josh’s passion for sharing his experience makes it a must-listen for anyone interested in the art and science of building engines. 👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvip Follow Josh here: Instagram: Motorsport_engineering Youtube: Motorsport_engineering Timestamps: 0:00 The Self-Taught Way: Building Wild Engines from Scratch 3:34 Welcome back, Who are you?

149: Cracking the CAN Code: Mastering Integration in Performance BuildsCAN communication might seem like a secret, nerdy language spoken only by electronic components —and, in a way, it is. But behind that digital chatter lies the key to unlocking integration between different electrical systems. Mitch Minton from Minton Performance joins us to unpack CAN communication—how it really works, and why it’s become such a crucial part of the aftermarket performance world. 👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvip In this episode of Tuned In, Mitch shares his journey from a casual interest in cars, sparked by ‘The Fast and the Furious’, to becoming a skilled automotive technician and data analyst. He reflects on the evolution of his expertise and his experiences in race engineering and mobile diagnostics. We then dive into the fascinating world of CAN communication, exploring its vital role in modern automotive systems. Mitch breaks down the complexities of CAN protocol, explaining data transmission, how to decode negative values, and the purpose of his CAN gateway. We explore the challenges of integrating aftermarket ECUs and how intricate modern vehicle data networks have become. Mitch explains why continuous learning in this field is essential for anyone serious about automotive technology. With modern vehicles packed full of electronic modules, traditional engine swaps, gearbox conversions, and standalone ECU upgrades aren’t as straightforward as they once were. Without the understanding and use of CAN communication a lot of these modifications are no longer possible. 👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvip Follow Mitch here: WWW: mintonperformance.com Youtube: @mintonperformance Facebook: Mitch Minton Timestamps: 0:00 Cracking the CAN Code: Mastering Integration in Performance Builds 4:37 How did you get interested in cars? 9:11 At what point did you decide to go down the IT road? 12:45 What is your work history and where are you today? 14:54 Can you tell us which HPA courses you took and how you found them? 19:34 What sort of race engineering and data analysis did you get involved in?29:40 How easy is it to understand and use different data loggers? 34:34 Why did you stop doing data analysis? 36:16 What does your current working role look like? 38:33 What is CAN? 45:30 How do the CAN high and CAN low wires work? 47:25 Is there a limit of nodes depending on the Bus length? 48:33 What is the benefit of using CAN Bus? 54:12 What does a CAN message look like? 1:03:29 Why can’t we send the data in the numbers we want to see? 1:05:04 What hardware and software do we need to reverse engineer a CAN Bus? 1:14:10 What is a CAN gateway? 1:19:20 How do we run a modern DCT gearbox on a standalone that doesn’t accurately log torque output? 1:23:09 How do you actually control and program the CAN gateway? 1:24:55 Could you offer a standard and a pro version for different users? 1:28:21 What is CAN 2.0 and what is CAN FD? 1:31:57 Where do you place the data in addresses of importance? 1:33:43 How mainstream is CAN FD at the moment? 1:35:20 What is FlexRay? 1:37:50 Is it going to get harder and harder to make stand alone ECU’s work on late model vehicles? 1:45:08 Final 3 questions
