Revisited: Want to Get Your Car Handling Better Than Ever Before? Listen to This.

*** We’ll be taking a break over the Christmas/New Year period and will be back in action mid-January. That means that although there won’t be any new episodes for a few weeks, we’ll be taking another look back at some of our favourite episodes. *** Are you sick of playing the guessing game when it comes to setting up the suspension and tyre systems in your race or road car? If you’ve ever felt like you’re throwing alignment adjustments, damper settings, and spring rate changes at the pit wall just to see what sticks when making changes to your or your customer’s vehicle, then this episode with Bruno Finco of Optimum G is going to be a perfect listen. 👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvip Originally from Brazil and now based in Colorado, unusually for a guest of the Tuned In podcast, Bruno didn’t have all that much interest in cars growing up — it wasn’t until he went to university to gain a degree in mechatronics engineering that he joined the school’s Formula SAE team and began a life-long love affair with all things motorsport. Walking out of university and straight into a role at Colorado-based Optimum G, Bruno has since gone on to become the motorsport tech company’s Lead Performance Engineer, and now spends his time travelling around the world’s greatest race circuits, gathering data, helping both race teams and OEMs optimise their vehicle dynamics, and teaching others how to do the same through the use of Optimum G’s highly-regarded software packages. The bulk of this admittedly very tech-heavy episode consists of Bruno talking us through the many nuanced points of motorsport handling and performance, breaking down concepts into their many facets. This includes roll centre, tyre slip angle, Ackermann steering, anti-dive and squat, plus much more. Bruno also explains how Optimum G’s software works, and most interestingly, despite how it first looks, how it’s not something you need to have a Ph.D. in order to understand and use to substantially improve your vehicle’s performance. 👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvip A more thorough explanation of Ackermann steering can be found here.

Revisited: Is Honda’s K-Series Really the Greatest 4-Cylinder Ever Made?

*** We’ll be taking a break over the Christmas/New Year period and will be back in action mid-January. That means that although there won’t be any new episodes for a few weeks, we’ll be taking another look back at some of our favourite episodes. *** Few people know more about ultra-high-performance engine building than this week’s guest, Terry Radbourne of Bourne HPP. In this episode, we’re going to be discussing topics like creating engines for LMP1 and Mercedes’ F1 team, truly getting the absolute most out of Honda’s K series motor, as well as the odd controversial opinion that’s sure to get the comment section fired up. 👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvip Terry brings an intriguing mix of expertise and insider knowledge — straight out of school, he found himself working for Advanced Engine Research and quickly became involved in some seriously high-end race engine design and building work. After a few years spent honing his craft — including a stint creating engines for the Mercedes Formula 1 team, Terry went on to found his own company, Bourne High Performance Powertrains, or Bourne HPP for short. Bourne HPP specialises in designing and building seriously aggressive motors — most commonly of the Honda K-series variety in both naturally aspirated and turbocharged forms. This allows us to dive very deep into the intricacies of four-cylinder engine building, and time is spent discussing intake port design, cylinder sleeves, compression ratio, and a whole lot more. We also get stuck into the K-series motor itself, and Terry spends time talking us through exactly why he thinks this is one of the best engines ever produced and how to get the most out of it. As Bourne HPP is something of a one-stop-shop that does everything from engine rebuilds, to NA and turbocharged crate engine packages, to dyno tuning with the use of Syvecs and Lyfe Racing ECUs, Terry has an absolute oversupply of knowledge that he’s (mostly) willing to share. If you want to get smarter, this episode with Terry Radbourne of Bourne HPP is not to be missed. 👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvip As mentioned in the podcast, you can listen to our episode featuring Syvec’s Ryan Griffiths here: https://hpcdmy.co/Syvecs Follow Bourne HPP here: IG: @bourne_hpp FB: Bourne HPP WWW: bournehpp.com
