• Field Report: Is a 940kg Toyota MRS the ULTIMATE Grassroots Racer?

  "The closest we've got to a mechanic is a panel beater." - Has this group of friends on a budget built something quicker and more special than many big chequebook builds ever will be?Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvipMost people overlook the third-gen Toyota MR2 (MR-S), but Justin from Close Enough Racing has spent years turning his into a proper grassroots weapon.From a modest 1ZZ track car to a 450kW turbocharged 2ZZ build with APR widebody aero, a Jubu Racing close-ratio gearbox, and Porsche brakes, this is a fully developed MRS that competes on the world stage at World Time Attack Challenge.You’ll learn how Justin and his mates handled the powertrain setup, aero evolution, and suspension development while working around the MR chassis’ limitations and strengths.The car features a Gen 2 Garrett G35-82R turbo, factory-based poly bushed mounts, and a 3582R-based turbo system pushing 35 psi through a built 2ZZ engine. The team worked with brands like CMS Performance for tuning, APR for aero, Shockworks for suspension development, and even adapted Porsche Boxster calipers using custom dogbones.Despite not being professional engineers, this group of friends put together a car that can compete with far more expensive, professionally built competition.If you’re building your own track car and want to see how to combine smart part selection, testing, and a bit of ingenuity to go fast on a budget, this one’s worth your time.#highperformanceacademy #buildtunedrive  #closeenoughracing #aprperformance #shockworks #cmsperformance #juburacing #toyotamrs #mr2build #worldtimeattack #2zzge #grassrootsracing #aprperformance #cerbuild #wtac #carmods #motorsport

• 141: This Could Make or Break Your New Harness.

  Forget the hype around “Mil-Spec” wiring — most builds don’t need it. Smart, fit-for-purpose materials and design can still deliver a reliable harness with great performance and aesthetics. This week on the podcast we sit down with Technica Racewire co-founders Philip Chiu and Kevin Tan to uncover the wiring harness essentials.👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvipPhilip and Kevin share their journeys from a childhood passion for cars to becoming the owners of Technica Racewire. They discuss the transition from mechanical engineering to automotive wiring.We cover their focus on classic Porsche builds and the production run harnesses they build, the ECU brands they trust, and how they approach configuration depending on the application.They dive into the intricacies of working with autosport connectors and what are some suitable alternatives at a lower price point but still perform to a race grade level. We also cover the differences between a club level harness and a high end motorsport harness.Most importantly, they shine a light on the steps that can make or break a harness and the common mistakes beginners make when trying to DIY their first one.Follow Technica Racewire here:Instagram: @technicaracewireFacebook: Technica RacewireWWW: technicaracewire.com👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvipLinks:Autosport Manual Timestamps:0:00 This Could Make or Break Your New Harness4:12 How did you get interested in the automotive scene?

• Field Report: A BETTER conversion option?

  Ever wondered what it takes to convert an old car into a modern 600hp EV using aftermarket tech instead of a Tesla swap?Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvipAt SEMA, Rory Baldrey from Legacy EV walks through the full electric conversion of HP Tuners classic air-cooled 1984 Porsche 911 Carrera, powered by a Cascadia Motion motor and controlled via HP Tuners' Core EV VCU (ECU). Rory explains how this setup compares to more common OEM-based swaps, like Tesla drivetrains, and why they opted for a high-voltage 800V system. From regen tuning to thermal management, and the cost vs. flexibility tradeoffs of aftermarket parts, it’s a practical look into how EV swaps are evolving and what's possible at the cutting edge of performance electric conversions.#highperformanceacademy #buildtunedrive #evswap #ElectricPorsche #CascadiaMotion #hptuners #sema ‪@cascadiamotion‬ ‪@HPTuners‬

• Field Report: 550hp Micra | 'Let TORQUE take the wheel'

  Ever seen a 550whp front-wheel-drive Micra out on track?Sean Austin’s FWD K11 Nissan Micra is running a turbocharged Primera P11 SR20VE+T Neo VVL (the best SR20?) & 6-speed gearbox, Haltech Nexus R3 engine/power distribution management, Haltech iC-7 dash, and enough power to torque steer into another dimension.Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvipWith help from CDI Motorsport, Raceworks, Knight Family Motorsport, and a front end swapped in from a Pulsar, this car has evolved from track beater to full track weapon at the World Time Attack Challenge. It’s light, fast, and rowdy, but Sean’s also realistic about its limitations, admitting the platform might have hit its ceiling. That said, not sure we believe that a project is ever truely 'finished'!This walkaround covers the build, from the engine setup and fabrication, through to suspension compromises and alignment headaches. It's a quick look at what it takes to extract big performance from an unlikely chassis, and believe it or not at this stage all for under $20,000 Kangaroo Dollars (AUD).#highperformanceacademy #BuildTuneDrive #laterk11 #noideaclub #SR20VVL #Micra #FWD #k11 #TimeAttack #Haltech #WTAC2 #learndriveoptimise #learntotune #enginebuilding101 #dontletthesmokeout #wiring101 #cars #motorsport #racing #boost

• 140: You Don't Need a PhD to Add SERIOUS Performance.

  You can go a long way with club-level aero — and this is how to do it.On this week's episode of Tuned In, ex-Mercedes F1 aerodynamicist and brand new HPA tutor Kyle Forster helps you find big gains in performance by adding aero.👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvipKyle shares his journey of how he became an aerospace engineer with a passion for motorsports, he also discusses the challenges he faced while pursuing a PhD to break into Formula 1. We get a first hand look at Kyle's time at Mercedes F1 and the complexities of aerodynamics in high level racing, including the differences between CFD and wind tunnel testing and the challenges of validating aerodynamic performance in real-world conditions. Kyle digs into club level aero packages showing us you don’t need a big budget or an engineering degree to gain performance and lap time. He now runs a consulting company ‘JKF Aero’ which can help you do exactly that.We discuss the fundamental aerodynamic principles, the importance of selecting the right components, and practical methods for validating aerodynamic effectiveness that anyone can do.Check out Kyle here:YouTube: Kyle.EngineersInstagram: kyleengineersWWW: jfkaero.com👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: hpcdmy.co/podvipTimestamps:0:00 You Don't Need a PhD to Add SERIOUS Performance3:47 How did you form an interest in cars?7:40 Why was there an era where Formula SAE didn’t have aero?12:45 How did your passion for aero grow from the Formula SAE team?15:57 What is a degree, masters and PHD in Engineering?19:21 How hard was it to land a job in F1?22:06 What responsibilities do they give you when you join a team as a fresh aerodynamicist?27:43 How do you end up with a cohesive aero package where all the parts work together?31:27 What’s the process of testing these aero parts you design?37:50 Why isn’t what you see in the wind tunnel not the same on the track?48:23 What data and sensors do you have to validate aero on the track?54:26 Why don’t we use a 1:1 model in the wind tunnel?1:02:42 Why are there caps on CFD time?1:05:06 How much does ride height affect downforce? 1:06:44 How long were you in F1 and how did you exit?1:09:36 What does a typical consulting job look like for a high level motorsport team?1:11:03 And what does that look like for a club level car?1:14:13 Getting people to see the real benefit in aero?1:18:19 What does a club level guy need to know?1:24:56 How does a front splitter create downforce?1:28:38 Do we need to think about spring rates when adding club level aero?1:29:46 How do we even need our front splitter tunnels?1:32:31 How do we validate our aero components are working at the club level?1:41:19 Why is flow-vis not a viable technique at club level?1:44:55 Final 3 questions
