The F1 Tech Behind Modern Time Attack Aero

Aerodynamics plays a huge role in modern time attack cars, but developing an effective package is far more complex than simply bolting on a larger wing. We caught up with Kyle from JKF Aero to discuss how aerodynamic development actually works within the constraints of the World Time Attack Pro Open rule set, and how teams interpret those rules to design competitive aero packages. 🏎️ Building a fast car?

Designs are then tested in CFD before moving into manufacturing. The discussion also covers the balance between downforce and drag, why the underfloor can often contribute more downforce than a rear wing, and the challenges created by Pro Open regulations that require the centre of the car’s floor to remain open between the chassis rails. We also look at how pressure taps are used to measure aerodynamic performance directly on the car, helping correlate real-world data with CFD predictions and validate whether the aerodynamic package is behaving as expected on track. Finally, Kyle explains how the process moves from digital design to physical parts, using 3D scanning, CAD modelling, and composite manufacturing to turn aerodynamic concepts into real components that fit precisely on the car. ________________ TIMESTAMPS 0:00 - How WTAC Aero Rules Limit Wing Placement 0:19 - Introducing JKF Aero And The Evo Development Project 1:10 - How Aerodynamic Development Begins 1:25 - Interpreting The WTAC Pro Open Rule Book 2:26 - Rear Wing Height And Position Trade-Offs 3:04 - Is Front Downforce Harder To Generate? 3:25 - Why The Floor Produces Most Of The Downforce 4:12 - Balancing Rear Wing Size With Floor Efficiency 4:28 - Downforce Vs Drag Trade-Offs 5:16 - Why The Pro Open Rules Require An Open Floor 5:59 - Why Controlling Airflow Under The Car Is Difficult 6:23 - How Much Downforce A Flat Floor Could Add 7:10 - Mid-Corner Downforce Challenges 7:22 - Ride Height Sensitivity And Aero Setup 8:12 - Peaky Vs Forgiving Aero Packages 8:38 - Why Driver Skill Influences Aero Setup Choices 9:01 - Using Pressure Taps To Measure Aero Performance 10:34 - Comparing CFD Simulation To Real Track Data 11:56 - Why Absolute CFD Accuracy Matters Less Than Trends 12:08 - From CFD Design To Carbon Fibre Parts 13:33 - How JKF Aero Develops Custom Packages -------------------- FREE STUFF 🏆 Free Race Car Parts On Us | Enter the Giveaway https://hpcdmy.co/giveaway 🏎 Start Tuning With Confidence | EFI Fuel & Ignition Basics Lesson https://hpcdmy.co/EFI101y 💻 How to Tune Stock ECUs Safely | HP Tuners Fuel & Ignition Lesson https://hpcdmy.co/hptly ⚡ Motorsport-Grade Wiring Made Simple | Learn Essential Skills https://hpcdmy.co/wiringlessonyt 🧑‍💻 Design.
