Flame-Resistant Clothing for High-Performance Driving Days (HPDE)​

---

As I prepare for high-performance driving days, safety is paramount.​

I've had a Manthey roll bar installed, Sabelt racing seats, Schroth seatbelts, completed an oil change, installed new brake fluid, and conducted a full suspension review. Of course, my helmet is up to current safety standards, but I’m not ready to invest in a full racing suit. That said, I do want to protect myself as much as possible, and I’ve been looking into performance clothing that can keep me safe during a thermal event (fancy word for fire).
This led me down the path of searching for flame-resistant apparel, specifically pants, shirts, and shoes. My goal was to find clothing that not only meets industry standards for fire protection but also performs well in other areas such as comfort...

Conclusion:​

Choosing the right exhaust material for high-performance vehicles like the Porsche GT3 RS requires balancing factors like weight, heat resistance, durability, and cost. Below is a summary of key materials:

• Titanium (Grade 5 Ti 6Al-4V): Excellent for weight reduction and corrosion resistance, but comes with a higher cost and potential brittleness under impact.
• Stainless Steel 321SS: Offers superior heat resistance and durability, making it ideal for high-temperature environments, but is heavier than titanium.
• Stainless Steel 304SS: An affordable and corrosion-resistant material, but lacks the heat tolerance and weight-saving benefits of 321SS and titanium.
• Inconel 625: Offers exceptional heat resistance and durability, making it ideal for extreme conditions, though it is heavy and expensive.

As I begin to refamiliarize myself with open-source CFD software such as OpenFOAM for CFD simulation and ParaView for post-processing, I’m reminded of the steep learning curve these tools present. In previous articles, I’ve written about OpenFOAM and its powerful capabilities, and now I want to shift focus to ParaView—a powerful yet complex tool for visualizing simulation results. For beginners, the learning curve with ParaView can be just as daunting as with OpenFOAM. With so much information available, it can be overwhelming to quickly grasp the essentials required to generate simple visuals from your simulation results.

In my opinion, ParaView is one of the best, if not the only tool, for post-processing and visualizing OpenFOAM simulations. Its powerful features and flexibility make it an essential tool for anyone working with...

Conclusions:​

• For Best Lap Time (Dry Conditions):
  • Michelin Pilot Sport Cup 2 R is the top choice followed by the Goodyear Eagle F1 SuperSport RS.
• For Control & Fun:
  • The Pirelli P Zero Trofeo R.
• Wet Conditions:
  • Pirelli is the better choice however be aware of the rear-end aquaplaning.
• OE vs. Aftermarket:
  • OE tires (Michelin and Goodyear) are designed for predictability and safe handling, making them ideal for track-day enthusiasts who value stability. Aftermarket tires (Pirelli) provide higher performance in the wet, and provide consistent dry lap performance.

This is a must-watch video if you're trying to figure out the best tire for your next track day, based on your goals. The comparison covers dry lap times, with the Michelin Pilot Sport Cup 2 averaging 64.9 seconds and the Cup 2 R coming in at 64.0 seconds. Here's a breakdown of the lap times:



These times were recorded at the Michelin Tire Test Track in France, giving you an accurate representation of each tire’s performance in optimal conditions

Tire Shine Products: How They Work, Prevent Slinging & AMMO Mud Tire Gel Review​

Key Takeaways:​

• Tire shine products enhance tire appearance with a glossy or matte finish while offering UV protection and preventing cracking.
• Benefits: They improve aesthetics, protect against sun damage, and keep tires cleaner for longer.
• Downsides: Over-application or improper use can lead to slinging (product flung off the tire onto the car’s sidewalls).
• Slinging Causes: Slinging happens when centrifugal force displaces excess product, especially with thinner, more fluid formulas.
• AMMO Mud Tire Gel Slinging Analysis: The product's formula has a moderate risk of slinging, but proper application significantly reduces this risk.

Quick Takeaways​

• Airshaper is a cloud-based OpenFOAM solver that simplifies the setup and execution of CFD (Computational Fluid Dynamics) simulations for vehicle aerodynamics.
• In just under 10 minutes, you can set up your simulation by uploading a CAD model, defining boundary conditions, and choosing your simulation type.
• For a basic simulation of a vehicle (like a 991.1 GT3 RS), the cost is around €50 ($52 USD), with a simulation runtime of under 20 minutes.
• The basic simulation offers key outputs such as surface pressure, friction, aerodynamics noise (aeroacoustics), and wake structures, but is limited by a mesh of 1 million cells.
• Upgraded simulation packages with rotating wheels and higher-resolution meshes (up to 100 million cells) are available at higher costs, starting at €500 ($520 USD) and going up to €2500 ($2600 USD)...

Takeaways​

Deionized Water is Crucial​

Deionized (DI) water ensures a spotless finish by removing mineral ions that cause water spots and streaks. It is essential for achieving a clean, streak-free result after washing and drying your vehicle.

Discussed Deionizer Systems​

• CR Spotless DIC-20: High-output system providing up to 300 gallons of purified water, perfect for small to medium-sized car washes.
• On The Go Dual Bed Double Standard Deionizer: Features a dual-tank system for greater efficiency, producing up to twice as much purified water as single-tank systems.
