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.
• Big Boi D-IONIZR1SET (2-Stage Filter System): A compact system with carbon and deionized resin filters, offering a TDS meter for precise...

In this upcoming article and video tutorial, I'll be installing a Manthey Roll Bar, a racing seat (either Recaro or Sabelt), and Schroth Racing harnesses in my 991.2 GT3 RS. This guide will walk you through the process, offering valuable tips for anyone looking to prep their car for the track!

After testing and tweaking my Worx 40V Power Share TURBINE Cordless Leaf Blower, I discovered how to increase its thrust by up to 21.13%—making it far more effective at removing water droplets from the surface of my car after washing. In this article, I’ll walk you through the simple modifications I made and share key insights that could help you improve your leaf blower’s performance too.

Key Insights:​

• The largest improvement came from 3D-printing a new nozzle, removing the inlet mesh and flow straightener. The 3D-printed nozzle had an exit diameter of 78.5 mm, calculated by taking 92.5% of the Fan Swept Area (FSA). This resulted in a 21.13% thrust increase.
• Simply removing the OEM plastic nozzle does not improve thrust. In fact, it actually decreases thrust by 10.57%, contrary to some claims you might find online.

Key Takeaways​

• Porsche recommends replacing magnesium wheels on the 911 GT3 RS after 10 years or 40,000 miles, whichever comes first.
• Magnesium wheels, while lightweight and strong, are more prone to material degradation, particularly from corrosion and fatigue.
• This guideline is part of Porsche's effort to maintain the safety and performance of the vehicle, ensuring that the wheels remain structurally sound even after extended use.
• While these replacement intervals are recommended by Porsche, it’s important to verify the guidelines with an official source, like your Porsche dealership or service manual.
