Exploring pressure gradients on a 90-degree bend shows why mandrel bends aren't ideal for corners. Analyzing both velocity and pressure gradients is key to understanding fluid dynamics in these situations.

This is what an optimal bend in an exhaust port looks like. We're talking about a specific gradient that enhances performance, as seen in superbike designs. See the difference it makes.

Struggling with fluid dynamics? We break down why fluids are compressible and the crucial difference between laminar and turbulent flow. Understand why 'turbulent ports' aren't always what they seem and how separation impacts performance.

Sudden changes in cross-sectional area, especially sharp 90-degree bends, create immense pressure. This isn't just bad for airflow and velocity; it directly impacts engine harmonics. We're diving deeper into pressure gradients and port angles to understand their downstream effects and how port angle stabilizes the short turn.

Ever wondered why the shape of a valve stem matters? It's all about aerodynamics. A round opening creates eddies, while an oval shape, achieved by a 45-degree cut, allows for smoother airflow. This port velocity and angle approach is critical for performance.

One we did a while back!

Another Bain intake on something a little different. We also did a custom expansion tank styled to the cam cover, and set-up the electric water pump system.

Its a little pocket rocket! 💪

A go-fast Es**rt was always John Dennis’s goal, but the turbo street/track weapon he ended up with is a genre-busting masterpiece

Ever wondered how runner angle changes downstream flow and pressure? We're diving into compressible fluids, pressure gradients, and density differences. Discover how accelerating air shifts density, affecting everything from balloons in cars to turns in your system.

Ever wonder why some exhaust systems perform better? It's all about the bend. Properly shaping the runner reduces turbulence and improves pressure, leading to a smoother flow and better performance. This technique is key for optimal engine efficiency.
