In Part 9 of our RB26 Head Porting Series, we expose the critical mistakes made by a previous porter and show how to correctly shape the RB26 exhaust ports for maximum flow. One of the biggest errors? Treating the port like a mandrel bend, which chokes flow and disrupts the pressure wave movement.
Here’s what we cover in this episode:
🔧 Why a mandrel bend shape is WRONG for optimal exhaust flow
📏 Why the short side needs MORE area than the long side for better scavenging
🔄 How a trapezoidal port shape with radii helps turn the pressure velocity wave smoothly
🔥 How to reshape the RB26 exhaust ports for improved power and efficiency
Getting the exhaust side right is just as important as the intake, and we’re breaking down exactly how to do it properly.
