Compared to a 2.25" trumpet, these velocity stacks deliver superior high-RPM torque and throttle response, making them ideal for motorsport and performance-focused Porsche builds. With a standard 65mm mounting hole pattern, they’re designed for easy installation on a wide range of custom and carburettor-based setups.

Each velocity stack is sold individually and built to withstand the heat, vibration, and stress of competitive driving — offering both technical performance and sleek carbon aesthetics.

What Do Velocity Stacks Do?
Velocity stacks (also known as intake trumpets) are engineered to improve the airflow into the engine’s intake system, smoothing the transition of air and increasing volumetric efficiency.

Core Functions:

• Increase air velocity into the throttle body or carburettor.
• Improve top-end horsepower and torque output.
• Optimise pressure waves for enhanced combustion efficiency.
• Smooth airflow and reduce turbulence at the intake mouth.
• Deliver sharper throttle response at high RPM.

In short, they allow your engine to breathe more efficiently, resulting in better performance, faster throttle response, and improved sound.

Why Do Velocity Stacks Fail or Need Replacement?

Over time, velocity stacks — particularly older aluminium or plastic types — can degrade due to heat cycling, vibration, and exposure to contaminants.

Common Causes of Failure Include:

• Cracking or delamination from extreme heat and vibration.
• Corrosion or fatigue in metal-based versions.
• Airflow restriction caused by dirt or damage.
• Poor fitment leading to air leaks or misalignment.
• Material fatigue from repeated stress during performance driving.

When velocity stacks weaken or distort, airflow becomes uneven — reducing efficiency and potentially causing imbalanced fuel-air ratios or power loss.

Why Upgrade to Rennline Carbon Fiber Velocity Stacks?

Upgrading to Rennline’s carbon fibre design provides enhanced durability, lower weight, and optimal airflow characteristics — ideal for performance-focused engines and track cars.

Key Benefits:

• Increases torque and top-end power at high RPMs.
• Lightweight carbon construction for reduced mass and improved airflow.
• Precision 50mm height ideal for performance tuning.
• Improved pressure pulse frequency for enhanced throttle response.
• Direct-fit design with 65mm mounting holes.
• Sleek carbon fibre finish adds a professional motorsport aesthetic.

Rennline’s carbon fibre stacks combine engineering precision with performance-driven design — perfect for those seeking peak airflow efficiency and style.

Carburetor return spring for Solex 40PII-4.
This spring is used on Solex 40 PII-4 carburetors fitted to Porsche 356 and 912 models. It mounts to the throttle linkage / butterfly lever on the carburetor, hooked between the throttle shaft arm and a fixed point on the carb body or bracket. 
Sold each.  There are two springs (for dual carb setup) on cars with twin carburetors.

Fits:
Porsche 356 (1950-1955)
Porsche 356A (1955-1960)
Porsche 356B (1960-1963)

• This spring mounts on the throttle mechanism and provides return force, retracting the throttle valve (or linkage) when the accelerator is released. 
•  Provides tension that ensures the throttle valve doesn’t stick or hang open, which maintains safe and predictable engine operation.
•  Helps maintain consistent throttle response and prevents the linkage from going “over-center” (which could cause the throttle to stay open).

With age, the spring can weaken, fatigue, deform or corrode, reducing its ability to pull the throttle shut securely. Proper replacement restores crisp throttle response, safe idle return behaviour, and reliable drivability. Using a matching (OE Match) spring ensures correct tension, length, hook geometry, and compatibility with the carburetor’s original design.
