2 X WEBER 45 DCOE Dellorto 2" Ram Pipe Velocity Stack Intake Trumpet

Pair of Vortex Velocity Stacks – 2" Tall, 45mm Bore

Upgrade your induction system with a pair of IPNG Vortex velocity stacks, designed for 45mm Weber and Dellorto carburettor applications.

Featuring a smooth bellmouth entry and integrated curved guide vanes, the Vortex design is intended to help smooth and control airflow entering the carburettor, reducing turbulence at the intake and promoting efficient airflow.

With a 45mm bore, 65mm mounting stud spacing and 2" overall height, these velocity stacks provide a bolt-on solution for a range of larger Weber and Dellorto carburettors.

Specifications

Vortex Design

The Vortex velocity stack features a smooth bellmouth entry designed to reduce turbulence as air enters the carburettor.

Integrated curved guide vanes within the stack are designed to help control and direct incoming airflow, providing a smoother transition into the carburettor.

The Vortex design focuses on airflow optimisation, while providing a distinctive alternative to conventional straight-bellmouth velocity stacks.

Installation

Difficulty: ★★☆☆☆
Estimated Time: 15–30 minutes

Installation uses the original carburettor mounting studs and fixings, meaning no permanent modification to the carburettor is required.

Position the velocity stacks onto the existing mounting studs and secure using the original hardware.

Air Filtration

The required air filtration arrangement will depend on the individual vehicle and engine setup.

For exposed engine bays or vehicles regularly used in dusty environments, we recommend using a suitable foam filter over the velocity stacks to help protect the engine from airborne dirt and debris.

Air filters are not included.

What's Included
