NRW’s 4″ Turbo Velocity Stack, suitable for many S55 and S58 single turbo setups, and many more!

NRW’s single piece billet aluminium 4″ velocity stack with 1/8″ NPT port and 12AN intake port!  This velocity stack offers more than any other velocity stack on the market.  Milled from a single piece of 6061 T6 aluminium , this 4″ velocity stack adds performance, style, as well as solving many issues associated with vent to atmosphere catch can systems.

Performance – gained by smoothing out the airflow and accelerating it as it enters the turbo – a major benefit over a simple screen type that covers your turbo. NRW have incorporated a 1/8″ NPT port at the top of the velocity stack to allow for either a nitrous nozzle or methanol nozzle for added horsepower and torque.

Style – this velocity stack is milled from a single block of 6061 aluminium and so offers amazing style and a screen that is milled directly into the velocity stack.  This will help from larger objects from entering the turbo intake with out breaking of degrading like the simple band screens offered on the market today.

Solves – this solves the main issues of venting to atmosphere which are smell, oil spray over engine bay, and providing a negative pressure in the catch can and valve cover.  There are serious gains made from having a negative pressure in your system which gives you freed up horse power lost by back pressure in your engine case due to blow by.  Think of it as a small vacuum pump.

This velocity stack can work with any 4″ intake single turbo.  This stack can be adapted to any catch can system that uses a 12AN out or could be stepped if needed to get to 12AN at the velocity stack.  This stack pairs well with NRW’s S58 catch can system, S58 billet valve cover, and their S58 single turbo kit. All manufactured in the USA!

The Velocity stack is offered in either Anodized silver or Anodized black and can be powder coated any colour for an additional charge.
