Description

We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner

The Splitter is a truly remarkable valve that gives a combination of blow off and recirculation valve operation, all at the same time. Specifically designed for the many turbo engined applications that operate metered airflow management systems. This means you get all the noise of the blow off valve whilst retaining the compatibility with the recirculation requirements of the engine management system. As a bonus we also offer the ability to convert the valve to recirculation only mode for those times when stealth running is required.

This valve uses a Brass piston which utilises new sealing technology along with a variable spring preload, incorporating a ratchet type top adjuster that will allow for the positive and precise adjustment to match the valve to your engine. This is achieved by using a unique single, conical, progressive rate spring. It can allow for the retention of boost pressure over a wide adjustment range. This unique spring design also allows for unrestricted piston travel and flow volume regardless of the amount of pre-load adjustment added to the spring.

 

Other manufacturers’ valves use cylindrical springs with adjustable pre-load, which often experience restricted piston travel and a reduction in flow volume. It’s not a catchy sales phrase, it’s the truth. We prove it with every product we manufacture.

Note: This valve requires installing the opposite way to the original Bosch Valve. The side pipe is fit into the Turbo Intake Hose, and the base pipe connects to the hose that runs to the boost side of the turbo.

In The Box:

  • 1 x FMDVSPLTR Valve
  • 1 x Valve Blanking Cap
  • 1 x Instruction Booklet
  • 1 x Forge Sticker

To service this valve, access the valve piston by removing the 3 cap screws at the base of the valve. Clean the piston chamber using brake cleaner or similar cleaning fluid before installing the new spring and piston. Please observe the correct spring and piston orientation when installing the serviceable parts, as seen in the attached drawing.

Adjustment guide

First turn the valve adjustment knob all the way down in the anti-clockwise direction. It will adjust the spring it to its lowest tension. Then turn the valve adjustment knob in the clockwise direction to the appropriate tension level, as set out below.

  • Standard engine – 16 clicks.
  • Stage 1 remap – 21 clicks.
  • Stage 2 remap – 25 clicks.

These adjustment recommendations are a general guide. Your engine may require fine tuning by 1 or 2 clicks in either direction to achieve optimum performance.

There will be no significant performance benefit adjusting the valve over 30 clicks as the spring will have reached its maximum operating tension.
