High Flow Valve Kit

This valve kit is an evolution of the FMARSDV dump valve Forge markets for the 8P chassis RS3. It was developed for those who have tuned, or plan to tune, their 8S chassis Audi TTRS or 8V chassis Audi RS3 in excess of 450hp. Audi have seen fit to not change the design of the OEM dump valve from the previous RS3, so the same issues are carried over to the new 8V chassis.  Namely, it was observed that cars over 450bhp were randomly getting errors from the stock solenoid dump valve not functioning. While the stock valve will operate as designed, with the boost level necessary for 450bhp the stock valve couldn’t move the volume of air it needed to.  The ECU was seeing too great a positive boost in the MAP readings between gear changes and assuming the stock valve wasn’t functioning correctly.

Forge looked closely at this issue and noted that there would be no real fix for this as the size of the hole for the valve is too small in the stock elbow. It was then decided that they would re-design and produce their own elbow, allowing a much larger DV port, which in turn would allow fitment of a larger valve to take advantage of it. Forge also improved the internal flow of the elbow and removed restriction within the valve. The elbow design has been changed by Audi to accommodate a different throttle body, so their design has changed too.

With the engine management on this engine being MAP based rather than MAF based, which is unlike many other Audi engines, Forge incorporated the option into the kit, of being able to run as a recirculation valve or with an atmospheric discharge/blow off.
