dump valves

rhubarb4 · 03-19-2008, 04:19 PM

Hello everybody im new to this forum. I have an audi S3 2000 model, i want to know if fitting a Forge splitter dump valve can affect the the boost on the car for example on acceleration, experiencing a jerking like taking your foot on and off the pedal quickly.

make sure its the right type of dump valve as u need 1 that recirculates aswell as dumping the presure i think im in the same boat as u i havent bought 1 yet but am looking at it have u had your car remaped at all as that might also be the issue as it sound like it could be a bad map

it shouldn't affect the pressure but make sure the valve is set to proper settings so it dumps and recirculates at the right time there are different springs you can install into them for different loads (psi)

You need a dump valve that recirculates the air. The ecu doesn’t really like the loss in pressure. What will happen tho is you won’t have the discharge sound but a far better than the plastic oem valve.

the ECU hates it when it doesn't have a diverter valve. I disconnected the diverters to see what it would sound like and when i got off the gas the rpms would dip so low the motor would almost cut out.

best is to buy a diverter valve, the ecu needs to repump the air back and this helps to throatul the speed i have the 2001 S3 ncie buh ive had soo much problems
