225 Wastegate info

  1. Hi guys! I'd like to know how the wastegate works whit the pressure. In a stock engine the turbo works at 0.9 bar, right? So, over this pressure the wastegate bypass the exhaust gas...but if there is a 1.4bar pressure (for example after a remap) i should fit another actuator whit a stronger risistance...over 1.4 right? Or the standard actuator works over higher pressure, for example over 1.5bar? I don't know how the standard actuator is calibrate! Thank everybody and sorry for a not perfect english! :laughing:
     
  2. The pressure is controlled by the ecu that tells the n75 valve how much pressure to send to the actuator.

  3. Ahhh...ok! So it's controlled by ecu and doesn't works by turbo pressure! Thank you very much :sweat::sunglasses:
     
  4. In short no it doesn't work directly on boost pressure alone. There is a valve that allows a set amount of pressure to the actuator which is controlled by the ecu.
