djanta Member 42 Member For: 17y 8m 17d Gender: Male Location: Melbourne Posted 03/06/09 01:14 PM Share Posted 03/06/09 01:14 PM hey guys, just curious as to what this noise maybe. recently had car tuned and 14psi actuator fitted, 4inch dump and 3.5" cat. now before the the tune and those 2 mods were fitted, I used to get a great wistle sound coming from the turbo when it was boosting, now im getting a wsh wsh wsh wsh wsh wsh sound as it boosts and have lost my whistle. ive read a few other posts on here and seen that people with the same issue were saying it could be the fact that they havent changed the thier actuator and were running higher boost, mine is brand new.ive checked all my hoses and so far havent found much wrong, ive also heard it could be the actuator trying to control the boost.I miss my whistle spooling sound, any ideas on what it could be?

I have since had various tuners tune my car (including the wog) and the noise is gone so just sweet sweet boost...I dont have the flapper mod and the actuator is standard also.I doubt it causes a problem but it is bloody annoying and sounds crap, get it fixed or see someone who can.

It doesn't seem to affect performance though but I still would have it fixed.Good luck anyway Link to comment Share on other sites More sharing options...

I just wish I could pin point what it was that's all.does anyone know how waste gate duty cycle works? and how it is set up Edited 04/06/09 03:17 AM by djanta Link to comment Share on other sites More sharing options...
