Scotty, i don't know if this has been covered by you. I have read mixed thoughts about turbo flutter. I have a 2017 focus ST and i recently took out the sound symposer and used that to provide a true vacuum for the blow off valve now the car has a cool sounding flutter when the boost is under I'd say 10 psi might be 7 it's hard to tell.
In your experience would that harm or cause premature wear? Or is it something that should be addressed by adjusting the blow of valve so that it vents at lower psi?
If you vent at a lower PSI you'll just lose boost. Keep in mind those things spin at ridiculous RPM's, it doesn't take much of any force to cause premature wear on the bearings and shaft. If it were my car, I would put it back the way it was. If you want a performance boost then you want the waste gate valve to not open until it has higher pressure. That spins the turbo faster, increasing boost pressure. Keep in mind that modification will cause premature wear not just on the turbo, but the engine itself.
Ok I'll take that into consideration. I was not trying to gain any power from the modification. Just wanted to delete the sound symposer because it's a gimmick where it drowns the cab with engine notices and became annoying. The other reason is that I wanted the BOV to stop venting every time I let off the gas some times for no reason and this took care of it but caused the flutter to appear as it is now not venting at lower PSI only when under boost which is what I wanted to accomplish.
The delete plate allows for a true vaccum source for the BOV and it doesn't vent everytime I let off the gas as it was doing when it was connected to a valve.
But premature wear is indeed a concern of mine. Thank you for the advice!
