I removed the silencer ring from the turbo. It really did not change sound or power that I could notice. I was going to put it back in, but didn't get around to it. The strange part is my fuel milage has gone from 14.3 up to 16. I am guessing that it was just an anomoly. I have checked my milage manually against my computer and it is always spot on the money. I guess I will have to check it manually again. Any ideas? I ain't complaining just a curiosity.

 

Removing the silencer ring...should...

- have no impact on fuel mileage
- have no impact on power
- change the turbo sound a little

And be cautious about putting it back in.

I did and when I barked the Turbo the next time...the Silencer Ring blew out and could have chewed up some Turbo Fins, but luckily I caught it in time.

 

thanks for the good advice...I am leaving it for now to see if the milage keeps up. Then I will carefully re install.

 

Pardon my ignorance, but can you define "bark my turbo"?

thanx!

 

It's a condition where when you have the turbo spooled up real high, and you get off the throttle, the turbo "Barks" or "Coughs" (stumbles). For the record, this is a bad thing. For some reason, I hear about it more from the auto crowd than those of us who row.

 

I would normally have to agree that removing a silencer will not yield any more power. However, I installed a torque tube with the factory air box and yes it did get louder and it also is more responsive. I wasn't expecting the power so its not like I am trying to convince myself its there b/c it definitely has a peppier feel to it.

 

"Bark my turbo" = surge the compressor. It's a condition where the compressor doesn't have enough flow for the pressure it's putting out and flow actually reverses. It does terrible things to big centrifugal compressors that I run all day, tears up thrust bearings and gearing. Can't be good for our little turbos either.
