Ok, I just got through installing it. Took it for a little ride... first impression... the turbo sound is ridiculous! I still have my silencer ring in, I don't think I'd be able to handle any more whistle than this. That's just me anyway.
On that note, I'd like to ask something. Forgive me if it's a ignorant/dumb question.
With the exception of removing the silencer ring, is the audible level of the turbo directly correlated to the amount of air it is receiving? And is the amount of air it receives directly correlated to how quickly it spools up?
