Some may not like the idea of cluttering the bay with more stuff, especially unnecessary stuff. But for me, and working as a SemiTruck Diesel Tech, I just really enjoy the sound of a turbo... is that so wrong?
Some cars come with what's called a noise pipe. Yup, you guessed it, it's a pipe that makes cool turbo sounds inside the passenger cabin. Now from what little info I gathered, most people deleted them ASAP because of this 'noise pipe' being on the charged side of the turbocharger system (after the turbo, before the TB) I would absolutely do that too, but I got to thinking. Instead of this noise pipe being on the charged side, why not fab one up for the intake side? The only cons I see as of now is that: A. It takes up unnecessary space in the engine bay, B: depending on how it's fabbed up could end up with more possibilities of unfiltered air leaks and C: You've got to be quite krafty to make this a clean mod.
There's also 2 ways to go about this depending on how you're set-up.
If you have speed density (no preturbo airflow sensor) you could use the intake pipe recirculation fitting and make a pipe run into the firewall somehow. This would need a small air filter since the turbo is technically drawing air through here.
If your stock you might use an acoustic effect (think two cups and a string as a kid) and secure a pipe to the intake pipe and run it up into the firewall. No air filter obviously.
I don't expect everyone to like the idea, but we're not all out to be crazy weightsavers and strictly performance. This mod would be intended to be a clean one with no ill effects besides the two possibilities outlined earlier. So please, I'm hoping to keep this as much of a constructive thread as possible.
