F30 320d...Air intake options?
Discussion
I'm quite interested in air intake options, primarily to increase the noise of the turbo spool and waste gate (if that's the right term).
I was watching a ton of YouTube videos today. An interesting but stupid video of some guys who stuck a filter direct to the turbo on an e90 gave some interesting turbo chatter. Is this always happening but silenced by the associated piping / silencer?
Other videos showed induction cones which I've never had on a turbo or diesel motor, but on naturally aspirated petrols are quite loud.
The logical option would be to pop in a performance filter such as a k&n (maf issues a myth?) or pipercross (foam, but saw a video on YouTube of someone moaning as theirs had broken up and could have been ingested)
Has anyone done this on a 4 cylinder diesel (mines a euro 320d) with decent results to primarily, sound?
Are there any air box modifications that can increase noise?
Advice appreciated!
