I wasn't sure where I should post this, so I decided here would be good. I've been really bored and was watcing some car videos of mine that I have. And a few of them were of some Supra's and I noticed the difference in bov sounds. This is prolly a stupid question but I'm curious, why is it some bov's have a sort of flutter to them while others have a loud ppssshh(only way i know how to describe it). Anyways I was just curious because I think the flutter sounds very sweet. I was thinking maybe large amounts of boost creates the different sound maybe? I'm sure I'm probably wrong though.

 

I think it's just dependant on the BOV manufacturer and how much boost is being run. Not sure, I'm not too familiar with FI. :happysad:

 

im not BOV expert...but the amount of boost and the design of the BOV probably creates the different sounds. :dunno:

ive never heard a honda make that fluttering sound you hear on bigger engines sometimes.

 

Depends on the amount of boost.
Also, it might be the wastegate...I think that makes a sort of "fluttery" noise. :dunno:

 

If I could post this video it would give a very good example of what I'm talking about, but theres no way to do that is there??

 

n/m i lied i think i know how

 

Ok well hopefully this works. Theres one point at about 50 seconds in the video where you can really hear what I'm talking about. Hope this works.

 

It didn't work? I tried the attach file option?

 

you cant attach vids....:no:

 

Best Motoring video: Turbo vs. NA, the Silvias have that fluttering sound. :naughty:
