Sounds like a BOV on an N/A car...

[kirks]

I Recently did a k20a2 motor swap into my ek.

* Stock k20a2

* K tuned headers

* 200cell cat

* 2.5'' custom exhaust to a vibrant muffler

* custom Cai with a blox velocity stack.

* Hondata k100

Heres my current symptom

Everytime I Clutch in and change gears I hear an air whooshing noise like a BOV.
I find it weird because my car is n/a and the sound is quite noticable daily driving (windows up, no music playing).

What are your thoughts on this?

Thanks guys =]

lol probably your intake broo i got that noise too

[cihanvtec]

its ur intake man, i get the same noise every time i clutch! its louder on a cold morning!

[kirks]

Its just weird because the sound wasn't there last week and just started this week =/

Its also very loud (abnormally loud if you asked me)

It was loud enough for me to get pulled over and get defected for == (the cop was standing outside and I happen to drive pass him and it got his attention because Im a p plater and it made a bov sound)

Didn't get done for high power vehicle of course lol. Just too low.

My old b18c didn't do this at all even with an intake.

So I"m just confused that's all.

its just nice solid vacuum bouncing back out via the intake filter
the air under vacuum in the intake arm being shut off by the butterfly in the throttlebody and shooting back out your intake
iv had it on all my cars with intakes - its more noticable on larger filters than smaller ones
different engines will have different results on how they breathe as well

deleting the stock resonators in favour of a CAI will make it really loud and the velocity stack will trumper the sound

what clutch did you put in? usually in my friends dc2r it makes a whirring/whoosh sound cause of the sport organic clutch

[SuperJDM.]
