BOV sound
 

Nice day today in Houston and I was driving with the windows down. Went to accelerate and I can hear the sound of the X bouncing back off the sidewall. Couldn't help but to notice every time it shifted, I hear this BOV sound, like a swooshing sound. What is causing this? Thanks!

Do you have a turbo, bro?

Nah brahhh... Kicked that habit. Use to have a 300zx twin. :)

Can't help you then😊......I have had a few Skylines, Mazda Speed 3 and even a Nissan Stagea 260RS (which I doubt most know what that is but they are rad).

Bought an X5 as a 'grown up car' and even though my x5 is turbo diesel, I still miss that sound when you snap the throttle shut on boost (diesel doesn't have a throttle body).

But none of that helps you right!

Do you have an aftermarket intake?

the engine will retard timing and cut fueling when you upshift for a better smoother shift, sort of sounds like the engine is farting

I try telling my wife that, but I am soon betrayed by the need to open a window. :(

There is a distinct difference in my farting sound and BOV sound and that doesn't include the smell.

I also noticed a slight "hesitation" between the shifts hence the BOV sound.

Lock the windows and blast the heat. Make a game out of it. :D

kk u got problems than bro, lol

do you have inpa or gt1 or anything?
try reseting the learnt values

Wonder if your not hearing your torque converter squeal? Mine does between shifts under heavy acceleration...
