BOV sound changed

[Madcap]

Not that it makes much difference to me, but when I was running the t25 my bov was quite loud. Now that I'm running a 16g it's not nearly as noticeable. Any ideas why?

Are you running lower boost with the 16g?

Are you running lower boost with the 16g?

Nope, I'm running 22 on the 16g

You have any boost leaks?

You have any boost leaks?

None that I'm aware of. If there is it's very small. It's certainly not noticable.

What kind of BOV you have on there?

The higher pressure flow from the 16g flows differently than the lower pressure flow from the T25. Different flows, different turbulence, different sound.

it's a type s

yea pretty sure it's just the difference between the turbos

yea pretty sure it's just the pressure difference between the turbos

Brining this back. What else can make the bov change sounds? Can bad turbo seals cause the bov to change sounds?

Change in pressures change in piping, turbo etc. Anything that changes airflow or is less sound deadening. Bad turbo seals? No. Never happened to with three different t25s.
