hiya all
I have a turbo smart blow off valve on my 2007 xr5 which I do luv
whats the purpose of them besides the nice woosh sound ?
they help the turbo in some way ?
im in Victoria are they illegal ?,if they are why ?
is it possble to mod the blow off valve to make legal ?
I heard in vic you are only aloud one intake mod!
so what would you call intake mods on our car ?
thanks fellas
cheers

so what no ones knows about or cares about blow off valves is it????!!!!

You will usually upgrade the factory compressor bypass valve on the turbo on these models or you can block it off with a plate and run a conventional blow off valve. Recirculating it to the intake would satisfy the rego authorites
In my experience the focus guys are more interested in trying different bypass valves chasing vl turbo levels of dose, than anyone in the Volvo world.
Vent to atmosphere is the main issue with the rego authorities
I like the turbosmart dual ports

so does that mean my dual port does not vent to atmosphere ?
timbo
It does vent to atmosphere just not as obvious to a police officer/vehicle inspector as a giant shiny hks blow off valve in the engine bay.
Vent to atmosphere can be helpful on these engines when running higher boost as it can help prevent cracked liners.
It's adjustable so you can fiddle with it if you feel there's a particular issue with it
