Full Version: Easy Way For Blow Off Valve Sound On A Mk2 1.8 TDCi???

I was considering buying a dump valve for my focus as its my first car and treat it like my baby. I just wanted the valve purely for the sound by the way.
The other day i was fiddling about with the intake to see what it would sound like with a cone filter and i disconnected the hose from the airbox and started her up and give her a rev, and i discovered that when i let off the throttle the blow off valve sound i'm looking for is actually there. So i was wondering if the car already has the valve there and if so how can i amplify the sound without any major mods.
I was also wondering about the small hose on the intake. It is located on the hose that runs from the airbox to the turbo and runs off that hose and into the head of the engine block, i was wondering whether this is the hose that recycles any air from the turbo when you lay off the throttle e.g. from the blow off valve. So whether i could redirect this hose into the open air and fill in the hole in the intake left by it, whether this would give me the desired sound and also most importantly, not make it sluggish.
If i'm wrong please correct me and give me ideas on how i could get the blow off sound i'm looking for.

Thanks in advance,

Tom :D

For a really good blow off sound feed your air intake with a good portion of vindaloo wait for a couple of hours and then release any pressure build up from the dump valve which will also produce the loud blow off sound you are looking for.
