sheep dog

[Tang0]

can you still get the sheep dog dump valve ??? from what i believe it dumps enough air to atmos to be good for the turbo, but leave SOME air in the system for build up boost, also make a high pitches whistle, a la 'the fast a furious' film with the black hondas at the start ...

Eeeerrrrr, sorry mate but I dont have a clue what youre talking about :( Any hints? Any links to websites featuring them?

Err, I think you're going to struggle to get hold of these at least in the UK Bren. "Sheep Dog" aka "Prof" are Japanese, best known for their exhausts....

Heres a link anyway to a US company which has them http://www.jspec.com/sheepdogbov.html

Can't find a Jap website for em sorry.
