Riley 0 Posted September 8, 2006 alright peeps :) Could somebody point me in the direction of threads covering this? im useless with the search :oops: Or if someone could explain how the isv/isv re=route works? i cant just get my head around where the extra psi comes from and wotnot. Cheers,Neil. Quote Share this post Link to post Share on other sites
Riley 0 Posted September 8, 2006 Just tryna get my head round this... I thought the isv sucked into the inlet manifold? so how would it bleed off into the boost return pipe? :? or does it work both ways? Neil. Quote Share this post Link to post Share on other sites
W3RKD 0 Posted September 8, 2006 the isv opens when the map sensor reads over it limits. ie 5v' or 1bar. Quote Share this post Link to post Share on other sites
Riley 0 Posted September 8, 2006 cheers darren,sorry m8 i know this has been covered a lot and probably a bit labourious keep going on about it for ya.... So the isv will bleed over boost at 1 bar,but which way? surely only from the inlet manifold into the boost return pipe? cant understand how if the isv is sucking rather than blowing :oops: Quote Share this post Link to post Share on other sites
Rustynuts 0 Posted September 9, 2006 Yeah thats it, bleeds into the boost return. I think the reroute returns it into the boost intake pipe, thus retaining pressure Quote Share this post Link to post Share on other sites
