Does anyone have comparison info on a single vs. twin turbo setup on an M30? I realze the simplicity of a single setup but when I consider the space I have (E3) and the flow I'd like to maintain (two manifolds vs. one) the twin setup starts to make sense despite the complexity. It seems that most single turbo systems use a T4 or T3/T4 mounted on a log manifold while a twin setup (like an Alpina B10) could utilize two (physically smaller) T28s on two better flowing manifolds, what's better? It would be interesting to hear from both sides. Also, any experiences with plenum-integrated liquid/air intercoolers also on an M30?
