A friend of mine ran a similar set up on his renault 21.
He went twin turbo with a pair of T3s. The exhaust off turbo 1 blew into turbo 2 to drive that but both compressor housings drew their own air in from atmosphere, not one blowing into the other as per those pics. Obviously it works but surely doing it the way its been done in the pictures would increase the intake temps no?
