Anyone got any experience or tried this, got me thinking after watching the Lancia Delta S2 vids;

which is supercharged and turbocharged. This is one turbocharger (small) feeding another (bigger). Would make for an awesome power delivery and a very broad powerband.

Looks easy enough to fabricate, i was thinking T2 from 2500rpm, then like a td06 or summit comin' in 5500rpm obviously with a built motor revving up high or would a properly set up big single turbo be better with like nos or anti lag?

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?
