The Lancia Delta S4, is the supercharger or the turbocharger first?

Q: Or is one for one half of the engine and the other for the other half? no thats stupid...... alos why is it in that particaliar order...

A: According to: http://forums.dieselstation.com/index.php?showtopic=10674 "On the S4 the order, from the air intake was turbocharger, intercooler, supercharger, intercooler, inlet manifold (schematic diagram). Once the supercharger became less efficient, at higher engine speeds where the turbo performed better, a bypass allowed the turbo to feed the engine directly." I saw the S4s on the RAC rally in 1985 - awesome, still remember having to jump off the track in the Yorkshire forest as Alen came along. Still got some photos somewhere. Oh, sorry, I digress...
