Anyone got any engine bay pics of the Delta S4 or others to see how they did it?

The only one ive seen in detail was the PowerEngineering Mk1 Fester and that had a turbo blowing into a rootes type supercharger just before the inlet manifold.

Is the Delta S4 like that or is it one with the "other" type of supercharger (centrafugal? you know the one that uses a big turbo compressor wheel) before the turbo, and the rest of the piping as on a normal turbo?

(Im guessing the rootes type as it sounds madder and they usually do)

Anyone got any decent engine bay pics or anything?

(And no, wouldnt even consider doing it to my car, ive made the thing less complicated and easier to work on, not harder, lol(
