ive been thinking of this idea since we got out srt. i have a 66mm over 94mm on my cummins, the small spools the large turbo. alot of Dmax guys have been putting vortecs on thier trucks with a turbo feeding in. in turn the blower creates extra drive pressure for the turbo therefore the turbo spools faster then if it was alone, ie the eurocharged turbo car.

its a great concept and alot of guys have proven it works. the only problem i see is the lack of fuel. and dont forget the turbo srt6 was pushing less boost psi wise, but more cfm. some people dont realise that there is more then just pounds of boost, cfm plays a major role. food for thought i used to have a srt-4 with a ported td04 and 22# boost i made 327hp, i went to .50 trim and at 16psi i made 324hp at 23psi i made 416hp.

heres a pic of my compund turbos on my truck.
