Purely academic... but i have to ask it here because asking on a place like vortex will net 10 pages of flames and no answers.
This all came from a video of a twin charged diesel benz on a drift course using an eaton M90 and a GT45? (i think). so we were hanging out in the shop and arguing how it would work, and nobody really won the argument... lol
If one were to twin charge a diesel, using a roots or twin screw, can it be done without any bypasses? not including the turbo's wastegate. Ive seen the TSI diagrams on how they use bypasses to make it a sequential setup... but thats not really what we were talking about.
which order would they be placed in order to not have a restriction?
If you go airbox --> turbo --> super --> intake manifold would either a roots or twin screw become a restriction or would it just compound the pressure made in between the turbo and super?
if you go airbox --> super --> turbo --> Intake manifold would the super become a restriction because the turbo (once spooled) wants to suck in more air than the supercharger is sending through it?
either way should be able to use a bypass to send air past the supercharger instead of through it once a certain pressure is met... but i was leaning toward the first one as the "right way"... or maybe both scenarios are true, and it NEEDS a bypass someplace. I dunno, thats why i seek the wisdom of TDIclub.
