So being Sunday I haven't done very much lol and was having some out of the box thoughts on a compound setup. But before I get into it, let me start off by saying I am aware of how compounds work and have built multiple sets in the past. But I had an idea and was just curious if it would work or not.
Generally in a compound setup you have the smaller charger(primary) on the manifold and the larger charger(secondary) fed off of the exhaust gasses coming out of the primary charger. And the air sucked in from the secondary and pushed into the inlet of the primary and then into the intercooler/intake of the engine. But....
What if one was to build a compound setup the opposite way. By that i mean secondary on the manifold and primary downstream. And what i was thinking is that there would be a wastegate on the manifold that would divert exhaust to the smaller charger under low boost situations and close at a desired boost level (so basically its working the opposite way of a normal wastegate) keeping all the exhaust in the larger charger. This would also require a wastegate between the large charger and the small charger on the exhaust side to bypass the small charger and direct into the downpipe to keep from over spinning and high drive pressure.
And in doing so I would think one would be able to get the most out of the larger secondary charger and no have near the issues with drive pressure, and possibly be able to make more hp due to the fact there is not such a restriction on the manifold and you would be able to drive the secondary harder...
Im not sure if something like this has ever been done or tried, it could be a dumb idea lol but I guess it never hurts to try to think outside of the box.
But feel free to leave an explanation if you would like id be curious to what everyone thinks about this idea, good or bad and why it wouldnt work.
Thanks.
