Anyone run a custom twins setup?

been thinking, i have an extra turbo and was thinking of running a custom twin setup in my 96..

as in leaving the first one in stock position, then a custom DP (like a 12" elbow) to feed the other then from that a hood stack. not sure on the intake side piping yet..

but has anyone done something similar? is it worth doing? ive see parrarel setups but i dont really like that.

and if i do it i would be doing head studs, HPOP and maybe injectors, would i need them? im running split shots right now. should i upgrade to stage 2's? anything else should i upgrade as well?

96 7.3L, RCSB, Race truck

To do a compount rubo set up, the 2nd turbo has to be larger then first. Other wise it will over boost that 2nd turbo to be inefficent.... but u didnt specify what ure 2nd turbo laying around is

30-35 pounds? they dont hold up to well at those kind of pressures as far as I know. Havn't ever hit those numbers, just what I have read around.

When running a set up in compounds, one has to be actually larger in size then the other. Otherwise no gain is obtained. Changing the ratio just changes the spooling characters, not the actual flow of the turbo in cfm.... well maby a little but not in the amount needed

So, if you run parallels would that mitigate the rule used for compounds where one is bigger than the other? Just curious.
