A new thought for twins - Compound Turbos? Maybe?

[Herblenny]

Hmm.. Interesting..

I wish there were more real data on these things.. What I would like to think about is, would smaller turbo getting air from the larger one eventually hit limit of one or the other. Example, the smaller one will spool first, than exhaust goes the the second, larger turbo, but the air is being pulled from the second.. Would the air eventually hit a limit as rate of pull would be different?? Also, how about exhaust rate after going thru first than the second?

Also, how about air temp?? Air seems to be warmed up already and then warmed up again by second turbo? To me, it might be better if two merges vs. one shoots warm air to the next.. Also, I've heard air temp isn't as crucial to diesel vs. rotary.. Again, thats what I've heard and I have no real experience in diesel.

again, i'm not an expert in this.. just putting down what I'm thinking in my head right now.
