A new thought for twins - Compound Turbos? Maybe?

Just remember that the more restrictive turbine needs to come -first- in the exhaust stream; if you put the less restrictive one first, exhaust will back up against the secondary turbine, and you'll lose your pressure differential, and the first turbo won't spool.

That's why in the diesel compound systems, the smaller turbo always goes first, then the exhaust runs out to the secondary. I'm not sure exactly what would happen if you ran a pair of identical twins in a compound setup.

I don't know for sure if that's what you were saying or not, but I figured I'd clarify, just in case.
