Goran,
Are your two turbos identical? I was under the impression some twin turbo setups use two different turbos so they complement each other throughout the engine's powerband.
If they are different units, wouldn't the engine be out of balance in your setup with each bank having significantly different power bands? AND again, still assuming that the turbos are different, would averaging boost pressures in the shared MAP block really be appropriate for determining fueling, spark, etc? Seems like that wouldn't be a good idea, unless the cross over is large enough to truly equalize pressure between the two banks of the engine.
I guess in thikning about this situation and potential issue(s), I'm guessing your two turbos are identical and that you can use smaller mass turbos to limit lag, but also allow high rpm breathability.
Just curious.
Maybe no twin turbo situation actually uses two different units?
Sorry for the dumb question.
Doug
