Well after seeing the above design, the exhaust side makes alot of sense, but I'm still having trouble understanding why the air from the larger turbo has to pass through the smaller one, wouldn't the smaller compressor become a bottleneck at a certain level? What would happen if you ran a manifold like the one above, but had the compressor sides set up like normal, eventually merging before the intercooler?
