AMS Top Shop Engine build..the quest for 1000hp on 100octane!
Initially yes but because we were short on time it ended up being a large single.
It wasn't a True Twin turbo setup because of the valving system. The header would spool the smaller GT28RS then based on where we wanted we would open the valves allowing the already spooled GT42R to unleash on the engine. Getting the valves to work when we wanted was something we just ran out of time on. It can still work but we will have to try later on.

This setup should still be recreated and dynoed for fun!!!!
Nope, on the compressor side, you have the largest turbo first in line. The maximum mass flow rate of a sequential turbo system is dictated by the turbo inlet that is pulling air from the atmosphere.
Once the air is compressed, you can get away with a much smaller turbo for the second stage. Play around with the corrected airflow and pressure ratio equations available for compressors and you'll see what I'm talking about.
If you want to see it in action, look up high performance turbo diesel applications. Pretty common to see dual stage and even triple stage systems where the first stage is some GT60 that can flow 200+ pounds/min and the second stage is just the stockish 40 pound/min sized turbo. They typically run upwards of 100 PSI of boost on these systems.
Do you you mean GT28RS -> GT4294R ?Once the air is compressed, you can get away with a much smaller turbo for the second stage. Play around with the corrected airflow and pressure ratio equations available for compressors and you'll see what I'm talking about.

I need to go vote. When I saw those pics I felt like calling the cops on you guys. I know you're breaking some laws, because that setup is insane. How long was it before you guys settled on the idea of using two turbos?
