Saw the early post and remembered to call Turbonetics.
Verified I my hypothesis that we can regulate shaft speed to a specific max rpm 30,000 was an achievable goal, with a waste gate or vgt.type turbo-charger ,teck support realized what I was asking when I referenced the BMW and Mercedes F1 Split Turbo power generation units unfortunately Turbonetics dusen't offer any 1st of 2nd gen cummins parts anymore use to have manifold to exhaust tip. He referred me to his friend at HTturbo.com. I'll call them soon.
I still think that a NA or compound setup would be wise for prototyping
