Would be nice to run 36psi from, what under 4000rpm to 9000rpm, I'm guessing due to the wider peak boost range you would want to run 2 stage pre turbo injection with a 50% flow rated secondary injector to come in before peak torque?

apart from all the obvious 'issues' its a great idea, I've done allot with Diesle's in truck racing (2 stage) and pullers running 3 stages, water injected.

not sure how useable it is though? I personally have found there is already too much power from 4000 to 5000rpm and it needs to be 'dampened' down to make the car driveable......... nothing worse than too much torque @ from corner apex, only need to look at a modern 2014 F1 car to see what I'm talking about!
