I'm not quite sure what you're trying to acomplish...From what school has taught me its the Velocity of the gas that has the biggest impact on spool. Combine that with Volume, and you're in happy land. Velocity is proportional to heat and heat to energy.

blue TII....wow, I want that setup. what specs would I need to boost that fast and hold it till redline. you wouldn't wanna sell that one in the picture would you. I don't really wanna go full aftermarket because that involves alot of time & $ and I don't have alot of either.
The only thing I had going for me was spool-up, but I downsized my turbo back exhaust size to 3" to stop boost creep and spool-up suffered. I am going to try the 3 1/2" downpipe to 3" rear section to see if I get better spool-up and still restricts the top end enough.
Just get a T04 set-up w/ a small(ish) hotside and put a 3 1/2" or 4" turbo back exhaust on it for good spool up.

That is why the huge 3 1/2" and 4" exhaust work so well to provide the low end torque as boost comes on very early.
