If i cared about Displacement i wouldnt have a turbo! Now the good luck, ive gotten my truck in the mid 10's with my own tuning and built the whole truck why do i need luck keeping it together, Big Power will eventually = Broken parts anyhow, like i said ill get some solid numbers for ya from going to a 88 mid frame a 91 large frame at 15#'s just stay tuned 
Im not doubting your abilitys, and I believe you missed a little friendly sarcasm....But, for real, a turbo can never make your engine hold more air IE volume is a measure of area not density. And the keeping the engine together part was just saying that you can not increase the volume (known as engine displacement) without opening it up to another atmosphere

still wouldnt change volume under pressure.
yep i know exactly what VE is and what does that have to do with what I said about VOLUME. What VE is about is preventing compressor surge and excessive heat. Here is a good read for you http://www.engr.sjsu.edu/ndejong/Com...troduction.pdf . And yes they will move the same VOLUME of air into the same engine at the same pressure, the engines volume never changes and PV=nRT. And at the same pressure they both have the same density of air if the temperature is constant, which it wont be. The smaller turbo will have to spin faster to do it creating more heat and a loss of power causing you have to add fuel to mitigate detonation. Causing another loss of power due to being to rich.
So, what you are telling me is that a larger turbo is going to magically increase the cyclinder capacity and the displacement of an engine? Good luck with that and keeping one together.

if that was true, explain how the same motor lsx 427, makes 988rwhp on 17psi with a 91mm, swapped to a 106mm and on 16psi make 1107rwhp
