I'm of a different line of thinking here, I'll post my thoughts under these two posts. Set me straight
"Originally Posted By: NexxussianFood for thought, as the lower the restriction before the turbo, the less heat it builds for a given boost (within it's design limits). "
"Also, as the intake restriction before the turbo is less,the turbo will spool up faster.Also the same goes for the exhaust system.

My thinking
Less restriction before the turbo, the less heat it builds? So if I double the size of the carb, but am running at part throttle, it builds more heat? That would enfer that full throttle is better than part, as a small carb wide open or a large carb only half open would flow the same.
The same question goes with the "spool up faster". Ever put you hand over the end of your shop vac. Does it speed up, or slow down when you restrict the flow.
In the end, total power is restricted, a good thing when working with a stock engine internals, and that the small carb goes fat reducing the intake heat through vaporization, combustion temps are reduced which reduce detonation, and exhaust temps go down when the engine is rich as well. Lean=hot, rich =cooler.
