larger turbos have the same flow rate at a lower boost.

a supra with stock turbo can flow lets say 500cfm at 20 psi. but its very hot air.
but upgrade the turbo and you may get 800cfm at only 10 psi.

this would make more power. at a lower boost.

the draw back is more lag.


numbers are just examples, so all nitpickers go screw off.
