To a point of course.
I have made 575 RWHP through a 2 1/4 inch TB on my Sons Toyota.
At what PSI?
I would think that with as big of an engine this is and the fact that he's already got a bigger intake, the 102mm TB would offer some benefit. Dramatic, no but a benefit nonetheless. I'm sure the diameter of the UICP would play some role in that as well.
