Fuzzy Math

I'll throw one more point in. Gains in power from decreasing restriction to airflow are most noticible in the higher rpm ranges. There is a point of diminishing returns which depends on the quality of cylinder to cylinder fuel distribution and charge stratification. Large plenum volumes and more direct flow paths make it easier to obtain even fuel distribution under wide open throttle conditions. Exhaust and engine of course play a role too.

In line with what others have already posted here, check out the first two posts here: 100 cfm more with anular and downleg boosters can't beat AFR
The most important thing for maximizing WOT power is get the timing and fuel mixture right.
If the carb is ballpark correct to begin with, then really all that's needed is some jets and a 1/4 mile drag strip.
