Anyone ever notice heating/cooling ductwork in your house or in big buildings(home depot, ect). Take a look at where the duct starts at the heater. Its damn big and large in diameter. Then take a look at how big the ducts are at the register openings. The ducts will go down in diameter the farther away from the fan source. Going from a large pipe, to a small pipe, increases air flow velocity, which in my comparison, will keep the air moving fast at the register, instead of slowly if the duct work was the same big size at the register opening. I fully agree with Bill and others, a larger TB isnt going to help for stock NA apps, it basically just changes how much air enters the engine with the gas pedal. Instead of pushing the gas half way down to reach lets say 35 mph in 3 seconds, put the pedal down half way on the 60 mm, you will accelerate faster in lets say 2 seconds to 35 mph. The larger TB just flows more air per given throttle plate opening over the stock TB. I really want to see what the 60 mm can do with a boosted setup...dyno wise anyway.
