I think the calculation of 74ms and-you're-done is likely to be misleading here, what you've calculated is the time it takes an engine at WOT to evacuate a given volume. If the difference between the two pipe sizes was observable to the butt-dyno it would be most noticeable coming into throttle, coming into boost. You would need to calculate how long it takes the turbo to increase the two differently-sized intake tracts from off-throttle pressure to the target boost pressure, while the turbo's spooling up, and while there's air leaving the tract through the intake ports at a rate proportional to tract pressure.
Hi
Another issue with smaller diameter piping is the velocity of the air inside the intercooler piping.
It should give you a little hint, the fact that Volvo chose pretty large pipes even if the stock power levels of the 230FT even are modest by todays standards....
