I don't know about a "typical" increase in HP, but you can imagine having 110 degree intake temps plus the turbo heating it up a bit more....let me throw some random numbers at you....110F intake temp + 50F turbo temps = ....where as if you had a RAM you can lower the intake temps down to 70-90 (depending on ambient temps) and then add the 50F from the turbo. You can see how the combustion chamber air will be cooler with one than without, thus reducing knock = pulled timing = lower performance.
I used to have 110F temps out here in Hawaii during the summer, I fabbed a partition and my intake temps dropped 20F. My bubby did the same thing and added some ducting from the opening I stated above and he sees ambient temps at idle and temps below the surrounding air's temp while driving. Without the ducting I see 10F above him. He didn't use huge ducting either, just your run of the mill black clothes dryer ducting.
The cool thing is that you don't even know the duct is there unless you bend down and let your eyes adjust to the darker background.
