Actually,
I suggest some quarter mile runs. The reason why is b/c the difference is going to be the air flow, which would be hard to define on a dyno. Now, if you take the car and put the stock airbox back on and do a quarter mile run, or even a eight mile run, then do the same with the 'new airbox' you would get an accurate measurement of what was gained. (and you could calculate and correct for the varing 60 foot times as well to be completely accurate)
Just a thought,
