Try this out:

It is a basic 5 second title and has 4 parameters:

The zoom effect will start at Start Offset Frames (gives the viewer a chance to see the title before animating, or set it to zero to begin zooming right away.)
The Z Change Rate will zoom the text Star Wars style for negative values and zoom the text toward the viewer with positive values. Values near 0 will vary the text only slightly and 0 means no change.
There is a fade out (in frames) if you don't zoom the text all the way (and quite necessary for zooming the text away from the viewer.)
The Y Position parameter will give it a better "fly-by" effect -- this should be keyframed from 0 at the beginning to a few pixels either direction (you'll be able to tell.)
If you need it to go faster, just shorten the title in the storyline; conversely, if you need to stretch it out some, lengthen the title in the storyline.
If the title looks fuzzy/pixelated when animating - and that bothers you, just select it and render it (Control-R) then play it.
This will do the effect you want, easily.
