not sure how that renaming process is going, but to my mind the only issue I have with "slamJet" is that it's a hard name to get flowing. This is only my feeling of course but it does feel as if there is a bit of a bump in the middle of the title due to the j sound being... harder than the m sound. almost like you have to stop after saying 'slam' and then start a new word in 'jet'.

I don't know if there is a particular meaning to slam that alludes to something in the game so I'm going to assume there isn't one.

with that in mind could I suggest:

"JetWash" it's a term describing the turbulence you get when one vehicle passes through the jet stream of another vehicle, usually in fighter aircraft.
it also has another name: "Wake turbulence" which might be more accurate as a description.

in any case I found that both of these terms, while describing somewhat well the type of game it is, also roll off the tongue quite nicely..

just a thought.
