+ Micro Wizard K1 "Cheap kit". For $50 you get a quality timer with a computer interface. You just need to assemble the electronics and build an enclosure for it. For $65 they will assemble the circuit board for you.

If you get/build a 4 lane timer, why not put those extra 3 sensors to work at different points on the track (end of ramp, end of curve, mid straightaway)? Then you can examine car performace as your cars run down the track at the 4 different points.

Don't get me started!! I've wanted to put timers at 1 or 2 other points. My wife would kill me!
Off the top of my head, the start (inertia) and finish (stability and wheel friction) seem to be the main areas where differences in car speed is observed.
What about the transition and first part of the straightaway?
Each point Randy listed can tell you some great information on what the car is really doing. Also might help locate issues with the track setup. Locating sensors just after each joint, you could look for sporadic spikes in times.
Oh the fun you can have, and the more aspirins you're gonna need.
