I find that I don't get a replay of an entire race (I have been practicing
passing so I have all 33 cars turned on).  I presume this is because I have
only 8 MB memory?  I get about 12-14 minutes of replay with all cars turned
on at New Hampshire.  How much memory do I need to get a full replay at, say
Michigan?

Alternatively, I suppose I can escape in the middle and save things out,
but that's a pain.

I have 16MB RAM and I can view the entire replay of a 40% race at Michigan.  
Other than that, I don't know what the limit is.

Yep. that's a way to do it.

The amount of memory required for replays is highly dependent on how much dirt
and smoke gets generated.  I've seen replay files where more than 3/4 of the
file is associated with dirt and smoke (and that didn't require running in the
dirt very much).

Here is a formula for the size of a replay file assuming you have no dirt, smoke
or crash sounds.

File size = 16 + ( ( 7 + ( 10 * NumCars ) ) * 15 * seconds )

The File size is in bytes.

Basically, there is a six*** byte header, 15 records per second with each
record having 7 bytes of fixed overhead and 10 bytes per car.  The smoke and
dirt can easily add several hundred bytes PER RECORD.
