You are absolutely right about the Talladega speeds being lower in
version 1.2. This was done intentionally by Papyrus in attempt to make the
speeds more realistic with respect to the real life track and also to make for
more competitive racing. If you still want to go fast with the restrictor plate
on, bolt on some Hoosier tires, jack the tire pressure up to the maximum (60
lbs), put all shocks to maximum stiffness, minimize rear spoiler, and turn up
the temperature to 120 degrees. This should get you lap speeds in the 197 mph
area and hitting 200-201 at the end of the back straight. (But your competition
will also be faster too, so it's all relative...).
