Go to the Nascar 2 directory ( you might have to go thru Sierra first.) and go to the folder TRACKS, then go to the folder called Taladega, after that go to the file that looks like a read me file but says Taladega, go in it and go to speedway, there will be a number 1 and two other numbers, change the number one to the number 0 and exit. While racing you can reach speeds of 230 mph.
