NASCAR Racing restrictor plate Q&A (and comment) Q: What IS a restrictor plate, and how do you turn them on/off in NASCAR Racing? A: A restrictor plate is a flat plate with four small holes drilled in it. It is bolted between the carbuerator and the intake manifold (or somewhere near that) and restricts the air going into the engine. This restricts the horsepower that is produced and therefore the speeds of the cars. The NASCAR Racing game only has one track (Talladega) that makes use of the restrictor plate. Do the following to 'turn off' the restrictor plate: Using a text file editor, open the file in the NASCAR/TRACKS/TALADEGA directory named TALADEGA.TXT The third line of the file begins with the letters 'SPDWY' and then a series of three numbers. By default, the first number is a '1' (indicating 'on'). Just change the '1' to a '0' and then save the file. To restore the plate, just change the '0' back to a '1'. Comment: Current 'real-world' NASCAR rules require the use of the plate at Talladega. The game gives you the flexibility to turn the plate on and off for the sake of making things more fun and interesting.
