We played this game way back in the day and it was good clean fun. Obviously, it’s nothing like today’s high tech, flashy, realistic racing sims. It uses Flash so it should run on all operating systems.
Drag Racer v3 is an authentic drag racing simulator where you get the chance to test your driving skills against various opponents on the race track. Buy a car, tune it, modify it and race. Collect credits and by tuning parts as well as new cars for your virtual garage. Gear up and become the #1 drag racer in the tournaments.
To use nitro: After buying the kit you must click on the nitro bar to fill it. Then in a race hold the 'N' key to use it.
Limitations:
No online racing, only against the AI.
