Select your favorite vehicle body and head to the engine shop. Choose between Stock, Bracket, Alcohol Injected and Blown engines. Tune your engine for maximum horsepower and torque with the help of the built in dyno. Finish your ride in the paint shop choosing your favorite color and graphics.
Arrows = throttle and reverse, Space = brakes, W = shift, Q = parachute.
Go directly to the Test and Tune, Bracket, Outlaw Heads Up or Blocked Off Street Racing classes and test your vehicle and driving skill. Choose your lane, set the delay box and pull into the water to warm up your tires. If your good enough, perform a across the line burnout for maximum tire heat.
