(Applet "DragRacing" would be displayed here
if Java were available.)




This drag racing simulator is pretty straight forward to use.  Just enter the values as they correspond to your car
and press the launch button.  Read on if you need a more descriptive instruction of what each value is.



Instructions:

Transmission :

The Values under the transmission represent the gears the car is currently in and the ratio of that gear.
You can select how many gears you have by entering the ratios in each area. If you leave any values at
0 the program will consider the prior gear to be the total number of gears in the car. In the default setup
you can see that the values of gears in 5th and 6th are zero and so the simulation will simulate a 4 gear
transmission.

Trq Conv :

This value represents the slippage of the Torque Converter or Clutch until full engagement when full torque
of the engine is applied.

Engine :

The drop-down box is the torque curve that represents your engine.  I have only included one engine so far
and here is a graph that represents that curve.



The Redline is set for 5500 for this engine.

The Max HP is the maximum horsepower for your engine. The value is used to scale the rest of the engines
torque curve.

Race Dynamics:

The Shift point value is the one where you would shift your car into a higher gear. You can experiment with
lower values to see what would happen if you "short-shift" your car.  The Shift time is the time it takes you
or the car to make a shift. This value can be 0.1 for fast automatic transmissions with shift kits or slam
shifting a manual to up to 1 second (kind of like shifting a grain truck or semi).

Aero-Dynamics:

Frontal area is the area of your car that the wind hits when you are driving. Most cars will fall between 19
and 22 square feet.  Coeff. Drag is the Coefficient of Drag that your car exhibits. This is how well the air
moves around your car without causing drag on it. Most cars will fall between 0.30 and 0.35 with some
supercars being around 0.28.

Misc.:

Final Ratio is the final drive ratio between your transmission and the axles on your wheels. This can be
anywhere from 2.73, or even less, to 5.56 or higher.  Most cars will fall around 3.23 to 3.93 depending
if an over-drive gear is present.  Wheel Radius is the distance, in inches, from the center of your wheel
to the outside of your tires. It's range varies greatly with all the different wheel setups available today.
Car Weight is the curb weight in pounds of your car with driver.  So if your curb weight is 3000 you would
enter 3000 + your own weight in pounds.

Footnotes:

I hope you enjoy using this program as is and will be adding more features to it as time permits. It took me
around a week just to learn java and then another to make this program.  I want to thank everyone that has
supported this site by visiting and by using the adlinks. Kevin
