Newbie Stuff - What is a Dyno?
Most any dyno you find will be computerized and capable of a color printout of one or more dyno/torque plots vs. RPM. What this means is that you should get a printout of your car's power/torque output from low RPMs up to redline or fuel cutoff. Keep in mind that by measuring at the wheels you will see between 15% and 17% lower numbers than you might expect due to drivetrain losses. Automatics will typically lose a little more power than manuals as well.
Please keep in mind that few measurement devices are perfect. Though most dynos will be accurate to within .5HP or .1%, this is usually dependent on proper calibration and compensation. Depending on age and condition, your results may vary. Also, different cars behave differently depending on age, condition, and all manner of factors throughout it's lifetime. For instance, if you haven't tuned up in a while you might see as much as a 5HP or more loss.
The plots that follow are of members' cars with various mods. Where possible, the mods and anything that might improve power output are listed. Although you shouldn't expect to be able to duplicate someone's output, this should be useful as a rough guide as to what mods provide what power. As mentioned above, individual vehicles may vary as well as the numbers obtained from different dynos.
