Why do your recorded figures for drag-racing the [insert car here] differ from mine?

Like everything else in the world, performance testing needs to be taken with a grain of salt. The same car on the same day with the same driver will vary from run to run, much less with different cars, days, or drivers. Even procedures and venues differ: what if you use a shallow stage versus a deep stage? What if the venue you're using is super-sticky and flat, or rippled and slick? What if it's hot, or higher altitude, or really humid? There are many factors that can affect performance measurements.

Every attempt has been made to make the measurements as standard and comparable as possible. The G-Tech performance meter is very accurate out of the box (see the review by Car and Driver), and we've been using it for a while. We also have a spreadsheet which attempts to correct all results to match SAE J1349 (June 1990) standards. Like everything else, this isn't perfect and shouldn't be regarded as a natural law.

I can't play the videos on the site. What program/codec do I need?

Most of the videos are encoded with Windows Media 9 codecs. You can download the codecs for WMP9+ (or for WMP7+) and you should be able to play them. We also recommend using Media Player Classic if you have any problems.
