Drag Racing

Computer Programs and Electronics to Simulate, Predict and Analyze many aspects of your Drag Racing vehicle and your reaction time.

If you don't turn corners, Performance Trends Drag Racing Programs can help you optimize your vehicle. From 300 ft sand drags, 1/8 and 1/4 mile drags, to the Bonneville Salt Flats, you can see what mods will help your performance. We have 2 versions of our Drag Race Analyzer, both standard and Pro. The 4 Link Calculator and Practice Tree can help you launch better. The Drag Racing Clutch Analyzer can help you adjust and fine tune your Centrifugal Clutch. And if you need a data recorder, our affordable Drag Race DataMite packs lots of features in a small, rugged package, and is even NHRA Accepted for classes which allow data loggers.

DataMite Mini USB Weather Station Our DataMite system that works with Drag Race Analyzer Pro to help figure out Throttle Stop and Dial In predictions based on current weather and wind conditions. This systems works great with bracket racing.

DataMite Mini Weather Station Wind Wizard

Weather Wiz is our Weather Station Software. It allows you simply adjust all those weather related calculations like Density Altitude, Relative Air Density, Dyno Correction Factor and more. It allows you choose the inputs you want to use for putting in barometric pressure, humidity and air temperature. It "talks" to our USB Weather Station for on-the-spot updates of critical data.

Engine Analyzer Pro Enterprise Edition v3.9 Adds several additional features most dealing with Turbos and Superchargers. Head over to the page to see all the addtional options.


All our Engine Analyzer programs will create power curves which will automatically drop into our Drag Race Analyzer programs.  You can also "auto link" them so that every time you make a new Engine Analyzer "run", the ET, 60 ft, MPH, etc are displayed right in the Engine Analyzer program.
