PerformanceBox is a GPS based performance meter that allows you to measure G-forces, speed, lap & split times, 0-60, 0-100, braking distance and many more.


The new Predictive Lap Timing function (live comparison to best lap) gives you instant feedback on your driving and helps you to find valuable improvements in your times.

All parameters are logged to an SD memory card ten times per second for later review and comparison.

PerformanceBox contains an integrated antenna, is compact in size and very easy to install. 

Available in three different packages.

display-performance-mode   display-laptiming-mode   display-power-mode

Acceleration: 0-60, 0-100. Displays: time, g-force

Braking: 60-0, 100-0. Displays: time, distance, g-force

Distance: 60’, ¼ mile, ½ mile, 1 mile. Displays: time, trap speed

Live G-Meter: acceleration, deceleration, cornering g-forces, with max-G


Lap Time: Displays: current lap, last lap, best lap

Split Times: Displays: split time or speed at a split point

Virtual Start/Finish/Split Lines: Using GPS, there is no need for an external beacon or transmitter. Split lines can be easily saved and transferred.


Wheel HP Calculation: Enter your vehicle’s weight and run an acceleration to estimate wheel horsepower.

Flywheel HP Calculation: Perform a coast-down test to measure drag, and the PerformanceBox will calculate HP at the flywheel.

Speed: PerformanceBox also works as a highly accurate digital speedometer with compass, a handy feature for street driving.

Accurate GPS speed can be used to calibrate a vehicle's speed readout.


Predictive mode enables you to graphically view your predicted lap time.

Predictive lap timing works by saving your position around a circuit, every second. If the current lap is the fastest so far, then this positional data is saved as a reference.


This screen provides the ability to configure the input channels of a connected Micro Input Module and view the data on each of the input module channels.

A Micro Input Module allows 4 analogue and 1 digital (RPM) inputs.

Analysis Software

Circuit Tools is designed by racing drivers for racing drivers, with none of the complexity normally associated with data analysis software.

Watch the video below to see how easy Circuit Tools is to use:

Circuit Tools works with any VBOX Motorsport product and is free to download.

Huge track database

The software automatically detects the country, circuit and track configuration from a database of almost 500 circuits and uses the start/finish line information to separate the laps contained in your recorded file.

The fastest lap from your latest session is automatically chosen and displayed on the graph window. The video is moved to the start of this lap. You can compare runs from this session, or from previous ones simply by clicking on the relevant lap time shown in the session window.

Lap time difference channel

Time difference or 'Delta-T' is a very useful channel that shows the lap time difference between two different laps.

Performance Tools

This software allows you to analyse your vehicle's performance in a range of acceleration and braking tests.

To use the data logging, simply insert the 64MB SD card (which gives up to 53 hours of logging) and drive. Once you have finished the test, either plug the PerformanceBox into a PC via the USB cable provided, or remove the SD card and place it in a suitable reader.

The data is then read into the Performance Tools software, which is installed from the CD supplied.
