01 - Circuit Tools The Art of Going Faster


Circuit Tools software is a data-analysis package designed for Racelogic GPS data-loggers, including VBOX, Video VBOX, VBOX Sport, DriftBox and PerformanceBox. The software is designed to automate many tasks and quickly present a driver with the crucial information required to improve lap-times. The software is designed by racing drivers, for racing drivers, with none of the complexity normally associated with analysis software which is often aimed at experienced race engineers. The software can work with or without video, but this manual will assume you are using video as this is the most effective way of analysing circuit performance.
For an quick software overview, please look at the Quick Start Guide.

The Art of Going Faster

Circuit Tools and Video VBOX exist to help you to go faster, so what is the best way to go about this? By far the most effective way is to get someone quicker to drive your car for a few laps and then compare data. There are a number of professional driver coaches who already use Video VBOX who would be more than happy to help out.
There is an list of recommended coaches here: http://www.vboxmotorsport.co.uk/index.php/en/aoi-race-coaching


Once you have the data of the faster driver, load both files into the software using the F3 key. Then examine the Delta-T channel (in blue beneath the speed traces) and look for a big change in lap-time. 
When Delta-T increases, time is being lost, and when it decreases, time is being gained. Have a look at the example below which is zoomed into a section of the track where there was a large change in Delta-T, which was worth around 1s in lap time. 
By zooming in to this section (use the mouse to click and drag a zoom box) you can analyse what is happening by comparing the speed traces:
(1) The slower driver (blue trace) brakes earlier and lighter for the corner, this loses 0.15s in the braking zone.
(2) Then the faster driver (red trace) uses more throttle on the exit of the corner and around the following left hander, gaining another 0.25s.
(3) The faster driver brakes later and harder, gaining another 0.5s.
By making these simple changes, the slower driver could have gained 0.9s in these two corners.
The next stage would be to watch the videos side by side in slow motion, to watch the lines taken by each driver. It is often useful to check the position of the car relative to the kerbs on the entry, apex and exit of the corner. Move the video one GPS sample at a time by holding down the ALT key and using the right or left arrow keys.


We have written a comprehensive ebook with tips and tricks on going faster using Video VBOX, it is available for free here: http://www.vboxmotorsport.co.uk/ebook
Good luck!!
