Step Three - Throttle

Studying the throttle trace held a bit of a surprise. On first inspection you can see that the red line which is the slower of the two, gets onto the throttle earlier. The quicker green line gets on the throttle slightly later but reaches maximum slightly earlier. Now, so they say – the guy who gets on the throttle earlier is quicker..... not wholly true, which is confirmed in the throttle position article

This is because on the slower lap the driver was anxious to get back on the throttle early because he was aware that he had lost some cornering speed at the apex, and in trying to get it back he pushes a bit too hard and the rear tyres give up a little. You can see on the slip trace that the red line is higher than the green, revealing a slight amount of wheel-spin. The feeling of slight traction loss caused our driver to hesitate a bit on throttle application which cost a bit more time.

We've gone through a similar process at every corner at Whilton Mill, and our data has revealed that we should find another half second at least, so we expect our pace to be significantly below the lap record next time out. I'll let you know how it goes!!

If you want to find time easily like this, you can plug in the AiM GPS straight into the Mychron 4 and get started immediately.
