Well, welcome again in our pursuit of happiness… oops, sorry, pursuit for best lap times, which is motorsport’s joy factor and the way of measuring happiness. Remember that in the last two blog posts we’ve found the proper way around turns 5 to 8 for our driver on Lucas Guerrero track during the Rotax Grand Finals 2014. Unfortunately something went wrong in the second half of lap 7 in session 3 and we should now find out what have happened that caused the loss of those 2 tenths gained before that section.
How should you find such a weak spot within all the numbers and data?! Well, that’s easy with RaceCloud, since we have already thought about making it simpler, easier and faster for anyone to get “into” the in-depth analysis and to do so we made it visual! See the blue and orange lines over the racing line? You’ve already guessing what they are, right? It’s so much easier to understand what’s happening at every centimeter of the driving line with such a visualization of the lateral G-Forces and the Steering Wheel Angle. The pieces of the puzzle are finally getting on their places one by one and we start noticing a lot of details.
And this is how the “something wrong” went out on focus! Something is really wrong with Steering Wheel Angle and G-Force graph in turn 10, right? What we see is that a huge drop in the G-Forces is generated, combined with “opposite lock” with the steering, done by the driver in order to compensate the grip loss and get everything back under control. This however, as everyone in motorsport is aware, is a time killer and despite the higher speed it immediately started “eating” what was gained in the last few turns. Removing the other lap from the comparison clearly shows what have happened and that it was the first reason for losing time.
So the mystery is solved and RaceCloud once again showed us, that even being as close as possible in the matter of lap times, two laps can be a lot different to each other and we can learn a lot from them, being able to understand what the data is trying to tell us!
Follow us for more, since we’re impatient to help you easily understand what’s happening at every centimeter of the track!
This week we continue chasing the clock and it is now time to unveil the mystery that appeared in our previous post. Following the Time VS Time graph we discovered that our driver did some magic in the second sector gaining a lot of advantage in his second best lap.
Let’s examine the Speed graph and find out if it’ll help us determine what happened. What the blue line is showing you is that the driver is keeping higher speed through turn 6, resulting in higher speed before turn 7. A later turn-in for turn 7 on the other side allows earlier acceleration and thus – higher speed in the next section despite the little lower apex speed.
How do we know about the later turn-in? Well, RaceCloud is automatically detecting the braking and turn-in points and displaying them for easier and faster analysis. According the World Champion Mikko Laine, that’s the best feature that we have created so far and he also says that “It’s really useful for all the drivers including rookies and pros“.
If you take a closer look at this section and the points over the racing line you’ll see that in the “blue” lap the driver initiated the braking and started turning at one and the same point, while on the other lap the points are different and the turn-in is earlier. A turn-in point in the middle of turn 5 in the red lap on the other side suggests a possible reason for the lower speed through turn 6, mentioned above. The later braking and more inside racing line caused the driver to work harder and struggle for grip and speed into the next turn and all this resulted in time and speed loss through the whole next section which is faster and thus more important for taking advantage.
In the final section of the track, the “red” lap is “back in the game” carrying more speed into turns 15 and 16 and that helps it to finally make it with a negligible advantage of 0.03 sec. But what caused the loss of 2 tenths of a second in just a few turns? Keep following us so we can find the secret together, next time on RaceCloud Blog.
In motorsports time is precious and comparing times is the way winners are determined! And let’s be honest – no one has found the “perfect lap” yet! Some are faster in the more technical sections on track, others in the faster turns, some are counting on a technical advantage to get with a tenth ahead of the competition. Have you ever wondered how to define the weakest sections of your driving or kart’s behavior? Well, this is the starting point to get fast lap times and this is why RaceCloud is emphasizing even the smallest detail in order to help you easily and effectively improve your driving and kart’s setup.
So, the time vs time graph in RaceCloud’s analysis screen is the fastest and easiest way to detect where you’re losing or gaining time.
Picking a referent lap as a starting point and with another one for comparison you’ll be able to define if you can improve even your fastest lap of the day and which is the section that needs adjustment.
Fox example your best lap may not include all the best sector times achieved, so you might pick it as a reference lap and compare it with another lap, in which one of the sectors have been faster, see which one this is and find the exact spot on track that it became better, thus, finding the details causing such effect.
What you should do? All we have done is to select the two best laps of our driver on the Rotax Grand Finals 2014 and get them into Time VS Time comparison and find the obvious – as simple as that! What is the obvious? After the apex of turn 7 in the fastest lap of session 3 our driver is gradually gaining time (the blue line) up to almost 2 tenths of a second (until turn 10) and it could have been by far the fastest of all his laps on this track during the weekend if he didn’t lose this advantage after turn 14.
What did happen between turn 7 and 14? Well, keep on following us and we’ll solve the mystery!
