00:00 - Today we're going to be doing a worked example based off the RaceCraft 6 step data analysis process.
00:06 The car we're going to be doing this on is our own GT86 shop car.
00:10 So the car itself is a GT86 that's mildly modified, it's got a turbocharger fitted to the engine and an intercooler.
00:19 It's got some suspension components like some adjustable control arms, uprated and adjustable anti roll bars, got some MCA coilovers, it's also got 18 inch wheels and Michelin slicks so while it's only lightly modified, the performance for a circuit car is definitely quite a lot better than it would have been from factory.
00:38 The logging equipment we've got fitted on this car is a Racelogic VBOX.
00:41 The VBOX is something that's really popular in the motorsport industry, it's something that you not only see fitted as a standalone logger but also as a supplementary logger for some high end cars.
00:53 So what I mean by that is for example in some high end GT and prototype racing, you'll often have the main logger fitted to the car that'll be built into the main wiring loom and you'll also have a VBOX fitted supplementary to that and the reason is that quite often things like amateur drivers find it really easy to use, it's not a big steep learning curve to figure out how to use it so it can be a really effective training tool, there's not a lot of overhead as we'll see going through today's worked example when it comes to setting these up and also looking at the data itself.
01:23 The data we'll actually be going through and using for the worked example was gathered from a recent track day we did with this car so we've got one of our normal amateur drivers that normally drives this car and also we got in touch with the track and got them to give us a pro driver for the day to help us set a reference lap.
01:38 Now that's something we've talked about quite a lot in the data analysis course itself.
01:41 Obviously, if we've got a professional that is able to exploit quite a lot of the performance of the car, that gives us a really good benchmark.
01:49 At that track day we did quite a few runs, most of that was just with the amateur getting back up to speed, it'd been a while since they'd been in the car so it was really just a case of getting them comfortable in the car, making sure everything was working in the car, making sure we had no mechanical issues and everything in the data logging system was working properly.
02:06 Then later in the day once the amateur was comfortable and we were happy that they'd set a representative lap time we got the professional in the car.
02:12 Now the professional actually only did one run to set the reference lap that we're using today, I think they only did about 5 or 6 laps in the car and really quickly they were up to speed and were able to set a significantly faster lap time than what our amateur was able to set in the car.
02:27 Which is exactly what we want because that gives us a great reference for training the amateur using the data.
