Using Your Car’s Controller Area Network (CAN) I want to preface this article by saying that I am NOT a Controller Area Network (CAN) or CAN Bus guru. But knowing at least some of the aspects of CAN has become very important when it comes to getting data off of cars and I have spent […]
Braking Techniques to Help You Improve Your Speed Who Needs Brakes? Well, the answer to that question is, everyone! Last month I wrote about different ways to analyze throttle information. This month I’m going to go over some different ways to analyze braking information, or more importantly, slowing information. Obviously applying the brakes slows the […]
I want to Increase My Speed: Why Am I Driving Slower? In terms of how to drive faster, grip is important. As we all know, the grip level of tracks changes all the time. Sometimes it gets better after more and more rubber is laid down over the race weekend. But the grip level of […]
The Importance of Throttle Application & Throttle Velocity In the graph, there are four traces: Speed, Throttle (Gas Pedal Position), Throttle Velocity, and Delta Time (lap delta). The blue is generated by a professional race driver; the red by an amateur. The car and track are the same (a left-hand corner quickly followed by a […]
Why Racecar Brakes are Difficult to Master I don’t know about everyone else reading this, but when I went through my first racing school, there was a lot of focus on race car braking much later than I thought was possible. This is because race cars brake really well and with only street driving under […]
Racing Corners and Why They Should be a Priority In order to get the fastest lap time, you need to figure out what racing corners are more important than others. This is especially true if one corner directly leads into another corner. The SCCA Runoffs were held last fall at Virginia International Raceway (VIR) and […]
Driving Fast: Is Coasting Bad? I have heard many times that the driver should either be on the throttle or the brake and they should never be coasting (no throttle and no brake). But is coasting always bad? After looking at pro race car driver data or simply data of really quick drivers, I have […]
Speed is in mph and lateral acceleration is in g’s. Multiplying the speed (mph) by 1.46667 gets the speed in ft/s and multiplying the lateral g’s by 32.17405 gets the g forces in ft/s2. The radius of the corner then ends up being in ft. It is amazing how accurate this formula can be. In Exhibit 1 I used Google Earth to look at turn one at VIR and I drew a circle that has a radius of 122 ft.
