We really used it to change the CoG height of the car, as part of a series of tests to establish the importance of CoG height and longitudinal location in different scenarios (slaloms, constant radius corners etc). We also used a 6mm thick steel undertray to lower CG, and a 20kg bucket of lead either on the front bulkhead or hanging off the diff to shift weight forward and back. |

This reminds me of a discussion we had a few weeks ago about how high our CoG would need to be for the car to wheeley in the accel. event.
I can't remember the exact figure, it was something like 5kg on the end of an 18ft pole :s Disappointingly high Simon ---------------------------------------- Team Principal 2009-2010 Brunel Racing |

I'm not going to share the intimate details of what we discovered, but I will say that CoG height was nowhere near as important as I thought it would be, which makes sense if you look at the load sensitivity of typical FSAE tyres (got TTC data?). Maybe this is why our 2009 car had only a 1m track width...

I doubt very few people outside of their team have any comprehension of the sheer amount of data Auckland collect during testing and indeed competition (and not just on their car  )On that topic: Malcolm, can you please forward me all your test reports for the last few years I would like to try and apply your very specific test data to my own car. hah. --------------------------- 2006 QUT Motorsport - Manufacturing Manager 2007 QUT Motorsport - Controversy Raiser 2008 University of Waterloo Formula Motorsports - Exchange Student / Electrical Team Manager 2009 The University of Adelaide Motorsport Team - Consultant 2010 The University of Adelaide Motorsport Team - Project Manager |

You make us sound so much more awesome and organised than we actually are, Kirby. You are right, though: we do gather data on other teams cars as well as our own. Some other teams may have noticed our "Timing Team" up on the hill, recording all of the lap times from endurance. "He who dies with the most toys wins" |

I was thinking that too, but I didn't want to make people realise that we were not awesome, damn you Paul! |

I was allowed to rummage through your "filing cabinet" at comp last year...I was pretty impressed. Way more than I 'see' other teams doing. --------------------------- 2006 QUT Motorsport - Manufacturing Manager 2007 QUT Motorsport - Controversy Raiser 2008 University of Waterloo Formula Motorsports - Exchange Student / Electrical Team Manager 2009 The University of Adelaide Motorsport Team - Consultant 2010 The University of Adelaide Motorsport Team - Project Manager |
