Took some video of an open track day this last Friday. There are three of my most consistent, fastest laps to date, all in the 1:55s. I ran one 1:55 the last time I went out with consistent 1:57s after I put some old radials I had laying around on the car from a couple years back, so I got the most out of them the last track day. This time they held on for about 4 laps in the morning, and then just got greasier and greasier as the track and the day warmed up.
So I have three clean laps back to back at the beginning, a slightly slower overall time lap as the fourth but there was some neat traffic so I left it in and it was my fastest shot down the bobsled to hell and sliding back up the hill, then some footage of traffic to see some cars, general bloopers and random chaos. And then I realized upon editing that I left the camera on when I finished, so I got a bunch of footage of various folks coming up and asking questions, talking about the car when they thought I couldn't hear which is always funny, but I threw in one snippet of a corner worker that worked down in that area I would go sliding through and the open wheeler spins. The springs are getting stiff enough that I know I have to get the right camber set on the car, some new radials, then monkey with tire pressures. I suspect that I am in the "1/2 psi makes a big difference" spring rate range. http://www.youtube.com/watch?v=lg8SkOZVLBs |

Terry - the full course you see me running there is 2.55 miles. It is a pretty technical course actually, so pretty hard to get the car sorted for it - there are two tight turns as you can tell, then some mid speed ones, and a couple fast ones, so finding the right mix of suspension settings to get the best of all worlds has been some work. I have been keeping track of the suspension frequency as I try different springs and right now it appears if the frequency of the front is around 94-96% of the rear, the car is pretty neutral overall with easy on-throttle oversteer to whip out of the slow turns.
Randal - would love to do a hill climb, if they pave Pike's Peak all the way to the top I will definitely run it, but Oregon would be a stretch for me to drive. |
