I'll bring an extra umbrella if I can find one. See if you can find one. Sean, see if you can bring one too. Any bit of break from the sun is going to be priceless tomorrow in the 100+ degree weather.

I put one in the car already (it's black though, but better than nothing). I'm freezing some drinks too.

What a hot fun day!

I got to use the two step each run due to the drag launch start. I'll check the data logs and see what my 60' was

Oh man yeah it was hot hot hot. but fortunately, I had my own portable shade with me which worked out very well. No heat stroke or sun burn so it was a good day.

I took off from the line normal on every run except for my last run - number 8 - in which case I launched it with a vengeance and got my best time of the day. Nah, I didn't win like I was hoping for, but I did get a pretty good time. 60.6 something. I'm happy with it all things considered.

Launching off the start really does make a difference but I just don't do it every run - just on special occasions like maybe the last run - because I know my stock clutch has a limited lifespan and I want to try to make it last.

So lets see... when is the next event???

I only got one reasonable 60' time with my low resolution GPS logging... looks like it was ~1.8. Pretty good That was the run I had someone's girlfriend riding with me. Good run to do it I guess!

Hmm... comparing my fastest clean run to the last run which felt ok, but was 1 second slower... going up to the 1 cone pivot I was 4mph SLOWER on my faster run through the short straight before the pivot.

So here's the sequence, left hander, 2 cone pivot, 1 cone pivot, uturn

So here's the sequence F=Faster, S=Slower, mph(lateral g):
At the exit of the 2 cone pivot, F=24.3(.59g), S=26.2 (.65g)
1/2 way between the 2 cone and 1 cone, F=31.9, S=35.0
apex: F: 20.5 (.26g), S: 20.6(.52g) <-- more g = more slide = more fighting the car if the gps plot is accurate, I didn't swing out here, but took the pivot tightly
corner exit: F: 21.7, S: 22.5
uturn entrance: F: 29(.07g) S: 30(.49g)
mid uturn: F: 31.9 S:31.3
exit uturn: F 38.8(.74g) S: 35.4(.66g) <-- more g here = I was on the gas way earlier. MPH says it too.

Total time?
F: 11.9s
S: 12.3s

.4 right there and I still feel that I jacked it up....

I t was a very technical and challenging course. These turns are not typical which is why I think they gave us so much trouble. I never really felt like I did it perfect on any run either. Sometimes I didn't shift when I should have, and other times I shifted when I should have left it alone. Then there's line - should you be in tight and slow around the pivot or wide and fast?

I think what your data is really saying is that it's not how fast you went in or out, but really which line you take that makes the fastest lap. The speed is the result of the line. In this case I think the answer (as we well know) is a tight line. There's only one way to get that tight line and that's to slow down. Going faster only forces you to take a wider line whether you want to or not. When that happens not only do you have to go further, which takes longer, but you're also in the wrong spot for the next gate after the pivot resulting in more lost time to get back where you need to be.

That's just how I see it.

full throttle - hard braking - full throttle- hard braking / turning - full throttle - pivot!- hard braking - full throttle lol etc.

Yeah... maybe I should tow a shifter cart along just in case there's another setup like that. It was not fun to drive in a sedan. But I guess it was a good learning experience.

Jeremy's car finally looks like it's not going to flip over


Maybe this is the run I DNF'ed. Maybe he's telling me to turn around?

Sorry Chris, no pictures of your car that I can find

Thanks for posting those. And yes.. with the new springs the car actually feel like it should have felt from the very beginning. No more wallowing and leaning way over. No more slopping around when trying to turn.. just nice and responsive and relatively flat.

I think with a little more front camber and some sway bars to keep it flat, I just might have something...
