03 CLS-6 (stock) track results!
So I went to the track today hoping to walk out with a 14.5 but it didn't quite happen. I did a total of 5 passes, neither of which had a 60' time better than 2.4xx. They were not spraying VHT and it was quite the piss-off. I was launching at around 3K rpm, easing into the throttle to try to get as much traction as possible. I finally got what felt like a 'good' launch on my 5th run, and I didn't spin at all in 2nd gear but only nailed a 14.9 @ 97 on that run. Anyway, below are the results:
(63 degree weather, and I believe altitude is 0)
1st run: 14.984 @ 96.272mph (32psi front tires)
2nd run: 14.894 @ 96.321mph (32psi front tires) <-- best run
3rd run: 15.008 @ 96.343mph (22psi front tires)
4th run: 15.184 @ 94.687 (20psi / tried to trap in 3rd but bounced off limiter of course)
5th run: 14.902 @ 97.048 (20psi front tires) <-- best mph
Here's the best timeslip:
Well it was fun, yet frustrating because of no traction. I know this is a mid 14 second car stock and I will go back to the track on a good day when they spray the VHT. Was a shitty day for anyone running street tires. An SRT-4 could barely break out of high 14s as well.
Pics from this track day are coming up soon!

did you lower your front tire pressure?

I believe I predicted 14.8 @ 97 MPH. ![Whistle](https://acurazine.com/forums/images/smilies/whistle.gif)

Hey man good job. For stock tires those are the times and 60' times i'd expect to see from a 6MT. The 6MT really pulls hard on the top of 3rd and in 4th it will blow by even a modded (I/H/E) automatic CL-S in the top of 3rd.
FYI a stock automatic CL-S will only trap 93-94 MPH although the torque converter will help the launch and is capable of running identical ETs as to what you posted today. Keep trying and you'll get better. Great job

LOL, thanks mrsteve!
Your prediction was quite accurate. Perhaps I will get some better times if I go when they spray VHT... though the 63 degree weather today is hard to beat. Whatever I lose on the 60' I probably gain in top end.
I will have some pics from the track for you guys once my 'photographer' send them to me!

VHT might actually hurt you if it is fresh. Wheel hop is a bitch in the 6-speed and an ultra sticky surface will lead to wheel hop. It is still early in the season. By the fall you'll be running great times because there will be so much rubber on the track. My best short times always came from runs made after August.

TQ > MPG
Thats EXACTLY what I ran in my first trip. It takes some patience, practice, and a good driver to pull mid 14's on stock tires. I found it better to have *some* tire spin than to bog it, because the J32 is pretty tq'less off idle, so it cant recover from a botched launch. I think mybest 60' on stock tires was 2.306, and that even had a hint of wheelhop on the 1-2 shift.
Your mph is in line with what it should run, so 14.5's should be attainable with a better 60'.
First time at the track for me: https://acurazine.com/forums/showthr...ighlight=track

What I normally do is use my fingers to pull straight down (1-2, 3-4, 5-6) and the heel of my hand to go up for 2-3. For the 4-5 shift I hold the top of the knob and guide it right. I have only had a problem with sometimes catching 5th when I wanted 3rd. Not a fatal problem, but kind of annoying. Bad habit that comes from my 4 speed days - guiding over to the right.
When I am on the highway, I find going down 3 gears tricky (6-3)... and I find that I do not get the acceleration I sometimes need just going to 4th. At 60MPH I bump up from 6th allowing the stick to centre and then push up with the hell of my hand, catching 3rd at around 5K rpm. The only problem with this is that it is a bit slow... if you go too quick you simply catch 5th. Any other suggested techniques?

Gored, the proper way to shift is much more easily explained with illustrations. With that said, here's a few quick notes:
1st-to-2nd: grab the top of the shifter with your thumb, and the right of the shifter with you palm. Pull straight down, with a little bit of pressure towards the left.
2nd-to-3rd: grab the top of the shifter using the palm of your hand, and push it straight up. It will automatically go into 3rd.
3rd-to-4th: this is the one that causes the most mechanical over-rev's and engine failures. You can grab the shifter with the palm of your hand, but make sure you pull straight down. Or, if you really want to make sure you don't miss the shift, grab left side of the shifter with your palm, with your thumb pointing down. Pull straight down. This will ensure you don't accidently shift into 2nd gear.
4th-to-5th: grab the right side of the shifter with your palm, and wrap your thumb around it. Push up and to the right.
5th-to-6th: use the same technique as 3rd-to-4th. Palm on left side of shifter, thumb pointing down - pull straight down.
This is probably hard to make sense of just by reading it, but try it out in your car, you'll see that it feels quite natural!

Downshfiting by accident into 2nd gear will launch the engine in the 15,000rpm range (or something astronomical like that) and that's when Mr. Piston meets Mrs. Valve and things shack up from there!
