Picture slide show
Last Friday night someone took some great launch pictures of my car and finally posted them online. This is from my first pass of the night. About 90 minutes later when I made my second pass, I almost lost the car before the 1/8 mile and had to lift to keep the car from going into the wall.

Here's the link to many of the cars that attended. I'm not sure exactly how far the tree is away from the start line but the front end is back on the ground as I pass the tree.

Re: Picture slide show
Video would be so much better but I did manage to gain a little information from the pictures. I went into my browser cache after viewing the pictures to capture the large ones. I can still only blow them up just so much before losing quality.
I can see a good wrinkle in the tire but it's not perfect. The wrinkle should be a little more forward so I probably need a little more air. Those only had 7 psi in the tires. The rim isn't being driven into the ground so I'm still not hitting the tires hard enough either.
I also see the MT on the tire when it's at rest then it's over 3/4 of the way around the tire just as I'm pulling the front wheels. You can then see it rotating forward in the next few pictures. There must still be at least a 1/2 turn of tire spin before it hooks up.
My 4-link IC is just below the neutral line and I can't see the back end of the car squatting or rising as it launches. If it is, I can't see it. I may move the IC forward a little bit more to get more squat.
Estimating length by car wheelbase and the distance on the dividing cracks in the concrete, I can estimate the front tires come back down roughly 30' from the start line. There's 2 pictures in a row that show the front end at the same height. With the front suspension fully extended, the wheels are still about a foot off the ground. I don't even have a jack that could lift the front end that high
No wonder everyone comes up to me after a run and say they love the car. I guess I burned a few eyes on that run also. There must have been about 100 people along that side of the burnout box. Someone posted in another forum that my alcohol fumes were so bad that eyes were watering. The car was running pig rich but was making good MPH.

Re: Picture slide show
I was given this picture last Friday and finally got it scanned into my computer. Good burnout shot from the top of the tower. A black car on a black surface sure is hard to photograph. Good thing I have the flames.
