Pass 5:
Switched lanes. Still a fixed 125 shot coming on at 3,000 rpms. 6 second burnout. Footbrake launch from 1421 rpms. Kinda wish I was at least caring somewhat abotu reaction time, because this would have been a good side-by-side pass against that Malibu. But, like my TnT session 2 weeks ago, I was way more focused on leaving at the proper rpm instead of drilling the perfect .000 reaction time. Anyways, it went 1.47 to the 60 foot and It was spinning a bit but I staked in it and it came out of it. You can see the hood shake as the tires shatter a bit. Still, was happy with the launch, and then 1-2 shift at 6,757 2-3 shift 6492, and finish line 6606 rpms. That slight "flat spot" in the red data-trace is when the tires grabbed through the spin in 1st gear. That run pumped me up, and I was justtt starting to reel him in at the top end.

Pass 6:
8 second burnout, footbrake launch at 2019 1-2 shift at 6740, 2-3 shift at 6503, 3-4 shift 6012, and finish line 5438. You read that right, a 3-4 shift . I was not sure how it was going to go, and maybe it will be better, but I shifted 3-4 wayyy to early so it was a doggg in 4th gear which is a dog anyway in 700r4 transmissions.. even on nitrous. ODDLY, the mph was the same as my other passes where I was topping out at 3rd gear. ??!?!

Pass 7:
6.5 second burnout, and a 1666 rpms footbrake launch. Using another view/page of the datalog (not pictured here) I see what went wrong on this run. One of my safeties (nitrous rich cut-off limit) was activated just a second into 1st gear, so the ecu shut off the nitrous. So my launch was good, but then it was an all-motor pass the rest of the way. Shifter 1-2 at 6523, shifted 2-3 6223, and finish line at 6249. I do physically remember shifting 3-4 during this run too, but for some reason the transmission did not make the shift. Kinda weird, but will have to look into this. It did it the previous run, but maybe it was hot or just damn tired?

Some other videos that were filmed by a drag race friend named Tom who runs at Island . Jerry also took some videos, but I feel super badly that I did not get to film any of his runs.
-note.. I do not know which pass each launch video is from, so I am sorry, I only know the one against that Malibu was pass #5.

Drove the car home late at night. Washed it the next morning and swapped the wheels. Took it to the North Jersey Auto Show today (Sunday) in Paramus. it was raining from the moment I left, and most of the morning. They had a smaller turnout than the usual 400 cars that they get at this show, and I was in the 1980-present class. (they only allow vehicles up to 1996, so I guess the way tos ay it is I was in the 1980-1996 class). Got the class trophy, and drove home in the rain.. with the lakewood 90/10 drag struts, no front sway bar, and maniacs on rt 8p in north jersey.

Going to look into the trans 3-4 shifting situation. My best bet about how to rev out the engine during the last 200 feet of the track is a taller set of tires.. this will have to waif for spring 2022. If anyone has a set of 15" drag wheels with a 27" or 28" tire that I could test fit for a size mockup, please let me know. It would be much appreciated.

On that note, after watching some of Jerry's videos and Tom's videos, I now know that the car does squat. In fact, I was certain that I felt the rear bump-stops hit the axle tube on at least two launches. I mentioned this to the fellas, and I ended up cranking up each reach shock .5 It was probably not enough. I have done a bunch of research and have some 3rd gen buddies who have used the drag-bag air-bags before. It is a budget friendly trick I would like to try so I am probably going to order a set of these. They will also help when I haul the hundreds of pounds of tools to and from each event too. Especially with a taller tire...
