Here's the video, as promised. In the video, I also go into detail about the weight loss, and how it affected performance. Enjoy!
If you're short on time, here's the breakdown:
Weight Loss - 414 lb (187.8 kg)
Trap Speed - 3 mph (4.8 km/h) faster
Elapsed Time - 0.8 sec faster
The old rule of thumb is 0.1 second faster for every 100 lb of weight loss. If that were true, my car only would've been 0.4 second faster. I'm sure there is some situation where the rule of thumb is accurate. But not my situation! The lesson here is: rules of thumb are not gospel.
There's another lesson to be learned. And that is, if you have a slow car (like mine), then just about anything you can do to make it faster will help. Pulling weight out of the car cost me almost nothing (except my time), and made the car almost a second faster in the quarter mile. The low-hanging fruit is easy to pick, and gets results.
I think the next mod will be a differential swap. Last time I was at the salvage yard, there was an X3 with a 3.91:1 diff. That should be fun.[This message has been edited by Blacktree (edited 02-27-2021).]

Did they put the DA on the time slips? I am guessing the air was a bit better this time around

No, they didn't. But weather conditions were similar. Although in the previous drag race, I think it was a little cooler.
Also, in the previous drag race they put more effort into track prep. This time around, it seemed they just wanted to get the cars down the track ASAP.

I had to take some time away from the BMW, to work on another project. But that's done. I made another trip to the salvage yard, looking for more parts. This time around, I picked up a transmission cooler, a power steering cooler, and another instrument cluster.
I replaced the instrument cluster already, because the original one died. The replacement one worked, with one exception: the PRNDL display didn't work. I didn't think to make sure it was from the same year and same transmission, so maybe that's it. This time, I made sure to get one from the same year and transmission. Hopefully this will fix the problem.

There's nothing major going on at the moment. But I was able to address some minor stuff. It feels good to cross things off the to-do list.

Just a quick update: I entered the BMW into a car show! This is not a normal car show. This one is geared toward DIYers. It's called the InterNETional Car Show 2021, an online event hosted by Deboss Garage. Here's a link: https://debossgarage.com/ics2021
And here's a link to my entry:
https://debossgarage.com/ic...-the-basket-case-bmw
Also, here's the video I made for the entry. LMK what you think.
Wish me luck!  [This message has been edited by Blacktree (edited 03-24-2021).]
