Wow! T.J. amazing progress, I just read from page 12 (where I had last been sorry, been busy for a while)
Sorry about the foot & loss of the event/lap record, you'll get 'em next year!

I'm not as bad as I used to be with wheels, because now I consider how they perform as much as how good they look. So many wheels I like are heavy as hell, so I have to reluctantly pass- '91 318iS - NASA TT5

Not too much to report as we wrap up the 2020 season. Overall it was a success, despite some setbacks. My foot is mostly back to normal. It took longer than I expected. I am glad I sat out the FL season finale at Sebring. About a month later, a group of friends and I trekked up to Road Atlanta for the SE Region's season finale, Santa's Toy Run at the beginning of December. It was my first time at Road Atlanta, and it is a hell of a track! Totally different than anything we have in Florida. It was a lot of fun, and my car performed admirably.
Leading up to the event, I did only a tiny bit of work on the car. The car stayed on the trailer after bring it home from corner balancing when I cut my foot. All I really did was some more weather stripping and taping of the front end. Trying to 1) make sure as much air as possible is going through the radiator, and in turn, the hood vent and 2) trying to get any small aero improvements I can within NASA's TT rulebook and given the E30's slab front end.
I did weather stripping around the grills and headlights, similar in style to the E30 M3 EVO style grills.
It took some cutting and modification, but I put headlight backing covers back in on both side's of the car. Then I taped up the gaps around the radiator again. I've done this before, but sometimes get lazy after removing and reinstalling the radiator. I hadn't had it taped off all year.
3 of us caravan'd up from South Florida, and we met 3 more friends at the track, so we had a great group to pit with. We loaded up earlier that week so we could leave early on Friday morning. It was a pretty uneventful drive, besides lots of rain and traffic in the Atlanta area. It was Friday rush-hour after all. We got to the track around 6pm and set up for the morning.
Unfortunately my friend Matt spun out exiting turn 3 in the first session and he tapped the wall. The damage wasn't too bad. He was able to drive the rest of the weekend.

My car only had minor issues all weekend, such as some loose bolts in my IRP shifter and some tire rubbing in the rear that I had never experienced at another track. At the bottom of the esses, my passenger's side rear tire was getting cut on compression by the foremost part of the rear fender, that was not rolled enough. I couldn't get anything to work to roll the lip back under except hitting it with a hammer. Besides chipping the paint, no ill effects. No more rubbing after that.
On Saturday evening I noticed of my X5's tires had a leak. Luckily we had a patch kit and were able to repair it in the garage of the Airbnb. 315/35-20!
Sunday morning was especially cold. The cars all had ice on them. It didn't get "warm" until around 10, 2nd and 3rd run of the day were especially nice and beautiful.
On Saturday, I was able to pull off a win in TT5 on the last lap of the last session. Even then, I only won by less than 2 tenths of second. On Sunday, on a good nights sleep, I went a lot faster than on Saturday. I improved over 3 seconds on Sunday, and won by a large margin.
Overall the weekend was a success and well worth the drive. I spent a few extra days in the area, and headed back very early on the Wednesday morning following the race.
That does it for 2020. Photos from Road Atlanta to follow.

NICE!
Bummer about your buddies E36. At least it wasn't too bad.
Nasa Time trial looks interesting, something I may try.
What was your best around RA?
Have you tried taping up some squiggly's to see where the air is going? Or adding a gurney flap on the front of the hood vent?
Might be able to run a lower temp Tstat and tape up front front end more if you're efficiently getting air through the radiator.

On 30+ heat cycle Hoosiers (aka: dead), I got down to a 1:43.4 on Sunday. Being a smaller track, I had to deal with traffic more than I'm used to. I think I'd get down to the very low 1:40 range with more experience at the track.
I definitely want to learn more about what the hood vent is (or isn't) doing. I'll run some experiments and put a GoPro on the hood. There is a raised section at the leading edge of the vent, but a straight vertical wicker bill might help further. For my class, there are rules for the height of the leading edge Gurney on any vent, so I'd have to keep that in mind.
I also want to try the different types of E30 grills. I currently have the Euro with smaller/less slat openings. Some of the US grills had larger/more openings. The goal would be to get as much air through the radiator and out the vent, rather than collecting on the front end, or going through any of the other nooks and crannies on the front of the car. Not for cooling, since I don't have any issues with that, but for any aero improvement I can get.
An idea and dream I've had for a while is to try and duct/route/force more of the air exiting the radiator through the vent, but with such limited space, I don't know what would be possible there. Especially since I have an electric fan mounted on the back of the radiator. That would make a K24 swap even more attractive to me, for smaller packaging in the engine bay.- '91 318iS - NASA TT5
