Big racing weekend

There are a bunch of races on the tube this weekend, trucks tonight, Xfinity series tomorrow, and F1, Monster Energy, and Indy Car on Sunday. Indy Car is deciding their champion Sunday, Xfinity series is starting their playoffs and the trucks are setting their playoff contenders tonight. Racing inspires me when I’m building my TGS2, but I don’t get any direct transfer from their designs. Detail touches sure, but nothing major can transfer because of the vastly different technology in my car and all of those race series. I think the closest is Indy Car or F1 because of the mid-engines, but with the tubular beam front axle and de Dion rear suspension on my car compared to the 4-wheel independent suspension on those cars, and my engine being transverse and their engines being longitudinal, and I have a 4-sp automatic and they have 6 to ? speed manual or semi-automatic transmissions. Like I said, details, details.

I have been following a YouTube series on building an Australian rules Formula Vee and I have to say their rules are a wild combination of ancient suspension geometry and frame, and modern aerodynamics. And the tires are completely different from the spec tires used in the US. Like I said, interesting and something to add to the data bank even when there is no direct transfer to my car. I like to learn as much as possible because you just never know when something you learned is going to come in handy. And that doesn’t just apply to cars. Sioux, that one’s for you.

One of the things I have been thinking about was extending and smoothing the front contours of the body for more room in the cockpit and better aero for freeway fuel economy. I have some options on that, because I can either put a big fuel tank behind the driver, or two smaller tanks on either side of the driver in a more supine driving position for less frontal area. The single tank behind a more upright driver is better for Goodguys autocross and SCCA Solo racing, but the laydown position gets better fuel economy and isn’t a very big handicap for autocross and Solo. Final analysis it depends on personal preference, my personal preference. And I prefer to sit more upright and be able to see my outside front corners, plus the single tank costs a ton le$$ than the two tank setup, because the single tank is a stocked item in several retail sellers, while the dual tanks would be custom job$.

Something else to consider is the adaptability of the cockpit to different drivers. The supine driving position requires lots of changes between drivers unless they are practically identical twins where the more upright position just needs to change the seat insert and maybe the steering wheel when changing drivers. I’m thinking about changing drivers because I want to have a pro driver to get the most out of the car at Goodguys, and I have a friend who’s a decent driver and probably wants to get behind the wheel in competition, too. So I really need a cockpit that is adaptable to different drivers without major disassembly.

It’s ‘Dega baby!

Just finished watching the Xfinity race from Talladega. There were lots of wrecks but not while I was watching. I kept coming back to the aftermaths instead of the actual wrecks. I don’t like wrecks, I hate seeing good race cars torn up, I’m also not very happy about seeing crappy race cars torn up. I mean sure I am less unhappy about crappy cars getting torn up, but at the Xfinity and Monster Energy Cup levels there really are no “crappy” cars, just “less perfect” cars that could run just as fast with a few adjustments. Part of that is rules, part is the teams are just that good.

Watching the Xfinity and Cup Series is part of my inspiration for both the Sprint-T and the Mid-Bucket. Also I watch YouTube videos of Goodguys Autocrosses from recent years and SCCA Solo events that have Modified category cars for when I run slicks. Speaking of slicks, I just can’t find 16 X 12 wheels in my bolt circle at a reasonable price, so that means the 6″ Formula Vee rears on the front on the 4″ wide wheels, and the 12″ wide tires on 10″ wheels on the back.

And now the ARCA cars are about to run (on the tube at least, I don’t know if this is live or tape-delayed) and in about an hour is the IMSA race from COTA outside Austin. So then I start flipping back and forth. And I won’t have the split attention that will let me write and watch 2 races at the same time so I’ll go ahead and end this post.
