Our parent’s house sold, so the weekends have opened back up somewhat. I say “somewhat” because there are always honey-dos, but that still leaves some me-time, so Midlana was taken out for the first time in about six months(!) Everything was fine, until the engine was found to rev limit right at 4,000 rpm, so it was very likely happening by design… (always be suspicious of round numbers). Glancing at the sensor values showed that lambda (air-fuel ratio) was reading “1.oo” (another suspicious round number), which is fine, except that it wasn’t changing. I expected to find that I’d forgotten to reinstall the sensor. I panicked for a second when the sensor was found installed, but then discovered that I’d committed a cardinal sin: installing the sensor but failed to latch the connector. No harm done, but it’s a reminder to not make that a habit!
In other news, Tesla just came out with their Plaid Model S (no kidding). What’s notable about this $140,000 sedan that can carry 4-5 adults is that it has around 1,100 hp. But what’s probably a historic milestone is that you can expect to be barred from many drag strips because it doesn’t have a cage or parachute, items required for 8-second cars, which is what Tesla claims it can achieve.
Drivetrain technology aside, I’m not sure that people spending $140K want something that looks the same as the 10-yr old $60K version. And even more importantly, as impressive as its 1:30 Laguna Seca lap time is, it weighs 4,500 lbs! That’s seriously heavy for a “sports car” of any sort, and all that weight/energy has to be dealt with via the brakes and tires. The brake solution is straightforward: go huge. For the tires though, they’re going to be a very high wear item if anyone takes it to a track day event. That said, tire expense seems to be ignored these days, and I guess if you can afford a $140,000 car, tire cost isn’t a thing. In any case, it seems like we’re very near the point where electric sports cars take over as far as performance goes; all it takes now are lighter batteries to seal the deal. Notice that battery range wasn’t mentioned. The above car has a 500 mile range, so limited range is no longer a reason not to buy one (cost aside of course).
I was looking through the archives and was surprised to see that 10 years ago, Midlana was already complete enough that it was first tuned at the dyno shop. In other news, my brother was set to do the Virginia City Hillclimb again this year but it got cancelled, so he decided instead to get married, hah.
We finally finished cleaning out our parent’s house and it’s now up for sale, so maybe I get back some of my weekend, which has me thinking about what project to do next, but I’m sort of going in circles. As was written earlier, the idea was putting a fiberglass 1930’s coupe body on a late model Corvette. That thinking is confronted with several issues: it’s not anything new or unusual (but, do I care?); I don’t have enough space due to the sheer volume of the parts; I currently want to keep Midlana, which is occupying the build space; because Midlana is being kept, its value isn’t available to fund the next project.
Then there’s wondering whether I should consider going electric, but that means sinking $$$$ (or even $$$$$) into just the drivetrain. There’s a ton of old Priuses (“Pre-eye”?) out there, potentially cheap donors for a play car. The thing is that I don’t want to deal with hybrids due to them having two systems instead of just one—I’d either stay gas or go all-electric. Once it’s finished, it’s essentially a rebodied Prius/Volt/Bolt/Tesla, which, okay, I guess. And then there’s not knowing how much weight can be stripped out of such a thing, A Tesla Model 3 is around 4,000 lbs, so giving it the light shell and tube frame treatment might bring it down to what, 2,500-3,000 lbs? But then it’s essentially an electric Midlana. Since I already have Midlana, I don’t feel very motivated to convert it over because the driveline (motor and battery pack) needs to be designed around from the start. It would be a lot easier for a new Midlana builder to put such a driveline on his build table and go from there. Anyway, for me, I’d like something with more creature comforts, hence me going round in circles, hah.
As I type this, it’s 106° F and is right on schedule, being the first week of September. Before it got really unpleasant this morning, I cleaned out the rat-poop infested workshop at my parent’s house, which finishes the worst part of the job. The house and garage are now about 98% cleaned out, so attention is turning toward making the yard a bit nicer before the house goes up for sale.
It’s a sad but necessary part of life, cleaning out your parent’s home, but so it goes. We’ve had several Zoom meetings with mom, her at the retirement home and us calling from her house. She’s both hard of hearing and has trouble processing sounds even when she does hear them, and between that and the typical laptop speakers, it’s not much of a meeting. She seems happy with the place, but did ask why she was there and when she could come home, and that’s when the feelings of guilt and deceit arise, but there wasn’t any choice in the matter. Anyway, seeing us seems to make her happy, and that’s the whole point.
(It finally dropped below 100° F just before 6PM)
