This weekend is the Virginia City Hill Climb and me and my brother are about set. My brother’s car had a bit of a hiccup, with a new noise coming from the differential. Turned out that some of the ring gear teeth were cracked, and he was told that’s because this model diff is good to ~350hp, and he’s running 450whp through it. That’s a bit surprising given that the straight axle assembly weighs 150 lbs. Anyway, it’s fixed now, though he’s a bit concerned though about how long it’ll last. I urged him to take it easy, not stressing the gears, and to baby it up the hill, hah.

At the same time, he also had his old torque-sensing gear differential swapped back in, replacing the clutch type. I asked why, given that the general consensus is that clutch differentials consistently yield faster lap times. He said that at a track day event, he lifted a tire under braking—once—and smoked the differential clutches on that side and ruining it, so he’s done with that type.

Speaking of differentials, it reminds me of the many changes that have been made to Midlana since her last track outing: higher compression, better cam, larger turbo, overhead intercooler and ducting, retuned, different transmission gear ratios, different type differential, stickier tires, diffuser, different shock settings and spring rates! A good reason to do a lot of practice runs and take it easy learning what’s effectively a different car.

The weather this weekend looks promising, with temperatures expected to be in the low to mid-70s. Cool enough that we won’t overheat, and warm enough that the tires will probably get up to temperature.

The cars will be towed up Wednesday (a 9-hr tow, ugh), then driven up to Lake Tahoe on Thursday for some sightseeing and picture taking. Friday is more local sightseeing, which is a kind of a big deal around Virginia City, because this is where the Comstock Lode was discovered, the largest silver mining area in the world, at one time at least. Mark Twain ran a newspaper in Virginia City for a few years (with Wikipedia saying that he was challenged to no less than four duals during that time). Friday evening is tech inspection; Saturday is practice, and all of Sunday’s runs are times, with your best being “the one.”

I’m taking both the Sony and GoPro action cams and hope (with a glare toward the GoPro) to get some good video to work with. Editing it down will take a while, but I’ll be posting pictures as they’re taken through my Instagram feed (Midlana1). Don’t expect any updates here until next Monday or Tuesday night.

In other news, the wife said that there’s a big branch from one of our pine trees hanging over (and on) the neighbor’s fence, and she wanted to spend ~$1000 paying someone to trim it. Since she sleeps in, I went out early “unmolested” and cut up the offending branch (and yes, the voice in the head did point out that I may be getting too old to be climbing trees—I paid no attention). Granted, I didn’t trim the entire tree, but I choose to look at it as having just “paid” for a good portion of my upcoming trip. That’s my story and I’m sticking to it.
