Off to stuff my face, Happy Thanksgiving

And a pleasant Thursday to the rest of the world. I’m not going to bore you with a recitation of traditional Thanksgiving dishes I hope to consume, just assume if you know of one that is generic across the US I will probably consume some today, plus some Texas-specific dishes like Jalapeño corn casserole. This is kind of a group dinner with one person coordinating the menu and sides, someone else cooking the turkeys and other meats (smoked brisket is a popular Texas Thanksgiving entré) and the rest of us bringing the assigned sides.

We finished the Egyptian Run and brought back the Pyrite Cube of Great Power and up next is the barbecue and followed by Glorious Training! (trope stolen from dozens of anime and specifically Sparkling Generation Valkyrie Yuuki a goofy web comic that hasn’t updated in months but the creator assures me will update “soon”). I really need to upgrade my blades and pistols skills and also develop the Observe skill. I forgot to include that at character creation, so I will spend Karma points and nuyen to get it now. The group decided to go out for dinner and bought me some too, which was nice of them because I think I’m down to about $15 until the end of the month in my checking account, and while we have food at the house last night was the first calamari I’ve had in years. Of the group I had the cheapest dinner which gives you and idea of what kind of dinner they bought, everyone else had a pound of snow crab plus something else, and I got some of that too because who really eats that much crab in one sitting unless they have been starving all day. I should also mention for the sake of full disclosure that I had calamari since the last time I had crab of any type, so I was out of practice at extracting the meat from the shell.

So to recap, Happy Thanksgiving to my US readers, happy Thursday to everyone else, and all you still hanging on from when this was a bicycle safety blog, this is a good day for a ride.🚴‍♂️ 👍🏼

I found another problem

I was doing a little SWAG on the Sprint-T and tires and I came up against another problem. I can only hook up so much HP no matter how big I get the tires, because of weight. Traction is a function of weight and tires, and there is a hard limit to traction with a car as light as the Sprint-T trying to use UTQG 200 treadwear tires. I can get a little more power to the ground with sticky race rubber, but depending on the weight of the car I’m looking at 300 to 500 HP without boiling the tread off the tire before getting the pedal to the metal. More than that and I’m never getting my foot to the floor.

What I’m looking at is with the Subie engine and the T5 transmission I can stop cranking up the boost around 300 WHP, with the Pentastar V6 and the 8 speed transmission I can stop trying for more than 375-400 WHP because that transmission just weighs that much, the LS3 and the 4l70 I can pretty much leave in stock tune, and the LS7 I will need to put a block of wood under the gas pedal to keep rear tires on the car unless I’m running the softer compound of the race slicks I have available. Street tires will require really feathering the gas to maintain traction with just the stock 505 HP tune.

Now these are just what they used to call “back of the envelope” calculations but they are the best I can do with the data I can get, and the low precision of the data. Seriously I’m looking at ±0.1 G precision on a 0.8G predicted grip for the 200 wear tires, or 0.7 to 0.9G and a huge difference in performance between those numbers, so lets say we are talking about the LS7/3 we are looking at maybe 400-430 WHP on the low end, just shy of 500 at the high end. And as far off as I was on the unsprung weight at the front end I’m not putting much faith on these numbers either. But if the data is correct and I used to correct formulas, If I’m running an LS7 then I don’t need to use the dyno for anything more than fine tuning for gas mileage and verifying the stock tune is working correctly. Pretty much the same for the LS3 except I have more room on the other side of the equation, I could get away with maybe the 480 HP tune, but not the 525 HP tune.

And I didn’t get much sleep last night, and I’m starting to get a headache, so bedtime.
