Joey Logano is the 2018 Monster Energy NASCAR Cup Champion

It was a heck of a race with the 4 Chase drivers in the top 10 almost all of the race and top 5 most of the race. It basically came down to the last pit stop, and who had the best setup at the end of the race. When they lined up after the last pit stops I honestly thought Kyle Busch was going to win, but they missed the setup, and Martin Truex took the lead, then after a few laps Logano passed for the lead, Harvick poked his nose in and Busch faded to 6th but recovered so that the Final Four finished 1-4. I was really pulling for Truex to win the championship in the last Cup race for the Furniture Row Racing team but he couldn’t catch Logano and wound up 2nd.

And I’m still recovering, the flap is still alive and has some sensation, and typing is still heck with the bandaid over my fingertip. I have been thinking that just like I’m doing for the Mini Sprint-T, I could at least start the frame for the Sprint-T before I know what engine and transmission I’m going to use, because there are just a few pieces that change depending on the powertrain. Basically there are two verticals in the front hoop internal bracing, and the transmission crossmember that change position depending on what turns the rear wheels. So if I get a good payment from one gig I get the raw stock for the frame and start cutting and tack welding.

And I need to get to bed. My neck hurts and I’m trying to not faceplant in the keyboard of my new laptop.

Not making much progress

I have been thinking and researching and thinking some more, but I still don’t have much in the way of progress to report. Also the injured finger has been breaking open and bleeding all over things, which can get a little messy as well as not safe because of spreading a growth medium for germs, so I took a walk to the CVS and bought a fresh box of bandages using the last bit of money left in the gift card this one gig I work uses to pay me. But seriously, I really had to buy a box of bandaids yesterday. When I take the old bandaid off the clean the finger I’m constantly snagging the flap of skin still attached to the finger and pulling it up and causing the injury to bleed like mad, but the flap is still alive so I need to keep it attached to the finger so it will heal. The situation is unless I can keep that flap alive I will have yet another nasty scar on my finger…

The issues with the finger also affect the Mini Sprint-T. My dexterity is reduced and my grip is hindered and that means making the kind of precision cuts needed to build the frame is a no-go until the finger is healed enough to work without the bandage. A slip of 0.01″ translates to a part that is a scale 0.25″ too big or too small, and wasted raw stock if I make it too small. So I have to wait until I can handle my tools safely before I can get to work on the Mini Sprint-T. If there is one thing I have learned in my 60 years, it’s patience. I will have to wait.

Another thing I have had to worry about is the weight of the front axle assembly with all the bits and pieces attached compared to the sprung weight of that end. There is nothing I can do about the excess weight except turn the heavy bits into “drillium”, also known as “swiss cheesing” the parts. The process involves a drill press, a lot of time, and usually several worn-out drill bits as holes are drilled in areas that don’t get a lot of stress in use and shouldn’t suffer fatigue failure. This only goes so far, and the parts that have the highest weight can’t be drilled out, like the spindles and wheels and especially the tires. Drilled tires would be useless. 🙂

And my finger is starting to hurt from typing, so this is pretty much it for the day.

All-Star Weekend!

They are racing for $1,000,000 tonight at Charlotte Motor Speedway. One of the things they do with this race is test proposed changes to the rules and there are a bunch of changes this year to the aero and engine. Yesterday’s qualifying already showed the differences in the specs made for differences on the track.

OK they are running the Open, and the aero changes have the racing almost like ‘Dega or Daytona, and the restrictor plate has them all running pretty equal.

OK the Open is over and they are doing the driver introductions for the All-Star Race. Signing off now.

No NASCAR race, and trying to rain here

No race to watch on the flat screen, and the weather is threatening so I can’t go for a walk. That means I have to post something here or go crazy. Going crazy is no fun, and I think you have figured out by now what choice I made.

On really good thing about the Pentastar for the Sprint-T is its extremely short length. There’s 43″ between the firewall and the centerline of the front axle on the Sprint-T and allowing for movement the steering linkage is 7″ behind that so 36″ from the firewall to the effective limit on the space. There’s a 3.5″ thick radiator to leave room for and a 9″ long steering box with a steering shaft that has to snake around the radiator, that goes between the radiator and the axle. Measuring the space from the part where the Pitman arm bolts to the rearmost part of the box as installed on the car and adding the working length of the Pitman arm (7″) I get another 12.5″ between the steering linkage and the radiator leaving just 23.5″ unless I put the radiator over the steering box like they do on the Speedway T-Bucket kit. Putting the radiator in the space between the front of the box and the steering linkage solves a lot of steering issues at the cost of raising the CofG slightly, but the radiator is only 19″ tall and there is literally 27″ to put it in. Mounting the steering linkage below the axle leaves even more room for the radiator in front of the steering box because the radiator can go over the linkage and still leave room for the axle to travel up and down. At this point in the design the radiator is a box that is 26″ wide by 19″ tall and 3.5″ thick that can be moved back and forth and up and down until room has been found for everything else. Anyway, the engine is a 20″ box in front of the firewall that leaves 16″ for everything else. And here you are reading in real time my thought processes as I build the front end of the car.

Recentering my thoughts, there is 16″ between the steering linkage and the front of the engine, the problem is the steering box and the radiator are trying to be in the same bit behind the axle. I could put the radiator on the right and the steering box on the left and have room for both. The steering box is 4.5″ from the mounting face to the right side of the box, 5.2″ total width, and I have 34″ of width to play with behind the axle, 17″ on either side of center. That means I could stuff a 28″ radiator in the car and still not hang out past the frame rails/4-bar if I put the radiator next to the steering box. If I choose to slide the radiator between the steering box and the steering linkage then I have more room for radiator width, but only just, and the radiator outlet would have to be passenger side to prevent interference. The widest radiator I can get a passenger side outlet at the places I’m looking is 31″ which is the inside to inside width of the bottom frame rails when I build to a width of 34″, serendipitous isn’t it?

And it’s time to check e-mail and get ready for bed.

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.

Comparing forward and conventional driver seating

Watching the Canadian GP on the idiot box while waiting to walk down to the phone store and pay the bill. Aside from Hamilton running away and hiding from the rest of the field it is a good race to watch with lots of close racing all up and down the order. And in a few minutes the Cup race from Pocono starts.

You have heard the saying about a picture being worth a thousand words, and my usual post is about half that. So instead of talking about the difference in the driving position I marked the body with the rear of the conventional driving position to go with the previously marked far forward driving position.You can easily see how far forward the driver gets moved
The forward mark is the same one I used before, same piece of tape even. The rear mark is what I get by putting my feet behind the original firewall. That tiny piece of tape was the inside edge of my butt marker from when this body was going to be a front engine bucket with two seats. Yes, my butt is that narrow, the outside edge is the edge of the floor where the body turns up. And moving my butt that far forward only changed the weight bias from 63% rear to 60% rear without the 0.25″ floor pan under said butt.

OK F1 race just ended and Hamilton finished like 20 seconds ahead. Except for the usual first lap/early race carnage most of the attrition was brake failure except for one engine vibration retirement to keep from scattering the engine on the track. So now I switched to the Cup race at Pocono which is still in Stage 1 and drivers are already complaining about brakes going away, which partly shows why I want to make sure I can get enough tire to make good use of the big brakes on the TGS2. I know with the rear weight bias the front brakes won’t get as much use as they would with the front engine, and the rear brakes will see much higher temperatures than with the front engine.

And Junior just missed a shift and damaged the engine. And now it has been a few laps and Jimmy Johnson and Jamie McMurray both just had brake failure in the same turn, same lap to crash within feet of each other with McMurray catching fire from the impact damage. Jimmy absolutely nailed the wall, almost knocking it down. He got out under his own power but had to catch his breath a bit before taking the mandatory ambulance ride, while McMurray was in such a hurry to get out of his burning car he didn’t disconnect the AC hose and was walking around after the wreck with part of it hanging off the back of his helmet. Race has been red flagged because of the mess in turn 1, when Jimmy hit a lot of parts and pieces fell off the car and fluids ran on the track.

And Ryan Blaney just beat Kevin Harvick to the checkered flag. Sorry I got hung up with watching the race and forgot to report on it, but if you were interested in the race you would watch it I guess. And to add fuel to the Ford v Chevy wars, Harvick did the 3-2 instead of 3-4 shift and his Ford was fine but the Chevys all blew up in the same situation. And a Ford won.

I just saw an interesting use for coal, a carved anthracite trophy at Pocono. I don’t know if the eagle is made from coal but what is under it is.

And it’s time for me to walk to the phone store and pay the bill.

Still thinking

One of the things that has been gnawing on me a little is I missed another Ride of Silence this year. For those new to my blog since I dropped the bike wrecks click on the tag RoS or Ride of Silence to see previous posts about it. I started missing the RoS when the tumor on my neck got so big that I couldn’t ride any bikes. But after Chris Christie was removed from my neck I got to the point I could ride bikes with a very upright riding position or recumbents, but not very far. Well now I can’t ride anything except a bus or car because Arthur Dent is causing troubles. I have a pain that starts in the middle of the dent and radiates to the end of the trapezius in one direction and up the back of my neck in the other, and makes my deltoid and rotator cuff tingle like they are trying to go to sleep. It’s very annoying but not much of an impediment except to bike riding at the moment, but it feels like it is trying to get worse.

I’m stalled on the Mid-Bucket (aka the Thunderbolt Grease Slapper 2) ATM because I lack cash for parts or raw stock. I still haven’t replaced my ID since the last time I lost my wallet, because I needed my ATM card to get the cash to pay for it. ATM card should finally get here this week and I will renew my ID early so I can go to Nashville and see the eclipse this August. When I get stalled on one project my mind starts on a new project immediately, in this case a lighter weight version of the Sprint-T with the Pentastar V6. Basically it is just the same as the V8 version with lighter components because of less weight and lower power. Remember the vicious circle of too heavy so other parts have to be stronger and heavier making the car heavier so other things need to be stronger…? Well this is the benign circle of less weight allowing for less heavy supporting and connecting parts. And the weight came to under 1400 pounds with the balance almost 50-50 I can use all the same size wheels and tires on each corner. If I could have gotten one of those free things would have been a lot easier.

Pole Day for the Indy 500 is on the idiot box so this is time to wrap this up. Congrats to Kyle Busch on winning the All-Star race last night in a masterful performance. Condolences to Sebastien Bourdais on that wreck at Indy yesterday and wishes for a quick recovery.

Opus the Unkillable

I’m fading here…

They’re 100 miles into the World 600 and I’m having problems staying awake. Not because the race is boring, but because this is my third race of the day after the Monaco GP and the Indy 500. After the wet race at Monaco, and the 100th running of the Indy 500 being won by a rookie my adrenal glands have burnt out and I’m about to drop… There is a limit to how much excitement a human being can endure.

It’s a good racing day

There were two races and two qualifications on the tube today, (there is only one CRT display still working in the house, can we still call TV “the tube” when it’s all flatscreens?).

First up was the Xfinity race from Richmond, won by Dale Jr. in a squeaker which you would not know from the statistics of the race. The race was 140 laps and it went green to around lap 100 with most of the field a lap or more down. Then the fun started when someone spun and brought out the yellow, bunching up the field and putting everyone up in everyone else’s grills and bumpers. That’s when it started looking like a short track race again. Lots of beating and banging, a couple cars into the outside wall, and at least one in the inside wall, and that was just the first turn after the restart. Eventually they managed to get to the end of the race with Overtime.

Then it was qualifying for the Verizon Indycar series in Alabama. Barber MSP is a fantastic track and they set a new lap record during qualifying today. I don’t know if that was a series record or the absolute track record, but either way it was danged quick. The guy who won the last race in Long Beach won the pole at the first purpose-built road course, showing how “wonderful” I am with names.

Then it was qualifying for the Paris ePrix with Sam Bird winning the pole for the first event at the facility. Because of the format for qualifying pole wasn’t set until the very last guy crossed the timing line, making for great drama.

Which lasted for all of one commercial break as they went from qualifying to the tape-delayed broadcast of the Paris ePrix. Bird got passed by DeGrassi (not the guy they named the ’90s TV show after) on the start when Bird used just a touch too much of that “instant” electric torque and smoked his tires off the line, falling to third behind his teammate. One of the interesting things about Formula E is because they run on what is basically a street tire you can hear a slight howl when drivers run at the limits of adhesion braking or in the corners, giving spectators and TV audiences a much greater insight as to how hard the drivers are pushing their cars. Anyway DeGrassi went wire to wire after the start, but there was position-swapping just anywhere you looked in the order once you went deeper than third place. The finish was disappointing because the track was partially blocked by a wreck and a Safety Car was deployed to slow and bunch the field for the finish, but they couldn’t clean up all the debris that could cause a flat tire before the laps ran out.

I have been pondering changing the drivetrain for the Sprint-T (again). Basically everything I want to do with the car could be done with 2 gears in the transmission and a box of QC gears to swap in the rear end. I mean sure the car would be a lot peppier around town with a 700r4 or 4l70e, but the entire point of the car is a race car for the street in a class that has no minimum weight, and a Powerglide is 50 pounds lighter and less expensive (oops, PGs have gotten a lot more expensive in the last few years) than either of the 2 4-speed slushboxen. I can even get one that uses the same lockup converter as the 4-speeds so that I get the same highway fuel economy. Basically the setup would be to run the same final drive ratio (2.66) as I would get with the 4-speeds in overdrive 4th gear, then when I get to the track swap out the spur gears to something that redlines at 60 MPH in low gear like I would have with the 4-speeds. The extra gearset would be $70 from Speedway.com, the quick change drain pan costs $40. The combination of an aluminum head and block LS engine and a PG transmission would take the Sprint-T from 1750 to 1600 pounds curb weight. Less weight means more grip from the tires and less work for the brakes and engine.

So, good races, and possible lighter and better performing Sprint-T. Sounds like a productive Saturday.

Picture post from Wapsicon 2015 and other things

I mentioned a while back that I spent a Saturday mid-day celebrating a certain web comic with others of a similar bent. One of the things we exchanged was something called a Munny World, a blank figurine with some wipe-off markers to decorate it. We were requested to use the markers to create a version of a Wapsi Square character and post it to the Internets.

The character I picked was Phix the Sphinx Librarian.

Also I finally got around to downloading some of the pictures from the State Fair. Here is Denny Hamlin’s show car.

I will be back tomorrow with my regular Sunday post.
