  1. I have no idea what set that off or what you THINK you know about what I believe or how that played into the word smithing above. But you might be surprised to know I didn't fall off the turnip truck last night and have made many of the same observations you have and to many of the same conclusions. I know how this works.
  2. If I had a dime..... Adding to @asilverblazer comment. Imagine a spring of infinite rate. Solid. You go over a bump of 1 inch the entire truck rises 1 inch or more if you're running fast enough to loft it. This is kind of what an unloaded truck is. As you can see there isn't a shock that will handle that no matter how it's valved. A passenger car has a spring stiff enough to suspend the car with the spring compressed half its distance and fitted with a shock absorber whose stroke length is equal to twice the distance from unloaded to sitting pretty plus perhaps an inch to prevent bottoming to topping out. The springs 'range of motion' is an engineering parameter of the design. The amount of dampening the shock provides is enough to handle a bump or drop that is 90% of 1/2 the compression range....at a speed that is equal to the maximum expected in the service it's placed. Got that? Now you buy a pickup whose 'intended service' is hauling its maximum payload at the maximum posted limit over the county's average road surface. Which these days is about 2K pounds more total spring than the empty pickup needs, drive 10 over the Intestate limit on crap roads. Hence it approaches the 'infinite spring rate' scenario I presented in the first paragraph. Nutshell, there is not a perfect shock for an over sprung (infinite rate) situation. You can add weight until your (truck is) happy or you can change springs (give up load capacity) until you're happy OR you can drive at a speed (really slow) that allows the tire to do the springs job. But you can't 'valve' your way out of too much spring rate. I took 20% out of Peppers front end and 15% out of the tail and changed to linear rate shocks AND slowed to 55 from 70 mph to get a 'noticeable' improvement empty. It still leaves me with enough surplus rate to carry a literal half ton. It's enough for me. And it's all I can do without giving up travel. The next softer spring would require 'preload' to keep the shock in the center of travel and the A arm geometry happy. It would improve ride and eliminate about half the roads I travel from my using them.
  3. Home during the salty months. Garage is full of Buicks. This is her eighth winter outside. No rust. No salt. I'll mover her after the spring rains.
  4. The "Roughing the Kicker" call against SF in the first game should have been "Running into the kicker". He did NOT hit the plant leg and the booth referee even made that observation and then said, "same thing" which is is NOT and the exact difference between the two fouls. "Running into" would have been 5 yards which was a yard shy of the first down and not automatic. The Zebras gave them a fresh set and they gave them earlier at least 4 points giving credit of the catch that wasn't a catch. Even my wife who HATES football commented...looks like the bookies are wearing the stripes. Same Eagle takes out two Quarter Backs with the exact same hit to the arm that resulted in the same injury. Remember when the coach use to tell the DE to crash down on the OT's knee in high school? Targeting???? And what is with this getting up from a solid leg tackle and giving the runners leg a good twist as they walk away? Here's a new one. Two Eagles hold the runner upright and a third, from ten yards away, take a run at him putting a shoulder into his chest. Not stripping the ball and not tackling. Targeting. It's football, not Mortal Combat.
  5. "Upgrade" has a catchy sound to it...doesn't it? Have you noticed the price of diesel is high enough to eat the entire difference in fuel cost and then some? DEF cost. PPF issues? Your current ride, well maintained, has triple or better the current miles left in it. What "thing" does the newer truck have you just can't live without? A wireless phone charger? A third cup holder? Under dash lights?
  6. Second game was much cleaner and more competitive. Nail biter to the end. Eagles and Chiefs it is then.
  7. Not looking good. Brock out and the Zebras again changing the course of the river. Oh man I didn't see that.... Isn't that THE job?
  8. Totally understand. And you may get your wish. KC is banged up but good at the wrong time. Truthfully? I think the early game will be a more competitive matchup.
  9. Lots of 'top adding' going on. Boy am I behind the times. Marathon bought Chevron/El Paso Refining! 2018 it looks like. I don't know what they did. No eyes in that plant anymore but the current capacity is quite a bit more than the two plants alone when I was working for Chevron in the 80's. refinery_rank_2022.xlsx (live.com) Almost 18 million barrels a day total capacity across all products. So not gas alone. Everything from Ethane to Asphalt.
  10. The east plant use to be Valero and the west Conoco/Phillips. West plant has been shut down for years. That cut production to 34,000 barrels a day. EPA killed the Phillps plant. Suncor bought both. Upgraded one and shut the other down. Supplies roughly 35-40% of motor fuel for Colorado. Something similar happened in El Paso when Chevron bought El Paso Refining. EPA mandates caused shutdown of the older part of the Chevron crude and FCC plants cutting total production by a bit more than half.
  11. It's the nice part of being a bit older. Less of a hurry.
  12. I expect this motor will indeed by my next motor. Likely in a Colorado. It's just sad, that's all.
  13. Simplicity? Efficiency? When they say "A more efficient design"; they are not referencing the motors' ability to use fuel efficiently. They are referencing the most efficient way to get X lb./ft. torque. It is a nature of the design that allows this power on slightly less fuel. Sounds like hair splitting I know. In the days of the flathead if you needed more power, you added displacement. When the OHV motors arrived the 'design' allowed more power from the SAME displacement making it a more efficient air pump. As time toddled on, they learned to make the OHV a more efficient combustor. Increased compression. Vortec heads. Juggling bore/stroke ratio and so on but the point is the motor made more power from less fuel from the SAME displacement. It's power density increased, and its fuel efficiency followed the improvements in combustion dynamics. By the time we reach the 21 century we have small displacement V6's and V8's making the power of 7-to-9-liter 8- and 10-cylinder motors of a few decades before on a fraction of the fuel. As a bonus the reliability and longevity of these motors increased as well. If they were to follow the natural path 'Free Valve" motors would be next and propel combustion efficiency well past the 50% mark only Mercedes-Benz race motors enjoy today. The unwillingness of the OEMs to follow this path is the wind pushing electrification. While a turbo motor is a more efficient air pump, in that it decreases pumping losses, it does not automatically make it a more efficient combustor. It's primarily a means of increasing displacement artificially. Getting a 2.7-liter motor to make the power of a NA 6 liter. This kids, causes cooling issues as combustion efficiency does not follow power improvement and now......it gets complicated. Rings seal, a thing I preach is not keeping up with power density. This is just the OEMs getting the most power from the CHEAPEST package that will last just long enough to keep expectations in check and keep Uncle Sam's wolves away long enough to complete the transition to batteries. We have the technology to do better it just isn't profitable.
  14. So, @Pryme, still loving it? What have you learned so far?
  15. December 2022 through January 2023 Fuel Log Fuel is volume weighted by measurement to 44.5% hand blended over 4 tanks. 1,102 miles using 48.333 gallons metered = 22.88 MPG at a cost of about 12.9 cents per mile. This would be a median of 26.22 MPG if running E-10 87 pump which for this time of year would be very good. This has been a very warm, snow free calendar period. I've cherry picked my driving days for best weather and road conditions. Pepper sees no salt. 0W30 oil. Accurate tire pressure monitoring. And dialing back on the Ethanol to help cold start. Last value in graph is current and only the 1,102 miles of this record. Might have dialed back a bit more than needed but it is to be wicked cold the next few weeks here.
  16. CVT Transmission Life Expectancy (and List of Cars That Have a CVT) - Spire Car Found this interesting.
  17. Hum imagine that. I made a typo. Can someone call 911? The world is ending! I wasn't speaking to you. Was I? Now I am. @txab...sorry, I fed your troll. He didn't have a collar.
  18. I wonder what the life span of a CVT is believed to be. It's design hints not as long as a clutched automatic. Anyone have an idea?
