That torque plateau is nuts.

I’ll second this assumption. I just pulled about 6K lbs 300 miles this weekend with my 2001 GMC with a 6.0 in it. Less power when new, and its got 18 years of power loss. It did fine. When comparing spec sheets between new trucks you loos site of how far we have come, and how much power it actually takes to safely…

I live on a farm, where there is always something to do. My 1/4 acre subdivision dwelling co-workers can never understand why I never come out with them. Its because THERE IS ALWAYS SOMETHING TO DO when you own land. My vegetable garden is bigger than 2 of my co-workers lots. They would have a wake up call much like…

Nope, buy crashed 2018 Mustang for scrap value (under $2,000), splice ID tags onto Cobra Jet, re-title as “Salvage Title”. Drive Cobra Jet to and from the grocery store. Much less wrenching, and honestly not that shady.

Makes sense, I’m familar with PV=nRT, but never thought about the compounding increase in pressure due to the increase in temp along with the volumetric reduction. Thanks for the thermo 101.

Can attest, I’ve never been on a trip of any length with a woman where she didn’t pack 3x what I did. Work trips, personal vacation, trips as a kid my mom used to pack 3x what my dad did, spring break in college, trips to the grocery store.

I’d be willing to bet they thinned it with regular 87 until the diesel contamination levels reached an acceptably low level. Then sold it as regular 87 to gas stations where it was mixed even further.

Yep, to get the fuel supplier to pay you’ll have to prove they knew it was bad fuel and sold it anyway.

Can you explain the 370 psi at a 10:1 compression, why would it be over 147 psi? I’ve got a loose grasp on thermodynamics, but not enough to fully understand the adiabatic process.

No CR, is simply a ratio of two volumes. Fuel will ignite at a certain heat/pressure. So the cylinder pressure at TDC can only get so high. 10:1 at 14.7 psi is 147 psi, a boosted engine with a lower compression ratio say 8:1 with 10PSI boost has a maximum cylinder pressure of 197 psi. Not double the pressure but you…

To further this, it does not change the static compression ratio at all, but it does increase cylinder pressures. In a Naturally aspirated Engine the atmospheric pressure is 14.7 psi, on a 10:1 CR engine, you end up with a final cylinder pressure of 147 psi. However if you put 10PSI of boost on it, you start with 24.7…

Yep, modern tech gets outdated so fast that those are worthless.

I’m an engineer, and to be honest most engineering equations have not changed since their derivation. So a 60 year old steel design manual, has the same basic equations as a brand new one. Frictional losses in pipe hasn’t changed a bit in 50 years. Its about being comfortable with a reference material and being able…

I’m the same way. I’ll get rid of it, only when I dont think it’ll ever come up in conversation. If I could see myself every saying “I read a book on that one time, here give it a try” then I keep it. Random Sci-Fi, super dull non-fiction, or really obscure stuff gets passed on as soon as i’m done with it, or decide…

South Carolina here, and it was on PBS. Seems like I remember watching it later on Saturday Evenings.

Your right, they do already make the perfect pickup:

Recently got married. By adding my Wife as a driver, and her 5 year old car to my existing 2 car policy, my total annual premiums went up less than $400. A change of approximately 15%. If I had not added her car my total premiums would have gone down by about 20%.

Also covered parking ages. Paint fades, color schemes go out of style, and general architecture changes every 10-20 years. So the dealer is looking at replacing or doing a major overhaul of the structure every 15 years or so. Or pay a little extra insurance for a hail event that might only happen every 10 years. If I…

Its called publicity. You just named off those companies, free publicity. They are probably rolling the dice with the money that this truck may or may not make it into production in the next 5-7 years, and it may or may not be piratical when delivered. But the exposure and appearance of being “green” and “low…

I think he’s talking from an engineering perspective. What does that high amp draw, and having to cool all those electric do to the range?
