RE: Supercharged 7.3 gasohol F-250 4x4 towing 15K trailer etc

“Misters” as in H2O injected into the intake or oiler squirting up into the cylinders to cool the piston bottoms ? Am still noodling what my 7.4L Suburban will be built to. Have tossed out exhaust turbo and supercharger, but the serpentine belt driven, centrifugal turbo is of interest...if there is enough room Not looking for 1/4 mile or zero to 60MPH, but high altitude relief...though won’t mind better boy racer attributes ...

RE: Towing Advice

Welcome to the forum ! It is a ‘whole’ system and everything is important. Plus interacts with each other with dependencies that affect each other. Length does matter, as the lever arms are longer than before. Levers for any bow wake to do it’s nasty job. Sail area plays with length and lever arms. Where the trailer axle is in reference to the coupler/ball makes a bigger difference than most think. this is part of the trailers architecture. Center line of the trailer axles should be behind the center of the total length of the trailer box. Some has it farther forward to reduce tongue, so lighter duty TV’s can...on paper. Tongue (actual loaded weight) should be about >12%-15% of the total trailer weight. The orientation of the trailer is more important, but not the only metric. Trailer should be level AFTER setting up all of the dials and knobs. Prefer pointing slightly down, but NEVER pointing up. It follows better level or pointing slightly down (after setting up). Andersen is not a fav of mine and many report here that higher weight trailers have problems WD’ing enough weight back to the TV’s front axle. I like BlueOx, but nothing against any other, except for Andersen (that is just my preference) WD Hitch systems are all good, IMHO. Make sure you have actual loaded, trailer weight when looking at the spring bars. The bars should be rated more than the trailer’s actual, loaded weight. How much depends on that actual weight vs what is available to you. WD Hitch head can be tilted ‘backwards’ on some systems. That is to point the bars downwards, so that the tensioning system has more travel. Therefore able to tension the bars more. Careful of being sent into circles dialing in one area without making sure it did’t effect another area. Just know that all the dials/knobs have an interaction with other dials and knobs. Goal is to finish with the TV’s front axle returned to whatever your OEM’s manual says. Some say back to original Fender height before adding the tongue. Others say back within some +/- weight of original axle carrying weight BEFORE dropping the tongue on the ball. Then that the trailer is level or pointing slightly down. Finally, the TV’s tires must be able to handle both the weight and the push that comes from towing. That comes down to how strong the TV tires sidewalls are. Both by construction and by how much PSI vs max sidewall listed.

RE: determining pay load capacity

Also note that tires used on a dually axle, must have the tires sidewall rating REDUCED Have to check the tire OEM’s spec page for your tire. The tires that came with your dually already has the debating by the OEM, but if your are going to re-engineer by changing sizes/class/etc...you need to know this Tirerack tires debated in a dually app Snip... Light truck tires that are intended to be used in dual applications have two "Max Load" ratings branded on the tire's sidewall. This is because the load capacity rating of a tire serving duty in a "single" application is greater than the exact same tire being used in a "dual" application. For example, a LT235/85R16 Load Range E tire is rated to carry 3,042 pounds when inflated to 80 psi and used in a single application, but only 2,778 pounds when used in a dual tire application at the same inflation pressure. This reduction in rated load capacity results in slightly larger tires being specified for the application that can better withstand the additional stresses experienced when a single tire goes flat and the three properly inflated remaining tires are required to temporarily carry the load at reduced speeds to remove the vehicle from immediate danger. This load reduction is not a concern for vehicles originally equipped with dual rear tires because the vehicle manufacturer factored it in when they specified the tire size for the vehicle.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

This article is what I’ve been thinking all the while...BEV’s are okay, but not there yet...hybrids make more sense Tesla Owners Are Buying Toyota RAV4 Prime Plug-in Hybrids Top Reason Tesla Owners Buy a Toyota RAV4 Prime– Unlimited Range While PHEVs only have a limited all-electric range, 42 miles in the case of the RAV4 Prime, they have unlimited mileage in the sense that they carry enough liquid fuel to go 600 miles or more before stopping for energy. And when they do stop, they can either grab electrons if time and charging ports permit, or they can stop for a few moments on any corner and add back another 500 miles or more in energy. The hassles and limited range associated with Tesla BEVs are a big reason many of these green vehicle owners say they opted for the RAV4 Prime. Here are their own words: - We still have our Model 3 and prefer it on trips. But it is only fair as a tow vehicle as the range stinks, and charging is a pain when towing. And to boot, most National Parks have no electric. So when we are towing, the RAV4 Prime is a clear winner. D.H. - The Prime would be for my wife and family long road trips. It may be a long time before EV’s are practical for long family road trips during busy holiday seasons. B.C. - While BEVs have made great progress in the last ten years, they are still not there yet when it comes to long-distance travel or at parity with ICE vehicles when it comes to range, charging infrastructure, or just plain old convenience. BEVs are our 95% car, but when it comes to long-distance travel, nothing beats an ICE. A PHEV like the Prime is a great compromise for that part of our travel. G.L. - Traded the Model 3 because I wanted one vehicle that could go on longer road trips without stopping every 2 hrs. C.W. - Have had a Tesla Model S for two years now, and I love it. Not a perfect car, but it’s nice not to have to pay for gas and associated maintenance. Plus, it’s dead sexy. That said, we like having a RAV4 Prime for longer trips. J.J. Second Reason Tesla Owners Buy a Toyota RAV4 Prime - Towing While not a vehicle that aimed at towing, the RAV4 Prime is used by many owners for towing. It’s rated at 2,500 pounds. Many owners use the tow hitch for other purposes, most commonly to hold a multi-bike rack. In addition to D.H. above, who lists towing as a second reason to own both a Tesla and also a RAV4 Prime, C.W added, “Backcountry camping with tow capability was an extra plus. I do 99% of in-town miles in EV. Nice to do everything with one car.” Snip...

RE: A top to bottom look at green energy

Re-read...and understand what “Pre-embryonic” means... Nano-diamond self-charging batteries could disrupt energy as we know it California company NDB says its nano-diamond batteries will absolutely upend the energy equation, acting like tiny nuclear generators. They will blow any energy density comparison out of the water, lasting anywhere from a decade to 28,000 years without ever needing a charge. They will offer higher power density than lithium-ion. They will be nigh-on indestructible and totally safe in an electric car crash. And in some applications, like electric cars, they stand to be considerably cheaper than current lithium-ion packs despite their huge advantages. Still highly debatable...and again “pre-embryonic”, but that is where most great break through comes from...just an idea... The German’s or another European inventor helped reduce the rubber tires in landfill/oceans/etc by grinding up old tires and use that in the asphalt mixture for paved roads. Extended the useful life of asphalt roads by having a higher elastic material so the pavement wouldn’t crack as easily. Coefficient of friction was also good. Down side, it still has decomposing tire dust to deal with. There is a bacteria that consumes the tire road dust...few know of this That nugget produces tiny amounts electricity and has a half life in the hundreds to thousand years Let me clear up your understanding of radioactive half life. Did you know that bananas contain a good amount of radioactive potassium 40? But you can safely eat bananas. If you ate the same amount of Cobalt 60 in your hand it would kill you. Both radioactive so what is the difference. K-40 has a half life of 1,250,000,000 years, Co-60 has a half life of 5.6 years (IIRC). One is death, the other not. The shorter the half life the more dangerous a material is, generally. This is why the radioactive waste will kill people a hundred thousand years from now is mostly BS. Reactor waste is a mix of elements. Some with a very short half life and thus very dangerous. For example Ba-139 is present in that waste and it has a half life of 83 minutes. A speck od Ba-139 would kill you right there. But you can generally assume that almost all of an isotope is gone in 5 half life's. Meaning that in 8 hours that Ba 139 is gone. The dangerous short half live stuff is gone in 100 years. !000 years from now you half long half life material that isn't that hazardous and 10,000 years from now you can figure what is left. Stuff with a half life longer than 2000 years.No as to your carbon enclosed hot stuff, it would not do a thing for a gram of Ba 139, it would still kill you right there. For a gram of Th-230 you would be fine, it has a HA of 75000 years. But you's get very little energy from it.

RE: A top to bottom look at green energy

Another interesting tech is to encapsulate spent nuclear fuel pellets in layers of diamond. That is now safe to handle. That nugget produces tiny amounts electricity and has a half life in the hundreds to thousand years Stack them up to make more voltage, but would take thousands...but...still in the pre-embyronic phase. Solves nuclear power plants spent fuel and becomes a possible power source EVERYTHING we humans can do with current technology will have a crude source process(s). That is just the way of it...for now

RE: A top to bottom look at green energy

Most all of our known energy sources came/comes from the Sun. Crude is plant or organic based, which is just another form of stored Sun energy that took millions of years to create. We are burning through it in just decades to a century or so. Wind is Sun based, as our weather is all based on solar heating/cooling to form low/high pressure areas where they push/pull air. Add in our planets rotation, which moves the air. Nuclear is questionable whether Sun based and have been in many discussions over the decades. Nuclear is the highest density form of potential energy, but has great down sides...or better stated...many more down sides. All are manageable with the big question...at what cost? On that, time factors that cost. “Clean energy” or “zero pollution” are more marketing than substantive. Go back into their origins and you will find crude at the source...as we know it today. Science continues to marvel. Example is hydrogen. Pure hydrogen used to take more energy to produce than it provides in the form of usable energy....but...that has been chipped at for decades and decades. Current best practice is photonics to split hydrogen and oxygen atoms with claimed 99% or higher efficiency. Then compressing that now very economical gaseous hydrogen into a liquid then consumes much energy. That is where one of my research teams were working on while in SunLabs We invented a solid state gas to liquid compressor with no moving parts....except for a one way valve (automotive AC and about $1.99) so it would pump. But...all that then requires electrical power, but now much into the noise level. Sizing for what society is accustomed to will be another issue, but solvable. Society will just have to change. Batteries will become obsolete except for the very small applications. To be replaced by containers holding liquid hydrogen. The diamond compression to create electricity is of interest, but currently only in the very, very low outage & power ranges. More scientific curiosity in the lab, but that is how most all things start out as...an idea...then a prototype or proof of concept model. Society will NOT willing move in mass unless catastrophe or mandated by government. Then everything in the food chain to the final usage or application of power. EVERYTHING we produce/manufacture/service/etc currently has crude base materials, processes, etc. The change will need to happen EVERYWHERE at almost the same time. Piece meal won’t cut it an too many 2 steps forward with 3-4 steps backwards. Leading to frustration of society and that will lead to distrust in the ‘new’ processes & products mandated by the government Current IP for EV’s only a stop gap and is best practices of the moment. Shinerbock has been saying fuel cell the way to go and I’ve concurred often, but that hasn’t caught on here...but current technology isn’t there yet. Generation of liquid hydrogen, transportation, storage, delivery, etc will continue to be a huge issue, but that will be overcome once ‘we have to’ Wind generators, solar panels, etc all have crude in it’s food chain big time. Just invisible to most.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

Wonder how easily Tusk’s wet Lith-Ion can be converted to solid Lith-Ion battery technology ? Then the repackaging of everything or will he able to make solid state batteries in the same form factor ? Since solid state batteries can be recharged in fractions of the time a regular lith-ion battery that takes hours...the transition will be very quick. Toyota's Solid-State Battery Will Crush Tesla Li-Ion Updates Apple or Android? Tesla or Toyota? New battery technology coming from an automotive world leader is sure to bring a massive change to the EV revolution. Visit Torque News homepage for more stories. If you talk to anyone who has been a die-hard Apple user since the inception of the iPhone, you will come to learn something about them. Apple is the end-all of smartphone technology. Android users disagree entirely with that, claiming that Android-based phones are far superior, giving them more customization and features. While that debate will rage on eternally, another fight is happening in a different technological realm, automotive. It is the battle over the electric car and the technology surrounding it, particularly battery technology. If you have ever met a Tesla fan, you will know they are like Apple users, and many of them probably are. They admire the hard work and thought put into the Tesla vehicles by co-founder Elon Musk. They look at him as some form of tech leader that has graced their every waking moment with the hope of a better future. The thing with Tesla owners is they are very rooted in everything about the company. They are the early adopters and will be Tesla owners for the rest of their lives, just like Apple users. So what happens when something else comes out to challenge the status quo? What happens when another car company comes out with something that is ultimately better? We are entering a time in history where we see this happen right before our eyes. Most just do not understand it, though.

RE: New version of Ford's 9.75" axle?

Agree with everyone and add : The old 3/4 ton Suburbans (GMT400) had the same AAM axle assembly as the 1 ton dually of the same year. Only difference is in the leaf spring pack/hangers/brackets and the brake cyclinder/MC Why parts counter will ask how wide your GMT400 3/4 ton Suburban has....there two and the difference is in the width of the shoes and drum. The wider shoe/drum also is a full floater rear end. As for ball bearings vs rollers vs tapered rollers is that the balls have a smaller contact point with the race. Therefore lower rolling resistance Rollers have a larger contact point and has a higher load rating vs a ball, but in regards to dia, the roller is rated to carry more Tapered rollers has a much higher axial thrust load rating. Straight rollers almost none and balls has some. Been advocating tossing the marketing nomenclature (1/2-3/4-1 ton, 150/250/350, 1500/2500/3500, etc) for years and just go with their GVWR. If they toss the 3/4 a step in the right direction, IMHO

RE: Replacing 1972 16.5 Inch Rims Advice

Ditto bigtoe’s comments and add... Commercial tires come in 0.5” diameter sizes and do NOT have a safety bead and they carry weight a bit different than our tirres in whole inch diameters. The safety bead is mostly for run flat and low pressure so that the bead won’t come off the rim. The pop you hear when the tire mechanic mounts the tire on wheel and 1st air to ‘set the bead’. That is the tire bead running up and over the safety bead (the bump mentioned above) and hits the wheel rim. Also why they soap the tire bead before mounting on the wheel Very dangerous to mount a whole inch dia tire on a half inch dia wheel. It will seem to mount and inflate...but it will come off the bead area easily during a hard turn or bump. To the OP, you can make the switch to 16” dia wheels and tires. It will weigh significantly less than the half inch commercial setup, but will not have the ratings of a half inch dia commercial tire...but...you won’t need that with today’s tire’s.

RE: 2008 F250 with 5.4

Tie/tape a length of string on the drive shaft. Roll the truck one tire rev. Use the valve stem as the datum. Count the number of full string wraps, that is the first number of the axle ratio Fractions of a turn is the rest of the axle ratio Remove the string 3 whole turns means a 3.xx ratio 3/4 of the remaining is x.73 ratio Put them together and it would be 3.73 axle ratio .

RE: E rated tire with max psi of 65?

Burbman...your sand compacts better than the stuff I normally run on. The sand am used to would NOT leave such distinct tread pattern. It would fall apart, unless wet. Wonder why east coast sand isn't rounded by eave action as much as out here on the west coast. The 'apparent' diameter am talking about will on additional tread contact in length. Measured at the leading to trailing tread contact. That is more important, but bulge width and cupping also plays. The minimual tread penetration on your current tires look very good, considering loaded with that camper n stuff. Cleaning out the garage attic and found my old surf rods. Gave them away except for my first rod I made as a teen. Fenwick fast taper and has been rebuild several times. About 12-13 feet with extra long handle and larger diameter cork. Mainly strippers with occasion gulls hitting the metal spoon (Mickey Mouse, with a hulla skirt)...

RE: E rated tire with max psi of 65?

X2....N-Trouble’s comment/thoughts Following is more rhetorical than anything...why are folks so hung up on a tires PSI rating...when most diss the GVWR/GCWR/MTWR/etc ratings ?...and recommend that they don’t really matter... Selective adherence to ratings IMHO... Most get away with that mentality & recommendations because designers have dialed in some level of margin (AKA...safety margin as most think it is). How much they dialed in and how much management told them to remove is a guessing game or more aptly lucky that they haven’t found where that line is... Off soap box... Burbman...I’d go down in width and go to a higher aspect ratio (Larger number, which is the percentage of section width) for your setup. A higher profile tire’s sidewall will help when you go to the beach and that sand those beaches are famous for. Airing down will have a higher profile tire’s sidewall ‘bulge’ more, which forms both a ‘wider’ footprint...and many don’t know that the tread will also ‘cup’ inwards, which helps ‘catch’ more sand and NOT slip as much. The higher the aspect ratio (higher number, or higher percentage) will allow the sidewalls to collapse more. Also, with a higher profile tire aired down, the ‘aparent’ tire dia will be much larger than a lower profile tire. Around some old campfires, buddies and I noodled and came to a consensus that our tires were in the effective +8 foot diameter range. Finally, note that squared off tread to sidewall transition area needs to be rounded. Street tires with a much more squared off (sharp transition) will dig better in soft stuff (dirt, sand, etc) Edit...for those who don’t know...airing down is for very slow going ONLY. If you plan to drive above, say, 10MPH with aired down tires...that will shorten your tires life greatly. Go faster and you may not make it back to pavement with the tires in good condition.

RE: GM's Max Trailering Package

X2 to Jerem0621;s comment and add...going by marketing nomenclature is risking getting caught in the marketing “king of the hill’ positioning where things are taken out of context (true, but not the whole picture) Suggest looking at the OEM ratings and do the simple math using their ratings numbers. GVWR, front & rear GAWR and their listed curb weight (not the old stripper model they used to employ for these “King of the Hilll” marketing, but their true weight as shipped from the factory) But first decide if you believe in the OEM ratings. Huge and never ending discussion on ‘which’ ratings to ignore or follow. It is a very personal risk management decision. IMO, the most important is the rear GAWR, then GVWR, then the rest of them. Actual weights best, but if you do not have one or the other or neither...use their listed GVWR & tongue (that will provide the basic tongue percentage to calculate vs the actual weight) Most of the weight on any pickup will be over the rear axle. Look at any pickup from the side and notice that the rear drivers door edge is about half way between the axles. Meaning anything loaded in the bed and/or on the ball will place the majority of that weight over the rear axle. Why as you move up in the capacity/rating scale of TV’s, the rear GAWR jumps higher. Why half ton’s have many different rear GAWR and higher class starts at 6,000 rear GAWR Nothing wrong with any pickup class, but just understand that and forget using marketing nomenclature Also, understand the “corporate component/systems stock room” and is where many think they can guess which parts are needed to increase their ratings. They maybe correct, but that doesn’t change the OEM ratings.
