RE: 2015 GM Trucks will get 8 speed Transmission

The six speeds are actually four speeds with double overdrives. The eight speed is a six speed with double overdrive. The overdrives are a wash. When a four speed has to shift down from 1:1, it goes to third. When a six speed has to shift down from 1:1 it has fourth and fifth to chose from before it gets to third.

RE: Vancouver/Victoria, BC 5er travel

Northbound Soutbound Click on the cameras to get a real time view of the lineups. All the crossings can be bad at times. These are the two sites we use. If you want to avoid Seattle, take 101 up the Hood Canal and make a stop at Fort Worden in Port Townsend. It is a beautiful drive and they are well worth the visit. From there you can either take a ferry from Port Angeles to Victoria or across to Whidbey Island, From there, either take the ferry from Anacortes to Sidney or pick up the I-5 again at Burlington.

RE: GVWR's

Better check GCWR while you are looking...that is usually the limiting number Depends what you are towing. With 5th wheels it's usually GVWR. Payload will change depending on how a truck is equipped, GVWR won't.

RE: 5th Wheel Reliability

Too bad northwood rvs seem to be really hard to find east of the mississippi everyone seems to speak highly of them. Love Arctic Fox but just too expensive and heavy for me. The newer Fox Mountain line looks promising. Much lighter and less expensive so wonder if they have the same build quality as their higher lines. Expensive and heavy. My thought as well. Have looked at the Fox Mountain, nice but wasn't overly impressed. We settled on our Grand Design Reflection as the best combo of length, weight and layout for us. Fit and finish is outstanding for a unit in this class, durability to be determined.

RE: Where is "level" determined on a fifth wheel?

I use the bottom frames of the basement storage openings. Wife likes it about an eighth of a bubble nose up so the bathroom door doesn't swing open and she says she sleeps better. :h These things are pretty flexible and the chances of getting the whole thing level are somewhere between slim and none. Seems to work fine, the original Dometic fridge was still going strong when we traded our 13 year old 5er in last spring. We do most of our cooking outdoors so don't care if the range is level.

RE: Loading weight & distribution on a 5th wheel

As with a travel trailer. moving the center of gravity forward will make it more stable (same goes for all vehicles, including aircraft up to a point) but you don't want to overload your truck. You could weigh the trailer, find its center of gravity, then calculate the moment for everything you add to calculate a new center of gravity as with an aircraft, but what a lot of work. It ain't that critical. If in doubt, put it over or forward of the axles. You will find your fifth wheel more stable when towing than your travel trailer so enjoy.

RE: 2015 GM Trucks will get 8 speed Transmission

Hard to say how far the CVT can be developed but they have come a long way. Nissan is using one behind 3.5L V6's putting out 290 HP in the Murano and Maxima.

RE: 2015 GM Trucks will get 8 speed Transmission

I have an 8 speed, and it definitely does not hunt for gears. Do you tow heavy with it? Shouldn't matter if they get the software right. We already have tow haul modes that adjust for heavy towing. Transmissions hunt because they can't find a gear that is the right ratio for the particular condition, so they go back and forth between two, neither of which are suitable for the speed and power required. More gears just gives a better chance of having that right ratio and should result in less hunting.

RE: SRT Charger Hellcat

I must correct you. The Hellcat does the 1/4 in the low 10's...quite a bit quicker than the Nissan....which is around 10.8, 10.9 seconds. I'm seeing several runs made by various groups. From 10.8 to 11.2 for the Hellcat. Most reports are showing the 11.2 time including Dodge. Nissan reports 10.8 for the GTR. Where did you see official times under 10.8 for the Hellcat? Motortrend Magazine shows 0-60mph 2.7s for GTR, 3.5s for Hellcat. The GTR's AWD gives it a big advantage over a 2wd getting the power to the ground, paricularly 0-60.

RE: Ram Eco-Diesel vs F150 2.7 TT - Davis Dam

Want to muddy the water with turboprops? Better not. Or even worse, ultra-high bypass ratio turbofans, where a significant amount of thrust comes from the intake fan turned by, gasp, torque... True but RPM determines how much power is being produced by that torque and of course in the case of rocket engines, none of it is produced by torque. Yes. What I meant is a turbofan produces both direct thrust (via jet nozzle) and propulsion via fan/prop. On a 0 bypass turbojet, or rocket, it's all thrust. (shaft power negligible) On a turboprop, it's all shaft power. (exhaust stream negligible) Therefore a turbofan is the most difficult to calculate. Industry rates them by thrust for simplicity sake, but it produces significant shaft horsepower. Its ratio of shaft power vs thrust power changes with altitude. Engine manufacturers don't even agree on which power setting parameter to use. GE uses fan speed, N1, for all its turbo fans. Pratt and Whitney and Rolls Royce use engine pressure ratio, EPR, but not necessarily in the same way, depnding on the engine.

RE: Ram Eco-Diesel vs F150 2.7 TT - Davis Dam

The question wasn't for you. I am agreeing with you. Mostly. I'm surprised the relationship between HP and torque is so difficult to grasp and are often treated as one or the other when for the purpose we are speaking of, they are interdependent. You can't make power without torque but unless you make power, torque gets you nowhere. Power is the measure of how far and fast torque can get you somewhere. Going back to the old weight lifter analogy. Torque is how much you are lifting. Power is the number of reps you can do in a given time with that weight. Gotcha. Didn't realize you were trying to make a point asking that question... We can blame the media for dumbing things down and misleading people. And also Shelby for that infamous "torque wins races" quote, which was taken out of context for half a century. Want to muddy the water with turboprops? Better not.

RE: Ram Eco-Diesel vs F150 2.7 TT - Davis Dam

But try explaining what "torque" pulls a million pound jetliner of the ground... Torque is the lever that lifts the weight, torque is the flywheel that turns the wheels, torque is the compression, combustion and the thrust that sends the jetliner into the wild blue yonder... you can have all the hp you want.. but without the torque, your not getting anywhere. Sorry, flat out false. Horsepower gets my airplane off the ground, all 87ft lbs at 34,000 rpm, gets my rig up the hill (220ft lbs at 5000rpm. Go back to 8th grade. You have no business past that. What about rocket engines that have no rotating parts? What about when you blow up a balloon and release it? What propelles it across the room? Very simple, and it's not torque. It is thrust and speed which the horsepower can be calculated. The more horsepower the better. 5000lbs of thrust with no speed =0. The lbs thrust is in the balloon and it goes nowhere. Only when there is speed will the balloon be propelled. Go back to 8th grade and start over. I'm quite aware of that. Perhaps, I missunderstood you original statement.

RE: Ram Eco-Diesel vs F150 2.7 TT - Davis Dam

What about rocket engines that have no rotating parts? What about when you blow up a balloon and release it? What propelles it across the room? A given force at a given velocity. Multiply them together and guess what you get - power! That's why I stated power is universal. Doesn't matter where the force comes from: a blast of air, jet nozzle, propeller, or torque (which is simply force in angular domain), it generates power at a given velocity. That power is what puts objects in motion and gives them acceleration. Torque is a mean of producing power, as is the fossil fuel. Saying torque is which get you up the hill is as ridiculous as saying is the dead dinosaur that gets you up the hill. Both correct, just ridiculous in terms of physics and engineering. The question wasn't for you. I am agreeing with you. Mostly.

RE: Ram Eco-Diesel vs F150 2.7 TT - Davis Dam

If I build an engine that puts out 1000 ft/lbs of torque and limit the RPM to 1000 how much HP does it produce HP = t x RPM/5252 Horse power of your engine Turtle is 190.4hp. :) Winner, winner chicken dinner. Now answer the second part of the question. How well would a 1000 ft/lb 190 HP engine do in a TV towing lets say a 15K 5er up a 7% grade? It would do really well, just not very fast. Maybe it's ok for some but sub 30mph would not be my definition of "really well." :E If that's the case my 65 HP tractor would make a pretty good TV. :B In some ways it would make a good TV but we can carry any example to an extreme. Personally I put a premium on power in the 1500 to 3000 RPM range where I spend over 95% of my time. I may pass another vehicle on a two lane road towing my trailer once a year if that, so the ability to do so just doesn't mean much to me. If others want to make a habit of it, that's up to them. I just hope I'm not coming the other way when they are.

RE: Ram Eco-Diesel vs F150 2.7 TT - Davis Dam

Hey T&P. Remember that one person telling us that HP is just a calculation and doesn't really exist like TQ does? Lol LOL, that guy was right. Look up the definition. You will notice that 'torque' is the measure of 'work'. Work requires a force. That force is torque. All horsepower adds to the equation is time, so horsepower is just the ticking of the clock. This guy quoted below works with horsepower all the time for his livelihood and this is what he has to say about it. What This Means As we proved above, horsepower is simply an extrapolation of torque applied over time. When an engine is measured for its power potential on a dynamometer, horsepower and torque are not measured as separate entities. Rather, torque is measured, and horsepower is then calculated given the torque at the specific RPM level. Car owners often use “horsepower” as the end-all be-all rating for engine performance. This perspective is flawed. First of all, when you hear of a car having X horsepower, it only refers to the peak horsepower on the dyno graph. Secondly, it doesn’t indicate what the shape of the torque curve is. You can feel the torque that an engine generates as you’re pushed back into your seat. http://www.roushperformance.com/blog/2010/12/the-meaning-of-horsepower-and-torque/ Bye,,,,, again. But if you are talking about a chassis dynamometer (that is what you will find in the field) They measure horsepower and the torque has to be calculated. Also torque is not a measurement of work. Torque is only a force measurement. You can have a 1000 ft lbs of torque with no work being done. But if you have 300 hp work is being done. When you are being pushed back in you seat that is horsepower. Being pushed back in your seat is torque overpowering the resistance. Horsepower is just a mathematical calculation that tells you how much torque you are putting out to overcome that resistance. You are leaving out one important element. The rate it can overcome that resistance.

This guy quoted below works with horsepower all the time for his livelihood and this is what he has to say about it. No, there is another element. Distance. You can apply all the force you want for as long as you want but if it doesn't move, no work is done. Horsepower is measured in foot pounds per second. The word foot isn't there for decoration.
