secondly, the ford ranger pickup often came equipped with a lower gear ratio differential and tranny, for towing and whatnot, while poontangs (as well as all passenger cars) come equipped a much higher gear ratio
the ranger "sport" package had the higher gear ratio (the same as was used in rear wheel drive passenger cars at the time), and was ill suited to heavy work.

There it is, how could I be so blind.
The "poontang" would do 120 in fifth taching like 2...something the ranger would not.
Come to think of it, I heard the lightning had the poontang gearing.

Much obliged.

yeah my mom had a 80's "mustang" it was a fucking four cylinder, how crass.

It was ironic....in the late 90's I had a danger ranger....2.3....moms had a 4.6 mustang GT....the stang actually got better fuel mileage.

Can I attribute this to power:weight efficiency?

I think it was.... 84? had the mustang SVO 4 banger turbo...

A buddy of mine had an s-10 with a 4.3 in it, and that was THE WORST thing I've ever seen on gas. No fucking power, giant heavy ass engine, and drank like a fish.

cars like the Tesla S in our future?




80's and 90's Poontangs in our future?




No Thank You

No. the turbo would have been admirable at least lol.....it was the base model turd muffin.

Edit: some dude at work had a luv with a v8 shoehorned in it....it was siiiiick.

When I was in high school back in the late 80's, i had a few friends who had some pretty bad ass 5.0GT's.

Had a dude with a 90's LX and a 5.0 crate motor race my Suzi Bandit 1.157 for $100.....drinks were on me that night but that fucker was pretty fast.....also I botched the start...front wheel got too high, had to clutch it down lol

I completely agree with the cadiliac and lincoln SUV statement, but I fail to see why you called the retro muscle cars faux as a lot of the modern versions come with more horsepower then the og models did.. not all mind you, but a good enough % that I wouldn't just write the entire class off as faux..

No kidding. The current Mustang GT and Chev SS are creditable efforts, fun and almost reasonable in their gas use.

Inductive strips to charge electric vehicles. Who pays? or will it be wealth redistribution? Induction wastes energy - like doc said, every converson of forms of energy depleates the original amount. my phone has inductive charging (is inductive the right term here?). It get hot. heat is energy, usually heat is wasted energy. Nice idea though.

centralized generation of energy. This is an excepton to the rule. lage plants that use heat in one form or another to generate electricity can recycle lost heat - cogeneration plants abound, recycling "lost" heat in for other purposes - heating homes through piped steam, capturing heat to rotate fans and generators. None of this is possible currently with combustion engine vehicles that only vent heat.

Methanol is not particularly energy dense, petroleum is much more so. we get a freebie with petrol, the energy it containes was collected by the sun a long time ago and it is a gift (with clauses, namely carbon and pollution). Not so with any other combustible fuel.

Hydrogen has a very small window of combustability, the mixture of hydrogen and oxygen is very narrow. The majority of cheap hydrogen however is derived from petroleum, cracking water is very energy expensive However, in order to have the energy density of gasoline, hydrogen has to be compressed to between 10,000 and 15,000 psi. This is doable but unpleasant. The cost in energy of 1. compression to that level and 2. moving a container strong enough (and thus heavy) to contain the pressure is a debit to the overall energy content - just as batteries are. This is to say nothing of liquid hydrogen where energy has to be expended to cool the gas to a liquid and then keep it at an ultra low temperature.

CNG has been and is being used with great success, regardless if the imbicility of the user, few accidents have occured, therefore it is viable.

fis no free lunch. Gasoline is pretty much the perfect medium of energy. It is light, it is liquid at normal temperatures, it is relatively safe and for now, fairly easy to harvest.

however, electricity can be harvested in a number of different ways, solar, geothermal, wave energy, wind, hydro, fission, salinity differentials. Most of these only work on mass scales. Even given the loss over transmission and storage, in the long run it will be more efficient than other forms.


Face it, gas is the best - and the worst.

Easily the best post here about the bigger picture that Elon Musk's vision- both car and Supercharger network- represents, which is really a struggle for who gets to deliver energy to our country.

Cowell and petroleum have a powerful, well entrenched stranglehold, but that does not make them either all bad, or all good. Did you know that certain types of high temperature fuel cell plants can utilize coal effectively? I'm not sure about emissions yet, but efficiency gains count, wherever you find them.

Speaking of which, however you feel about fracking the fact of the matter is that well have plentiful natural gas for a century, and it well be cheap. This has several edges; yes, it contains carbon BUT the least of it besides hydrogen itself. It can be easily transported via pipe, and its. It can be used for heat or power generation via a wide variety of devices, and capturing any excess heat and reusing it qualifies as cogeneration. Thus, it's the best fuel for energy generation currently widely available. Where to use it?

I suggest we generate our electric at home, via power generation from our own natural gas source! Why not? Generate your own power and nothing is lost in transmission! Send the excess to the grid, for credit later! Heat created during the process can be effectively used since it's at your home! Here's the best part; this is all true, no matter what kind of energy conversion device you use... except your furnace.

The best of these devices is also not brand new tech, but fuel cells are finally becoming affordable. Installed at home, using natural gas to generate power and heat that are both used on site. Oh yeah, they make one other thing, too; pure CO². Seriously! That's where the carbon in the hydrocarbon the fuel cell system uses ends up. And people wonder why I want to live in a greenhouse!

So, fuel cell takes the most reliable, affordable and abundant form of energy currently available and cogenerates heat for house, etc, and electricity for home... and your electric car. Finally, the reason for this post! One's car can and should be an energy storage and conversion device, but in really shouldn't need to convert more than one form- electricity- into comfortable, efficient, reliable transportation. In fact, in Denmark today there is a program there electric vehicles in their thousands help to buffer the power grid of the entire country as it manages usage flows through periods of windy or calm conditions affecting its wind turbines, etc. The country borrows the power to cover shortfalls, then restores it as there is surplus. Everyone benefits from a much higher proportion of energy from renewables and in Denmark's case this is important as it has very little petroleum of its own.

Moving on. Someone complained about electric motors not being high tech enough for the future. I see no one complaining about the tenure of the wheel, however. Why not? Simple, wheels are the best there is for the job. So it is with electric motors; with just one moving part, 96% plus conversion efficiency of electricity to torque, 100% of which is available at zero rpm, the modern electric motor is the wheel of our current industrial lifestyle, forget the future! Try to think of any sizeable appliance without one in it! Your TV has them. Handheld videogame console. Fridge. AC. Computer. Your smartphone. Shit, they will even regenerate electricity from torque with the flip of a switch, so the car can go further. Until a better device for converting power into momentum and back is devised, I'd say mankind is on safe ground with current electric motor technology, lol

No, it's the battery that took some work, and the charging system. Once again, Mr. Musk has been thinking ahead because he backed every horse in the race; low voltage trickle charging, high amp home charging, high power DC charging for fast charges when en route... AND, finally, the Tuckeresque move of hot swapping the whole damn battery outright!

Electric cars are going to take over, and it will be a good thing. Your sexy exotic power cogeneration system will stay safely tucked away at home, where all its features will be put to good use saving you money!

Buy fuel cells now, and convert your power bill from electric to gas, usually at a big discount. The things pay for themselves in my market in just over five years based on the savings in electricity production alone, not counting the cogenerated heat at all- or the CO² for that matter! And if some of that power runs your electric car, you are saving the big bux!

So if you believe in electric cars, and I do, then your best BEST bet is to buy your fuel cell cogeneration plant and install it in your house right before buying your electric car. Used. From some guy who got tired of his Tesla and wants a Corvette...
