General cars and vehicles thread.

Recommended Posts

   We have thread about old Soviet cars and Americal cars (that also tend to be about older and top models). This thread is general thread about any cars - new and old, racing or for work. Car news also can be posted here.

 

I begin this topic with this -

Lada Vesta - first "Russian" car that looks like it was made in same century as what we live now! It should be out soon, so i can see it on the streets and complain about it looking like new Renault Logan.

Yandex Taxi (Yandex is Russian Google, basically) launched 2 Tesla taxis as part of their fuel costs-reduction experiment. They managed to recude cost for fuel by 132 000 rubles in ~2 months, which is maybe by today exchange ratees is like 10.99$.   :D

From a photoshoot a while back in my shop:

 

 

24c5eh0.jpg

 

26062di.jpg

 

 

The GT's shortblock can withstand well into 4 digits, and Ford engineers overbuilt the hell out of it. The 4v heads flow an incredible amount of air as well, and a stock longblock with more boost than the factory twin screw delivers will put down really earth-shattering horsepower. Of course, being a Ford mod-motor, they are easy to squeeze power out of (as opposed to a Lambo that needs a shop like Hennessey).

However, to be quite honest the car is somewhat boring to drive. It accelerates so smoothly that it does not throw you back into the seat like most high performance cars do. You simply see the speedometer rushing to the peg while you try and keep up rowing gears.

 

Also, did I mention you can squeeze a lot of power out of them?

Also, a little project I have been working on:

 

https://www.youtube.com/watch?v=_QEhPwVd2AE

 

 

 

657 at the wheels (750 of so HP at the fly) on pump gas for a little 4.6 liter aint too bad. Of course the little bastard camming and the giant "HOOSIER" logos have stifled any potential money races.

I took Miles Vining from TFB/Small Arms Review for a ride when he was in town and scared the hell out of him. However it wasn't my fault: A little slammed Evo with cheater slicks, a giant FMIC, and a BOV that could be heard in the next county saw it fit to challenge me :)

Lol. Nathaniel is well aware of my passion for automobiles. Believe it or not it surpasses my deep-running appreciation for firearms!

 

But lets throw in some factoids for anyone who doesn't think much of the humble old internal combustion engine... by referencing what 500 C.I. is capable of:

http://www.automobilemag.com/features/columns/0403_top_fuel_dragsters/

 

* One Top Fuel dragster 500 cubic-inch Hemi engine makes more horsepower than the first 4 rows at the Daytona 500.

* Under full throttle, a dragster engine consumes 11.2 gallons of nitro methane per second; a fully loaded 747 consumes jet fuel at the same rate with 25% less energy being produced.

* A stock Dodge Hemi V8 engine cannot produce enough power to merely drive the dragster’s supercharger.

* With 3000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into a near-solid form before ignition. Cylinders run on the verge of hydraulic lock at full throttle.

* At the stoichiometric 1.7:1 air/fuel mixture for nitro methane the flame front temperature measures 7050 degrees F.

* Nitro methane burns yellow. The spectacular white flame seen above the stacks at night is raw burning hydrogen, dissociated from atmospheric water vapor by the searing exhaust gases.

* Dual magnetos supply 44 amps to each spark plug. This is the output of an arc welder in each cylinder.

* Spark plug electrodes are totally consumed during a pass. After 1/2 way, the engine is dieseling from compression plus the glow of exhaust valves at 1400 degrees F. The engine can only be shut down by cutting the fuel flow.

* If spark momentarily fails early in the run, unburned nitro builds up in the affected cylinders and then explodes with sufficient force to blow cylinder heads off the block in pieces or split the block in half.

* Dragsters reach over 300 MPH before you have completed reading this sentence.

* In order to exceed 300 MPH in 4.5 seconds, dragsters must accelerate an average of over 4 G’s. In order to reach 200 MPH well before half-track, the launch acceleration approaches 8 G’s.

* Top Fuel engines turn approximately 540 revolutions from light to light!

* Including the burnout, the engine must only survive 900 revolutions under load.

* The redline is actually quite high at 9500 RPM.

* THE BOTTOM LINE: Assuming all the equipment is paid off, the crew worked for free, & for once, NOTHING BLOWS UP, each run costs an estimated $1,000 per second.

The current Top Fuel dragster elapsed time record is 4.441 seconds for the quarter-mile (10/05/03, Tony Schumacher). The top speed record is 333.00 MPH (533 km/h) as measured over the last 66′ of the run (09/28/03, Doug Kalitta).

Putting this all into perspective:

Lets say the you are driving the average $140,000 Lingenfelter twin-turbo powered Corvette Z06.

Over a mile up the road, a Top Fuel dragster is staged & ready to launch down a quarter-mile strip as you pass by it. You have the advantage of a flying start. You run the ‘Vette hard up through the gears and blast across the starting line & pass the dragster at an honest 200 MPH. Just as you pass the Top Fuel Dragster the ‘tree’ goes green for both of you.

The dragster launches & starts after you. You keep your foot down hard, but you hear an incredibly brutal whine that sears your eardrums & within 3 seconds the dragster catches & passes you. He beats you to the finish line, a quarter-mile away from where you just passed him. Think about it – from a standing start, the dragster had spotted you 200 MPH & not only caught, but nearly blasted you off the road when he passed you within a mere 1320 foot long race!

 

Or by the numbers:

http://www.motortrend.com/features/112_0502_top_fuel_numbers/

 

7500 - Approximate peak output, in horsepower, of a competitive 2005 Top Fuel engine. That's almost 1000 horsepower per cylinder.

500 - Engine capacity, in cubic inches. The block and heads are CNC-milled from solid billets of aluminum, and the oil pan is titanium.

45.5 - Maximum boost, in psi, produced by the supercharger at wide-open throttle. That's more than 3.0 bar, twice the boost achieved by a Mitsubishi Evo VIII.

12,654 - Rpm the supercharger spins at maximum engine speed. With the engine at 8500 rpm, just turning the supercharger soaks up 900 horsepower.

165 - Temperature in Fahrenheit of the 14-71-type supercharger after just 4.5 seconds of maximum boost.

569 - Number of times the engine's crankshaft turns during the entire quarter mile. Each intake valve opens 284 times.

16 - Spark plugs per engine. The twin MSD magnetos produce 88 amps. You need just 12 more to power your MIG welder.

77 - Gallons per minute the fuel system can pump at wide-open throttle. The engine will consume 22.75 gallons of fuel during warmup, burnout, staging, and the quarter-mile run.

900 - Cost, in dollars, of a 55-gallon drum of nitromethane fuel. Current regulations allow a maximum of 85 percent nitromethane in the fuel mix. The rest is alcohol.

58,700 - About what you'll pay, in dollars, for a new, ready-to-run Top Fuel engine.

29 - Minutes it takes to tear down and rebuild a Top Fuel engine between rounds. Each engine is rebuilt 184 times a year (if the driver goes to the final round at every race).

28 - Quarts of oil used during warm-up and quarter-mile run. The oil pan holds 70-weight oil mixed with special thickener.

6 - The maximum number of clutch discs in a Top Fuel car. The multistage clutch is timed to progressively lock up during the run. Each $115 disc lasts a maximum of three runs.

2225 - Minimum weight, in pounds, of a Top Fuel dragster. That's a power-to-weight ratio of 3.37 horsepower per pound, about 20 times better than the new Z06 Corvette's.

300 - Wheelbase, in inches, of a Top Fuel dragster. About 3000 inches of chrome-moly tubing is needed to build the frame, which is left unpainted because of the need to constantly weld cracks.

1082 - Greenbacks you'll need to buy a pair of new Goodyear R36x17.5 rear slicks. If you're lucky, they'll last you a bit over a mile--four runs.

58 - Bead Lock bolts used to retain each rear tire to the wheel. Tire pressures are set between 6.5 and 7.5 psi. ...And Here's What It Does

0.84 - Seconds it takes for a Top Fueler to accelerate to 100 mph from standstill. At launch, drivers are subjected to up to 4.75 g--more than a space-shuttle astronaut.

333.08 - Top speed, in mph, of the 2004 NHRA Top Fuel Championship-winning U.S. Army dragster. When he pops the parachute at the end of his run, driver Tony Schumacher experiences peak deceleration of 6 g.

12,000 - Downforce, in pounds, generated by the rear wing at 325 mph. The downward thrust made by the exhaust gases escaping the headers alone generates 800 pounds of downforce.

85 - Distance, in inches, you'll need to be above the header pipes to avoid getting toasted by the nitro flames exiting those pipes.

8.5 - Number of inches the rolling diameter of the rear tires grows during a 325-mph run, reaching a maximum of 44.5 inches.

Those were pretty terrible cars overall. If you had a customer who liked it you had to be careful with the billing and parts, as it was basically a Cavalier/Skyhawk and they'd complain if they thought you were putting "the wrong parts" on their Cruddylax.

What is the Russian equivalent of a trailer-dwelling man in an incestuous relationship with a cousin who also has has poor, dated taste in music?

 

Because THAT is that dude's ride... and hopefully third-gen f body stereotypes are trans-atlantic.

I know, I was posting it as a joke.  One of GM's many missteps in the 80's.  It's too bad they didn't offer a version of the Cimarron with one of their early 80's diesel car engines.  That would have been the terrible car to beat all terrible cars.

Yeah, I figured, it just keyed up some lingering memories of that turd.

 

As to GM automotive Diesels, I don't remember seeing them in any of the FWD platforms. They seemed to lurk only in the RWD full size and midsize sedans.

Not sure why you could not have dropped one of the 6.2's into a Toronado, but never saw one.

 

Not really doable in the Cimmaron/Cavalier platform because of size, unless GM imported one of the small VW Diesels.

I strongly suspect that it's Alex's love for cars (and Russia's relatively poor showing in that field) that has led him to believe Russia produces nothing of value but the AK. :P

I am not a car person, the closest I get is wanting to own a couple armored vehicles some day, or maybe a Toyota Hilux for the lulz.

      Is there any way Sherman tanks could be upgraded at reasonable cost to still have a role on the battlefield? Assume that your military will never fight with a world-class army (U.S., Russia, China, etc.) and instead will only fight with second-rate armies using 1990s technology at best, or with terrorists, or go on peacekeeping missions. 
       
      I'm thinking that the Shermans could have their turrets removed and modern autoloading turrets from other armored vehicles--like the 105mm Stryker gun, or the 40mm autocannon from the CV10, or the 30mm from the BMP-2 (would any of these fit in the Sherman's turret ring?)--could be dropped in, along with their sensors and computers. ATGM launchers could be installed as well. Explosive reactive armor bricks could be attached to the outside, as is common among modern Russian tanks. 
       
      Assume that your Sherman fleet is 1,000 tanks, in various states of (dis)repair, so you have enough spare parts to last for many years. 
       
      What do you guys think? Thanks.

      So, basic introduction, to start off, we'll go with the latest backbone of the PLA Ground forces' Armored divisions, the ZTZ-96 G/A
       
      Basic specs.
       
      Crew: 3
       
      Weight: 42-45 tonnes depending on equipment and addon armor/era.
       
      Power plant: 1,000 hp liquid cooled Diesel engine
       
      Speed: 65 km/h on roads 45 km/h off road
       
      Range: 400km without external tanks
       
      Armament: 125mm L/48 main gun with autoloader similar to the Soviet 2A46 (8 rounds per minute rof), ATGM capable, based on Russian Refleks-M missile, also has HEI-FRAG, HEAT, and APFSDS ammunition choices, W-85 12.7mm cupola machine gun (not pictured in this photo), 7.62mm coaxial machine gun.
       

       
      Wow, such sharp looking, very armor.
       
      Capability wise, this tank was recently pitted against some modern T-72B variants in a Russian tank Biathalon, and while it was deemed better in Armor, Armament, and Electronics, it lost out in mobility due to the underpowered engine, this killed all 730 and 780 hp engines in other ZTZ-96 G/As for the 1,000 hp engine.
       
      One interesting note: the boxes on the side actually contain equipment that interferes with the targetting systems of SACLOS missiles, aswell as laser designators, rangefinders and guidance systems, these can be seen when the tank is viewed from above.
       
      -----
       
      The heavier, far stronger pride of the ground forces.
       
      ZTZ-99 (A2 variant pictured.)
       
      Crew: 3
       
      Weight: 54-60 tonnes depending on variant
       
      Powerplant: 1,500 hp turbo charged liquid cooled diesel engine
       
      Speed: 80 km/h on roads, 60 km/h off road
       
      Range: 600km without external tanks.
       
      Armament: ZPT98 125mm L/52 autloaded gun with 8 rounds/minute rate of fire (some sources quote later variants at 11 rounds per minute), higher pressure tolerances, redesigned autoloader and other improvements, this allows it to fire improved ammunition such as far more deadly APFSDS then other 125mm autoloaded gun platforms in the PLA's inventory, it can still fire all other types of rounds aswell, W-85 12.7mm cupola machine gun, 7.62mm coaxial machine gun.
       
      Armor: While the exact thickness and composition isn't known, It's known from cutaway photos and some are pubically released information to have a hard spall liner as many other tanks these days, the actual armor composition itself are plates of high strength/toughness maraging steel sandwiching materials such as high hardness Aluminum oxides, aswell as layers of Graphene and unknown materials from there (likely something very dense), the boxes on the side of the turret and on the pike nose on the front are likely addon ceramic armor as opposed to ERA as originally believed and may be hollow to act as spaced armed, aside from the physical armor package, the tank also features ERA, NERA, and active defense systems that jam or alter the trajectory of various types of guided projectiles.
       

       
      So, this is the actual "elite" tank of the PLA to supplement the cheaper 96's, Originally it started out with a modest $2,500.000 production cost, however, as time grew on and they kept advancing it to the lastest standards of a top tier MBT, that sort of spiraled out of control a bit, coupled with the fact that the PLA ground forces don't get the same funding as the PLAAF and the PLAN, and the result was that, while the 99A2 has turned out to be a beast in it's own right, it simply isn't feasible price wise to give every tank crew a Type 99A2, however this is probably one of the most underrated 3rd generation MBTs as it's rarely talked about and theres a fuck ton of misinformation about it (mainly that it's a clone of the T-72/T-80 which is completely wrong) and well, it's goddamn pretty, and that counts for alot.

      Wherein I tackle the idea of hydrogen fuel cell technology in private vehicles.
       
      Buckle up.
       
      For the past few years, Hydrogen Fuelcell technology has been making the news in regards to personal transportation. Regardless of how long fuel cell technology has been used in the space industry, the media treated it like a futuristic Godsend for personal vehicles. I recall there being plans drawn up for refueling stations in California, even. But the Bear State is fond of making whatever promise they can to skim as much money from its people.
       
      See the High Speed rail fiasco.
       
      http://www.bloomberg.com/view/articles/2016-06-28/california-hits-the-brakes-on-high-speed-rail-fiasco
       
      When I first heard of hydrogen fuel cells being used in vehicles, I was too young and immature to have much of an opinion. Back then, I was still cruising around downtown and hanging out with Sturgeon to care about motor vehicle trends. Those nights were spent talking trash about HK products, doing blow through rolled up Benjamins, and dozens of questionably legal Polynesian women.
       
      I'll be approaching this issue regards to efficiency, safety, production, and storage of many elements. We'll first discuss what hydrogen is.
       

      https://en.wikipedia.org/wiki/Hydrogen
       
       
      The Wiki gives a ton of great information. Most of you will know the basics. It's a gas at STP, contains a single valence electron in it's 1s shell (“shell” or cloud of probability derived by shrodinger's blah blah blah Physical Chemistry nonsense, don't make me do that derivation again). It was first artificially made by a guy named Cavendish, and is found naturally as a diatomic molecule.
       
      This diatomic molecule also really likes to explode if it gets near an energy source. H2 combustion is well documented, and releases 286 kJ/Mol.
       
      In fact, it can undergo combustion at as low as 4% concentration with air. That's low.
       
      Hydrogen's low molecular weight makes it the lightest gas around. This was capitalized during the second to last turn of the century, where mighty Zeppelins pushed through the sky like herds of giant sky manatees.
       

      http://smhttp.41037.nexcesscdn.net/80153AD/magento/media/catalog/product/cache/1/thumbnail/750x/17f82f742ffe127f42dca9de82fb58b1/m/i/misc156_2.jpg
      Large enough to fit Colli-man's collection of miss-matched socks
       
      Germany loved these guys, and for a while they were all the rage in luxurious travel. Indeed, it was certainly the 20th century now! We had Airships, the Haber Process that was fueling an industrial revolution, and all of physics was completely solved! Thanks, Maxwell!
       
      (And then came the ultraviolet catastrophe, but that's another topic.)
       
      However, I mentioned above that hydrogen is extremely flammable at even very low concentrations within air. This fact really sunk the airship industry with a certain spectacular disaster.
       

      http://www.hipstersofthecoast.com/wp-content/uploads/2013/06/hindinburg-crashing-burning-640x420.jpg
      German Engineering, or Masonic Zion plot?
       
      It's easy to skip over this picture entirely. We've all seen it so many times (Unless you're one of my tutoring students, who look at me like I've got two heads when I mention it. “The hinda-what?”).
       
      But, this was the end of an era. Static charges ignited the hydrogen sacks that kept the big rigid frame afloat. And though we could have used Helium, a much more stable gas, the damage was done. No one would step foot near a rigid airship again.
       
      (Also our world's supply of Helium is finite and diminishing very very quickly. It would be wasted in airships. But again, another topic another time)
       
      Let's get back to the Hydrogen Fuelcell. What exactly is it, and how does it work?
       
      The basic model is shown below.
       

      https://upload.wikimedia.org/wikipedia/commons/thumb/6/63/Proton_Exchange_Fuel_Cell_Diagram.svg/2000px-Proton_Exchange_Fuel_Cell_Diagram.svg.png
       
      This diagram is for a Proton Exchange Fuel Cell. The proton here is simply a hydrogen that's been stripped of its single electron. A fuel cell works by having very special membranes carefully constructed to permit the passage of a positively charged ion, but not the negatively charged electron. This travels through another path, leading to a voltage across the cell. This voltage can be used to power any electrical device.
       
      This is an oversimplification of how the device works, but it's a start.
       
      The benefits of such a device include the shear efficiency that it can have. When properly insulated and owing to proper low-resistance connections, these devices are pushing out efficiencies twice that of internal combustion engines. Which, despite what many places attempt to sell you, are actually quite thermodynamically efficient. These proton based fuel cells have great cold-start characteristics and energy density. Their outputs can actually be very high.
       
      Indeed, these fuel cells are efficient at all power outputs as well. Their efficiency does not vary with flow of fuel source either.
       
      Their temperatures can be as low as 80 degrees C. However, usually they are kept above 100 degrees C because steam is far more manageable than liquid water byproduct.
       
      So with all of this information, you're probably wondering why haven't we started putting these into all sorts of places. This post is about personal vehicles, however, and I'll get right back to that.
       
      No. I disagree completely with them being used in personal vehicles.
       
      While I love fuel cells as a power device, their use in personal vehicles is greatly limited. One of the biggest engineering hurdles is the flammability and storage of pure hydrogen. Since hydrogen has such a low molecular weight, to obtain a large enough amount to power a personal vehicle would require a very high pressure container. If you remember back to your Chemistry classes in high school, you may remember the Ideal Gas Equation. Hydrogen is pretty close to an Ideal Gas. As close as you'll get, really. The Ideal Gas Law, in actual use, is only about 84% accurate when used to guess thermodynamic systems. For hydrogen it's much higher.
       
      PV=nRT, where n is the number of moles. Keeping everything but Pressure and number of moles the same, to increase the number of moles directly increases the pressure. And H2, having a molecular weight of 2 Grams per Mole, would require a ton of moles to get a decent amount of the gas.
       
      A very high pressure container of pure hydrogen gas in a vehicle that routinely travels at 70 mph. Which is statistically guaranteed to be in an accident in its lifespan.
       
      The Germans are watching this and going “Nein Nein Nein!”

      According to this nifty search, over 3,000 people die per day in the US due to vehicular collisions. Ouch. 
       
      However, this issue is the first to be solved. The introduction of Metal Hydrides have solved the storage issues. Metal Hydrides act as chemical sponges for Hydrogen gas (H2), binding the molecules inside their chemical structure. These metal hydrides are usually used as powders, where the hydrogen is then pushed through to store. To release the hydrogen, the metal hydride must be heated. The rate of diffusion is directly related to the temperature at which the metal hydride is heated, and thus the fuel rate into the fuel cell can be varied by varying the temperature of the metal hydride.
       
      Metal hydrides can absorb 2 to 10% H2 usually, but better compounds are being produced to increase the number.
       
      https://en.wikipedia.org/wiki/Metal_hydride_fuel_cell
       
      This is good, because it gives us a safe way to store hydrogen gas for fuel cells.
       
      This is bad, because the fuel delivery rate is much lower, and metal hydride fuel cells are, at their very best, 1/4th as powerful as their PEM brothers. At worst, they are 1/50th.
       
      But this is the best we can do in a vehicle. No one wants pressurized hydrogen canisters on the highways. Hell, most of the time you need special clearance and big signs to transport the stuff. And imagine the safety concerns for the EMTs and Paramedics during a car crash. Even if the tank isn't ruptured, no EMT or Paramedic would risk their lives until the wreckage was cleared.
       
      When I was going through my EMT training, they made it very clear that it doesn't matter if people are bleeding out in front of you. If you go in while it's still dangerous, you're only being a liability to your fellow EMTs, Firefighters, and police.
       
      But let's ignore the low power outputs of these MH Fuel Cells. What other issues do we have?
       
      Well, the fuel cell itself must be created using some very interesting techniques and materials. The biggest expense would be the platinum. Other catalysts are needed as well. As well as a very special proton-permeable membrane.
       
      To function, the membrane must conduct hydrogen ions (protons) but not electrons as this would in effect "short circuit" the fuel cell. The membrane must also not allow either gas to pass to the other side of the cell, a problem known as gas crossover. Finally, the membrane must be resistant to the reducing environment at the cathode as well as the harsh oxidative environment at the anode.
       
      This system includes electrodes, electrolyte, catalyst, and a porous gas diffusion layer. The rate of reaction will be dependent also on how quickly the water vapor product can diffuse through the porous material and out of the system. A system can have a lowered efficiency if the fuel cell is too dry or too wet. A balance must be met.
       
      And while yes, all of these situations can be worked around, it all comes at a heavy price. Currently we are using 30 grams of platinum in vehicle sized PEM fuel cells. This number will be going down once different catalysts are created, but the cost of these vehicles still pushes up to $50,000. The cost will go down, like any technology.
       
      I've yet to speak about where we obtain this hydrogen gas from. The easiest way to obtain hydrogen gas is via the electrolysis of water. H20 + An Electric Current → H2 + O2, essentially (it's not balanced, I know this.)
       
      But that electric current must be created as well. This usually comes from the electric grid, which is still, depending on the state, a majority coal-burning.
       
      Natural Gas reformation is another way to obtain Hydrogen gas, and is the most common way we currently use. It's the cheapest as well. Synthesis gas, a mixture of hydrogen, carbon monoxide, and a small amount of carbon dioxide, is created by reacting natural gas with high-temperature steam. The carbon monoxide is reacted with water to produce additional hydrogen.
       
      The other common ways are via fermentation of biofuel stocks (which is a long process without a great yield) or liquid reforming, which is really unfeasible in large quantities.
       
      The only way to obtain large amounts of hydrogen is via natural gas reformation, and that's still technically a fossil fuel source. So why were we going with hydrogen fuel cells again? To rid ourselves of dirty, dirty fossil fuel? Well shit.
       
      So to sum this up, the only way to safely use hydrogen as a fuel source in a moving vehicle would be by using metal hydrides, which require energy to access the stored hydrogen. This stored hydrogen flow rate is lower than standard PEMs, and results in a lower voltage, which in turn leads to a lower power output for the vehicle. More research and development must be done to find proper catalysts that can be made at a low cost, and production methods must be worked out to create the membranes more cheaply. All of this is held up by our hydrogen production systems.
       
      PEM fuel cell technology is awesome and I love it to death in many many situations. But vehicles isn't one of them.
       
      I may read about more advances in the near future that would change my opinion completely, but I would be surprised.
       
      Below I've added a problem out of my heat and mass transfer book (Incropera, 7th edition).

      Even though I'm relatively new to this forum, it did not take long at all for me to notice that here, I am in the company of many fellow petrolheads.
       
      Documenting the mildly interesting machines I encounter in my everyday life is something I like very much, and since I didn't see anyone here posting much about car spotting, I thought I'd make my own thread. So, if you have any pictures of interesting automotive finds, feel free to share them all right here. 
       
      To get the ball rolling, here's an imperfect (that racing seat looked really out of place, and there were some visible paint scratches) but still exquisite first-generation Mercury Cougar which I encountered this summer:
