It appears that Europe can work perfectly fine with rail along with places like China and India (I am aware of the population density differences, but LA isn't much different than Shanghai and they have maglev trains in Shangai), and it isn't impossible. Some people would need transportation to and from places, but like my fiancee' and I did, they should buy a Honda Insight Gas/Electric Hybrid (or Honda Civic 4-door Hybrid) and get +70mpg and only drive during the week when it is absolutely needed. The cars that want to be driven for fun or sport should only be allowed in the evenings and weekends. SUV's and pick-up trucks should be illegal (double when driven by 99.9% of women). So should cell-phone usage while the vehicle is in motion (for everyone). But, this will probably never happen, so what can you say? People believe they *deserve* those things in life. So, it is a matter of society, not technology or geological problems that need to be overcome before safe driving can be a reality.
Computers are not the end-all-be-all of automation. Especially in a society where such concepts as light rail fail to catch on. If you could build a car that can tell every single possible road condition including sublayer ice-under-snow conditions, soft shoulders, and other conditions and be able to detect every possible traffic hazard that could possibly happen farther than the human eye can see plus contain a near infinite amount of safe evasive maneuvers for each possible situation then maybe the system might work. I will never trust a computer system to know 100% of the time what the best possible situation is that can be taken under every circumstance. True, humans are generally much worse, but what about situations such as snow and/or ice on the road or blizzard/torrential wind and rain conditions? I live in a climate where it takes years of practice to safely drive under unpredicatable and slippery snow/ice conditions. Driving safe at these times, especially, is when you throw out textbook driving and drive on experience alone. The only problem is that people will become even *more* ignorant of how to drive properly and the society will get even more lazy than it already is. Why not simply build a nation-wide mass transit system across the country and make owning a vehicle almost monetarily impossible...sort of like Europe?
Whatever. Most of the posts here are from people who can't see the application from the paperwork. It looks good on paper. But, will it actually work in practice? That is yet to be seen.

That is one of the best sites for information on turbocharging a vehicle, but is very specific to Subaru engines. That is where I first began learning the most about Subaru engines. From there I am completely self-taught, and you can also know I am far beyond educationally qualfied enough to teach myself in this field, although I still ask questions from time to time. I am currently building my 2001 Subaru 2.5RS into a compelte replica 2001 Subaru WRX STi RA JDM and I currently race SCCA Autocross and soon SCCA ProRally.
The rest of the information I gained was from hundreds and hundreds and hundreds of hours over the past many years reading websites and books, searching the internet for information, and emailing tuning companies and fellow engine builders and tuners about questions I have. Another place I have gained a ton of information is from Amazon. Look for books written by Corky Bell and turbocharging tuning, espically Subaru and other turbo charging books.
The most important step to take beyond gaining the mechanical engineering knowledge of turbocharging and engine tuning (which should take you many years to fully understand and master) is to pick your engine and memorize every single fact and spec on that engine. Live that engine. Learn about engines in the same family. Learn about the engine families history. Find all of its limitations and strengths. Then, plan your turbo charging work from there. And after that, expand you knowledge to other engines, both turbo and non-turbo.
If you would like, let me know and I would be more than happy to share my personal knowledge with you. I am always very, very happy to share what I know. You can drop me an email at my personal email address and I will very happy to talk and mentor you the best that I can.
And just to point out, #1 isn't exactly true. The reliability of an engine block is very much a function of its ability to cool as much as it is the engines ability to handle thermal and physical stresses. And I would not recommend #3 as you really gain absolutely nothing in return for the chance at a completly destroyed engine. If you want bigger returns on performance, buy a lighter flywheel and leave the engine oil alone.

Interesting comment, 'boy racers'. Most SCCA and FIA racers, who are very much men, use reprogrammed ECU's in combination with engine building to produce large amounts of power and custom tunability. For example, a turbocharged engine is impossible to tune manually without either a very well programmed ECU or a system of very complicated manual controls (such as the independent throttle bodies and other similiar technology found in cars such as early Porsche turbo models), as evidenced by late 1970's and early 1980's turbocharged vehicles.
Your skewed perception of reality and your view that only 'boy racers' would want reprogrammed ECU's is completely wrong. It is true that many young boys and girls try to increase performance by only buying a chip, and they are wrong, but the art of reprogrammed ECU's is far beyond the needs and levels of only 16-18 year olds. No 16 year old can own an Audi S4 bi-turbo, but there are two guys I race with in my SCCA region who own Audi S4 bi-turbo's who are in their late 50's and who both have their Audi's ECU's reprogrammed.

It is only illegal to remove your catalytic converter where emissions testing is required by law. Where I live, there are no emissions testing. As a matter of fact, emissions testing isn't required in cities smaller than 150,000 people and even at 150,000 people and larger it has to be voted in and my city voted to not have emissions testing. Taking your catalytic converter off your vehicle is only a moral question, not a legal one in cases where emissions testing is not mandatory. For a mechanic, it is a question of legal liability, not a matter of whether it is legal to do it or not in a case by case basis.

You are not correct, nor is the article this story is based upon. For a normally aspirated engine, there are only a handful of ways to increase your engine's output:
1) Increased Compression 2) Increased Bore 3) Increased Stroke 4) Different Cam Profile 5) Change in Air/Fuel Map 6) Decrease in exhaust backpressure and increased intake flow 7) Increased maximum RPM
Of these options, only the A/F maps and a very, very, very small amount of timing advance can be controlled by the engine's computer alone (I will discuss #7 later).
To directly address one point, all modern engines contain automatic predetonation protection which automatically adjusts your engine's timing based on a combination of the octane of fuel used, humidity levels, altitude, temperature, O2 and predetonation sensors. Therefore, running 93 octane fuel will cause your timing to advance to its safest level on 93 octane for the conditions in which you are driving. For a naturally aspirated engine, that is about as good as you are going to get. No engine reprogramming is going to change that.
In case anyone is wondering why 'chipping' your engine is so popular for the normally aspirated crowd is because most maps are designed to increase power under 'partial throttle'. All performance tuning that gets spec'd is based on engine output at wide open throttle (WOT). At this point the engine is running in a condition called 'closed loop', meaning that the engine computer is not running the show, but is running one single A/F map and feeding gas, which is perfectly fine because at WOT that is what you want. At all other times, the engine is running in 'open loop' mode, which is where you will be driving 99.9% of the time. The 'open loop' A/F mapping is where performance improvements really come into play by adding an aftermarket 'chip'. You will not be gaining any real horsepower from your engine, but it will 'feel' faster and respond faster because, in reality, it is running A/F maps which will eliminate partial throttle fuel economy in exchange for mid-range engine output.
Now, before someone says BHP=(RPM*TORQUE)/5252 when I mention raising the RPM's to gain BHP, you need to know what you are talking about first. That equation is very, very simplified and doesn't take into account factors such as your fuel injectors duty cycles limitations, intake manifold limitations, engine spark limitations, fuel pump limitations, connecting rod force limitations, and intake and exhaust flow limitations. Almost all engines are designed for maximum BHP at redline and any more RPM's will either gain you nothing or will actually decrease BHP output.
The only factors that can increase real BHP output in a normally aspirated engine is a combination of ECU reprogramming and proper engine building. If you want to see real gains in BHP to the levels of 18+ BHP and 18+ ft.lb. torque, you would increase your intake volume, increase your exhaust volume which includes new exhaust headers, a high flow catalytic converter (because your flow is limited to the most restricted part in the system), and a 'catback' exhaust system, ported cylinder heads (if needed), and new camshafts. With that combination, a new ECU program can significantly improve the output of a normally aspirated engine.
For me, I am a turbocharged fanatic, and for me there are a ton of other options available to increase engine output. But, even for a forced induction system, you need to properly build your engine and complete system before any real, and safe gains, can be made.
And to make another quick point, engines which contain technology such as variable valve timing can take advantage of special tuning, because in that exact case, the ECU does have control over camshaft profiles. But, that is another discussion for another time and includes another set of interesting and inter-related factors.
It has as much to do with your processor as it has to do with the video card. I have a laptop with an AMD Athlon XP 2400+ and a Mobility Radeon 7000 IGP. I can play UT2004 in Direct 3D mode (DirectX 9.0) at 800x600 with full graphics turned on and every option I can find without a single frame rate drop or slowdown. About 5 seconds into the game and my CPU fan kicks into high speed mode, so it is definitely using a ton of processor power. It would be nice to play it at 1400x1050 resolution though (my everyday laptop resolution setting).

Wow, the shear ignorance in this entire article and book write-up is amazing. Not to truly upset anyone, but everyone here on Slashdot also appears to have a high school alegbra or entry level college mathematics background.
To start with, Mathematics is not just as human as poetry. Where do you get that idea? Yes, pure mathematics (which is my passion in life) is essentially pure thought. BUT, nothing in mathematics is just 'made up'. All mathematics is based on fundamental, logical axioms (truths), and if anything were to violate those axioms, or the completely logical conclusions drawn therefrom, it would not be mathematics. You can think of mathematics as a grand puzzle, with each discovered piece and each mathematical truth found spelling out a larger picture. You can create bogus logic, bogus mathematical problems but it does not make it true mathematics.
You are also confusing human representation with mathematics in your other statements. On a fundamental level, a law is a law, mathematically/physically/logically/universally. The universe is not ruled by human imagination (i.e. completely imaginary human created friend(s) as in religions) and therefore the system to understand our universe has to follow the same sets of rules as the universe (even rules involving possible pure chaos, as in some areas of quantum theory). Without mathematics, our universe and all that lies within it could only be understood on a physical observation level. Mathematics is the language of the universe, it is the language of physics.
For a slightly deeper explanation, let me explain that Mathematics does not involve physical representations as you were taught in HS and earlier. For example, the number 1 as opposed to a capital S to complete addition (which is a logical law) means that 1+1=2 is the same as S+S=* because the system is beyond the physical characters used to represent the logic. The logic would not be different in an alien society. The laws of the universe do not change, therefore the same logic would be implemented. Using a 1 or an S would make no difference.
There is sooooo much more, but just reading this story and people's posts makes me sad on a certain level. One of the oldest "truths" in the world...The person who is always least understood is not an artist, it is a mathematician.
No, I did not think this at all. In the efforts to achieve proper reception a writer will generally adjust his writing style to match the interests of his audience. I am certainly not in my teens nor early twenties, but I do find it entertaining to write M$, depending on my audience and personal affiliation with them.
He also mentioned in his write-up about the growing and soon to be exploding cultural gap between young, technically competent future in Iraq and the older, technically competent/incompetent. The software industry problems of today are because of the men and women in their 40's and 50's and older who applied an old business model to a new market with currently disasterous results (look at our current economic problems). I would say that starting a fresh technical revolution/culture in Iraq with the young Iraqi people who have the opporunity to use the mistakes of the past as lessons for the future is absolutely fantastic. Even if the use of the word Microsoft is referred to as M$ during technical or otherwise untechnical writing.
It is also difficult to take a site or person seriously when they talk about how the "Chicago Port Explosion" was the world's first "atomic explosion", yet next bothers to say how this is a fact.
It would be nice to see references for any of his stories, because as of now, I don't believe any of his writings directly as stated on his website.

Live that engine. Learn about engines in the same family. Learn about the engine families history. Find all of its limitations and strengths. Then, plan your turbo charging work from there. And after that, expand you knowledge to other engines, both turbo and non-turbo.
If you would like, let me know and I would be more than happy to share my personal knowledge with you. I am always very, very happy to share what I know. You can drop me an email at my personal email address and I will very happy to talk and mentor you the best that I can.
And just to point out, #1 isn't exactly true. The reliability of an engine block is very much a function of its ability to cool as much as it is the engines ability to handle thermal and physical stresses. And I would not recommend #3 as you really gain absolutely nothing in return for the chance at a completly destroyed engine. If you want bigger returns on performance, buy a lighter flywheel and leave the engine oil alone.
Talk to ya later.
And if you read what you post, which you apparently did not, these two sections and all sections related to them are for:
1) Reselling a vehicle
2) Dealerships
3) Repair shops
These rules do not apply to individuals who own their own vehicles and do not resell them with the catalytic converter removed.
Learn to properly read the law and then post a response.
Interesting comment, 'boy racers'. Most SCCA and FIA racers, who are very much men, use reprogrammed ECU's in combination with engine building to produce large amounts of power and custom tunability. For example, a turbocharged engine is impossible to tune manually without either a very well programmed ECU or a system of very complicated manual controls (such as the independent throttle bodies and other similiar technology found in cars such as early Porsche turbo models), as evidenced by late 1970's and early 1980's turbocharged vehicles.
Your skewed perception of reality and your view that only 'boy racers' would want reprogrammed ECU's is completely wrong. It is true that many young boys and girls try to increase performance by only buying a chip, and they are wrong, but the art of reprogrammed ECU's is far beyond the needs and levels of only 16-18 year olds. No 16 year old can own an Audi S4 bi-turbo, but there are two guys I race with in my SCCA region who own Audi S4 bi-turbo's who are in their late 50's and who both have their Audi's ECU's reprogrammed.
Please think before making comments in your posts such as the one you made in your post today.
It is only illegal to remove your catalytic converter where emissions testing is required by law. Where I live, there are no emissions testing. As a matter of fact, emissions testing isn't required in cities smaller than 150,000 people and even at 150,000 people and larger it has to be voted in and my city voted to not have emissions testing. Taking your catalytic converter off your vehicle is only a moral question, not a legal one in cases where emissions testing is not mandatory. For a mechanic, it is a question of legal liability, not a matter of whether it is legal to do it or not in a case by case basis.
You are not correct, nor is the article this story is based upon. For a normally aspirated engine, there are only a handful of ways to increase your engine's output:
1) Increased Compression
2) Increased Bore
3) Increased Stroke
4) Different Cam Profile
5) Change in Air/Fuel Map
6) Decrease in exhaust backpressure and increased intake flow
7) Increased maximum RPM
Of these options, only the A/F maps and a very, very, very small amount of timing advance can be controlled by the engine's computer alone (I will discuss #7 later).
To directly address one point, all modern engines contain automatic predetonation protection which automatically adjusts your engine's timing based on a combination of the octane of fuel used, humidity levels, altitude, temperature, O2 and predetonation sensors. Therefore, running 93 octane fuel will cause your timing to advance to its safest level on 93 octane for the conditions in which you are driving. For a naturally aspirated engine, that is about as good as you are going to get. No engine reprogramming is going to change that.
In case anyone is wondering why 'chipping' your engine is so popular for the normally aspirated crowd is because most maps are designed to increase power under 'partial throttle'. All performance tuning that gets spec'd is based on engine output at wide open throttle (WOT). At this point the engine is running in a condition called 'closed loop', meaning that the engine computer is not running the show, but is running one single A/F map and feeding gas, which is perfectly fine because at WOT that is what you want. At all other times, the engine is running in 'open loop' mode, which is where you will be driving 99.9% of the time. The 'open loop' A/F mapping is where performance improvements really come into play by adding an aftermarket 'chip'. You will not be gaining any real horsepower from your engine, but it will 'feel' faster and respond faster because, in reality, it is running A/F maps which will eliminate partial throttle fuel economy in exchange for mid-range engine output.
Now, before someone says BHP=(RPM*TORQUE)/5252 when I mention raising the RPM's to gain BHP, you need to know what you are talking about first. That equation is very, very simplified and doesn't take into account factors such as your fuel injectors duty cycles limitations, intake manifold limitations, engine spark limitations, fuel pump limitations, connecting rod force limitations, and intake and exhaust flow limitations. Almost all engines are designed for maximum BHP at redline and any more RPM's will either gain you nothing or will actually decrease BHP output.
The only factors that can increase real BHP output in a normally aspirated engine is a combination of ECU reprogramming and proper engine building. If you want to see real gains in BHP to the levels of 18+ BHP and 18+ ft.lb. torque, you would increase your intake volume, increase your exhaust volume which includes new exhaust headers, a high flow catalytic converter (because your flow is limited to the most restricted part in the system), and a 'catback' exhaust system, ported cylinder heads (if needed), and new camshafts. With that combination, a new ECU program can significantly improve the output of a normally aspirated engine.
For me, I am a turbocharged fanatic, and for me there are a ton of other options available to increase engine output. But, even for a forced induction system, you need to properly build your engine and complete system before any real, and safe gains, can be made.
And to make another quick point, engines which contain technology such as variable valve timing can take advantage of special tuning, because in that exact case, the ECU does have control over camshaft profiles. But, that is another discussion for another time and includes another set of interesting and inter-related factors.
It has as much to do with your processor as it has to do with the video card. I have a laptop with an AMD Athlon XP 2400+ and a Mobility Radeon 7000 IGP. I can play UT2004 in Direct 3D mode (DirectX 9.0) at 800x600 with full graphics turned on and every option I can find without a single frame rate drop or slowdown. About 5 seconds into the game and my CPU fan kicks into high speed mode, so it is definitely using a ton of processor power. It would be nice to play it at 1400x1050 resolution though (my everyday laptop resolution setting).
I absolutely agree with you.
To start with, Mathematics is not just as human as poetry. Where do you get that idea? Yes, pure mathematics (which is my passion in life) is essentially pure thought. BUT, nothing in mathematics is just 'made up'. All mathematics is based on fundamental, logical axioms (truths), and if anything were to violate those axioms, or the completely logical conclusions drawn therefrom, it would not be mathematics. You can think of mathematics as a grand puzzle, with each discovered piece and each mathematical truth found spelling out a larger picture. You can create bogus logic, bogus mathematical problems but it does not make it true mathematics.
You are also confusing human representation with mathematics in your other statements. On a fundamental level, a law is a law, mathematically/physically/logically/universally. The universe is not ruled by human imagination (i.e. completely imaginary human created friend(s) as in religions) and therefore the system to understand our universe has to follow the same sets of rules as the universe (even rules involving possible pure chaos, as in some areas of quantum theory). Without mathematics, our universe and all that lies within it could only be understood on a physical observation level. Mathematics is the language of the universe, it is the language of physics.
For a slightly deeper explanation, let me explain that Mathematics does not involve physical representations as you were taught in HS and earlier. For example, the number 1 as opposed to a capital S to complete addition (which is a logical law) means that 1+1=2 is the same as S+S=* because the system is beyond the physical characters used to represent the logic. The logic would not be different in an alien society. The laws of the universe do not change, therefore the same logic would be implemented. Using a 1 or an S would make no difference.
There is sooooo much more, but just reading this story and people's posts makes me sad on a certain level. One of the oldest "truths" in the world...The person who is always least understood is not an artist, it is a mathematician.
No, I did not think this at all. In the efforts to achieve proper reception a writer will generally adjust his writing style to match the interests of his audience. I am certainly not in my teens nor early twenties, but I do find it entertaining to write M$, depending on my audience and personal affiliation with them.
He also mentioned in his write-up about the growing and soon to be exploding cultural gap between young, technically competent future in Iraq and the older, technically competent/incompetent. The software industry problems of today are because of the men and women in their 40's and 50's and older who applied an old business model to a new market with currently disasterous results (look at our current economic problems). I would say that starting a fresh technical revolution/culture in Iraq with the young Iraqi people who have the opporunity to use the mistakes of the past as lessons for the future is absolutely fantastic. Even if the use of the word Microsoft is referred to as M$ during technical or otherwise untechnical writing.
It is also difficult to take a site or person seriously when they talk about how the "Chicago Port Explosion" was the world's first "atomic explosion", yet next bothers to say how this is a fact.
It would be nice to see references for any of his stories, because as of now, I don't believe any of his writings directly as stated on his website.
