The resultant mixture may or not may be more efficient, but it will surely give more power.

Aroy, I am of the belief that denser air and high injection pressures leads to a fine atomization and higher the degree of atomization, higher the completeness of combustion. What is your view on this?

On the links provided, for every link that states one particular position (yours) you can find one that states the opposite (mine). I can show you a zillion billion links that concur with what I wrote. Does that make your or my view the correct one? Of course not.

Jeroen, Do not consider this an argument, These are just answers (and one question) that I have for you.
First and foremost, I am not desperate. If I sounded that way, may be I was wrong with usage of words.
All along, I have been talking about what (End result) a turbo a does and not how it does that (I might have touched base at certain instances).
For eg, when I talked about not enough exhaust gases, I meant the temperature and pressure of exhaust gases not enough to kick start the turbo. (automotive turbos, generally do not kick in at idle speeds) I was of the opinion that this is called a turbo lag.
I am confused here. A hypothetical question. Suppose a turbo is designed to kick in at 1500 RPM and the engine idles at 700 RPM. Now, you are driving at a slow pace (you do not need to cross 1300 RPM), in this case, you will still be pressing the accelerator (to go from idle to 1300 RPM) and the turbo will never going to kick in. Is this still called a turbo lag?
Again using a inter cooler as the name suggest is to cool the intake air (whose temperature has been increased due to compression) and the desired end result is increase in the density of air (which I had pointed out).
You are right with a zillion links and websites, As a market researcher it is my duty to filter good sites from the bad ones. The reason I had pasted the links, is that you can look at the content and decide on the worthiness of the website for yourself.
I again suggest you to put on some links to back your theories so that we can have a look at those sites. May be they would have dumbed it to my level.
By the way, times have changed and there are a bunch of people like me (and also in IT industry) who rely on WWW for information. Whether you take the information or not is at your own discretion. To me, the WWW has given me access to knowledge.
I also read some article sometime back, it had mention of a type of turbo using exhaust gas recirculation to harness the energy from the waste gases. Here the end result is increase in fuel efficiency and not increase in power.
Turbos running on electricity is new to me. Wont these put pressure on the batteries/electricals which have been strained all ready?
With BMW recommending people to drive their cars for at least 20 KM per week to maintain the life of the battery, I have reasons to believe that electric turbos will strain the system.
