Garrett Turbo

Simon Byholm asked:




In this article I’m going to discuss the properties of the diesel and gas engines, and compare them to each other. I’m specifically referring to their use in automobiles.

Looking at them from a distance both the gas and the diesel engine work in about the same way. A fuel made from refined crude oil is burned inside a cylinder and the hot expanding gasses forces the piston to move. The movement of the piston is then transferred to the wheels through crankshaft, gearbox and transmission.

It’s when we look at the engines a little closer that we start to notice that there are differences. Differences in gas mileage, smell, vibrations, price and expected age to name a few.

Ignition System

The gas engine has an ignition system with high voltages, wiring and spark plugs. The diesel does not need this, it compresses the fuel/air mixture until it’s so hot it ignites all by itself. In the gas engine it’s the spark plug that ignites the fuel-air mixture through a high voltage spark at the right time.

Another thing that separates the diesel from the gas engine is that gas engines adds the fuel vapor to the air in the intake manifold either through a carburetor or through fuel injection nozzles. The air/fuel mixture is then ****** into the cylinder to be burnt the next time the piston strikes.

The diesel on the other hand ***** clean air into the cylinder and then waits for the piston to compress the air as much as it will go. At this time when the air is compressed and hot enough to ignite the fuel, diesel is injected directly into the cylinder (or a small space connected to the cylinder) through high pressure nozzles. The fuel ignites instantly due to the high temperature in the cylinder.

The differences is fuel injection and ignition results in the diesel burning the fuel more efficiently than the gas engine. That’s why a diesel has a better gas mileage than it’s gas powered counterpart.

This is not to say that a diesel is better. It’s different, it has drawbacks too. Diesel engines usually is harder to start in cold and freezing weather. If you remember it was compressed hot air that ignited the fuel. When it’s too cold outside the air will never become hot enough to ignite the fuel, and the engine won’t run.

Cold Starting a Diesel

To handle this diesels have something called glow plugs for handling cold start situations. Electrical power from the accumulator is used to preheat the glow plugs inside the cylinders before the engine is started. This way the hot glow plugs ignite the fuel when the air is not hot enough to do it. Then when the engine starts it only takes a few seconds for the cylinders to get hot enough to ignite the fuel without help and the glow plugs are not needed again until the next cold start.

This is one of the nuisances of having a diesel in your car. The glowing takes from a couple of second to half a minute and can easily lead to stress when in a hurry. You just have to wait until it’s ready or the car won’t start. On the other hand if the engine is well done the glowing does not take long and you soon get accustomed to it.

Lets for a second look at the practical differences between the diesel and the gas engine. The diesel is large and loud, it emits black smoke when accelerating and is generally regarded as bad smelling by those not owning one. It also has a sturdier construction due to the higher pressures it must handle and thus can often go twice as many miles as a gas engine during it’s lifetime. The sturdier construction also makes it more expensive when first bought.

Features of The Gas Engine

* More quiet that the diesel

* Better acceleration and higher top speed

* Uses an Ignition System with Spark Plugs to Light The Fuel

* Adds fuel to the air before letting it into the cylinder

* Not as sturdy as a diesel. Lower price but breaks down faster

* Gas readily available everywhere

Features of The Diesel Engine

* Loud noise, sounds like a truck or agricultural machine

* Slow acceleration (get one with turbo charger, that helps)

* Lower top speeds but can easily reach the legal speed limit in most places

* Uses glow plugs to help the fuel ignite when the engine is cold

* Lets clean air into the cylinder and injects the fuel later

* Engine is simple and robust. Higher price but runs many miles

* Emits black smoke when loading it (like a quick acceleration)

* Easy to convert to using Eco fuel oils

If I where to give you advice on selecting either a gas or a diesel powered car I would probably tell you this: Get a diesel if you drive long trips and can live with the small nuisances of more noise and poor acceleration, get a gas powered car if you drive less than average or if you just want the comfort at any price.

ive been looking for a replacement turbo for my sisters car for a long time. i want to replace it because it leaks really bad. she goes through a quart of oil about once a month. the car still runs surprisingly but i don’t want her driving it like that. i want to say those b230f engines run between 14-17 psi of boost. the engine is a 2.3L L4 engine. those engines run really well when they work correctly. ive been looking at the garrett turbo’s. what would be a good turbo to install that would give it a little more kick. ide like to see around 240+ hp. it was stock at 165hp and 195 torque. boost kicked in around 2000 rpm. has anyone done this before. im lost when it comes to picking a turbo.

Lotus performance chips are designed in such a way that they are able to enhance the performance of your Lotus car no matter whether you have modified its engine or not. They work by providing additional information to its engine control computer. The only thing you must remember is to choose the right chip.

Lotus cars are manufactured in Britain. They are mainly sports cars. As all modern lotus cars are computer controlled there is possibility for performance modifications. It is easy to find the necessary components from car performance sites. As most Lotus cars are sports cars you can install racing spark plugs and racing chips to enhance the efficiency of these cars. These cars need to be in peak performance because they need to achieve high speeds.

Even in a Lotus sports car super charger should work perfectly to get the car to work at maximum efficiency. One of the ways to improve your super charger is to install a supercharger chip. Also you can go for an aftermarket air intake. When you have these modifications in place tuning fuel economy of your car is easy.  Installing a turbo charger is also a good option if you are concerned on fuel economy.

When you do modifications to the car its engine control computer will be burdened with more work. So, make things easier for the engine computer what you need to do is to install performance chips. They will keep on looking at different components of the engine. Whenever a setting needs to be changed the chips will do so to enable the engine to handle the situation better. So, it is good to install Lotus performance chips.

PerformanceChipTuning contains lots of information about different upgrade options as well as Lotus Performance Chips; you may visit them for more information!

About 50 VW Polo BlueMotion models will dominate this year’s ECHO awards, one of the most prestigious music awards in Germany given by an association of recording companies called the Deutsche Phono-Akademie.

During the awarding ceremony that will take place at the German capital city of Berlin, the VW Polo BlueMotion will function as the shuttle service for some of the local and international music artists, as well as guest visitors at the awarding ceremony. They will step on the VW floor mats and drive up to the red carpet aboard the VW Polo BlueMotion. This a way for the Wolfsburg-based car manufacturer to promote the advantages and the environmental attributes of the VW Polo BlueMotion including low fuel consumption and cleaner exhaust emissions. Moreover, the VW Polo BlueMotion also symbolizes environmental protection.

Stephan Grühsem, Head of Communications at Volkswagen AG said:

“We are confident that national and international guests at the ECHO award ceremony will welcome the opportunity to experience the advantages of the VW Polo BlueMotion – dynamics, low average fuel consumption and low emissions.”

Gerd Gebhardt, Executive Producer of ECHO 2007, added: “We are 100% behind this exemplary action. After all, the future belongs to economical and environmentally-friendly cars!”

A panic attack’s symptoms can exhibit themselves in many tactics but all can be desolating. If any of the symptoms I describe here appear familiar to you, there is a good chance you are suffering from panic fits or generalized anxiety disorder. But rest assured that these sensations you get are perfectly will not hurt you and are treatable with a good game plan!

Anxiety is an emotional imbalance that may be addressed with an endure ant and determined approach known as cognitive behavior care – the single most effective approach for conquering generalized anxiety disorder and their associated panic fit’s symptoms.

Common symptoms can be broken down into physical and mental classes. The physical symptoms may include racing heartbeat, sweating ( either hot sweats ), shaking, breathlessness and wooziness. You may also suffer from blushing, hot flushes, chills, bleaching ( pale cold skin ), muscle agony or an urge to urinate or defecate.

Mentally, as your panic fits transform to become what the medical profession call generalized agitation disorder, you may suffer from mental panic attacks symptoms. These include derealization where you feel ‘unreal’ or dreamy or you can feel beyond control or crazy.

You could also be affectedfrom depersonalization, where you lose the ability to emote yourself about anything.

A panic fit’s symptoms come about because of your physical and then mental reply to a hormone called adrenalin.

Adrenalin is a powerful hormone that excites the so-called fight or flight reply, an evolutionary system to increase your chances of survival when threatened – by either fighting or flying ; running away! This turbo-charger hormone has a massive physical impact on the body which are the symptoms you feel when you have a panic attack.

Your body has developed a ‘fight or flight’ hair trigger and this is why you have panic attacks. They’re false alarms that in themselves are safe but awfully unpleasant.

When you suffer from a panic fit, the symptoms are so unpleasant that you fear them going down again. This fear grows and becomes anxiety – continual worry. As time passes, you build up an unneeded capability to trigger the adrenalin surge awfully easily. And as you now know, the following panic attack’s symptoms are reason enough to be told how to beat the problem!

You do not need to live with panic attacks! You can be free from the panic and fear. The generalized agitation can be dissipated. But, it does take a little to work. The good news though is I have discovered a straightforward system that permits you to practically eliminate panic fits in a matter of seconds.

Is absolutely dazzling to eventually have my life back. To finally be in a position to live like a standard human and not have to worry about the panic attacks.

I can really go out and not need to worry about going through panic and fear. I don’t have the acrophobia and my other half is back the way it used to be. This is what I want for you and I would love to help you.

The first step is to actually know that the panic attacks will not hurt you. You can find it up in any medical website, or go ask your Doc. That would actually be the most preferred method. They will all tell you that panic attacks do not hurt you. They are a normal thing that happen to most women. But, people like us get every day anxiety and panic attacks becoming unbearable thing in our worlds. Things that we cannot control. Usually, this is controlled within our body. But, whenever the response to anxiety becomes overwhelmed it can sometimes get stuck in an open position. All you need to realize is that you can close it. It is possible to get a hold of your panic attacks and generalized anxiety!

Britt Eastwood asked:




There are so many products out there that seem to be just too good to be true and there are too many people out there that are more than willing to take advantage of another’s lack of knowledge. There are also sooo many out

there that are willing to play on peoples emotions, you know, the whole “you can have amazing results for practically nothing, and for only minutes a day at no cost to you”. We’ve all heard it before. So what makes diesel performance products, like a chip, or a cold air intake, or an exhaust any different. You might ask yourself, can adding something that small to my vehicle produce as great results as so many people tell me they do? Or will these items really pay for themselves in the form of added fuel economy, and reduced wear and tear on my vehicle? It is these questions about these products that I am going to address, and at the same time educate, because knowledge is power my friends.

If you were to modify a gas engine for performance, you would be required to install a different camshaft, bore out the cylinders to increase displacement, install high compression pistons and heads, increase fuel intake capability by installing a larger carburetor or injection system, adding a turbo charger or supercharger, adding a chip, and enlarging the exhaust system. But then you are still restricted by emission control systems. On the other hand, diesel trucks and cars are mostly turbo charged, and they already run at a higher compression ratio. Whereas on the gas vehicles you would have to make those changes. If you were to make those changes to a gas engine you would truly have a ground pounding beast, but would lose every day drive ability. The Diesels on the other hand are nice to drive around even with considerable modification. With a cold air intake, a chip, more efficient injectors, and a more open exhaust system, the diesels are still a nice ride, but when you really give it the gas, all heck breaks loose. There is enormous power without reducing drive ability.

Because of the nature of diesel engines they are designed from the factory to withstand much higher compression ratios than a gas engine. The diesel fuel combusts when it is compressed to a certain point whether or not there is optimum air. By simply shooting more fuel into the combustion chamber you can make more power. When you then improve the air ratio & timing of the fuel – you can make dramatic power and also improve engine efficiency. Gasoline

requires a spark to ignite it & must have the appropriate mixture of air to burn properly. There is also a lot more energy in a given amount of diesel fuel than in an equal amount of gasoline.

I will now break down the most popular modifications and explain their benefits.

1. A cold air intake is sealed away from the hot engine air, and is located where it can take in more air. Cold air intakes are equipped with a filter that can take in up to 300% more air. Cold air takes up less space. So there can be more air, more air helps to burn all the fuel, thus giving more power

and better fuel economy.

2. Chips make alterations to how the fuel is delivered to the engine, making it more efficient and more powerful.

3. A bigger exhaust or a mandrel bent exhaust (keeps the tube round, and the size constant) improves exhaust flow. Getting exhaust away from the engine is just as important in combustion as getting air into the engine. There are exhausts now that will even vacuum exhaust away from the engine, making it so that the engine doesn’t have to do that work.

All of these modifications add to the fuel economy of the diesel engine, and will over time actually pay for themselves in gas savings, and will continue for years after they are paid for to keep your money in your pocket. Diesels are the wave of the future and more and more economy vehicles are being

produced in diesel versions because they are capable of so much better economy.

Steven Taylor asked:


By Rob Sabbadin:

What I wanted to talk to you quickly about today is different turbo chargers and some of the things that people do with manifolds, dump pipes, different gaskets and washers that are used.

With the manifold here that we have in front of us, this manifold’s been HPC coated and the dump pipe has been wrapped.

The purpose of this is to actually help with the spool-up time of the turbo. If we maintain heat in the manifold it actually helps reduce the spool-up time. So, this whole manifold has been HPC coated, also, the dump-pipe has been heat wrapped.

This is also good for heat distribution in the engine bay because it’s maintaining the heat inside the manifold and not expelling the heat under the bonnet.

Also, with a turbo it’s very important when they are bolted up to a manifold, that all new gaskets and locking nuts are used. There can be a fair bit of vibration from an exhaust system attaching to a turbo which goes through the whole manifold. It’s very common for bolts to come loose.

In this turbo here, it’s had all new nuts and studs put on with locking tabs, along with locking nuts.

An important thing with turbos is a good quality turbo to manifold gasket. There are cheaper and higher quality gaskets available. The type of gaskets that we use are the same as EOM gaskets, which is a thicker gasket, which is three shims internally which are folded together.

These gaskets give a lot more “crush” and is a lot better with heat, and they will handle severe heat all of the time without failure.
