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.
