NASCAR Engines

NASCAR engines are like no other engines in the world.

Imagine what it must be like for a NASCAR engine to create huge amounts of horsepower and for many long hours at a time and without breaking down.

I don't think that most of us NASCAR fans really understand what a great piece of engineering the NASCAR engine is.

The fact is, NASCAR engines produce from 750 to 850 horsepower without using superchargers or turbochargers. How cool is that?

Personally, I just love the roar of a NASCAR engine.

Reason #1

As you might think, it all starts with the way the NASCAR engine is designed and engineered.

Because I'm just a simple man with simple needs, I always want an easy explanation as to how things work. And one of the reasons a NASCAR engine can produce so much power begins by making all the parts fit together perfectly.

If the parts are too big or too small, power is lost because of friction or pressure leakage.

A perfect fit is just the beginning.

Reason #2

Just picture in your mind for a moment a 358 cubic inch (5.87 Liter) engine.

A NASCAR engine this size isn't just made to run. It's made to operate for long periods and "dominate" the track. Compared to the size of your average everyday passenger street car, this engine is a "monster".

If you're going to compete, you have to go large.

Reason #3

Think of it this way.

If a person with larger lungs is running a race against a person with smaller lungs, chances are that the person with the largest lungs will win.

Why?

Because it's just like a NASCAR engine.

The more air packed into the cylinders the greater the energy that can be released and the faster the car will go.

Or put another way----more air, more power.

Reason #4

Unlike your family car, NASCAR engines intake and exhaust systems are tuned so that there is very little resistance to the gases flowing in the pipes.

Plus, there are no mufflers or catalytic converters to slow down the hot exhaust gases.

A good example is this.

When you have a chest cold, you can't breathe properly and you certainly don't feel right.

We can all agree that, when are lungs are clear of infection and congestion we have more energy and stamina.

NASCAR engines must let air flow "freely" to get the best results----just like you and me and the air in our lungs.

Does this make sense to you?

Reason #5

Your family car has a fuel injector.

NASCAR engines have carburetors, not fuel injectors, that let in large amounts of air and fuel.

Without these huge carburetors, NASCAR engines couldn't possibly create the power they need for today's sustained high speed races.

It's very simple with NASCAR engines.

More air in----more power out.

Reason #6

What a great idea this is for NASCAR engines.

By having high-intensity ignition systems that can be programmed, the timing of the "Spark" can be customized to produce the most possible power.

Or to put it another way that we can all understand---------

NASCAR engines get "more bang for the buck" right from the start.

Reason #7

Sustained high temperatures and speed can kill a NASCAR engine.

By making the alternators, coolant pumps, steering pumps and oil pumps designed to "tolerate" high temperatures and high speeds, NASCAR engines have become "smart".

They know how to handle the heat.

Now you know why NASCAR engines are so powerful.
