Tuning a Rc Nitro Engine for Optimal Power - a Guide for Beginners

When I first started racing Gas Powered RC cars, I used to struggle to get the engine into tune, while I was able to get the engine to start on a dime and it used to run fine for almost an entire fuel tank, it always seemed to over-heat near the end of the run. After many hours out on the track I can now finally say that I've got it down, tuning for me is now a 5 minute operation before I take my RC car out, and once it's dialed in I only need to adjust one needle a fraction of a turn to get it back to it's optimal settings.

I assume that your understand the basics of a RC Nitro Engine and how it works, if not please see my other articles which you can find on my website, see the resource box for details.

The Idle Screw
I always start with the idle screw, I adjust it so that the car will idle high when I'm first dialing in the engine. Once I get the engine up to temperature and with a tube that can keep it running without stalling I slowly adjust the idle down to the point where it's about to stall, then I turn it back about 1/4 to 1/2 turn depending on the temperature. If your car stalls often it can be worth while increasing the idle to prevent this, it's only a temporary fix while you sort out the other tuning issue, but it helps keep frustration levels down.

Low Speed Needle.
One of the great debates is which needle to adjust first, if your carburetor only has one needle adjustment screw then it's not a problem, but if like most glow engines you have two you need to decide which to tune first. I always start with the low speed needle, this is because when you adjust the low speed needle you change the high speed needle. Once the low speed needle is dialed in you shouldn't have to adjust it again. Make sure you keep it slightly on the rich side, when you RC Car idles the combustion chamber should start to fill up with fuel, this helps keep it cool. After a while the engine will stall, by measuring this you can tell if it should be richer or leaner. A good time is about 30 - 60 seconds before it stalls. The RC Car should pull off quickly from a standing start and should not bog down or flame out when you apply full throttle.

High Speed Needle.
Once you have your low speed adjustment needle dialed in it's time to start getting the power out of the RC engine. This is done with the high speed needle, which adjusts the air to fuel mixture of the engine while it as high RPM (about 40% and up). Keep an eye on the trail of smoke as this is your first clue about the tune. You want to have a lot of smoke coming out of the engine at all RPM, if at some point there is little or no smoke then you are running too lean.

Hints, Tips and Tricks
* Turn the needle clockwise to lean out and counter-clockwise to richen the mixture.
* A lot of smoke means you tune is rich.
* The sound can tell you about your tune.
* Reading your glow plug after a run will tell you a lot about your tune.
* Make sure to run your engine on the rich side, this will extend it's life.
* A lean engine will always put out more power, but it will shorten the life of your engine.
* Temperature, air pressure and humidity play if big part in the tune, different days will need different settings.

Auto Performance Tuning, Give More Power To Your Car

Every major and minor working part of your car can be fined-tuned to increase speed, smoothness, and drivability. Let's explore the key areas of performance tuning and see how each can contribute to better driving.

Fine Engine Tuning

There are several key areas of tuning that can help give your car or truck an engine boost. One is to install a performance chip. A performance chip can be fitted in engines with fuel injection and an ECU, or Electronic Control Unit.

With a performance chip, non-turbo engines often result in about a 10 percent power boost while turbo engines often see an increase of 25 to 30 horsepower!

Engines also see a power boost with a performance cam, which can be fitted by an experienced mechanic or a really knowledgeable homemechanic. Cams of about 270 degrees can boost the engine up to an extra 12 horsepower.

A power boost valve can also be installed to replace the fuel pressure regulator, which is located in the return fuel line.

Brake Performance Tuning

Be sure to enhance your braking power before increasing power in your automobile. Brakes are very important for your performance and safety although they are not considered performance-enhancing features.

A simple way to improve braking is to install performance pads and fix performance discs. Performance brake pads enhance braking power and can withstand much higher temperatures than regular brake pads.

Air Filters and Tuning

Probably one of the easiest tune-up tasks is to replace the air filters or the air filter element in a performance air filter. If you have a fuel-injected car, you can also enhance airflow by removing the original airbox, which contains the air filter and hoses and then replacing it with an induction kit.

The kit is a cone filter that can be attached directly to the air flow meter, thus, creating a more directed, uninterrupted airflow to the engine. More air means better engine performance.

Exhaust Enhancement

With exhausts, you're not focusing on what's going into the engine, but what's coming out. There are performance exhausts that minimize pressure restrictions for fumes that are on their way out.

Hint: Replace the factory-made exhaust manifold with an aftermarket brand that is tuned to boost power.

A Better Ride with Enhanced Suspension

Suspension is another key car tuning area that often goes unnoticed. Lowering springs can be fitted to get a better look and feel for the car. Handling is improved because the springs reduce roll when taking corners. Also, the tires will have improved contact with the road.

These springs might feel like standard springs when driving over small bumps in the road; however, when cornering hard they stiffen and reduce roll. This gives comfort and improved handling. Shock absorbers and up-rated bushes also enhance suspension.

Abundant Tuning Supplies
If you have trouble finding the performance tuning products you need, use the Internet to locate thousands of tuning products at great prices. You can find auto parts and supplies for car tuning, truck tuning, SUV tuning, and more.

Also, browse through top brand name products known for their durability and performance-enhancing qualities. There are Sniper tuning products, Diablo tuning products, and many others.
Give special attention to these key areas during your next performancetuning to enjoy maximum results.

Maximizing Your Engine, Performance Tuning

Stuffing more horses into your engine used to take countless hours, cost a ridiculous wad of cash in parts, and usually resulted in the busting of several knuckles.

Thankfully, with today's computer-controlled vehicles tuning is about as easy as playing Pong.

If you've seen the TV shows geared at getting every droplet of power out of a classic vehicle, you know they spend the entire show with a load of time-lapsed video of them tearing the engine apart to put in extremely technical and wildly expensive parts.

When it's all done, they crank up the dyno and get giddy over the 3 horsepower gain realized after roughly 4 hours of work.

That's not exactly how most would want to spend their weekend, and all for a measly 3hp.

Of course, there's quite a bit to be said for those computer-free classics that you can have full control over. However, when it comes to getting more power in no time and without having to tear up your hands or throwing piles of cash on hard-to-find parts, a computer-controlled vehicle has a distinct advantage.

The good news is, you're probably driving a computer-controlled vehicle, like most sold over the last quarter century. This makes tuning much easier, because a set of programs determines how your engine performs.

Simply replace your engine's stock programming with some that's geared toward performance and you'll discover power gains almost instantly.

Just how can you get these power gains in minutes? The answer is easy, with a power programmer or performance chip, like those made by Hypertech or DiabloSport.

These power programmers are designed to hold performance programs created and tested by the pros. It's so straightforward a caveman could do it.

Just plug it into the OBD-II port beneath your steering column, enter a few simple yes or no commands to adjust how you want the engine to perform, upload the new programming, and you're ready to rock with 25 or more horsepower. For most folks, this will take a maximum of 10 minutes to complete.

There are a few drivers out there who want the extra power, but are apprehensive of using this sort of tuning method.Their concern is that how can so much power be gain so fast, when the guys on tube spend hours and only add a few horsepower. But the skeptics can rest easy. Modern automakers simply down-tune their cars for the general population.

Engines are setup to work the same for performance enthusiasts as they do for octogenarians who believe going over 40 mph is breakneck speed. You don't fall into the later, nor are you a soccer mom unconcerned about performance, you demand it.

Performance programmers aren't average settings and that makes them a perfect match for you.

And, you don't have to worry about warranties. The companies that make programmers take safety into account with their settings and further they often give you ways to return to stock settings for service visits at the dealership.

What's more, as with all performance mods, you'll be protected by federal law. It basically states that your vehicle's warranty cannot be voided by performance parts unless they can be proven as the source of the breakdown.

So, there's no good reason to wait if you're look to easily tap into the true potential sitting under your hood.

Prepare Your Car for Winter: Four Things to Do Now

VERY USEFULL INFORMATIONS

If you have never lived in a cold climate, you probably haven't had to deal with driving and handling a car in snowy conditions. There is a lot of preparation that needs to be done before you can drive safely through the winter. Just as you change your wardrobe for winter, your car needs a winter wardrobe. Use the following steps to help ensure your car operates safely during the winter.

Preparing your car for winter breaks down into two categories: regular car maintenance and specialty items to deal with inclement weather. Regular car maintenance includes things that you do to your car year round. You need to make sure that these maintenance tasks get done before the weather starts to change so you can make sure that your car is running at its optimum level.

Before the winter starts, you should get your car's routine maintenance up to date. Getting your oil changed and your brakes fixed are essential in preparing your car for winter. Roads can be dangerous after the first snowfall. If you opt to go for snow tires, you should get them installed several weeks before winter hits. Snow tires aren't always necessary but they are a good idea if you are going to be driving in a place that experiences a lot of snowfall. Even if you don't need snow tires, check to make sure that your tires are in good enough shape to handle the wintry conditions.Test out your windshield wipers before the first rain or snowfall. Be sure the wipers don't just smear water across your windshield. Windshield wipers that work improperly can severely reduce your visibility and put you at risk for getting into an accident. Replace your windshield wipers and take a look at the special winter windshield wipers that are available on the market today. If you live in an area where you frequently experience snowfall, this may be a good option. While you're at it, make sure that your windshield wiper fluid container is filled, and put an extra gallon on fluid in your trunk.

The next part of car preparation is gathering together the supplies that you'll need to get your car running when the weather is bad. These supplies should be kept in two spaces: your garage and in your car. For your garage, you'll need a shovel, a small broom and some de-icing spray. These are necessary in order to free your car from any heavy snowfall that occurred the night before. You may also find an ice scraper handy.

For your car, you should carry an additional ice scraper and some de-icing spray to use if you have to park outside during work hours. These items should be kept with a winter emergency kit that is stored in the trunk of your car. In addition to the scraper and spray, you should store a blanket, some dry snacks, first-aid supplies and bottled water. If you're ever stuck in a snowstorm, these items will help you survive.While driving during the wintertime certainly isn't something that you should worry about, you should take the steps necessary to prepare your car for the coming months. Get your car tuned up and stocked with emergency supplies and you'll be ready to take what ever the winter weather throws your way.

Giving Your Car a Thorough Auto Tuning ( GOOD TIPS )

Auto tuning is really important if you want to keep your car in its tip-top shape. This will also improve your car's handling as well as raise your car's value.

If you own a car, you probably know the importance of auto tuning. There are people who do auto tuning as a hobby and there are people who actually do this for a living. When you subject your car to an auto tuning, you basically give someone the right to modify it, usually to improve its performance or its handling.

Some people also have their cars tuned to fit their style. This is not as hard as you would think and all it takes is a little knowledge and skill.Understanding Auto Tuning
Cars are pretty much generic. Yes, they can be worth millions of dollars but they are pretty much generic. They are not made specifically to suit your style or your needs. This is why there are people who have their cars tuned.

There are really many ways of tuning a car. You can have it sprayed with a different color. Does your car have a boring blue paintjob? Would you like to have it painted black with lightning streaks of red on the sides? You can place accessories that maybe unnecessary but could make your car look good. You could add in spoilers, side skirts, air vents, double exhausts and bumpers. You can spray symbols or other designs as well.

One of the many popular tune-ups that cars usually have is the engine tune up.

Aside from tuning up the engine, you can also do other things related to your engine's performance. You can adjust your fuel economy or you can modify your car's RPM. All these things are done not only to improve the aesthetic value of your car, but also to allow easier handling and better comfort.
These days, auto tuning is not something that is taken lightly. In fact, there are events that you can join. People actually hold events for car owners to meet and compete. The judges will usually pick out the car with the best tuning. You can even win prizes for having the best auto tuning.

The Auto Tuning Your Car Needs

It is advisable that your car should get a tune up every 30,000 miles. This is a good way to prevent permanent damage to your car. A thorough auto tuning includes replacement of fuel filter. Sparkplugs and sparkplug wires, distributor cap and rotor, valves, belts, air filter and positive crankcase ventilation. You may want to check your fluid levels as well. If your transmission or brake needs some fluids, provide it with some. Give your battery a thorough cleaning as well. While you are at it, check your brakes, lights, wiper blades and other car gauges.

Auto tuning is important. This prevents damage to your car. This allows easy handling as well. With regular auto tuning, you will ensure that you will always have a clean and trustworthy ride.

Eco-tuning: Saving More Gas Without Sacrificing Performance

Eco-tuning is very useful for car owners who travel long distances regularly as it will help them save gas more. Plus, using an eco-tuned vehicle will give the car owner the benefit of not changing gears too often. This will result in more gas being saved every time a car owner is travelling for long distances.

There are a lot of auto shops out there that specialize in eco-tuning vehicles. These various shops can help any car owner achieve their desired tuning for their respective cars. In addition, these shops can provide car owners with gas saving tips to maximize the use of their eco-tuned car. In this way, the car owner can drive their car ideally without worrying about the rising cost of fuel. Plus, their fuel consumption is bound to decrease by 20% with the help of eco-tuning. This will result in a better performance from the vehicle and a lessened dependence on fuel. Just make sure the vehicle is suitable for eco-tuning to avoid any complications.

How to Increase Your Sports Cars Fuel Efficiency

One of the blights of owning a flashy sports car is the large amount of gasoline they consume. Unlike the larger, bulky vehicles that consume a lot of gas due to their size, sports cars usually burn a lot of gas due to fast accelerations and all around fast driving. With the price of gas going up all over the country, the fun of owning a sports car is quickly diminished when it comes time to visit the pump. In order to reduce a bit of the hurt that these sports cars and do to your wallet, keep these fuel tips in mind.

The first thing that you can do in order to save money at the pump is to simply cut down on your driving. You can try car pooling or taking public transportation when available. This way you can save driving your sports car to when you really enjoy it, not for boring commutes. For when you are driving the car, remember to keep it as light as possible. The fewer heavy objects and people that are in your car when you are driving, the less expensive your fuel bills will be.



One of the more prominent reasons why sports cars guzzle so much fuel is due to their fast acceleration. It is a lot of fun to be able to go from 0 to 60 in just a few seconds, but think about what it is doing to your cars gas mileage. Keep your foot lightly on the gas pedal while accelerating; there is no need to get off to a lighting fast start all of the time. Another thing that guzzles gas is driving too fast. Driving fast is what makes sports cars fun, but the gas bills that result from it are anything but. In order to get the best fuel efficiency, drive in fifth gear at 40 to 55 miles per hour when possible.



The next thing that you can do in order to increase your sports cars fuel efficiency is to keep your tires inflated. If you are unsure as to how much air pressure you should have in your tires, consult your vehicles doorjamb, or owners manual. The number on the tires themselves may be inaccurate for your particular vehicle.

During the summertime, a debate that often occurs concerns the best way to save on gas, to either open the windows or use the air conditioning. While there is no simple answer, it all depends on a few factors. When driving at faster speeds, it is usually better to have the windows closed in order to prevent drag. When you first enter your vehicle, if it is very hot, it is better to drive around at relatively slow speeds with the windows down. This way you can get rid of the hot air quickly without overworking your air conditioning. If you own a convertible sports car, you will burn less fuel if you keep your top up.
