Adding a turbocharger to your car will give you one of the biggest increases in horsepower over any other engine modification. Nitrous oxide systems can rival the power performance, but not the durability and constant gains associated with a turbo system. Turbochargers can be tuned to give you any amount of boost between 0 and 24+psi of boost, depending on the size of the turbine. When you have any type of forced induction system like a turbocharger, you want to make sure that the engine is tuned to it. Below we will discuss the importance of the air fuel ratio. I will revisit this again, because premature detonation is a major cause of internal engine damage, and detonation can be caused by a very lean air fuel ratio. Turbo kits should be coupled with an ecu that is tuned to deliver more fuel than the factory settings, and the fuel delivered to the engine should be increased proportionally to the boost pressure. You also should add an air charge intercooler, which will reduce the intake charge air temperature. The air coming from the exhaust has been heated tremendously, and should be given the opportunity to cool before being re-entered into the system.

Beware of bolt on turbo kits. They in themselves are not the all in all for horsepower. You will have to match these with an intercooler and ecu to build a system that will have durability and performance. These bolt on kits are great for the experienced installers who can tune an engine correctly. The true power behind a turbo kit will be unleased with some tuning to the heads, the timing and fuel ratios, and the intake manifold. We will be discussing each of these in future post, beginning with the heads. The heads are where the power is made because they are a direct path to the combustion chamber, which is where the magic happens.

Internal combustion engines are “breathing” engines. That is to say, they draw in air and fuel for energy. This energy is realized as power when the air-fuel mixture is ignited in the combustion chamber. Afterward, the waste created by the combustion is expelled. All of this is typically accomplished in four strokes of the pistons. What a turbocharger does is to make the air-fuel mixture more combustible by fitting more air into the engine’s chambers which, in turn, creates more power and torque when the piston is forced downward by the resulting explosion. It accomplishes this task by condensing, or compressing, the air molecules so that the air the engine draws in is denser. Now, how it does that is the real story here.

A turbocharger is a way to force air into the engine. Hot exhaust gas powers the turbine wheel of the supercharger to make it rotate. That turbine wheel is connected by a shaft to a compressor wheel. As the turbine wheel spins faster and faster, it causes the compressor wheel to also spin quickly. The rotation of the compressor wheel pulls in ambient air and compresses it before pumping it into the engine’s chambers. As you may have guessed, the compressed air leaving the compressor wheel housing is very hot as a result of both compression and friction. That’s where a charge-air cooler (or “intercooler”) comes in. It reduces the temperature of the compressed air so that it is denser when it enters the chamber. The intercooler also helps to keep the temperature down in the combustion chamber. All together, the engine, turbocharger and charge-air cooler form what is known as a “charge-air system”. Some systems also include a tip turbine fan which draws air across the charge-air cooler to further reduce the temperature of the compressed air generated by the turbocharger.

The basic principal behind turbocharging is fairly simple, but a turbocharger very complex. Not only must the components within the turbocharger itself be precisely coordinated, but the turbocharger and the engine itself must also be exactly matched. If they’re not, engine inefficiency and even damage can be the results. That’s why it’s important to follow correct installation, operating and preventative maintenance procedures.

When adding a turbocharger or other forced induction system to an engine, you need to pay close attention to the air/fuel mixture ratio, as running lean can cause damaging detonation. Also pay attention to how much air the heads can efficiently flow. This is more difficult to measure or calculate, but much like the diameter of a straw can effect how much liquid it can draw, the heads will limit how much air they can flow through the system.

A turbine engine will give your model jet the most amount of realism. There are all type of turbine jets you can find readily available. But most turbine jet models are not for beginners! The mere price to buy one will probably cost you thousands of dollars, even a small gas turbine model can cost you over a thousand dollars. The fuel the engine requires is also very expensive. Even flying a turbine jet will require you to already have many hour’s worth of flight experience. You have to be prepared to invest quite a bit into it, but it has to be said that it is one of the most rewarding and enjoyable ways of flying, if you can afford it.

For example, the BAE Hawk is a plane that’s going to set you back over 8000 British pounds. This jet, however, has extraordinary flight abilities and made from extremely light, yet also high quality material. The wings and stabs are with a 100% honeycomb sandwich, and the fuselage has a multi-layer laminate with glass cloth that are used by real aircrafts.

The Hawk is considered to be quite a bit easier to fly that most turbine model jets, and if you’ve just started jet flying, then this jet is pretty well suited for you. The performance of the Hawk is very impressive, with speeds being able to top more than 200 km/h. The aircraft has a retractable landing gear, the majority of the preparations for installation have already been done. You’ll also be able to choose your own favorite custom finish as there are several different decal sets available in the kit.

The Rafale A model jet is extremely versatile. It is incredibly stable, yet at the same time it’s a fully aerobatic jet that will be able to perform all kinds of exotic maneuvers for you. Moves such as flat spins, cobra’s, and tail slides can be performed in flash. The jet is even capable of 3D style aerobics. The Rafale’s construction is relatively simple with well proven performance. If you already know how to fly a turbine jet, the Rafale A model jet is a great choice that will give you many hours of fun flying.

RC helicopters come in various forms and can be categorized in numerous ways whether it is by ability, power capacity, or size.

The most common form of a RC helicopter is a basic toy version which can be found in any toy store around. They can be used by almost anyone and are relatively inexpensive compared to the hobby grade RC helicopters. They do not operate the same as hobby grade ones but they are fun and a good way to introduce a young child to the hobby. Micro coaxial RC helicopters are sometimes still categorized with toy helicopters but much more sophisticated yet are still small in size. They are a great way to learn how to maneuver a RC helicopter because of their low cost and small size yet are still adored by avid hobbyists.

Larger electric RC helicopters have become more popular in recent years because of recent developments in batteries and their capacity. Batteries now last longer than in the past which makes using an electrically charged battery more feasible and easier. It is now possible to fly a helicopter longer because batteries now last longer and are actually lighter. Because the newer batteries provide more power than in the past it is possible for skilled hobbyists to maneuver while being quieter than before. Most RC helicopters sold in toy stores are electric but it is more common to see larger RC helis that are electrically powered then before.

Nitro powered remote controlled helicopters are powered by Nitro fuel. They are favored by hobbyists due to their relatively low price and unbelievable power. The Nitro engine in small yet is able to power larger more sophisticated aircraft. The engines used in Nitro RC helicopters are usually called ?glow engines? this is because they use a glow plug instead of a spark plug. They also use a particular fuel which is made up of methanol, oil, and nitro methane.

One more type of RC helicopter is the Gas powered RC helicopter. It is sometimes confused with Nitro powered helicopters but it is actually similar in mechanics but has a completely different engine. They use fuel which consists of regular gasoline and is mixed with two cycle oil. The engines are relatively larger when compared to the Nitro engine and it is also more expensive when compared to it as well.
