What Is a Supercharger?

You might be aware of the different types of forced induction systems, but do you know how they function? Superchargers are similar to turbochargers except for the fact that they have different power supplies.

A supercharger is less efficient and uses power from the engine to give the car a massive amount of boost. This also means that more petrol is used. The upside to having a supercharger installed in your car is that you will not experience lag.

The supercharger is connected to a belt or pulley that connects to the engine. This whole system is connected to the crankshaft. It forces air into the combustion chamber by compressing air using turbines and screws.

There are two types of superchargers: Positive Displacement and Dynamic Compressor.

Positive Displacement

Roots Supercharger: this model uses a pair of meshing parts. Air gets trapped in the surrounding pockets so that it is forced from the intake side to the exhaust.
Lysholm Screw: this is also known as the Twin Screw Supercharger. It pulls air through the counter rotating worm gears.
Scroll Type: this system works by spinning in an orbit with a spiral shaped rotating lobe. This is the quieter and more efficient model.

Dynamic Compressor

Centrifugal: the exhaust turbine is replaced with a belt or chain to drive the compressors.
Axial Flow: This type of supercharger has a resemblance to jet engines. There are fan blades inside the unit that compresses the air within the housing.

The disadvantage of a supercharger is that it increases the pressure and temperatures of the engine which could cause overheating and serious wear. It is also a system that uses a lot of power.

The advantage of a supercharger is that is increases horsepower significantly without having to experience lag. They also have good power at a low RPM making them more powerful.

Although superchargers can make the drive from point A to point B more fun, they are significantly more costly than a turbocharger. Not only will it burn the fuel faster but the installation itself will cost more.

Tips to Sell Your Used Car

It is certainly a difficult job to sell out a used car at a good price. First of all, a lot of people suggest you different things and it becomes much complex. Secondly, the price is somewhat lesser than you expected which disappoints you. What you have to understand is that a lot of expectations can ruin a good deal for you. It is no way possible to get exact amount in return with profit. So, be a little considerate while talking to buyers. Don’t get fixed at a price which no one is going to pay for a used car. Here are some basic tips to help you through:

1. Visit a mechanic:

The very first thing to do after deciding on selling the car is indeed visiting a mechanic. Your car should look presentable for the customers. No one is going to pay for junk. Ask the mechanic to change the battery, fix the dents, change the tires, clean it thoroughly and if required, paint. The car should be in a good condition.

2. Set a price:

As discussed earlier, your price should not be too high for the customers. Do not expect too much for an old car when one can get a new one at the same price. Be realistic and fair while deciding a price. You can include your redecorating expenses in the price but don’t be adamant while dealing with the customers. A little bargain can also get you a fair deal.

3. Get your paperwork done:

Find all the documents of the car right from the purchase including even your servicing bills. It is required for the customer to realize that you kept the vehicle in good condition throughout the use. Include the receipts from mechanic, tires and battery receipt. A customer is definitely going to check these.

4. Meet with the car:

Don’t build castles in air by explaining your deal to them. Meet the customer at a place with the car. Don’t hesitate if you are confident for your vehicle and maintenance. Let them inspect. Let them ask queries and be polite. If possible, take them on a test drive, turn on the radio, show them the best of your vehicle.

5. The deal:

So, the customer has liked your car and is willing to purchase it. That’s a great news but don’t get lured. Research about the customer, his background and do not approve on installments. Don’t hand over the keys without getting the entire amount in your hands. There are always chances of fraud even.

The Basics of Recreational Towing

The first important thing, ensure that the truck you are using is fully capable of towing your caravan. Study the manufacturer’s guide on the maximum weight and make sure you are not exceeding the limits. A well-maintained, well-equipped, and safe towing vehicle should be the part of your caravan holiday.

Most of the people do not have the option to choose a truck that matches their van. Towing something with a truck is a technical task where you need to pay special attention to some technical aspects. For example, one simple rule is that the tow truck must be heavier than the caravan it is towing.

Four-wheel trucks are powerful, capable machines that can transport heavy objects. They can also tow large recreational vehicles. However, using off-road vehicles without going off the main road does not make sense. It is really a personal preference whether you want a manual or automatic transmission. In the past, people have always liked manual transmission. However, the automatic four-wheel drive should be an option for an off-road venture.

A safe towing operation begins with the right selection of a tow vehicle. If you carefully compare the manufacturer’s vehicle rating with that of your vehicle, you will know what you can accommodate in terms of size and weight. A wrong comparison can lead to alarming problems such as handling issues, failed hitches, and breakdowns.

When setting out on a venture, it is important to have a toolkit with all the necessary tools so that you can carry out minor repairs and replacements. A toolkit should have a hammer, pliers, screwdrivers, tow strap, shifter, spanner, and other tools that can help you out in an emergency situation.

Make sure you have an appropriate jack which is in a good working condition and that it fits both your vehicle and caravan. In addition, do not forget to inspect tires before hitting the road. Always carry a good spare tire for your vehicle as well as for the towing truck, especially when you have the plan to travel off the beaten track.

Every city or state has its own towing rules and regulations and you need to be in compliance with those regulations and laws. For example, safety chains are required by some cities. Safety chains should cross under the trailer tongue to stop the tongue from dropping to the road in a situation when the trailer separates from the tow truck.

You should always consult a dependable towing contractor if you do not have the sufficient experience or equipment to perform this activity yourself. You can get your recreational vehicle towed by a professional.
