Featured Article: Car Sound Deadener:

What are sound deadeners and how can improve riding satisfaction?
From the name itself, you can probably tell what it does: it quiets the sound.
Sound deadeners usually consist of asphaltic mastic acoustal sheet material, which is capable of stopping vibrations such as those produced by sheet metal panels. These vibrations radiate noise, which of course, can be very annoying. Sound deadeners have a wide variety of applications, including vehicles and car parts, furniture, sinks, air conditioners, motor and transformer housings.
Among the newest addition to Auto Parts Discount's long list of top quality automotive parts are sound deadeners for several auto makes and models. Featured in the site are high quality Chevrolet sound deadeners, GMC sound deadeners, Ford sound deadeners and Dodge sound deadeners among others. These and thousands of other Ford parts, Chevrolet parts, GMC parts, Toyota parts, Honda parts, BMW parts, and Buick parts can be easily located at Auto Parts Discount's conveniently designed site.
In automotive application, sound deadeners are very useful in reducing road noise as well as noise produced by car parts as they function to make your vehicle work. High quality Chevrolet sound deadeners, GMC sound deadeners, Ford sound deadeners and Dodge sound deadeners are among the best sound deadeners you can find at Auto Parts Discount. They are made of highest quality materials to ensure your highest level of riding satisfaction through noise reduction without sacrificing performance. They are easy to install as well and are light so they don't add too much weight to the vehicle.
Ford sound deadeners, Chevy sound deadeners or GMC sound deadeners can be placed underneath the Ford carpet, the Chevrolet hood or GMC doors. They can also be found in the engine covers, floor panels and other interior components.
Noise is very destructive in driving. They may increase stress level and thus, and can cause accidents. Through sound deadeners, rattles and vibrations produced by some car parts as the vehicle cruises at high top highway speed or as it traverses rocky roads and uneven pavements can be eliminated or if not, significantly reduced.
Noise is not only produced by outside elements; interior parts may also produce noise and cause annoyance or distraction. Sound system components and other high-tech gadgets present in most modern vehicles are among those parts that produce vibrations; thus, the use of sound deadeners in vehicles with these features is necessary.
Only through parts such as the sound deadeners can we truly enjoy a comfortable ride inside a well-equipped and luxurious car. We can make clear phone conversations inside the car while it moves down the road, watch DVDs or play the CD player and listen to music without being distracted by road noises or rattling sounds. With the sound deadeners, we can truly relax inside the car as we wait till we get to our destination.

Top Three Performance Modifications for Your Car
So you're now bored of the modest amount of power you manage to squeeze out of your seemingly pathetic car and are looking to upgrade to a more fiery number, but how do you go about it?
Well, it largely depends on the type of engine - quite often manufacturers restrict the power from one of the engines in their current line up to provide the propulsion for one of their slightly cheaper or less sporty cars. This is usually a marketing decision to prevent the migration of customers from their more premium range to a cheaper car with the same performance, but more likely to ensure decent fuel economy and reduce emissions. In this case you probably have more chance of a significant power boost, than in a car which is already extracting full beans from the engine such as the turbocharged sub one-litre engine in the Smart. So read up on your car and find out whether the engine derivative is used elsewhere. If it is, you're in luck, but where do you start?
The most common methods to increase performance cheaply include:
1. Making it easier for the engine to take in air and get rid of waste gas
2. Modifying the electronic engine management
3. Reducing weight
1. Air intakes, exhausts and manifolds.
For the majority of cars, extracting every last horse from the engine isn't top priority for the manufacturer, reducing assembly costs is always high on the list. This includes making components with less complex curves such as those needed to allow a perfectly smooth flow of air into and out of the engine. The fluid dynamics of air as it enters and exits an engine is an extremely complex topic, which requires detailed and expensive computer modelling to ensure the optimum flow of air. Sure enough, less than perfect components are usually used in a cost saving exercise. Replacing such components with ones which aid the free flow of air is often a good way of ensuring the best efficiency of your engine with its current management settings. Do bear in mind that it's the free flow of air which is important - getting the fattest exhaust you can fit will probably compromise performance by not providing enough essential back pressure.
Key items to consider include air intake, air filter, intake manifold, exhaust manifold and exhaust pipe. K&N dominate the paper based filter market and
Pipercross do foam varieties, both companies will provide a solution for almost every car, and will even make one to fit if you know the dimensions of the pipes. These do need cleaning, usually at the service intervals, otherwise efficiency is reduced. Getting a free flowing air intake and manifold will further increase performance and the same is true for the exhaust end. The quicker the air can be expelled the less precious power is sapped forcing it out.
2. Modifying the engine management.
Almost all modern engines are now controlled by electronic engine management chips. This control almost every aspect of the engine, from the spark timing and fuel air mix to the rev limit and throttle response. When determining the factory spec all kinds of factors are considered, including fuel economy and emissions. Replacing or re-programming your chip can give instant performance gains, but usually compromises in other areas and can be expensive. Bear in mind once a chip is reprogrammed it can be expensive to reset it back to defaults.
3. Reducing weight
This may sound obvious, but reducing weight can be the easiest and most effective way of increasing performance. In real terms, the only figure that actually matters is the power to weight ratio. Reduce weight and you have the same effect as an increase in power and will also lead to more nimble handling. You'll be amazed how much weight can be lost from items such as rear seats, spare wheels, carpets, roof linings, sound deadening material....this list is extensive. This is only really an option if you are creating a dedicated track car, and you'll be equally amazed how noisy it can be without all this stuff inside!

Tips to prevent trunk rattling.?
I have two alpine type r twelves in my 2000 celica gt. They are wired to a 1300 watt amp so there is loads of power. There are so many vibrations and rattling inside and outside my car it's rediculous. I can't even tell where the noise is coming from because when it's that loud it's hard to determine. I know of dynamat and a few other sound deadener brands but does someone know any other techniques or something that prevents rattling, prehaps things that aren't even specifically made for cars but still work that are inexpensive. thankyou
try using the palm of your hand and hit panels in different ways to detect some of the rattling deadening spray or material for sure but one technique i use is home insulating expanding foam. use it in cracks and metal seams. this stuff is super sticky and can take a week to wear off so wear gloves.
spray into seams and way until it is not sticky about 5 min. use your fingers to press out the air and it will hold the Panel edges tight, dynamat before this and it will help vibrations from getting to the next Panel and if you take off panels i have used wood as a brace between inner metal and out.but one you get rid of some rattles you will hear others that were inaudible before.
