Honestly speaking, no one wants to be ticketed for speeding off on the expressways. For this very reason, drivers are always searching for a radar detector so that they can get a warning about the presence of a detector in advance. Drivers often go for the radar detector by Cobra because it helps them get off the hook of heavy fines by detecting the radar in advance and reducing the speed in time. But very often, biased reviews are published on these radars because the manufacturers would never want you to know about their minus points, and this is what makes the whole story bad.
An honest and fair analysis of the detector throws good amount of light on their features that bring out the quality and efficacy instead of the total valuation and price which are dependent on other variables. Thus, to aid the potential purchasers, some of the features are given below.
? Trust on the Independent Testing reports as they never manipulate their analysis of the product and almost always publish the right review.
? Utmost significance should be given on review of the new model. There are examples of people purchasing old models. The concerned authorities are also improvising their abilities to cut down the chances of interception of the signal because they are aware that the motorists are using a radar detector by Cobra. And this is precisely why, detectors that came out even 2 years earlier, may not be effective today.
? Checking on frequencies & modes for the detector is a ‘must’. This analysis should also include the frequencies in which the detector will function and also the fact whether it can diagnose radar in the POP mode or not. Even the frequencies which this device will intercept should be included in the review. This is crucial since different states use different frequencies and unless the detector can identify most of them, it may prove to be of little use.
? Several issues that make the radar really useful should be covered in the report on the reliability of detector, and so they are being discussed below.
(a) How frequently it gives bogus or false alarms that unnecessarily distract the attention of the motorist.
(b) The frequency of its failure to recognize the radar causing problems for the motorist.
(c) The frequency of the detection of radar after the offence has been done.
(d) The level to which it performs in the urban areas where the interference is very high.
(e) What happens in poor weather or during electric storms.
Radar Detector’s Countermeasures are often a topic of review and analysis. It may be wise to see if this feature about laser jamming or auto veiling is also available with the radar detector by Cobra.
People who are interested in getting great cars might want to check out sources other than the local auto dealers. One of these great sources that is gaining in popularity is public auto auction. These auctions usually take place in various cities and towns in the United States and are open to U.S Citizens and permanent residents who want to bid for cheap used vehicles. Since the government is responsible for these auctions, they usually don’t promote such events the way a private operator would, such as announcing when and where the auctions will be held. In the past this led to a situation where only a selected few were knowledgeable of the location where such auctions were taking place and took the oppurtunity to themselves.
Repossessed cars are a good idea if you want to save money when it comes to getting top value for your money in your next car deal. It is for this reason that you’ll most probably see owners of auto dealerships visiting such auctions in order to bid for vehicles that they will sell again for a considerable profit. The presence of such professional bidders at auctions is something that the average bidder is concerned of as they believe they may lose out but long time bidders know that they’re not a threat if the person bidding knows what they are doing.
To come out a winner in car auction is to make your best effort is to act like a professional bidder rather than an amateur. Luckily it doesn’t take much to do this, just solid decisions backed with critical thinking before bidding and setting limitations as to how far you can go in your spending already before the start of the auction. Most auctions will allow prospective bidders to inspect the cars beforehand in order to know what they are bidding for. For those who happen to know a car mechanic, you can bring one along when you want to inspect the vehicles before the event starts.
Another type of government car auctions is the increasingly popular police auto auction selling sites. Getting your used cop autos from car auctions is another way to go and with this process you can buy cheap autos at prices that make it seriously worth your while. You can acquire infos about when and where such auctions happen from websites that make this type of information available.
Fortunately while the majority of us are oblivious to these car autions where used autos are sold at budget prices, everything can be found on the internet and there are sites that provide great information for users that registered with them. People who want to take advantage of such information and locate the nearest auctions in their area, can use these sites in order to benefit from the great deals auto dealers are so keen to hide from everyone else.

When designing your engine for performance and winning races, you should at all times focus on getting the most air into your car as you can. The more air that can enter into the motor, the more fuel which can be combined with it and then ignited in order to create horsepower. The element of your engine which actually controls how much air is permitted to come in is called the throttle body. Go to emission control for more information.
The throttle body is pretty easy to spot. It is the circular or rectangular opening on top of, or on the side of the intake which can have one or more flat butterfly valves covering the opening. When you press down on the gas pedal with your foot, what you are really doing is opening up this valve on the throttle body to let more air in which in turn sucks more fuel into the engine.
Since more air equals more horsepower, does that mean that a bigger throttle body which lets in more air means you will be able to increase your engines performance? In general, yes. A larger throttle body will suck in more air, and as long as your engine is capable of keeping up with the fuel demand then you should see a horsepower increase. Performance-oriented throttle bodies are also often better able to provide precise control over how much air is entering, giving you a more accurate throttle. However, keep in mind that an engine is a system, and it should be treated that way. Bolt-on components like throttle bodies can help to improve your performance, but they work much better when matched with the proper valves, exhaust system and overall tuning.
Refer to emission control for more information.
For the ultimate in performance, the key is not to go bigger, but actually add supplementary throttle bodies to your intake. In fact, you can even add a throttle body for each cylinder in your engine. These are called individual throttle bodies, and together with a special intake they can provide a direct path to air for every cylinder individually. Individual throttle bodies are the ultimate in performance for this type of modification, but their implementation is fairly complicated.
Getting each of the throttle bodies to open at exactly the right time in tune with each other is a difficult proposition. Not only that, but out on the street potholes, speed bumps and just general road roughness can provide enough vibration to seriously interfere with the correct calibration of these throttle bodies. It is usually a better idea to reserve the use of ITBs for cars that will only be used on the track unless of course, you have the time and energy to devote to making sure that these throttle bodies stay in tune on your daily driver.
Whichever route you decide to go, whether ITB or larger single or dual throttle bodies, you need to make sure that you arent overloading your engines capacity. If you cant get enough fuel into your engine to make use of the extra air, you might actually decrease your performance. A larger fuel pump and fuel injectors with a higher flow rate can help to make sure that your new throttle body solution gives you the horsepower gains you are looking for.
