Porsche: Setting the new standards in 2007
Some of the facts about Porsche: - Manufacturing the speed runners worldwide, the Porsche is the leading car manufacturer which is dealing with the new and latest models of the car. The latest models of Porsche are the streamlined models which are speeding on the roads. The high performance of the cars is due to the latest technology that had been introduced by the company. V10 engine is used in the vehicles which is delivering 600 hp. Besides this a layout of the brakes and clutch which is made up of the latest technology also supporting the car models in gaining the popularity. Car models of Porsche: - The models which are manufactured by the company are not just the simple racing car but these cars are as fast as the speed of light. According to the reviews from the company the car can go 0-62 mph in just a time of 3.9 seconds. And as the number of gears in the car the speed of the car goes on rising. The maximum speed when the car is switched to the 4th gear is above 143 mph and there are some models of Porsche which are providing the speed of 170 mph on 5th gear. And the most dashing fact is that the car is in the air on the 6th gear as its can provide race up to 700 rpm. The most expensive and the quickest model that had been manufactured by Porsche are around 484,000$. The main reasons behind the strong appeal of the car are some of the unparalleled features of these car models. These vehicles from Porsche are containing an engine of 5.7 liter which can generate 605 hp and is categorized in V10 engine. The engine of these car models is so strong because they are Porsche-patented engine and also the transmissions of these engines are made carbon reinforced plastic. Designing of the car models of Porsche: - In order to make the car a perfect racing car, the center of gravity of the car is lowered by belittling the diameter of the clutch. The aerodynamic package and race-bred suspension are secure and remain unchanged till the speed of 33 km/h is achieved. Also company is also following the strategy of using the light weight materials in the car. For example, magnesium is used for developing the significant wheels and the some of the sport seats which are exception are also developed. Porsche is known for producing the perfect racing sports cars which are spectacular is design and all the features of the transversally mounted transmission are added. Full care of the interiors as well as exteriors of the car is taken along with the air conditioning in these light weight car models.Know more about <a href=" http://www.gotengines.com">Used Engines </a> cheap<a href="http://www.gottransmissions.com"> Transmission Replacements </a> do visit GotEngines.com and GotTransmissions.com.

Demystifying The Tire Sidewall Code
So, you need new tires for your car or truck, but how do you know what to buy? What do all those alphanumeric codes printed on the tire sidewalls mean, anyway? If you’re in the market for new tires, you may simply want to replace your worn tires with exactly the same tire it came with. But you MAY want to consider an upgrade. If you know how to read the tire sidewalls, chock full of valuable information, you’ve got an advantage over most people and are prepared to make an informed decision. So let’s get underway! Tire Size Markings (example: P215/65R15 89H) Broken down: P = Passenger Other designations are LT = Light Truck T = Temporary (spare tire) 215 is the width (in millimeters) of the tire from sidewall to sidewall. A wider tire has more grip but the bad news is that you lose fuel economy, hear more noise and the tires don’t work as well in the rain. 65 is the aspect ratio The aspect ratio is the ratio of sidewall height to tire width. With regards to aspect ratio, the larger the number, the taller the tire sidewall. Tall (60-75) is great for a quiet ride but causes howling in turns. Short (35-55) is better for handling–more for sports cars. R indicates Radial. This means it is constructed with a series of support belts sideways under the tread. Other designations include B for Belted Bias and D for Diagonal Bias The standard, and what you’ll see most often, is R. 15 is the wheel (or rim) diameter, in inches. 89 is the load index H is the speed rating Speed ratings indicate the top speed under ideal conditions. Higher-rated tires are usually made of softer rubber and will have shorter UTQG tread life. Here are a few of the more common speed ratings: R= 106, S=112, T=118, U=124, H=130, V=149, W=168, Y=186. Along with this speed rating, you have a load index which indicates the approximate weight the tire can carry. Some of the more common load weights are as follows: 85 = 1,135 pounds, 86 = 1,168 pounds, 87 = 1,201 pounds, 88 = 1,235 pounds. UTQG Ratings Passenger car tires are accompanied by a UTQG Rating (Uniform Tire Quality Grading, mandated by the Federal Government) which rates the tread life of tires by looking at tread wear, traction and temperature resistance. The UTQG Rating is usually found opposite the tire size markings and will be in three separate ratings: treadwear, traction and temperature. The treadware grade standard is 100. A grade of 200 means the tread would wear twice as well as a tire graded 100. Traction grades run from AA to C, with AA being the highest grade and C meaning the tire brakes poorly on both wet concrete and wet asphalt. Temperature grades rate the tire’s resistance to and ability to dispel heat. Those grades are A (resists heat well), B (not as good as A) and C (passes minimum safety standards.) Keep in mind that heavy loads, under-inflation of the tires, and high speeds can all affect the tire temperature. You should note that these tire grades rate tires measured under controlled conditions. Factors such as driving habits, road conditions, climate, etc., are not considerations and may affect the actual performance of your tire. DOT DOT (Department of Transportation) indicates the tire is in compliance with applicable DOT safety standards. Next to DOT is an identification or serial number–codes that designate where and when the tire was produced. You’ll also find other information on the sidewall such as the type and composition of the tire, the maximum cold inflation (PSI) and maximum load in pounds. So as you can see, tires carry a huge amount of information. But it’s really not all that complicated once you learn to read the code.
