NITRO IN TYRES FOR YOUR SUBARU IMPREZA WRX STI CARS?



NITROGEN GAS IN TYRES ???

Do you know how many revolutions a tyre makes on a F1 car as it races around a circuit? How does 3000 sound to you?

Any steering input from the driver is transmitted to the road via these thin strips of rubber. At speeds of up to 360kph, one better hope that the tyres do not rupture or punture otherwise it will result in a hugh accident! This constant risk means that it is essential to make tyres as safe as possible and one way to do this is put NITROGEN in them.

Nitrogen is a very unreactive gas. if you fill a tyre with dry nitrogen gas, it is possible to predict how much it will expand as the tyre heats up from friction with the road.

Air on the other hand is unpredicatable. While its composition of nitrogen and oxygen is always the same, the amount of water which makes the expansion of air within the tyre very unpredictable. Using nitrogen gas in tyres will ensure that this expansion is more predictable and consistent.

If the pressure in a tyre is too high or too low, the steering and handling characteristic of the car will change invariably. For example if the pressure is too high, there will be loss of steering feel as the steering will feel lighter and all round grip will be reduced due to the reduced tyre/road contact surface.The tyre will also wear prematurely in the middle.

Too low a pressure and the steering will feel excessively heavy and this results in sluggish steering response. The tyre will also wear prematyrely at the sides.

Another important advantage is that nitrogen expands less than oxygen when heated which means that there is less chance of the tyre exploding during a fire. Tyres can explode with the force of a dynamite detonation and this increases the risk already faced by the driver and passengers. Water present in the air oxidises the rubber in tyres causing them to corrode. Over long periods, gas also diffuse out of the tiny pores found in rubber tyres. A nitrogen molecule is larger than an oxygen molecule. Therefore, nitrogen gas leaks out of the tyres three times slower than air.

A tyre filled with nitrogen will maintain the correct tyre pressure longer and this means that a tyre will maintain performance longer as a result of slower wear.



All in all, advantages of using nitrogen gas in passenger car and race car tyres outweigh the only disadvantages, which are price and availability

Exhaust For Subaru Impreza WRX STI 2003-2004 Car

Image
The HKS Carbon-Ti catback exhausts are exclusive Special Edition HKS Hi-Power catback exhaust systems . Also referred to as the HKS Carbon Titanium Hi-Power catback exhaust, these exclusive versions of the HKS Hi-Power catback exhaust consist of a carbon-fiber wrapped muffler shell, titanium tip, and polished SUS304 stainless steel piping for a stylish and aggressive look. Each HKS Carbon-Ti catback exhaust looks as good as it performs. Inspired by GT racing in Japan, HKS developed its Carbon-Ti catback exhaust system with features found on racing exhaust systems. The HKS Carbon-Ti catback exhaust series incorporates a race inspired offset muffler and piping design, eliminating unnecessary bends for the straightest exhaust path. This less restrictive design allows the HKS Carbon-Ti catback exhaust to have greater exhaust flow and less back-flow pressure, enhancing higher-PRM power gains. The HKS Carbon-Ti catback exhaust system can be used for both turbocharged and naturally aspirated

Subaru's Car Intake System Design

Subaru's Car Intake System Design The following is an opinion on why different year model Subaru's react differently to modifications to their intake system . Primarily we're focusing on the late model Subarus which used either an air-flow system (up to 1999) or the speed-density system (2000+) in the North American market. Before we discuss the technical details of the Subaru Intake System, lets first get familiar with the two ways Subaru has used recently to measure air flow. The first method discussed is MAF Sensors which were used on all late models until the 2000 model year. From 2000-on Subaru has begun using a speed-density system which primarily relies on a MAP sensor. MAF Sensors Mass Air Flow (MAF) Sensor is used by the engine control unit (ECU) to determine the weight of the air going into the engine. To do this, Subaru uses a cylinder shaped sensor mounted securely to the stock air cleaner box behind the passenger side headlight assem
