We all take joy when the car find ourselves in a hole and give us coffee or our teeth chattering mouth. If I do until everything is opposite! However, there are some who equip their car with sports suspension. Why we make the car more rigid and lowered?
The first option of every addict. Why sport springs? There are several reasons.
The first and most obvious, including video, is Lowered to your car. A lowered ride height automatically mean a harder spring, because the car is not lowered suspension is accepting the same race. It should be decreased by the closing. On the opening, it must be preserved, maintaining the race silencer series.
Mounting sport springs provide improved roadholding default. It has two sources: lower center of gravity of car body tilt on cornering and shrink (body-roll), and start braking.
Sport shocks enter the scene in those who do not want a car just look down, but a ride to match its looks.
Why we need sports shocks?
A series damper has a certain race. Suppose we acquire a spring sport down by 40 mm. From the beginning of the series damper down the final point of operation by 40 mm. Acceptable, given that race still has loading situations, bumps, special dynamic conditions. Same arc, must quickly compensate and race silencer without opening it emerges, giving rise to sound annoying, but the possibility of salt in position.
This means that the arc must have been enough to offset lungimer damper opening. So is a compromise. However, there are cases when the damper of the series, with one race too long, reaches end (bottom out) and can destroy.
Sport silencer allows us to give up this compromise. Race may be shortened and automatic damper spring may be shorter. A short arc means less resonance introduced in this compression / relaxation repeated fast. A mass damper is not always face a tougher spring. Sport dampers are usually tougher and have longer life than a series damper if they are supplemented by a spring sport.
Adjustable suspensions are best suited to a leading sports / sports application (racing). By changing the spring and damper and strengthen both the level of performance is achieved over that of a sports spring kit sports silencer. Arch is much smaller in diameter than a sports silencer series, does not induce almost no resonance, so only the damper filtering normal suspension travel. Usually damper rod is much thicker in diameter, making the front shocks with brio in a very aggressive driving. Most come with adjustable suspension dampers adjustable in hardness.
If you purchased such a suspension would be good to check with a person able to show you the recommended hardness level. It is very possible to screw the car ride damper making too hard or too soft.
May all adjustable suspension adjusts ride height of arch support (its pan), which makes suspension a bit hard to adjust, because once it move and compress spring / decompress (adjustable suspension cases only one arc).
There are suspensions in which the adjustment is moving the entire damper spring up and down, pan from being on pretensions arc (hardening) spring. In this way paote choose a softer spring suspension, which may strengthen the need ground clearance of the car can remain the same.
These suspensions are mainly used in racing cars, the springs are usually very hard and with limited suspension travel from 10 to 12 cm. Adjusting damper has a very wide beach.
In these suspensions adjustable compensating can add (those external tanks) to adjust both their opening and closing (bound / rebound). In this case, the damper is adjusted to its closure of compensating open air.
Let's see how little theory synthesizes the damper and springs:
- A hard spring to shake;
- A strong spring will greatly reduce body-roll;
- A strong spring will shrink during the rebound damper;
- A soft spring will not blow the car bumps;
- A soft spring increase braking distances;
- A telescope must be harder than the climb descent;
- A telescope hard on lowering the car to have trouble determining grip (traction / direction) on a bumpy road;
- A heavily lowered car will require a readjustment of the wheel angles.
And all without to take into account the hundreds of possibilities for adjustment (set up) the suspension vehicle depending on need, application, driving style and many other variables. That their usefulness is proven and approved, this is clear. But any change to the suspension at least Erste well to consult a professional to make a recommendation for your own needs. What works on one machine does not necessarily give the same result and the next. With a little care and a moderate investment can dramatically improve the way the car is in drive and rectioneaza situations.
Auto Repair – Basic Tools
Safety first! Every car owner should have his own safety and those around him his top priority. Contrary to common belief, cars are as dangerous on the road as they are when being repaired. When repairing the car, basic safety rules and specific limitations of tools and workplace should be considered no matter what type of auto repair you do. The following are some common auto repairs: engine oil and filter change, spark plug replacement, brake pad replacement, timing belt replacement, rotor replacement, air filter replacement, drive belt replacement, water pump replacement, head gasket replacement and check engine light.
If you want to do your own repair or maintenance, you need to have a good repair manual or proper automotive repair book. An auto repair manual will help you do your repairs quickly and reliably. Aside from a manual, it is also necessary to have a set of tools for auto repair.
One tool is set a combination wrench set. It is a good set and belongs to a specialty tool collection. Because most of the repairing jobs will require a tool to either twist bolts and nuts to a certain way or fit into a small space, a stubby wrench set is needed for those tight spots. This is not really a must have tool because you won’t be using them everyday but it is a good addition to your tool set.
A hex wrench set is another important tool every auto repair technician should have because hex bolt is commonly found in automobiles. This tool set is used on almost everything from the starter to the gear shift knob which allows a lot of strength when twisting tough bolts.
In addition to wrench set is the ratchet wrench and socket. The ratchet is considered as the backbone of any mechanic tool.
A breaker bar is another one. If you want to loose a very tight nut or bolt, though you can slide a pipe over the end of your wrench, the breaker bar will do the job much better. The breaker bar has a flex handle that adds a lot of twist for you to pull on the nut. A breaker bar is a must have for your auto repair box tool.
A screwdriver set with good sizes and types should also be in that repair box tool. A screwdriver is a tool for tightening screws.
Likewise, fluorescent shop light which serves as a work light in seeing the recesses of the engine bay or underneath the car, is a very bright, cool, durable and don’t get hot sort of lamp. It’s a 25-foot cord with a built-in plug and doubles as an extension cord.
Furthermore, if you need to creep, it is easier to roll underneath a car in a super durable and easy-to-use bone-ster car creeper. You should be lying comfortably on it.
As with anything else, you cannot do a job perfectly without the proper tools. However, if you can’t handle the repair and time doesn’t permit you to do it yourself, let the auto repair shop do the job. You just have to find a good mechanic who is pocket-friendly and trustworthy for your vehicle.

Turbocharger
Turbocharging is a term used generally for any kind forced air induction through mechanical supercharger or with a turbine. The gas turbine is the most effective way to increase the internal combustion engine's power, known as a Turbocharger. Internal combustion engines are known to be very inefficient, using only one third of the energy resulting from combustion in order to rotate the crankshaft. The remaining two thirds are used for cooling, losing on the third for the exhaust system. For example, a naturally aspirated 200 hp engine throw the equivalent of 70 hp power as heat, directly on the exhaust pipe. However, a turbocharger uses exhaust gases, so most of the heat and exhaust gases are used to force more air into the engine.
The position of the turbocharger on the exhaust gallery restricts in some measure gas output from the engine, but power losses are much smaller than with a mechanical compressor. With a turbocharger the lost power is around 5-10 hp for each 100 hp the engine has. The size of a turbocharger is much smaller than that of mechanical compressor, so, bigger turbos can be added which increases the amount of air forced into the engine and the gain of the horse power is also substantially increased according to it's size.
The turbo compressors has 3 key parts: the gas turbine, bearings and air compressor. Gas turbine blades and air compressor blades are connected by a shaft mounted on bearings. Some turbines can support up to 2400 hp and have the option of ceramic ball bearings. There are several types of turbines, depending on specifications air compressor.
A: gas turbine blades
B: bearing and seal
D: shell gas turbine
E: plate separators
F: air compressor blades
G: air compressor casing
H: shell bearing
I: inlet mouth
J: outlet
2010 Volkswagen Polo GTI
The new Volkswagen Polo GTI has been unveiled, promising to be the fastest, most focused and cleanest performance Polo yet produced. The original performance variant of the Polo was unveiled in 1986 in the form of the G40 Coupé – a car that mixed a fast-revving, 113 Hp, supercharged engine with a low kerbweight and sharpened responses.
Fast forward 24 years and the new Polo GTI bears similarities with the G40. At its heart is a 1.4-liter TSI engine that uses a supercharger from idle through to 3,000 rpm at which point the turbocharger cuts in to provide boost. The result is an output of 180 Hp at 6,200 rpm and 184 lbs ft of torque from 2,000 rpm which, when aligned with a 1,184 kg kerbweight, allows the Polo GTI to accelerate from 0 to 62 mph in 6.9 seconds before reaching a top speed of 142 mph.
Despite a keen focus on performance, the new Polo GTI is capable of delivering 47 mpg on the combined cycle while emitting just 139 g/km of CO2.
The TSI engine is linked to a compact seven-speed, twin-clutch DSG gearbox that channels drive through the front axle. In addition, the Polo GTI is fitted with the XDS differential, an electronic cross-axle traction control system for improved traction and handling. The XDS system is a functional extension of the electronic limited slip differential (LSD) which is a part of the standard ESP system.
In order to sharpen responses, the Polo GTI is fitted with new springs and dampers which results in a 15 mm lower ride height than the conventional Polo.
Like its Golf GTI sibling, the Polo GTI features significant aesthetic changes. A new front bumper featuring a deep airdam is joined by a honeycombe grille element with horizontal red strips and a simple GTI badge. New headlight units complete with the option of LED running lights lend the Polo GTI an imposing new look.
Further back, a subtle sill extension wraps around the lower edge of the body while at the back a new rear bumper features a small diffuser and a pair of chrome-tipped exhausts. The Polo badge is replaced by a simple ‘GTI’ version.
Finally, a set of 17-inch wheels identical to those fitted to the Golf GTI are fitted along with a set of red brake callipers.
The changes continue inside the Polo GTI with revised dials, a new, flat-bottomed GTI steering wheel complete with small gearshift paddles and contrasting red stitching, aluminium pedals and new, heavily bolstered front sports seats finished in tartan trim. Subtle gloss black trim covers the centre console while the headlining is now finished in black.
The new Polo GTI is due to go on sale in Europe in the summer at which point pricing and specification will be announced.

Russ Varney, Chief Programme Engineer, XK Series, explains the philosophy behind the uprated XKR:
"With 510PS and 625Nm of torque, the XKR has immense reserves of power and acceleration which impress everyone who experience it. The car has always had the potential to reach speeds far beyond its original electronically limited maximum and many of our customers have expressed an interest in a car that can safely be driven faster where conditions permit. The new Speed Pack allows them to release some of that potential and give them control of the fastest Jaguar XK we’ve made to date.”
