Compression ratio

The compression ratio of a piston bottom dead center and the top dead center of the cylinder volume ratio. Change the compression ratio can improve the efficiency of the engine, but in the production process must require rigorous, because it will directly affect the compression ratio and combustion efficiency of gasoline and setting the ignition timing are closely related. In many high-performance engines have a very high compression ratio, especially in racing engines, Turbocharger For Sale but the general economic orientation of the engine but it will moderately reduce the compression ratio. With the compression ratio to improve the quality of petrol and octane requirement is more and more high, which is much higher compression ratio engine problems encountered, gasoline engine compression ratio should be more than 8.5: 1, but when the compression ratio more than 12.5: 1 to enhance the performance benefits becomes very small, and the concomitant lack of steam valve and piston relative distance, knock, pre-ignition and other attendant sequelae make the problem becomes very complex. Therefore, you must know before making to improve the compression ratio and valve lift and cam valve opening set, the correct size of inlet and exhaust doors doors even shape and size of the combustion chamber.

In addition, if the cylinder head has been milled or use a thin cylinder gasket, its associated data should also be considered. Internal components when the engine modifications, Aftermarket Auto Parts must pay special attention to the selection of materials, production requirements of precision and balance, but can not ignore the match between the components, we can see from the above engine modifications are often indeed affect the whole body, of a single Most often destroy the engine retrofit balance, and ineffective, so if you are considering modification of engine, be sure to choose a professional tuner-produced products, and with respect for professional, do not indigenous refining steel, otherwise it runs the risk of harm than good. Besides manual installation is also a major problem.

In addition to the excitation driving passion

       In addition to the excitation driving passion, one of the "flip" is also modified demands, many people want to change their car like ultra-high performance car, even if the car is not particularly strong momentum. In general, the size of the turbo engine issue "bared, bared" sound is associated with the supercharged strength - large turbocharger easier to issue such a voice. So if this sounds relatively large, this car can seem larger turbocharger, Connecting Rod people have a shining feeling.

       Many fans also modified for this purpose, his own civilian vehicle engine (such as Bora 1.8T, Passat 1.8T) internal pressure relief vent leaked into a style, and to further increase the "bared" sound, the truth and the gun drum exhaust pipe is very similar. So why turbo engine will emit sound like it?

       When we depress the accelerator pedal acceleration, throttle opening, engine exhaust temperature and high pressure exhaust energy driven rotation of the turbine exhaust gas, when the speed reaches the turbocharger work (that is, the turbine rotating at 100 000 rpm per minute) turbochargers before the compressed air around the engine intake air to increase, improve engine power.

       When we received the oil decreases rapidly until the throttle opening is closed idle state, that does not require the intake of the engine, or the air intake pipe is blocked at the throttle. But at this moment the turbocharger does not stop working! Due to inertia, the turbocharger speed remains at 100,000 revolutions per minute or more continues spinning. Now imagine,Tuning Parts at this time is compressed air continues pouring into the intake manifold, and if this can not be part of the high-pressure air in the intake pipe to drain away in time, it will make the intake manifold pressure increased rapidly, may cause Festival valve damage or intake pipe burst.

Enhance the performance of the braking system for

       One of the purposes of automotive performance improvement initiative is to enhance the safety of the vehicle, and therefore enhance vehicle braking systems is particularly important. Methods to enhance the car's braking effect are the following:

       1, using better materials, better performance brake fluid, brake pads, brake steel hose. Determine the performance of the material, so the better performance of the replacement brake parts, Connecting Rods improve the braking effect is very obvious.

       2, the installation of brake assist, a further increase braking force.

       3, replace the entire brake system. This is one of the most complete, the most effective approach. Such as the use of the multi-piston brake calipers and rotors can increase the release of brake calipers force ordinary times, so that the braking distance is reduced by 30 percent-more. Either way, only one purpose is to let the vehicle brakes more sensitive, more powerful, driving safer.
Enhance vehicle handling performance for the

       For performance car handling aspects, mainly to strengthen the stability of the vehicle, tire friction with the ground (ie tire grip) and high-speed cornering the tires when the vehicle tracking sex. In the premise of ensuring safety, increasing driving pleasure.

       Enhance vehicle handling performance requirements vary according to the owner, common are:

       1, without changing the original vehicle tires to increase the rim diameter as the diameter of the case to upgrade, the error can not exceed 2 percent sign. For example: the original car for 185/65 R14 tires can be upgraded to 195/55 R15 or 205/45 R16.

       2, for the pursuit of high performance sports car owners, you can put the original car softer and not adjustable anti-vibration devices, and replaced height adjustable soft and hard the road version of the anti-vibration device. When reducing the speed of the tire and the ground bounce and body tilt steering.

       3, often run high-speed vehicles, can be reinforced chassis, install some spars, but not to the chassis weld reinforcement.

       Section generally contains more than three major projects to enhance the performance of the car, as long as these three parts around rationalize upgrade, you can take the initiative in improving vehicle safety while enjoying fun to drive performance improvements brought by avoiding everything that can happen the accident!

       Above economical retrofit projects, spend much money, the effect is significant. As mushroom head, as long as banana, racing ring jets, super-cylinder line, brake booster, crossed ventilation brakes, additional fuel filter, water burner, etc. Turbo Accelerator is a favorite of fans, but the cost is very large, most well according to individual needs, as appropriate modifications. Power windows,Aftermarket Auto Parts power antenna, sunroof, car radio, etc. These are not listed and driving independent account.

Getting Started series of modified car fuel system modification

In fact, when the fuel system modification can not change the basis of the project, but also to understand the principles of future upgrades helpful!

       Supply system

       Fuel system including the composition of the oil pump, into the return line, fuel rail, fuel injectors, back to the oil pressure valve. The principle is to produce a hydraulic pump, a pressure valve controlled by hydraulic oil return the size of the fuel injection nozzle is turned by the ECU in a reasonable time. Why do you want to transform the oil supply system? Because the air-fuel vehicles within a reasonable range, if the intake air is increased without increasing the fuel supply will lead to a mixture too lean (hard acceleration at full throttle when the most obvious), is not conducive to mixed gas deflagration, severe cases may cause detonation phenomena. Primary modification is the replacement of the fuel system back to the oil pressure valve, an appropriate increase oil fuel system, Connecting Rods which serve the purpose of increasing the fuel injection quantity per unit time. Formal conversion back to the oil pressure valve is used can completely replace the original. The correct installation method is to take down the original pressure regulator. The famous brand SARD, TRUST, FSE and so on. This modified parts can 0.1BAR trimming fuel units. If the engine has not been significantly modified, the general should not adjust the pressure is too high, Aftermarket Auto Parts otherwise it will lead mixture is too thick, but the effect is the opposite. Appropriate adjustments must not lead to increased pressure on a lot of fuel, basically can be controlled within 1L / 100KM relatively poor quality. But be careful not to buy when purchasing some bad quality brand-name stuff, poor quality of these properties back to the oil pressure valve is in use for a short time, the fuel pressure value is automatically reduced, even down to the set than the original even lower. This is because the product material problems, leading to early decay, although cheap, but with a short cycle, if you do not want to repeat the investments, should choose a good brand, quality and quality can only be guaranteed. And a good brand of fine-tuning is also very accurate, to ensure a good modification effect.

Multi-engine jets injection system

Increase engine power is the major automobile manufacturers compete link, multi-throat injection (Multi Throttle Body, or called independent throttle system) technology has been become an effective way to improve engine performance, many specializing in high-performance engine known manufacturers have had to use this technology, but unfortunately the original configuration of this design are mostly racing engines and high-end sports cars, additional modifications are only a handful of heavily modified cars can see rare and with a little mystery. This article will take you to learn more about multi-engine jets injection system.
For multi-quantity production of civilian cars,Shock Absorbers the engine in the design and manufacturing process needs to take into account the difficulty of making and production costs, the largest component simplify its appeal. On the other hand, consider the practicality of the design of power output and fuel economy is also very important, not only with a single throttle can minimize production costs and the difficulty, and the fuel economy and practicality to get a better balance . Available for racing or high performance models, higher intake efficiency to ensure maximum power output, in order to pursue high peak horsepower and acceleration forces moment and posterior segment,Auto Performance Parts in this principle, the production costs and fuel economy will later on the dynamic performance of the consideration, which directly injection system using multi-jets. The use of this technology, almost naturally aspirated engine has reached more than 100 horsepower performance or power.

Converted the penalty area and converted direction

Modified car racing from almost all the way and modification parts are modified in motorsport through continuous testing and improvement, Adjustable Coilovers after the trial to the public to promote. Modified car development today, the owner of the car has not only seek to pull the wind in appearance, safety, practicality must also be considered, especially in the family car owners. Last week, the reporter made a special trip to a number of professional car modification shop check it out, and see what the market conversion trend.
N O .1 installation of the tail

Commonly referred to as "tail" called for more professional spoiler, more common in sports cars and sports cars. Tuning Parts Now there are some common car fitted with "tail" spoiler.

Experts dotting: The role is to increase the stability of the tail, which is more crucial for big cars, but the power is relatively small displacement cars will be affected. Rear wing spoiler parts belong to, have at high speeds to improve downforce and body homeostasis of features, but if adjustment is not good, would be counterproductive. Generally more than 100 kilometers per hour at the time, the tail effect was more obvious.

Turbocharger into the car enthusiast's vision is decades later things

As used in the automotive sector, mechanical supercharger to get more free Ying favored product is relatively mature much earlier. 1920s and 1930s, Adjustable Coilovers when the high price of the turbocharger still only be used in the field of aviation, mechanical supercharger has already swept the major European and American track. That's two most famous cars were from AUTO UNION (Audi's predecessor) and Mercedes-Benz. AUTO UNION installed in the car with a value of 1.8 bar of boost levels supercharged 6.0 liters engine compression ratio 9.2: 1, and methanol as a fuel, in 5000 r / min output 520 horsepower another department also uses two mechanical supercharger Benz M125 is able to release a 646 horsepower.

Turbocharger into the car enthusiast's vision is decades later things. Into the 1950s, GRAND PRIX Grand Prix rules were modified to make Ferrari naturally aspirated engine is gradually emerging dominance in the European arena, a mechanical supercharger begin to retire from the game, and has since poured into a high-performance modified car market.Tuning Parts In the absence of power limitations, many companies have produced a more powerful supercharger, and the only constraints on the price of such a device may be a.

1960s mechanical supercharger should belong to the United States the greatest contribution. With a large number of post-emergence and can be mounted directly to the convenience of the engine, the pursuit of high-powered fans miniaturized mechanical supercharger V8 engine to be modified often will be the placement of a mechanical supercharger exaggerated. This is probably the most representative period McCulloch and other enterprises of Frenzel. After the 1970s, in order to work with Chevrolet V8 engine compete in the NASCAR race, specially designed Ford please McCulloch supercharger, and 400 meters straight racing also contributed to the supercharged engine swept the US market.
