Today, very few drivers are indifferent to the dynamics of their car. These are mainly people of the older generation who use the car only as a means of transportation. Most owners continue to improve and upgrade their even new and high-speed machines. Meanwhile, this technical characteristic is spelled out in the data sheet as one of the main indicators of power. Acceleration dynamics is the time it takes for a car to reach 100 km / h.
Budget city slugs, for which the mark on the speedometer at 120 km / h is the limit of the possibility, remain out of the game, but for those car owners who understand the pleasure of a quick start and comfortable high-speed driving, the question of how to improve the dynamics of their car remains relevant. There are several options for how to get the car off to a faster start, and the engine tuning that newbies like to do is not in the first place.
Machine weight
It is possible to minimize the loss of engine power in order to positively affect the acceleration dynamics without upgrading the power unit. The first thing it is recommended to do is to throw out of the car all the "unnecessary" things that make the driver feel at home behind the wheel, but affect the dynamics of the car. If the total weight of the vehicle is lightened by only 10%, the acceleration time to the cherished 100 km / h will also decrease by the same amount:
- The spare wheel and tool kit will take approximately 40 kg of the total weight of the machine.
- Changing shoes for light wheels - up to 20 kg.
- Replacement of metal or aluminum hood, trunk, fenders with alternative carbon parts - up to 40 kg.
- Media system - up to 25 kg.
- Refueling the gas tank by 25%.
- Dismantling the rear row seats or replacing them with lighter options.
After reducing the weight of the car by 120-150 kg, you can safely minus 1-1.5 seconds from the acceleration time.
It is not recommended to remove the noise insulation from the car (however, as well as neglect the spare wheel and tools) and change it to another one made of lighter material. The same applies to changing the skin. The joy that the driver will experience, having received extra fractions of seconds during acceleration, will quickly replace the irritation from an uncomfortable trip without music and in the increasing noise.
Re-equipment of the differential
The dynamics of the car will be determined not only by the high-speed start, but also by the optimal acceleration while driving. Tuning the differential, when a short gearbox is installed, will help the driver to show the fastest acceleration, but on the track it can bring some inconvenience.
Before re-equipping the unit, it is worthwhile to carry out accurate calculations and clearly understand what you want to get from the car - a quick start in seconds or a comfortable ride around the city and the highway. It is recommended to consider the following points:
- A short differential increases torque to the wheels, but does not add power to the engine.
- If the differential has a low gear ratio, the higher the maximum speed on the track will be - the higher the gear ratio of the unit, the faster the start.
- If the car is equipped with a powerful engine initially, converting to a short gearbox will make the first speed almost useless. When starting, the engine does not realize the potential of the first speed.
- A short differential is always a short gear, shifting from one speed to another takes time.
Differential tuning is relatively inexpensive and effective if the driver calculates the gear ratio correctly. If the knot is self-locking, it helps to accelerate quickly on bad roads and accelerate well.
Changing wheels
Changing wheels to lighter ones is not just throwing all unnecessary things out of the trunk or laying out a spare wheel that can be put back in a minute. Installing the car on lighter wheels is not done for one day, but it really helps to reduce the weight of the car by 20-30 kg, without changing the grip of the wheels.
Moreover, lightweight discs and wheels show less inertia, the car accelerates easier and brakes faster. When installing lightweight wheels, it is recommended to consider the following points:
- Choose high tires on small rims.
- Tire weight should be kept to a minimum.
Increase in motor power
The re-equipment of the power unit helps to improve the dynamics of acceleration. This includes not only engine tuning, but also muffler replacement, turbine installation and much more.
Chip tuning
In fact, all devices for increasing engine power only release the potential laid down by the manufacturer in the power unit. For example, engine chip tuning. Today there are two options for increasing power:
- ECU flashing with the installation of a new program;
- installation of the module directly on the power unit.
German accessory makers (eg RaceChip) promise up to 30% more engine power. In this case, the installation of the module can be done independently. Manufacturers offer an affordable wiring diagram that is easy to figure out even for an inexperienced driver. But it is better to reinstall the electronic program under the supervision of a specialist.
The principle of operation of both the module and the chip is similar. The equipment measures in real time the parameters of the motor operation - the frequency and amount of injection, and transmits information to the on-board computer two to three times faster and more often than standard sensors. Correction of the parameters of the fuel system is accelerated, the frequency of injection into the cylinders is increased. Accordingly, the engine power is increased.
Each driver will determine the pros and cons of chip tuning independently. It is important to remember that if the car is under warranty service, interference with the car's electronic system will void this warranty, and operating the motor at the limit of its technical capabilities leads to rapid wear and tear.
Reagent 3000
Another interesting offer for those wishing to increase the dynamics of their car came from the Novosibirsk company Ruslana. The reagent for all types of engines with a volume of up to 2.5 liters is compatible with all oils and promises an increase in engine power by 30-46% for a mileage of 50,000 km.
Of course, an increase in the power and service life of the engine, a decrease in the friction of internal parts (and in the entire machine!), An improvement in the operation of the turbine, a decrease in fuel consumption, etc. only due to the wonderful fluid - this is the best offer for everyone who wants to increase the acceleration dynamics ...
Muffler
In a car, without exception, all the details are the main ones, but the muffler, as part of the engine system, is often left without proper attention. And the point is not only that the muffler is considered by many drivers to be an unnecessary element, which is designed only to reduce noise and take engine power, but also because not everyone knows its real purpose.
If you remove this element completely, the engine power will "take off" by 30-40%, but it will be almost impossible to drive a car and it will be quite dangerous. In the labyrinth of the muffler, the final combustion of the fuel takes place.
What can be done to increase vehicle dynamics by 25%? Retrofit muffler. Install a tuning option instead of the standard unit, which will both reduce the noise to the established standards, and will not allow the flames to fly out from under the hood.
Installation of a rigid suspension
It is no secret that if a soft suspension is installed in the car, then at the start from 30% of the engine energy is transferred not to the wheels, but to the springs and suspension springs. The car "crouches" and rushes forward from a low start. By re-equipping the suspension, installing stiff springs and reinforcing the springs, it is possible to ensure that the engine's energy will be used for its intended purpose.
You can add some more tips on how to increase the dynamics of the car. These are small details that, individually, will not bring a visible change in the acceleration time, but working in combination, they are able to please all speed lovers:
- Strengthening the body to reduce vibration. Here it is important not to overdo it, adding stiffeners to the body in order to get rid of vibrations and increase the acceleration dynamics by 0.01-0.5 seconds - you can also reduce it if you do not calculate the weight.
- The tire pressure must be at the maximum allowable.
- Turbine installation. This is the most effective way to increase the acceleration dynamics, but only for those cars where there is no standard turbocharging system.
If you approach the issue comprehensively, you can reduce the acceleration time of the car by 20-25% and lead the neighbors in the lane into silent surprise.
