How do I make my car go faster?

If you've been looking at your car and your bored with the way it feels, perhaps its time for some mods to get it a little quicker.
Keep in mind the following 6 Top Secret items before you start:

1.

Carbon fibre air intake enclosure to suit Evo 7,8,9 from Top Secret Service Centre

Depending on the type of car you have e.g. turbo non turbo, you need to keep in mind the what you can and cant do. For both NA (naturally aspirated) engines and turbo's you need to make sure there is enough airflow. Quite simply oxygen in the atmosphere causes fire to burn. The more cold air we can supply the motor the better your chance of combustion. This is usually via an air pod or filter. Make sure that its legal and enclosed, any fine and defect clearance that is needed will simply out way the reasons not to do this from the start. The aim here is to force cold dense air into the system. A common mistake is to enclose the air filter with a box but not allowing the outside cold air in. Sucking hot air from around the motor will not give you the maximum power gains.


2.

An example of an exhaust system.

More air out, ensure that exhaust gases can leave the engine as efficiently as possible. A nice exhaust system will take care of that. Again there are legalities around the catalic convertors for emissions and noise levels which need to be addressed.
For non turbos you want a good set of tune length extractors, 4-2-1 extractors are for good low end power and 4-1 for high end power.


3.

Intercooler kit complete with front mount cooler and piping.

A lot of the Japanese cars are restricted purposely in the factory to ensure they meet emmisions standards or power standards. Piping around the turbo and intercooler is changed from rubber to metal to help regulate the pressure. Sometimes standard factory pipes can expand or 'balloon' changing the flow of air and causing lack of throttle response.Increase the flow of cold air for the turbo. This is achieved by ensuring you have a larger intercooler and piping. In many vehicles the intercooler may need to be replaced with a larger front mounted intercooler. In some cases a simple piping upgrade will suffice.


4.

A fuel pump with fittings.

Now that the vehicle is unrestricted, and air is flowing freely in and out of the motor, we also need to ensure that there is enough fuel supply going into the motor. Its all about adding enough air and fuel to the combustion mixture. If this ratio is not correct the motor will lean out and require to be rebuilt. In most cases we need to upgrade factory fuel pump, these are usually located in the fuel tank of the vehicle.


5.

HKS boost controller one of the best on the market.

Increase the boost pressure of the turbo, boost is measured in barometric units, also known as 'bar' for short. 1 bar of boost is equivalent to 14.7 psi (pressure per square inch). This will increase the displacement of the motor, in short increase the power. This does place extra stress on internals of the motor. Most good tuners do understand what a good level of boost they can increase from standard as each make of motor is different. Its recommended to have an electronic boost controller to standardise the boost increase. As factors such as the external air temperature will effect the boost levels. (cold air is more dense than hot air).


6.

Project D Drift Schools car being dyno tuned.

We have added a lot of non standard parts by this stage. To me it feels more like a random group of people trying to play in a band together. The factory computer needs to be made aware of these changes and tuned accordingly to achieve optimum results.
After a good dyno tune the power output, petrol consumption and driving response is a lot smoother and better.

In summary, do your basics first, understand what the above modifications will do to your car. By knowing this you can begin with the end in mind. What are you trying to achieve with your car? Do you want it to go a little faster? Are you planning to track? Drift? Drag? What is your budget? When you start to answer these questions you'll get a lot more enjoyment from you car and the value for money from your spend.
