How-To: Tune Your Car

[SCRTW34P0N]

---------------------------------- Continuing from Part One ----------------------------------

-----------------------------------
SECTION 3.4 - PARTS - INTAKE SYSTEM


Your Intake plays a major role in maximizing your engines HorsePower. That is because your Intake system is what pulls air into your engine. It is the very beginning of your AirFlow. You have to mix and match your Air Filter along with your Intake piping just like you do with the Exhaust. No air filter works the same with an Intake pipe. You want to tune according to your engine specifications. That being forced induction or naturally aspirated. In some cases you will use a fairly large intake pipe for a naturally aspirated engine. A good example of this is a Natural Scion TC which uses a 115mm Intake along with a Large high flow filter. Of coarse you will want to use a larger intake pipe when using Forced Induction, just so you can feed the engine the air it needs.

---------------------------------------
SECTION 3.5 - PARTS - FUEL SYSTEM


Your Fuel System is critical to running a safe setup. If your engine isn't getting enough fuel then you are more prone to engine damage. In order to fix this problem you will want to purchase an Air/Fuel Controller along with other Fuel parts. If you have purchased an Air/Fuel Controller you can go into the Dyno and specifically tune it to Rich or Lean. A Rich setup drastically lowers your HorsePower, but increases your durability by an insane amount. As for Lean, it is the complete opposite. By leaning out your engine you are creating a possibility of breaking your engine. It creates a higher amount of HorsePower at a cost of breaking.

There are certain parts you can purchase in order to help your Fuel flow; those being Fuel Pump, Fuel Rail, Pressure Regulator, and Injectors. Your Injectors play a major part in pushing fuel into your engine, but you need to get your fuel to the injectors first. There a many different Fuel pumps which do produce different amounts of Power/Fuel. By purchasing a Higher flow pump you will be pushing more fuel through the lines. Obviously this means you will have more fuel going to the engine creating a more Rich situation.

A Fuel Pressure Regulator helps pressurize the Fuel Lines allowing it to flow freely to to engine. Without the correct pressure your fuel wouldn't be able to get to your engine fast enough. Take a Water Facet for instance.. if the water lines to the facet aren't pressurized then it will only drip out of the end. This is not what you need for a highly modified engine.

Fuel Injectors are what spray the Fuel into the engine. The amount of fuel delivered is measured in Cubic Centimeters. The higher it is rated, the more fuel your engine will receive(ie, 400cc, 550cc, 650cc, 680cc, 800cc, 850cc, 900cc, 1000cc, 1080cc, 1200cc)

----------------------------------------
SECTION 3.6 - PARTS - ELECTRICAL/IGNITION


Electrical and Ignition doesn't play a huge role in producing power for your engine, but it does help. What you want to focus on in this subject is your Spark Plugs and Cables. In some cases you can have an increase of up to 30hp between the two. Spark plugs carry electrical energy and turn fuel into working energy. Working energy in this case is your engines Horsepower.

Another great addition is to have a A/F Meter so you can maintain a safe A/F ratio. If you can purchase a A/F Controller this will be better because you can actually controller your mixture of air and fuel.

SECTION 4 - TUNING


I put this section in to try and help everyone with successfully tune your vehicle to its maximum performance. It will include tips about Ratios, Weight, Tires, Rims, and more.

--------------------------------
SECTION 4.1 - WEIGHT REDUCTION


Reducing the weight of your vehicle with increase performance by a substantial amount. You can do this by purchasing Lighter Body Kits(ie, Carbon Fiber Hoods, Trunks, Bumpers) There are performance seats that can be purchased to replace those heavy factory seats. Even replacing the stock battery with a performance battery can increase performance. Rims do play a major part in not only your vehicles weight, but in how your vehicle literally rolls. I will go ahead and discuss the weight part of this topic. In the game, the lightest rims are the HRE or B Sport brands. The most popular of the two are the HRE 547Rs or the B Sport LM rims.


--------------------------------
SECTION 4.1 - RATIOS

Ratios play a major role in how fast your car is and so does the rim size. You want to cross the finish line in your final gear ( 4th, 5th, or 6th ) right at your cars redline or rev limit. Why your rims play a major role in this is because you can have ratios for stock 15" rims which you finish just at redline when you cross the finish. When you purchase say, 20" rims, you have a larger surface area you are rolling on. With those old ratios you will not be able to make up the extra feet you need in the amount of time to cross the finish line at redline. To make that explanation simple, when you have ratios for a small set of rims, in this case 15" rims, and you put a larger rim on your car (20"s) those smaller ratios are going to have a hard time to turn your new set of dubs a full rotation because they are larger.

If you want to maximize performance by your engines horsepower. You are going to want to dyno your car and look at what RPM(Revolutions per Minute) you have the most power at. By doing that, when you race your car you want to pay attention to where your RPMs drop after shifting gears. You want them to fall in the range of where you have max Horsepower.
