A View on Customization

Every company who designs car from Sports cars to State Cars they always designed to withstand upto 50% of its own limit that my friends is called a Cars Capability !

When talking about an engine , its capabilities r also more then that at which it was put in to the engine bay from the company !

that is why , when it comes to customizing your ride u can boost up to  " 1000 HP " Specially Engines which were designed to be modified in the first place like the Lance EVO Engines , These Engine take the Cake when it comes to modification Because these Engines are Strong , Even in my country there is a Lance EVO VIII Which has 780-900 HP ,

And Let me Tell u Its " HELL OF A FAST CAR"

But with this much power and Speed comes great loss as well like this guy has to change the oil after every 3-5 runs and that is not even 100 KM , plus he Brakes his Clutch more offen then any car i have see ! But nonetheless he keeps going ! 

well That is what i have

and i know it has been a Year or so Since my last Update ! But Shit Happened so i couldn't do anything and 2013 was the Worst year of my Life so Hopefully ill keep Updating this time around 

Engine Differences

Some people i move around about , dont know the difference between the engines of the same make and model

when i was with a friend of mine he didn't know that a car company provides different engines for the same model of the car and i was a bit surprised by that because i though people knew at least this but i found out that most of the people don't know this ! 

so i though i explain a bit !

lets take the example of toyota company in our country !

Here they provide 3 different engines for the new Toyota Corolla

1. 1.3 liter with a Manuel Transmission
2. 1.6 liter with a Manuel and  Automatic Transmission
3. 1.8 liter with a Automatic Transmission with Cruise Control

so what the difference between these engines well the first one is the smallest engine of the three because it can only take 1.3 liters of air and fuel mixture in total !how come because its cylinder size is smaller then the other two ! in the second Engine the intake size is increased , the block and the head r all the same even the crank shaft is same only the diameter of the cylinder is bigger and the piston r a bit wider then the first one !

now for the biggest engine , As always it has the same things in it the same sensors the same block and the same head expect this has the biggest diameter and pistons of all the engines thus it has increased power then the other two !  The only Big  difference is that it has some thing Called a Cruise control which only replaces the throttle body with a one that is cableless because in cruise control the throttle is opened by a stepper motor instead of a accelerator cable !

hope this was helpful to some people !
And if i am wrong correct me !

Painting

The Painting of automobiles is an art as well it is same as painting your house but with a lot of extra working

The main thing in doing a repaint of a car is "sanding" u have to do sanding before everything you do when painting a car i.e

1: Before starting to paint u have to sand it too get the previous paints gloss out completely so the surface can become prepaered for the new paint (if repainting on the previous paint)

2: After the gloss is done u apply the premier and u have to sand it again to get a smooth enough surface that the paint will stick to the premier and not rough enough as well so that the paint doesn't produce deflects due to low adhesive surface . usually its done with a p800 sanding paper with or without a sander

3: After the premier its the surfacer sanding job if it is required but now a days the premier comes with the surfacer so it requires only the premier sanding

4: Then come the last sanding of the paint which is done using the p1200 or p2000 sand paper to smooth the paint surface that gives it the smooth and shiny gloss look

5: If u want even more detail and smoothness then u sand it even more with the highest no of sand papers like p4000  ( this is the last of the no sand papers on the car ) but it is not necessary that u do this

Hope this was helpful
And if i am wrong plz feel free to correct me !

Turbo Tune-up

OK !!

In my country motor sports is a very small peck on the charts so that is why lame tuners tune cars in ways that they lose 50 % of there power because they done know how to tune a turbo , they know how to install it , tho it doesn't get them any where plus it wastes there effort as well , so Todays topic will be about Turbo Tuning 

How to Tune a Turbo :

ill talk about in detail how to install a turbo later on , but for now ill just tell how to tune a aftermarket turbo or a custom turbo !

First of all the people think that turbo has to misfire all the time at high RPMs , " Nooooo " the turbo only misfires if the pressure in the cylinder exceeds then what the cylinder can withstand if u give more then the cylinder can handle it will only make u lose the power u want to generate instead it will make to even more slower then other cars at high RPMs that means your torque and speed will start to fall as soon as the first misfire happens

And i am not talking about the GT lvl Turbo's they have something called a misfiring system which works in a different way then a regular turbo misfire

Now to tune a Turbo u must know how much your engine can withstand the turbo boost like 1-2 bars or more most turbos give a boost pressure of 1.5 bars and that alot to gain 25-50 bhps in a engine the main thing to set is the blow off or a waste gate at appropriate tension so that when the turbo start to misfire it can control the intake pressure and control the misfires

and the turbo should match the engine specs as well , if u put a big turbo and get it to work some how it will only cause high temperature rise in both oil and coolants and can cause a engine blow

The turbo u choose should be good enough that it can give your car a efficient boost and not waste the power at any RPMs or condition

and the a turbo should be placed where it can get air to cool it down (if air cooled type) and u should always install a water and oil temreature gauge when u install a Turbo

If u find any mistakes or i am saying it wrong then comment me !
 I am still studying so i could be wrong so correct me if u can !

Auto Paint

since i am trying to be the ultimate technician in the automotive field i took a test conducted by the toyota T-TEP in which i choose the field of auto painting !

i have done the classic paint job at the moment but during the next class they will teach us how to mix different paint according to the dealers or customers requirements and then come the custom paint jobs which am waiting for

So in time ill be a master painter as well as a master moder and the ultimate technician. ill try to post about paint technologies as well

ABS ( Anti-lock Braking System )

ABS is a device which is used to assist braking (that means it only help in braking) its consists of solenoid valves , a few extra brake lines and sensors and its own brain (ECU) which is connected to the main ECU as well to receive some info from the EFI sensors and normal sensors ( like vehicle speed sensor )

Purpose :-
The main purpose of the ABS was to stop the locking of the tyres due to hard pressing the brake pedal in a emergency because locking up the tyres causes loss of traction in mid and high speeds when the car has momentum in it , this prevented the car to slid of when the brake pedal was pressed hard and provided good stability of the car but it eventually evolved and now a days the ABS system controls almost all the function of your braking even braking for u if your too busy flooring the gas pedal in a corner or in the streets

Now the ABS is paired with something called Traction control and VSC (Vehicle Stability Control) which control all the situations occurring in one's car which could cause loss of traction on the road or track (Tho some people tend to turn it off during a run on the track)

Working :-
The ABS works with the 4 ( 1 for each wheel ) or 8 ( 2 for each wheel ) solenoids given in the ABS unit which work by transferring the brake fluid from one line and give it to the next line thus assisting the braking to brake all for wheels at the same speed no matter what the condition( as if the vehicle is on the a watery surface) so the vehicles doesn't lose traction while braking . It got popular because it provided safety and also because it provided improved track timing for the new generation of racers

The Traction control and VSC work by using three more solenoids one to cut out the master cylinder during a hill climb turn and hard pressed turns when you can not let go of the accelerator . Then it uses the second and third solenoid to give stored pressurized brake fluid and give it to the ABS to work its magic with it like you r press the brakes at a professional level. It works at times like when one of your cars wheels is stuck in a ditch and the power is going to waste at the wheel which is above contact to create pushing force , at this time the Traction control lock the slipping wheel and the power moves to the wheel which has a contact with the ground thus your car runs out of the ditch . The VSC work on the roads or track where u cant press the brake because u will lose the power from the engine if u do that it automatically brakes and release the wheels to provide the best traction of the wheels with the ground so your car moves smoothly through the turn

Problems :-
The common problem with the ABS system is the relays which power up the ABS system and blown out fuses , on rare occasions the solenoids become weak or stop working or the rubber seal on them becomes weak , and on even more rare occasions the ECU gets fried but it has alot of fuses and breakers protecting it so it rarely happens

The ABS has a fail safe Function in it that means if there is something wrong with the System it will return to its original braking method

Braking Systems

Today we talk about how many types of braking system are there . Mainly there are four Types of braking system used in vehicles and they are :

1. Mechanical Brakes
2. Hydraulic Brakes
3. Booster Brakes
4. Air Brakes

Mechanical Brakes : Mechanical Brakes use lever , rods and wires to work , as in when u press the lever it pushes the wire which causes the braking pad to stick to the drum creating friction to stop the car , it is a simple braking system which consists of levers and wires , it is mostly used in bicycles and low powered motorbikes now a days

this is just a bicycle brake 

Hydraulics Brakes : Hydraulic brakes consists of cylinders , pipelines and proportional valves . This type of  braking system uses fluid , which when becomes pressurized creates extra force then what is applied to it . when u press the pedal the fluid inside the master cylinder is compressed so it travels to the moveable point creating extra force but when reached it is blocked by the pad which starts to push the pad or shoes towards the disc or drums and applying brakes this type of system is used in almost all the passenger cars

A simple working of hydraulic brake system

Booster Brakes : Although its is similar to the hydraulic braking system , this is system consists of another part which is called a booster which increases the applied force by using the engine vacuum created in the intake manifold . It consists of a diaphragm which is static until the pedal is pushed which cause the diaphragm to move in the direction of the master cylinder pushing the piston with it and creating a multiple force on the piston to push the brake fluid to the brake cylinders this pushing the pad against the disc with increased force

This is a vacuum booster

There is an air power booster as well which instead of vacuum uses compressed air to work and multiply the force , but cars mostly use the vacuum type since it as lesser parts then the air powered one thus cheaper to manufacture and powerful enough to stop the car

Air Brakes : This is a totally different type of  braking system which consist of

1. Compressor
2. Air Compression tank
3. Relief Valves
4. Air Lines 
5. Pedal Valve 
6. Air Wheel cylinders
7. Air Release valve 

With all these thing in one braking system its hard to image where it would all fit especially a tank of compressed air and its compressor, well this type of braking system does not come in passenger cars or sports cars , It is a system designed for medium and heavy duty truck and trailers . Because even though trucks and trailers don't have high speeds the load it carries causes a hurl effect on the truck causing it to lose traction thus powerful brakes are required by them to stop properly with heavy load

That is a lot for a car to handle

there are air brakes in cars as well but not like this one , they are different and work at high speeds and they only consists of a motor and a hydraulic spoiler 

And Finally if people are confused that where is the ABS Braking system , well for your information ABS is not a braking system itself it is a assist system put on booster or hydraulic braking system to provide good traction in any weather and its main purpose is to stop brake locks which happens when u push the pedal too hard causing the tyres to lock on and lose traction causing accidents

Well that's it ! Hope This Was helpful

Thanks to all !
