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

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

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
