OK I have a question ... ... ... ...

 

Can someone explain for me (in laymans terms) what PSi, Bar, Torque and boost acctually means/does?

 

OK I am stupid but after a conversation with someone at work I know that thinks he knows everything I am even more concerned/confussed.

 

He says that PSI and Bar are the same but its a UK and USA terminology?

 

But I said it cant be because the lads in my club use them in the same tense and not as alternatives. He says you are wrong. I wont give him a right hander for saying that but told him to fook off. :rofl:

 

So please explain if you would what it all means so I can piss him off next week at work.

 

thanks Vini.

PSI and Bar are both measures of pressure.

 

PSI meaning "Pounds Per Square Inch". Basically the old Imperial method.

Bar seems to be the preferred International version.

 

1 pound per square inch = 0.0689475729 bar

1 bar = 14.5 psi

You've also got "Atm" meaning Atmospheres, Centimetres of Water, Centimetres of Mercury, to confuse even more.

Thanks mate. I know that they are measures of presure I have seen it on a tyre presure gauge to state the obvious. I am after a description of what it all means. ie: where/why does it all happen? where does torque come into it, I know what toque is too but I just dont know how it all comes together within my TT car?

 

To make my request clearer I hear some saying that they can achieve X amount of boost and that its running X PSi and the car has got X amount of Torque ect ect.....

 

I need to understand I spose or I may remain a numb nuts for ever... :D

here you go http://www.howstuffworks.com/turbo.htm and more tech explanations here http://www.300zx.org.uk/general_tech_info.htm

Its easy??? lol.

Basicaly, an example of tourque would be............

 

Horsepower is the speed of a punch

tourque is the strength behind a punch

URGENT... Please can someone help me, please!!! I'm trying to locate/contact a guy called 'Martyn' who is has disappeared along with my beautiful ZX (TT). I haven't had any contact with him since Jan. 07. He used to run a garage in LINCOLN (in the north of England) and also in HORSHAM. Please can someone help me, just want my car back, doesn't matter if its fixed or not. Please can you contact me on 0777 349 52 61 if you have any information. Thank you.

Fundamentally he is right. PSI and BAR are the same in the same way that lb's and kg's are the same thing. They are measures of 'x'. Many people on here will post and say I'm running x PSI blah blah blah x BAR. In essence though they're just repeating the information. It's like saying this bag of sugar weighs 1kg and it's not easy to balance a 2.2lb bag of sugar on your nose.

 

If that's not the best analogy you've read today I'll eat my donkeys hat.

 

As you increase the boost pressure you're compressing more air into the cylinders. More air = bigger bang = more horse power.

 

There's a very simple formula:

 

f=fuel

cda=cold dense air

s=spark

 

 

f+cda+s=lol

 

Hope that helped.

1+3+3=7

1+3+3=7

 

Not on my watch Mr.!

Thanks Jonno and everyone else. So if I were to get a boost controler then turn up the boost I will be creating more PSI/Bar? That makes sense. I know it sounded stupid and I know what PSI is its just that I have seen both used at the same time therefore thought they were being used for 2 different things.

Standard boost now...Is it 7 and on some 14? And what is the 7/14, PSi/Bar?

vini

1 bar = 14psi

 

if you were boosting 14 bar, youd be driving a nuke!

 

if your thinking of the boost gauge on jap models, they use metric... kg/cm2

 

so instead of pounds per square inch, its kilograms per square centimeter

 

the conversion is about 1kg/cm2 = 14psi

1 bar = 14psi

 

if you were boosting 14 bar, "youd be driving a nuke!"

I am mate. LOL. Thanks bud. :D

1 bar ≈ 1 atm ≈ 14.5 psi
