I do not want to sound like a beginner but unfortunately I am!

I have been reading a lot of posts about the Focus Rs to see what I am letting myself in for, and I would like to say I like what I read!

The questions I have regards the Psi and Bar, basically what are they and what do they do?

Please bear in mind that I have owned 2 cars before I bought this one! A fiesta Lx 1.1 (never let me down!) and my most recent car a Saxo Vtr (80k on the clock and still wants more!) I know nothing about Turbos whatsoever and was wondering what advice people can give me on the psi and bar readings.

Apologies if this post makes no sense!!!

Cheers

the psi/bar is the pressure or force of the induction from the turbo to the inlet manifold (i believe - sure someone will correct me if not)

 

I just read that PSI stands for Pounds per square inch so I am none the wiser......

How do people raise their psi on the car?

 

in real lamens non technical terms a turbo'd car runs boost.

this is measured as boost pressure which can be measured as units of PSI or BAR (exactly the same pressure units you use when you pump up your tyres)

The amount of boost pressure your car runs will be pre set at factory.

Its a misconception that the higher the boost pressue the faster the car. Its not quite as simple as that but with the correct modifications elsewhere (fueling etc) an increase in boost pressure is a great way to make a turbo'd car faster.

 

Buy a bluefin form superchips that will rasie your boost.

That also take care of fueling ect.

O and for every 14psi = 1 Bar of boost
