Any idea why a car i saw the other day (Import TT) was reading -7 to +7 on the boost gauge compared to all the buying advice saying -14/14?

its the other way round -7 to +7 uk

-14 to +14 j-spec well thats what mine reads so with the japanese cars you get more boost only joking :D its read differantly over there

i think 14psi is 1 bar

but thats just a wild stab in the dark

its the other way round -7 to +7 uk

-14 to +14 j-spec well thats what mine reads so with the japanese cars you get more boost only joking :D its read differantly over there

 

 

am sure my jap car is -7 to +7

its the other way round -7 to +7 uk

-14 to +14 j-spec well thats what mine reads so with the japanese cars you get more boost only joking :D its read differantly over there

 

 

Wrong way round.

Wrong way round.

 

thot so

Definately wrong way round, mines a j-spec.....-7 +7.

I think you'll find that thanks to the Japanese being such a zany bunch they like they are keen on the metric system so your pressures will be in KG per sq cm rather than lbs per sq inch, it's definitly kg/cm on the oil gague and I cant quite make sense of the x100mmhG on the dial but for reference 1kg per sq cm is roughly 14psi

 

on the other hand I could be completly wrong.....

My old fellas old Zed was a UK and read -14 to +14.

am sure my jap car is -7 to +7

 

 

yep alot of help i am vica versa doh :confused:

My J-spec reads from -7 to +7 in units of x100 mmHg, also known as "torr"

 

There's a pressure conversion chart here:

7 x100 mmHg = 13.538 psi

 

Class dismissed :dance:

Yours a re all reading? Bloody hell fire. Must only be mine.

yeah dude my JDM is -7 to 7 (but thanks to JWT it goes off the scale to about 10 ;) )

mmHG=mm of mercury ;)

how is boost pressure measured in mecury then mr. duff? :)

vacuum is measured by how many mm of mercury it would pull in the olden days in a test tube type thing ;)

Which i beleve was called a manometer

its mm of mercury -7 being while under vacum conditions +7 while under boost

 

think of a "u - tube" manometer and you will get the picture

this one was not right to the far left, about one 'click' in, took it out, came back after giving it a spank and the engine was steaming big time...oops, sed id have a think about it...see ya!
