boost gauge reading at idle ?

[hoopsbhoy]

Why you being so tetchy man, you plainly have it plumbed wrong. And 5psi is not standard boost either.

You should be running arounf -17psi on idle for a start

plumbed wrong not by me bought the car and it wrecks my head everything is wrong and spending most of time fixing it instead of driving it...thanks for the help lads.
its reading -.6bar at idle and boost up to .5bar

[Johnie]

No problem, I hope you mean bar and not psi.

[20vees]

yes you know it ha ha ha ill edit

-17psi??? roughly -1.1bar at idle? not a chance, thats way to much should be -.6, -.7 thats about right

id say the vacuum pipe is plumed up the wrong way for ya lad.. go take a vacuum from the intake manifold and run it to your gauge..

@ topdog.. ya it defaintley shoudnt be -1.1bar as you don't read bar in vacuum you read bar in pressure smart man clap clap for you.. are you a mechanic ?

[topdog]

Vacuume is the same thing you muppet just on the other end of the scale so you read it as a negative figure pressure is above 0 on the bar or psi scale and vacuume is below 0 so read as a negative figure which is measured in bar, psi, can measure it in mmwg or even kPa if you want to. Doing instrumentation for the last 4 years dude wrong thing to be trying to correct me on. Clap clap for you

[topdog]

And just out of curiosity, what did you think was the unit for measuring vacuume??

[pauliesx]

lads lads lets be nice here hee hee...

[damo1]

so your telling me vacuum is the same this as pressure?? so when your engine is on over run it acts as a hoover sucking the air into the cylinders when on closed throttle,. is that how you also describe pressure??
