Standard boost 225??

[godber225r]

Done some searching for the past half an hour and found that the LCR 225 has about 14psi standard boost? that right?? But what does it vac at??

I am fitting a PSI boost gauge soon so i need to know the figures so i know everything is good and its fitted right. And too see if my car has any boost/vac leaks!

Thanks

around 20-21 just on idle but when driving and foot off accelerator it goes up to maybe 22 23

standard lcr boost around 14 peak and drops to 12psi

On boost mine peaks at 15 but holds at 12
On vac at idle its 17 when driving about 21

sorry to bring this back up, I have just fitted my boost gauge and looking at the figures seems to be boosting fine just wondering about the vac though.

On idle mine sits roughly 22 and when driving with foot off accelerator will go to 30.
From other peoples replies seems to be off, is there a problem, and could someone explain what the vac actually is, i'm not sure thanks.

 

[Lodgey180]

it will do coz the engine isnt using fuel to keep it running.. mine is the same

i don't get that though, as mine sits at 30 when i lift my foot off the accelerator. Other people are saying theres sits bewtween 20-22. Mine also sits at 30 on idle when autochoke has disappeared. I have just a cheap autogauge from Halfords which i wouldn't expect to be true but looking at this it could potentially be fooked and answer an issue i'm having at the min'
