Boost gauge question
« on: 07 September 2009, 17:25 »
Just seen Patch's interior pics and noticed that his boost gauge sits on -20 on norm temp idle. Is this right??

When on norm temp idle mine sits under the -20 mark more like -18. Could this be the reason why i'm not peaking and holding boost properly maybe  :laugh:

When the car is off, the needle sits on 0 like normal so never thought there was an issue...

HELP PLEASE!!

A car that's running spot on should sit at 22 inhg at idle speed,anything less than this and you will have a boost leak somewhere.As you can see mine sits just below the 20 mark,so i have a slight boost leak.

Cheers for clearing that up Patch...and i've just realised my mistake... :laugh:

Mine is actually sitting on 22in hg. I thought it was 18 cause it was lower than 20. Never noticed that it was going to 30 not 0 :laugh: :laugh:
