Hi all, just fitted the above along with oil pressure and water temp (yet to be wired up). My boost guage needle doesn't sit at 0 when switched off but goes up on boost and down on vacuum. With it not sitting at 0 does that mean I am getting inaccurate readings :confused:

 

Is there any way of adjusting the needle to 0 at all, my guages are made by Motor Sport.

as long as when car started vacuum reading is minus then when accelerating the needle passes the 0 and goes in to positive boost+

 

for eg whilst car running -20 on full boost 12 psi

You just need to be aware of the air pressure.

 

I think normal is about 1000 milli bars = 0 on guage

 

I think the pressure might be High just now, just checked it is 1022 mb (BBC Weather-online)

 

That would move it

Thanks for that guys.

With the pressure being high, that would put the needle into + wouldn't it

mine is actually in -

 

Greg, yes it does go to -20 INhg and to just over +12psi (got boost jets at 1.2mm for now ;) )
