hi any one know what vaccum leon cupra r should run on tickover.mines at -8 does that sound right
I'm sure mines -20 or -25 on idle but mines not a R
mine same -8 and its a lcr
LCR 9psi vacuum
thats boost turbin
mines -20 to -25 on an LCR for what ever vacuum is measured in
is that remapped?
Yeah stage 1.
so it must be more vac on a maped 1
Mines not mapped and I get the same vaccum
my gauge dont go that low?
18 inHg or 9psi vacuum.
I'm mapped and its -8 on that last 2 Boost guages i've had on.
Mines around -22 as well.
Those at -8 you have a leak
Just think, if you are losing vacuum on idle, just how are you loosing on boost
I have logged extensively and this no evidence of a leak on my car.
I'm sure there was a thread on this not long ago. The conclusion IIRC was that a vacuum lower than approximately 20inhg (i.e between 0 and 20inhg) then you have a leak somewhere. Apparently the air con might make a difference to the reading if it's switched on. Around 20inhg or higher is normal.
Interesting, i will trible check my hoses.But if there is a leak its minor, i have logged boost at least 10 times over the past few week and everything looks normal.
Maybe if we could get more peeps posting what vacuum they are running at normal idel(not choke or with aircon on) for the LC and LCR we could get a better picture of what peoples reading are.
get posting peeps.
When you say -8, do you mean -8inhg or -0.8bar. What units are you using? Because -0.8bar is 23inhg which is fine (no leak).
