And that's absolute pressure...to think of it in boost terms you need to subtract barametric pressure at your location.Normal operating boost for an ALH is around 15 psi, with spikes 17-20 briefly.My Jetta with the new turbo controls boost perfectly with only a couple psi overshoot. My other Jetta with the 10 year old turbo overboosts by around 5 psi.
Of course you are right. But then my question is [ as i personally have little experience with a boost gauge]: will a gauge show real or absolute pressure ?
i run 25 psi all the time..its seen spikes of 40,
Perfect operating range is a nice even 15 psi with a very brief couple of psi overshoot under extreme circumstances ... at the top of this thread you seem to say you're doing 30+ psi.Then there's this thread:Quote from: R.O.R-2.0 on March 13, 2011, 01:52:19 pmi run 25 psi all the time..its seen spikes of 40, So, in the interests of clearing up the confusion... which is it?
