1.01Bar
Posted: Mon Apr 18, 2005 8:18 am
Last weekend i took my G out for a spin with the works pressure/vacuum transducer plugged up to the diagnostic equipment (£3500 worth!) It self calibrates when you first plug it in so that what you are reading is above or below the atmospheric pressure for that day (much like a map sensor does when you first key on).
I got 1.01Bar (tad over 14.7psi) at 6500rpm and 530mBar of vacuum at idle, Does this sound right??
My engine spec (a far as i know) that would affect boost is 1272cc, full blend, fat K&N cone filter, 76mm induction pipe and collar, toothed belt, front mount intercooler, samco pipes, larger throttle body and a ported gt inlet manifold
I had 12psi on PSD's gauge the last time i was up there but this was before i had the pin holes in the front mount welded up so it was leaking boost.
I'm particulary intersted in the idle vacuum as this seems a little high??
What do your cars read??.
