Jim 2 Posted June 2, 2004 Mine usually sits about 13 on cold (as obviously the engine is idling a little higher) and about 17 when a bit warmed up. I dont know what those figures correspond to, but thats what my boost gauge reads anyway! *edit* And yes, that is labelled up as VAC... What kinda readings should one expect from idle Henny?

Henny 0 Posted June 2, 2004 that's a vacuum reading Jim... 8) (normally in mmHg) When at idle, you should be getting a vacuum reading as the engine isn't using any boost, any that is made is being either sent back to the 'charger or vented to air if you've removed the boost return pipe... as you press the throttle, this should decrease to 0 and swing up the boost side of the gauge, maxing out at around redline with the throttle wide open (known as WOT - Wide Open Throttle) 8) Quote Share this post Link to post Share on other sites
