What is your intake manifold vacuum (inHg)?

What is your intake manifold vacuum (inHg)?

How much do you get when properly tuned, idling?
Toyota specifies minimum 15 3/4 inHg

What do you get?

21



But the motor has less than 5K miles on it...

how about you just say what yours is, and we avoid beating around the bush.

 

[Spike Strip]

LOL !

That's cutting to the chase !

Sorry dorcom, but I laughed at brian's comment.

I don't know mine. Never have hooked up a gauge to it. Hoping to change that soon.

I am at 16ish, should be higher. my BMW that I just rebuilt the engine 30k ago is at 21-22ish but I doubt the cruiser will ever be that good.

 

[Pighead]

It depends...altitude, cam, timing, valve lash all affect vacuum.

 

[Lugal]

19-21 at idle. 25-26 when off the gas coasting downhill. Less (much less) when standing on the skinny pedal.

Vacuum

Pretty much inline with Lugal on my gauge readings.

I have a vacuum gauge installed. I have 20- 21 at idle at sea level. Goes down at altitude. It's approx 18-19 at 4000 feet. At 60, at sea level, on flat ground no headwind it's between 12-14.

Thanks for the adult* answer!
You're like me! Vac gauge installed

That is about what I get in the Bay Area (sea level) 20-21 @ idle.
Have yet to climb up a high mountain to see what's it up there.

Ranger, Can I drive up Mt. Shasta? I got 4 wheel drive!

Thanks again.

*PS Some seem to confuse vac (inHg) with phallus length. Oh well a male thing...

Ehm, my dick in inches/Mercury? Or my "bush" sucking power?
You confuse me, man!

Thanks for the "to the point" answer!

Me too! ROFL!
See my reply to him...

 

[Hulsty]

I went from 3ish to just over 20 inHG by fixing all the leaks!

 

[1911]

19-20 at idle at 800' elevation.

 

[Dynosoar]

Vacuum SUCKS!

Dyno

 

[jc43089]

So if I'm at 16 with timing set right on the BB then I need to be finding more leaks...better get back to the bat cave!!
