Poll for what vaccum at idle on stock port motor people are getting.

 

on every motor in my black FD, ive only had about 15inHg of vacuum at 750 rpm.

 

uh oh, then I might be introuble...At 750aprox I am at 12-15 not consistant

 

450 - 500 mm HG at ~850

 

Acually my buddies tell me 12-15 is in spec

 

I get 19-21 on a 21,XXX miles motor. was getting 14-15 on my old FD which had compression of 75 PSI all around.

 

11 @ 750. That's what I've gotten for 3 years.

 

19" @ 750 rpm

Keep in mind that elevation will change this number a lot. I'm right at sea level at home. When I visit my wife's parents in the mountains (about 4500 ft), I lose about 5" of vacuum and a ton of horsepower, too!

I'm curious, have you noticed a power difference from the two? (i.e. same boost, but more power)

 

Mine is 16 or 17 at idle ( i cant tell because my HKS gauge goes by 5s)

 

I get 15 at about 700-800 rpm.

 

Well is hard to tell since my old FD had ECU, DP, CB, Intake and Intercooler upgrade. It did feel faster than the one I got now even with the low compression.

 

i get about 15 to 16 at 725-750

 

I get 18" at 700-800 rpm. I have 120,000 on the original engine, and original turbos. Anyone know the vauum numbers for a new/reman engine??

 

I only get around 14 at 750. Only 4000 miles on almost totally new motor.

 

anywhere from 14 to 17 depending on the weather and idle... stock engine with 65k on it.

 

If your milage is true and that is stock engine, that is damn good vacuum you are getting.

if it fluctuates while its idling, thats not a good sign

 

I get around 12-15. The motors got about 60,000 miles on it. But, my friend who had a TII pulled ~11" on a brand new motor, ran strong with no problems.

 

I'm pulling 16-17 at 850 from a Reman w/24K. But I have a Blitz intake, DP, MP w/ HI-Flow Cat, 3" Dual Tip MagnaFlow, 99 JSpec Y-Pipe. And it's an Auto.

 

I suck at math, can anytell me how to convert the XXinHg to what the PFC says at mmHG (or vice Versa).

Direct result of screwing off in high school math courses, don't follow in my footsteps kids

 

19-20in at 700-800rpm on a 55k motor

 

1 in = 25.4 millimeters
1 millimeter = 0.0393700787 in

mine is about 13-15in HG at 850

 

mods? ported motor?

 

i pull around 16-17in at 750rpm on a 77k mile motor.
