first 300 miles on Malloy reman showed 16-17 in. Hg;
after 300 miles, showing 18-19 when cold and solid 20 in.Hg at 900-950 rpm on VDO 2 -1/16 gauge.

My original engine never showed more than 18 when I bought it at 30K miles, and my 1st reman (which had housings used in a prior reman) never showed more than 17 in. Hg.

I changed oil at 300 miles and boosting briefly to 10 psi at about 4K rpm.


Curious as to what others got with their reman?

 

I only pull like 14-16hg with my reman engine.

It's 7k miles old and has 115 psi compression across all front rotor faces and 115 115 110 across rear.

Vacuum doesn't always mean much :P

Granted, I have a crappy autometer boost guage, maybe it doesn't measure right

 

Mine is almost identical. Just about 20 in Hg. at a steady 950 rpm idle. Sounds like you got a good engine based on what mine put down on the dyno in near stock form.

My old engine was showing ~16 in Hg at about the same idle, just for reference.

 

My 20,000 mile reman pulls 18-19 at idle. The old, tired motor showed about 16 before it lost a rear apex seal.

 

my engines got about 14k on it, maybe less.... pulls about 15.5 at idle... I think it has more to do with my vaccuum lines than anything else tho

 

Well my engine pulls around 10 in at that rpm, but my engine is very strong.

 

Errrrrrr......??????

 

unless your motor has a big port pulling such a low vacuum is not healthy.

for another reference, I am 16-17 around 850 RPM (original motor at 59K though not a reman)

 

Yes, forgot to post the rest. Large port and I really don't idle that low. At 1000-1050 rpm I get around 14 in. But the motor has only 4k miles now and is running great.

 

When my vacuum leak heals itself I pull 19 at 850 RPM, and when it acts up (usually) I sit between 16.5 and 18.

 

I pull 18 at 800-900 idle on original engine with 57,800 miles.

 

I pull 16ish at 800 rpms 86k original engine

 

Vacuum is just a quick indicator of health like taking your blood pressure. 11 to 20 your still kicking but anything below you may have one of your rotors on the fabled bananna peel.

Anyway if you have a good idle and the car pulls strong you can stop worrying and just drive it. However be sure to: run the proper boost, keep the tank full, add some 2 stroke oil, change the oil each time you change you underwear, oh **** don't forget the fuel filter, never use low octane, etc...just one slip and your vacuum will surely be doomed

 

Word. MMO is good stuff.

 

18+ inches (460 mm Hg)

Engine has 4k on it. New rotors/housings/etc. and 3mm seals.

 

16 at 750rpm and mild streetport. Are most of you guys running 850-950 idle?

 

13 on a big street port at 900 rpms

 

20 on vod with street port

 

-470mm on PFC
reman has 10k on it

 

Less than 10k miles on the motor with a "large streetport," I pull around 12 in on the Autometer at ~1,000 RPMs, but the Autometer reads slightly higher than 0 when the car is off, so it's probably closer to 13 in. Previous owner removed the BAC Valve and it was re-installed last Friday. It needs to be adjusted a bit more because the idle is still fluctuating too much.

 

i pull about 9-10 in at 800rpm. i have an MZM race ported motor and the motor is healthy with 3000 miles on it

 

hmmm, just put in a catless midpipe, now im pulling more vaccuum.... anyone know what .6 bar translates to?
