I was just wondering what the normal idle for a ported motor should be at.
I have a PFC and its set to 1100 ish.... but when I drop it down to normal
750 or so... it sounds like its going to die out.
For the people with ported motors what idling are you guys set on?
Is this normal for a little bit higher idle on ported motors???

Thanks!!~~

 

900 is where I have mine... 750 yeah it acts a little weird..

 

1200 is about right for a race port. Also depends on your injectors too

 

I have mine around 900-1000rpm it idles best there, anything lower and it'll want to die out. What's your vacuum at?

 

my Vacuum???? YOu know what??? I have no idea what it is at idle....Damn....
I think its about time I should take care of that car.....
What is the vacuum supposed to be at???

 

Vaccum should be arround 11-14 depends on how much the ports are. Idle should be at 950-1000 rpm, also so you might have to pull some fuel out at idle in the pm volts on the PFC.

 

I have a street port and I idle at 850. Sounds great there, but at 750 it shakes the entire car and sounds like it's going to die. So for a big port, I would guess 1000 would be about right. I would just make it idle as low as at can without shaking the crap out of the car.

 

my street ported motor dosent like much below 1000... im at 1200 right now, but i gotta tune it and get it down to 1k

 

also take a look at the hows my idle thread i posted at the top of this page, it will give you an idea where people are at.

 

Sounds about right. I ported the hell out of my motor, with some serious overlap. At ~1000 rpms, I am seeing around 13-15 inches Hg vacuum. I

t all depends on the port sizing. If you did not port the motor yourself or receive pics of your portwork, then dont make any assumptions.....I have seen some "streetports" when we break apart motors at the shop and sometimes they look like they were ported with a damn toothbrush.....

 

i have 4-5inHg of vaccum, sometimes 8-9inHg when its warm, idling at 1300-1500rpms

 

1100 rpm idle with 15in of vacuum.

 

You left out on minor detail.......el half-bridge

 

i seee 15 to 18 vacuum @1000 idle
street port motor

 

I pull around 12inHg at idle at around 1k-1100 rpm with a big street port.
