What do you guys with street ported engines set your idle speed at?

I have a couple of friends that set around 600 rpm. Sounds kinda mean but is this ok on our engines?

I thought 750 was the normal and 850 for street ported engines...

 

Mine sits around 1K but is pretty lumpy.

 

Before the Apex seal broke mine idled at 750 in neutral and 650 in D
now It idles at 450<>500 in D and stalls if I turn the AC on.

 

mine's set around 1k also. smooth though. never thought about lowering it. does it sound meaner?

 

I also have a Petit ECU in it which does some funky stuff to it. I think the warm up cycle has an idle RPM and when it's warmed up. I would think an idle too low could bog/hesitate. Often, mechanics will bump up the idle to hide other problems (vacuum leaks, etc).

I love the lumpy sound of my rotary when it's just under 1K. It sounds like it has a big cam in it : )

 

I have my idle set around 900-950 or so. Mine seems to idle fine there but it gets a bit lumpy if I turn it much lower. I pull about 400 mmMg or so at idle and from what I hear that is about right for a healthy, mildly streetported motor. I can see if your motor is a bit older or you have a more radical port you would have to bump your idle up so the engine won't stall.
