My 350 idles at 500 RPM's while in gear w/ no accessories running. I thought this might be a little low, but I'm curious as to what the rest of yall idle at in gear w/ no accessories?

What do yall think is too low? . . . . too high?

I know it's kind of a boring topic, just wondering. (kind of like my MPG thread )

 

With the bigger injectors, my car likes to idle at ~750, below that it's hard to get the pulsewidth to keep stoich.

 

Yeah mine's right at about 750 too, bbc injectors though. That is of course it WILL idle there if i ever get it running again

 

My basically stock 305 TBI idles right at 650 RPM.

 

My Tach says 500 RPM... But when I hook a laptop up to the cars computer.. It says 650 RPM

Will I ever find a tach that is accurate?

 

Mine is dead on.

 

Mine is same as yours lol.

 

I think that my car is around 800 or higher its kinda crazy for some reason it likes to idle rely high all the time even when its hot! could it be my 160 stat?

 

hmmm when warmed up etc ... in gear hmm maybe as low as 600 sometimes .. most of the time 650-700

 

I tried the 160 stat for a while ... bad bad idea .. my engine never warmed up completely ... your engine may be running in "warm up" mode all the time

 

my extremely out of tune 350 tbi runs at a low 1250 rpm if it's warm, 2000 if it's cold, maybe the tach, maybe the tune

 

900 when cold, 525 when warmed up whether in Park/Neutal or Drive. A/C on bumps the idle to 600 in Drive, but when you shift into Park it goes to 1,000 and stays. .

 

Tach says 400~450 rpm, datalogs say 600~625.
