What's the largest idle air bypass you've used?

(1/1)

77cruiser:
Mine's at .141, too big I think. Kind of noisy at idle.

joeq:
Wouldn't the size be dependent on  variables, such as C.I., and camming (vacuum), ect?

Cliff Ruggles:
I've never went past .120", even for piss-poorly matched cam choice to CID and compression ratio......Cliff

77cruiser:
I think I'm going to drop it down to about .125, I was trying to get the transitions slots showing a lot less, but it's not a Holley is it. ;)
