What do you currently idle at with your p600b, or, what SHOULD i idle at with mine? Mods are in my sig. Im afraid mine is a little low, it is below 1000. Thanks

 

About 825-850 according to the scanmaster.

The blower isn't going to effect idle at all. My car idles at 850 with a cc306 cam, and D1SC.

A stock car will idle somewhere around 750 rpm.

 

The stock computer sets the idle slightly higher before it warms up, once its warm you should be right about 800-850 range. Shouldn't be a problem and the blower shouldn't have affected it at all.

The tach might be off too- my laptop says idle is at 850 while the tach is reading closer to a grand- keep that in mind.

 

My P600B on my LT1 impala idles at 950 by the tach, but reads 850 on the laptop.

 

800-850rpm LT4 hot cam and p600b

 

Your car may idle higher because you are now forcing air at the throttle body. If the IAC motor is already closed all the way then your idle will go higher because of the extra air that is being forced past the throttle blades. We adjust that on aftermarket throttlebodies with a set screw.

BTW, mine idles at 1000 RPM... I have adjusted my throttle body though..
