OK, we have an AIR pump right? If not, I'm such a newb... But anyway, occassionally I'll get a squeaky belt after starting up for a couple of minutes. It stops immediately when the AIR or EGR stops running.

So back on my old 5.0 engine, we just gutted the air pump to theoretically free up a couple of HP. Can this be done on the LS1? I have LT w ORP so I'm not worried about the emissions thing.

Thanks in advance.

The air pump is electric on the ls1, Its under the driver side wheel well/bumper. Your A/C has a seperate belt might be that or check your main belt.

might want to check the idler pulley as well.

Thanks guys, but this gets me to thinking that the squeaking (its reallly more of a whirring...) might be something screwy with my AIR pump.

Can these things be disabled? Will it even matter if I do?

Is this something new that it just started doing?

All the AIR pumps on these cars tend to be pretty loud, making that "whirring" sound at start up. I've had 3 LS1s now that all did that.

If it bothers you, the system can be removed rather easy. Many people do it.

Its done it for a couple of months, and not every time. It does bug me, although I like to imagine its from a roots blower sitting on my intake... ha ha.

Yeah, just saw the AIR system removal post. Good stuff, may be in my future.
