BAP question

[mrose75]

I installed BAP, 80 lbs injectors, Stage V Steggy port, and SCT 2600 MAF yesterday. Now I have a strange sound coming from the back when the ignition goes to the KOEO position, which I assume is the BAP or what it's for in the stock pumps to do. While driving there is also a persistent buzz/whir coming from the rear, again I assume this has something to do with the BAP. Thoughts/input? Thanks.

I read on here, other people say the BAP buzzes when it's working.

Man, if it's that loud....:nonono: That's annoying. I may have to skip the BAP work around all together.

Anybody else have input or is that it? BAPs are loud?

Great! So I have something funky going on?

They do buzz, but typically with car running and the bap behind the trunk panels you don't hear it.

I dont hear mine

I can hear it at idle. Could it be my stock pumps being worked to death? I added 80lbs injectors. It's coming from behind, but with music or the windows down I don't notice it.

have you removed your truck panels to see if it coming from the bap or the pumps?

Doing key on after the car sits I can hear BAP kicking in the pumps bringing up the pressure but that the last I hear from it.

I haven't removed the liner, but with my head in the trunk the buzzing seems to be coming from the where I mounted the BAP.

I here this as well, but the buzzing continues. It's almost like that buzzing you get in speakers.

How do you have the bap wired up?

 

[TRBO VNM]

If it is wired correctly and works and you can't hear it, the exhaust is probably drowning it out.

I'm pretty sure I wired it correctly. It's not that hard. I used this: http://www.svtperformance.com/forums/how-230/244875-bap-wiring-upgrade-installation-directions.html

Are you saying that it should be heard buzzing?

Yeah it shouldn't be that hard, but plenty have messed it up. And yes you should hear a buzzing sound from the bap. I can turn ignition key on (engine off) and put my ear by the driverside tailpipe and hear some buzzing going on. When the engine is running though, I don't hear it. So no the buzzing sound shouldn't be louder than the exhaust!

Yeah, when the radio is on and I'm driving around I can't really hear it. But no radio, yes it's prevalent.
