I've had my BR Alky injection kit (w/ SMC Controller) for just about 3 months.

So I recently decided to check the status of the system by pressing the "test" button on the controller (actually I had my friend press the button while I checked the pressure gauge located at the pipe adjacent to the intake manifold).

My questions are:

1. When the button was depressed is it normal to hear the pump activate noticably? I hear a slight rattling sound.

I guess when the pump is activated while driving you can never hear the pump over the car's engine noise / exhaust?


2. While the button was depressed and looking at the pressure gauge I saw that the needle on the gauge was not steady; it bounced between 100 psi. and 120 psi.

Is this normal?


I just wanted to find out before I call SMC or BR.



Thanks for any help.

 

Not sure about the rattling sound but the rest is normal.

 

i have the same one and i dont noticably hear it, but my car is kinda loud......

 

Thanks for the replys.

I shouldn't have used the word "rattle" to describe the sound, but more of a "rumble".

 

that is all normal.

 

sounds like everything is in order...

 

Yea it's more like a B-r-r-r-r-r
