See if there is space to mount this on the frame in front of the motor down low. These motors like a good air supply to help keep cool with the little diapham and motor running. If there are in dead air they make louder noise. If you can get a air flow to the area, you can mount sound deadener also to direct the sound away from you.
Does your motor have a big camshaft? What I mean is loping and rough idle with only 10-14 Hg of vacuum? If your motor has a higher vacuum and you are running a double vacuum booster, you should need the vacuum pump to run the system. Only a vacuum gauge inline will tell. I know it's not pretty but the diesel assist pumps work great last for 10-15 years and you never hear a noise. Hydro is the other way. How's China??? Rick Lake
Rick, good points, I'll discuss these options with the installer to see if this can be done on my car. The issue is when I turn the ignition key, the booster pump kicks in, makes a racket and then stops. In traffic when I apply the brakes the sound is audible and troublesome for me. Thus my question "is this normal", apparently so.

China is awesome and is the place to be if you want to establish a footprint for your business. Free land, tax incentives up the gazoo, inexpensive labor with a great work ethic and in most parts good infrastructure development for product distribution. The tourists spots are also good too, come on over and we'll share a brew. John, AKA, tin-man
