Right now I am using the vacuum port on top of the supercharger for my power brake booster. I see that some have this port blocked off, and it does make the install cleaner. I would like to do that, but where are you getting vacuum for the booster? The only other source that I know of is the one under the SC snout. The only thing I'm using that one for now is the MAP sensor and the FPR . Can it be used for the brakes as well, or ?? Thanks.

You can't use the one under the snout because that is manifold pressure ( will go to pos pressure when you go into boost) you need constant vac.

You can you the port of the TB or if you are not running a EGR them you can thread that hole and use it. I have used both of them and both work great but I ended up going with the EGR hole being its cleaner.

Yes use the throttle body and delete that EGR, it looks bad anyways The stock fiero tube will fit perfectly on the TB vacuum.

Yeah, cool because I already trashed the EGR! And actually, I had forgotten about that port, and I didn't realize that nipple under the snout was pressure. That would have woke the brake booster up! Thanks all.
