Thinking of picking one of these bad boys up, wondering if anyone is running one, specifically on a NA build.

im doing or going to....get one. my LS3 416 jsut eats oil. I think it is blow by, but im still working bugs out. the PCV is all custom..
I have hooked it up 70000 different ways, and so far the best way has been...
i took the valley cover and modified the outlet tbe to be more open to release more air. I now use an external valve to a catch can. The smoking on accel and decel has greatly improved. a 800$ vac pump is the last resort. They also scare me becuase you need to run one around 17-19. To much vac and you can starve your bearings and smoke your crank

I just talked to Greg, the gentleman that makes these pumps. He is warrantying them on GEN III and GEN IV motors! That was kind of a hang up for me, I wasn't about to drop $800 on a pump with no warranty.

I have one of Greg's setups on my SBC 406 in my '69 Nova. When I built that engine, I opened the rings up quite a bit for nitrous. It allows quite a bit of pressure into the crankcase, and I was blowing my oil dip stick when I made nitrous runs at the track. Now, with the vacuum pump I have zero oil leaks. I hope to get it on a dyno to quantify the power it is supposed to add. I have driven my Nova quite a bit on the street, and the vacuum pump is holding up just fine. I have considered one for my FRC also, but can't really justify it.
Here is a picture of my setup that Greg posted on his site (the first two pictures are my engine): http://www.gzmotorsports.com/sample-installations.html

I have been wanting a vac. pump on my car for a while. The problem is I dont have a mounting spot because of the supercharger. Jegs has an electric vac. pump kit on their site. Anyone tried this?

I fabricated an auxillary vacuum system using an electric vacuum pump in my 77 Vette but not for crankcase evacuation but for running all the vacuum systems. The engine was a bit too radical (Lunati cam Brodix heads etc) and didn't develop enough vacuum to even lift 1 headlight. Worked great, no problems, just was fairly loud when I hit the switch to turn it on. Probably wouldn't last if you ran it full time. I only had to turn it on for short intervals.

The kit I posted has an adjustable bleed valve, so you can set the amount of vacuum. If you can set it to the proper level I wouldn't worry about it starving the bearings.

I have some pretty sweet plans that should work, based off the system that I saw yesterday. I need to relocate my battery, unless I can find a good spot for 2 reservoirs. One for an oil feed for the pump, and one to use as a catch can to put the condensed oil vapor. I could go further and make a recirculating system, but I want to try it with 2 tanks first. I need to find an economical way to move that battery. Summit has a kit that is about $80, I just want to make sure the box fits one of thise side wells in the back. I also need to know if I can ground to the frame with the battery's negative cable.
