I Forgot to mention......

For any that are going to be running a vacuum pump, make sure the seal on the oil cap is good and the O-rings on the dipstick are excellent (Or just put New ones there cheap)

Also, Have the bleed of valves set to between 10"Hg-14"Hg of Vacuum, You can experiment in that range, If your sucking up a pile of oil to the catch can bleed off more pressure.

Moroso sells the bleed off valves, there# 22637 (3/4"), 22636 (3/8") and one that mounts on the line to the pump is # 22633

Dry Sump systems can run as high as 22" Hg of Vacuum, ...IF... that is your set up.

Even small amounts of Vacuum STILL have its benifits.

I know this is an old thread, but I just had a question about adding an electric pump.

I've seen the ones they sell for $300, but I was wondering if something like this would work?: http://www.sparkfun.com/products/10398

I actually did run an electric pump for some time. The reason I did it is because my old motor began to wear out and the rings didn't seal so well anymore at wide open throttle and I would get some smoke out the pipes caused as a byproduct of blowby.

I ended up using an electric smog pump off an Fbody car to pull the extra gasses out of the crankcase. I used an air/oil separator inline to keep most of the oil out of the pump. I routed the output side of the pump into evac tubes in the exhaust pipes that I welded in just after the mufflers (and just before the exaust tips).

I went the extra step of modifying the bin that the ecm used. I changed it so that the economy shift light would just come on right at 4k rpm and stay on at any rpm above that speed. I used the output on the ecm for the shift light to energize a relay for the pump. So, anytime the rpm exceeded 4k rpm the pump would come on and evacuate the crankcase.

It controlled blowby well enough that I would not puff smoke at WOT.
I abandoned the setup when I swapped in the new motor. I still have it though. I can locate all the parts and if your interested we can work something out.
