I have never actually seen an electric pump work for this. It's not the psi that is a big deal but the amount of air they can flow. I saw someone try a pretty big electric pump and it just couldn't keep up. Flow rating is gonna be your limiting factor for the size pump you are describing. Think of it like this that small pump will pull a vacuum on a coke can pretty fast but not a nitrous tank. An engine just produces to much air for a small electric pump like the size your describing.

You can also if your running exhaust without cats, put check valves in the header collectors and they will pull vacuum if you connect one to each valve cover,, totally not smog legal, and some tracks may have issues if they notice.. (In a rollover you can dump oil in the exhaust... ) But it worked really well back in the day.. A lot of high performance boats did this as well.. But bad for obvious reasons.. LOL It also can work with one after the turbo but the valves have to be good stainless ones or the heat will kill them.

Morose makes a decent kit. It's just call a morose crankcase evacuation kit.
I personally have use the mighty mouse canister and it worked great. I'd recommend that before I went the exhaust evac kit. I've seen the exhaust evac kit work good and not work for **** so it's a crap shoot especially on a street car.

The electric pump idea is a non starter. A big enough one to do anything at WOT would be far too much at low speed. This would require a controller of some sort. This would need a sensor of some sort. long story short, you would end up with a overly heavy and complicated system in place of a vacuum hose. When in doubt, simple is better.
