I'm not seeing any electric units capable of moving the volume of air required to do the job, unless you're just trying to make power brakes work. Maybe my search skills are lacking.

As per GZ Motorsports:
"At best the electric pumps I've tested are about equivalent to a pan-evac system. I'm not current with the latest electric pumps because I abandoned that approach based on our testing. The Pontiac pump which has a lot larger motor than the Corvette pump would run the battery down very quickly if there was no alternator to keep the it charged. Again most of these pumps are designed for low air volume and an oil free environment, they might work adequately for a while, even as well as a similar to a pan-evac system, but they won't likely last a long time."

This was a few years ago, but I don't know that anything has changed...

Except for this which I know has been used on Pro Stock motorcycles...

If the results don't match the theory, change the theory.
