Have you ever wanted to own an electric car? or have you ever wanted to drive a Porsche 911? I wanted both, so I decided to build one. This blog is here to document my journey as I convert a 2002 Porsche 911/996 Carrera 2 from a gas guzzler to a completely electric vehicle - not a hybrid!

Vacuum system test

The vacuum pump, reservoir, and gauge arrived this week.  After a trip to Menards for some gas fittings, I was able to test the system as a complete unit before putting into the car.  Here is a quick video of the completed contraption.  It takes about 2 full minutes for the pump to reach the shutoff point with the reservoir attached.  It turns out the pump has an automatic shut off at 10 in Hg so I don't need the additional vacuum switch.


  1. Hi Kurt,

    I contacted Dorman about this pump to supplement my brakes and they didn't recommend it at all. It's built to run accessories not the volume needed for braking.
    I'd suggest sticking with the other vacuum switch and a Hella UP30/32 since you're going full elec. Bit more work as it'll need a relay and other bits but I think it'll be safer in the long run.

    Check out this webpage, he's supplementing a regular setup but same principles.

    Hope that helps.


  2. Ray,
    Thank you for the feedback! The pump did seem a little under powered when I tested it. I will look at your recommendations and find a new plan.

    Thank you very much for the heads up!
