I have always wondered why a vacuum pump on a booster would not do the exact same thing as manifold vacuum. It would not even need to be that big a pump as the master vac is relatively small. Only need to maintain about 45 mmhg.

This guy was using an undefined Honda Accord booster. We need to figure it out. It bolted right up!

Do you have any more info for this? Where did you see it?

Found it. So, this guy on Facebook posted these pictures. Apparently, he used a Bosch Gen 2 iBooster. The housing, I get the impression he found an open source file and 3D printed it.

Here is what I have, he says it works better than his GTR brakes!

Looks like a bunch more room in there doesn’t it?
