Excellent idea. When the vacumn is used up with the engine off, how long does it take to come back after you turn on the engine. Is the delay even noticeable?

I used to run these on a 455 pontiac motor with a 505 cam in it. Same theory only this is made of steel.

It might be interesting to install a vacuum gauge on your dashboard, so you always know exactly how much you have.

Holy crap, I was just starting to draw up kinda the same thing! We do a lot of work on low-vacuum cars and braking systems here at work and I noticed if I was on the highway during stop and go long decel situations I might run out 1/4 to stop because of all the changes in everyones driving speed. I like it!

I like bennelson's idea of a vacuum gauge. We have tons of these at work.

Awesome work and great pics.
Dangit now I have another thing to do. Eoc Switch and this will be going in at the same time.

I don't even notice, but I'm not hitting the brakes as soon as the engine fires up either... I may give it a try, but I'm pretty sure the delay is insignificant.

In order to test it, I'd have to run the brakes completely down (8 presses, at which point I'd most likely be stopped), then fire the engine up and try to brake again immediately.

Another great idea what do you guys eat for breakfast. Like a fuel gauge for your EOC brakes I likey.

I'd like to get a vacuum gauge anyway to help me drive efficiently, but having a second one for the brake booster would be pretty groovy too.

I think a vacuum gauge will be my next mod. Maybe I can mount a switching valve inline so I can check both levels with the same gauge. I searched for a dual-needle gauge online, but was unable to find one.

Can you get an electronically controlled air-switching valve? Then you could have it read engine vacuum while the engine is running and brake vacuum when it's off!

Hrmmmmmm... Got me thinking now!

You could switch it electronically if you had 2 electronic vacuum sensors and an electronic gauge... Then there'd be no vacuum loss/leakover when you switched the valve...

(after a bit more searching) OMG forget that. Electronic pressure/vacuum transducers are about 10 times the price of a gauge.

This is a really good mod! Props.

Love the window sign too.
