I haven't seen anyone do a stainless tank yet so I figured I'd throw this one up I just completed. This one (the large tank is for the brakes) has a volume of 126"^3, which should hopefully be equal to that of the brake booster itself so hopefully it will double my braking during EOC.
On my 12 minute drive to work 4.5 minutes of that is coasting at one time, it takes a bit of effort to stop even in my 2230 lb civic hatch when I run out of vacuum. These tanks are going in an Integra so hopefully they'll last all the way to the bottom of the mountain.
