[Tony Curcio]

I tried the Ford brake light switch and found it was slow to release. So slow that the 60 foot times were noticeably slower because the car was starting to roll (an inch or two maybe) before the engine was kicked in. This car with this particular carburetor was usually .03 quicker off the 2-step on a hand-release button.

It also seemed inconsistent.

The cure was a high pressure switch for industrial equipment, purchased from the Grainger catalogue. There's even an adjustable switch, although it costs over $400.00. A separate Autometer guage was installed and a red light to let me know when the brake pressure is right. I learned that my application requires about 850 lbs to hold the car at 3000 rpm. So, the release is set for 800.

Make sure the T-fitting is in line BEFORE the line lock, otherwise the 2 step stays on during a burnout. Sounds obvious now, but didn't think of it at the time.
