Building boost at the line Taking the car out for the first time ever next week. How much boost can I expect to build with the foot brake? I have the 3600 stall. Sad its taken this long to get out 
Mine sees around 3psi on the footbrake before it pushes. On the 2 step without timing changes its around 5-6. I havent tried holding it on the 2 step for more than a couple seconds though. Going to the track tomrw.
mines a 3600, i can get 11psi. Your rear gear will affect it, and whatever trans you have the 1st gear ratio. If you got like a 4l60e w/ 3.73's you probably wont make much before spinning the tires. I have a glide w/ a 1.80 first gear and 3.50 rear gears...helps a lot.
