not always true...by flashing the converter it takes longer to get in the upper rpm range so you are making less power off the line...if you are brake stalling it at say 3000 u are closer to the upper rpm range...

my car has always liked to get brake stalled as high as possible without pushing though the front tires...it gets me 1.38s Cam Only

Again, it's whatever works for you. I tend to spin when I stall it up, but dead hook when I flash from idle. As stated above, when you flash it's going to be softer as the stall climbs up the rpm band from a lower starting point. It seems like I get better weight transfer flashing than having the drivetrain pre-loaded.

with proper tires and suspension setup i bet you will 60ft better brake stalling it up over flashing it...

Its not about how fast the RPMS get up there. Its about torque multiplication. The higher you stall the converter the less torque multiplication is going to effect it.

To put it very simply lets say you have a 4000 stall with a 2.6 STR. The only time you will truly take advantage of the full effect of that 2.6 STR is when you flash the converter. Say you stall it up to 3000 before launching that 2.6 STR is becoming more like a 1.6 STR.

My best run was on that technique, Yank ST3500 also w/ MT ET streets and 3.42 rear.

i have a 4c converter with stock suspension other than control arms and mt et streets at 11 psi. I hold it at 1500 and flash it and it will break them loose almost every time. When it does hook it hit 1.60s
