I weighed it, after some testing with the scale I used at work, it had more accuracy at a higher weight range. So i weighed the entire governor assembly after i removed material. I have data on weight removed but not actual (small weight), weight. The final mod list was 8 .125 holes drilled and the steel set screw replace with an aluminum one. In car testing yielded just over 6000 on the 1-2, and just under 6000 on the 2-3 shifts. I'll dig up the numbers when im home and post them. This was with a fairly aggressive tv and 28psi.
