After you get it all figured out, you can stall the right converter VERY high with the std 2 front, 2 rear setup. Believe me, I chased it for awhile.......

I figured it had to be the auto cars, as with a stick all you need is enough front brake pressure to not roll, the less the better. Thanks for the explanation.

Several years back I put aerospace disc brakes on our Nova. I went with dual calipers on the back for more holding power when staging. It was the best thing I ever did. The car went from really having to push the brake pedal hard to stage at 3000 to where with just a little pressure on the pedal I can take It up as high as I dare without it trying to creep at all. The only problem I then had was that the master cylinder didn't have enough volume to have a good pedal on the first pump.I fixed most of the problem by going to a big bore (11/8) master cylinder.It then had good brakes on the first pump but It was still about 3/4 of the way down. ( Not good for finish line braking) I finally put a 2lb residual valve in the brake line going to the back brakes and now I have a pedal nice and high. The back discs don't seem to have any more drag than they had before. Hope this might help someone. Bill

How are you guys plumbing your brakes? If you look at the Aerospace brakes instructions for plumbing dual rear calipers. It looks like they are saying to hook the front and rear ports together with a tee's. Are you guys doing it this way? I am sure it works but what happens if a line breaks. Seems like you would have no brakes instead of weak brakes.
