Shift point changes?

[junkbrick]

I have a Century (Kurtz) trans brake in my 200R, and ever since installation my 1/2 shift is lower than desired when leaving off the brake (approx. 4200 rpm 1-2 shift, no to little tire spin, and the convertor gives me 3800 stall @ 15-18psi, and closer to 4000 anything above that in boost...) I like to leave around 10-12 psi (3500 rpm) on drag radials and am very consistant in the 1.52-1.55 60' ft. If I foot brake, my shifts are closer to 5200, almost the same 60' time, I will be going through the tranny in a few weeks to get me ready for some late summer racing...the car has fallen off in its et since the trans brake install, and all I can blame is the rather short 1-2 shift. I would like a 1-2 shift to happen around the 6000 rpm area. Any ideas will be greatly appreciated and I will be happy to give you all any more info on the tranny if needed. I am off to work, and will check back this eve.

Thanks in advance,
Reed
