Ok, general question.
I want to lock the converter in 2nd gear. I have a bb6765 CEA turbo with .85 hot side (big hot side style) and if I lock the converter in 2nd with the transmission in "D" it will shift 2-3 at 5400 rpm.
With the gear split in a 200-4r with the converter locked that pulls the rpm down to 3500 in 3rd gear. That rpm is low enough that you can hear some minor compressor surge occurring and the motor is noticeably below the power band. The surge clears up at about 4000 rpm, it's not a terrible amount of surge, but you can hear some audible fluttering.
Has anybody else had this issue and what did you do? I plan on trying to manually shift the car up around 5800-6000 to increase the 3rd gear shift RPM (car has a quicksilver shifter, so I won't be "walking on egg shells" trying to shift it manually) , but I could also just leave it unlocked until it's rolling faster in 3rd, but I think the car pulls noticeably harder with the converter locked.
