SR/219/190s/PT converter and almost any gear will work. I've gone a best of 11.62 and a best mph of 117.6 in -800ft DA. I now run a little heavier for consistency and she'dl usually go 11.8s in 1000ft DAs, that is until i had the converter loosened...big mistake. Need to have that undone over the winter.
The converter was their std 2800 stall unit. And it probably flashed to 2900-3000. It was plenty tight on the street, so i figured i'd have it loosened a bit since my torque peak should be around 4000 rpms. I didn't want to lose any mph and they assured me they could loosen it about 200-300 without hurting the efficiency. WRONG!!!!
It doesn't feel any looser to me and the car 60s about the same, but it's hurt after that. I estimate i lost almost a tenth and 2-3 mph in the 1/4 with all increments suffering after the 60 foot mark. I assume it's the converter since its the only thing i've changed since last year. I've gone over everything else i can think of. Going to have Protorque undo the change after the season.
Maybe i'm trying to squeeze too much outa this setup. For the last 3 years, everything i've tried hurt me considerably and i had to undo it.
