What is everyone launching their car at?

4100-4300 on 29.5 x 10.5 PBR's with 5700-5900 flash stall.

We try to keep our launch rpm on the lower side for full tree/bracket racing a SBC. Our old NA set-up mostly used a 2,800 launch rpm & that was with a 5,900 rpm convertor. The car ran 6.20s/9.90s.

We primarily use launch rpm to adjust reaction times.
