Maximum normal g is +1.75. You can do an impressive display at 1.25 to 1.5. I don't think we did a display in excess of 1.5g. High bank turns at 1.5g and around 190k are impressive enough.
A run in and climb is done at low speed not high speed. At high speed the climb would not be established in front of the crowd. At 200k or so the rotation and climb are in frint of the crowd.
Usual disclaimers, it was a long time ago.
