The rotational upward lift of the ladderbar front eye, will be equally downward on the wheeliebar, how much, will depend on the bar length difference/multiplication and the squat characteristics needed to launch the car, which is depending on the car and track surface.

We've ran the wheelie bar more than 6inches up in the air on our car to try to make the bars barely touch the track at the hit.
We do not use the wheelie bar to increase wheel speed. We basically run no-prep, just inconsistent.
They are probably longer than most.

Here's a picture that shows how high it can get.
