Dual quads versus big hammer!!!...

I think if you had Jpars car on a chassis dyno, and did some pulls starting at a pretty low rpm(2000-ish), the doors would hardly open at all, then as the rpm went up...... they’d open more and more(which is how it’s supposed to work).
The question would be.......how loose can the door spring be(how soon/far can the doors open) without negatively impacting the power.
There is a reason the doors are there.
