Mercury has a density of 13.5 (hydraulic oil about 0.88), which within a 2.5 meter long line from rear to front would create a pressure of 13.5 Bar under 4g deceleration. If this pressure would affect an 80 mm diameter hydraulic cylinder it would create 6800 N (680 kg) of force, probably enough to lift the suspension on each front wheel to raise the nose.
So that's what it was all about, clever, no wonder they wanted to spend time on it, such a shame if it was banned?
After this xcitement, I did a recalc of my initial draft above, with 3.2 meter wheelbase, 5g deceleration and 13.5 density,
a 22 Bar pressure would be generated at the front, which in a 65 mm heave-cylinder should create 7200 N on each side, surely enough to lift the nose 5-10 mm. Brilliant, but is it legal?
As for the amount of mercury, an 8 mm ID line from front to rear would hold no more than 160 cc, or 2.2 kg.
