Stupid drag racing question, but I'm not proud .....
The scientific explanation is down to Mr Newton -
"For every action there is an equal and opposite reaction"
.....and Goody - although our water does twist the other way down the plug hole, our Mopars still lift the front left - :bootysha:
and just so 70 Duster gets the full story -
As the motor spins the crank in a clockwise direction - the pinion wants to "climb" the crown wheel (this is the "opposite reaction" bit)
Of course the pinion cant move, so three things happen:
1. - The right side of the axle starts to twist UPWARDS into the wheel well (This is why the right wheel in a single spinner is the one that skids)
2. - The frame twists full length in the opposite direction to the engine rotation - as the housing resists the "twisting" energy -
3 - it also causes the axle housing to "rotate" across its length - so we use a snubber and caltracks or whatever to stop it twisting and trying to lift both back wheels off the tarmac. This is why Chebbies "squat"
So going back to 1 and 2 - Mr Newton comes to the party again, and as the right wheel raises, the rear right qtr of the car drops, the chassis twists even more and the left front comes up.
Now IF the rear end is tied down with a snubber and clamps, the "torsion" created by the pinion wanting to climb up the crown wheel is transferred back up the frame and the left front corner twists anyhow.
Of course this is why we stick the battery on the RIGHT side in the trunk - with the car wanting to pick up its right wheel, the more weight on that side keeps the wheel pinned down to the asphalt.
(A lot of folks see the left rear side go higher, and think thats the side that needs traction - In reality, the left side is reacting to the right rear wheel trying to "pick up" - like a "see saw" or fulcrum)
Now onto # 3 -
Newton also effects whats happening with the diff housing as well - Not only does the pinion rotation cause the right wheel to lift, but the twist of the housing is like a horse "pig rooting", its trying to lift both wheels off the road, so we limit the pinion rotation.
At least thats the way we "Aussies" understand it anyhow, :D
