Spin depends on the number of revolutions imparted on the ball. To get maximum spin,two things are important.
Firstly to use your whole body to spin the bowl.Warnie was a stocky fellow. He really gave it a rip.
Secondly, the process of above,i.e the technique.
1) run up-first step of bowling. This is important to build momentum upto the delivery stride.when he started his career, he would jog couple of spaces. Later he would just walk. Didn't make a difference to him, because of his physical structure.
2) delivery stride-back foot parallel to the crease, front toe facing fine leg. Front shoulder, hips towards the batsman, knee lifted, high front arm. This gives the perfect side on position, also called coilling.
3) release-using his front arm for direction, imparts enormous side spin on the ball with wrist corked. His arm speed was as quick as that of say, Gillespie.The catch here is that revolutions have to be more than the arm speed, else the bowl would just skid.
4) After the release-He would pivot around his front leg and follow through. His pivot was bull strong, that would result in oomph. Now his right shoulder would be facing the batsman and bowling arm well past his body.This is uncoiling. Finally bending forward would complete his action. Now he has given his all to spin the ball.
Additionally there is a concept, Magnus effect .It says that the direction in which the revolutions are imparted, ball behaves exactly reverse in the air.
So, Warne would get the drift into the right hander,because of side spin.This would seemingly increase the turn after the ball pitches,because batsman would play inside the line of the ball.
The ball of the century, dismissal of Getting, is a classic example.
