With 71-73, Chawrasia was lying tied-15th, but many golfers were still on the course.
One of the golfers yet to finish was India's other star Shiv Kapur, who shot 73 in the first round but was two-under through five holes in the second.
At two-under, he was also tied-15th but with 13 more holes to play.
Chawrasia, winner of four European Tour titles in his career, added an even par 73 to his first round 71.
Graeme Storm produced a big finish to take a share of the clubhouse lead on day two. The Englishman only kept his card last season after Patrick Reed failed to play the required number of events but he has grasped his second chance with both hands, winning the BMW SA Open hosted by City of Ekurhuleni and finishing in the top ten at last week's BMW PGA Championship.
