Carpenter, an Indianapolis native who has only two career wins, had qualified no better than eighth in his previous nine races at the renowned speedway, which will host this year's May 26 event.
He emerged with the pole -- only the second of his career -- after the "Fast Nine" shootout had been delayed more than 2 hours by rain.
Qualifying second was rookie Carlos Munoz at 228.342 mph while Andretti teammate Marco Andretti claimed the outside position of the front row after registering a lap average of 228.261 mph.
