Ultra Twister was a steel roller coaster at Six Flags AstroWorld in Houston, Texas. Built by the Japanese company Togo, it was a pipeline coaster whose three inversions were all heartline rolls. It ran at AstroWorld from 1990 until the park closed permanently on October 30, 2005.

RCDB lists the ride at 96.8 feet tall with a 92-foot drop, a top speed of 44 mph, 1,421 feet of track and a ride time of 1 minute 40 seconds. Each car seated six riders, two across in three rows, and the course included a switch track.

History

Ultra Twister first opened at Six Flags Great Adventure in Jackson, New Jersey, on June 6, 1986, as the first heartline roll coaster in the United States. Recurring stress fractures in the track caused frequent downtime there, and the ride was taken down in 1989 and sent to AstroWorld. It reopened in Houston in 1990 with its vertical lift hill changed to an angle of about 45 degrees, and it was repainted blue and green for the 2004 season.

After AstroWorld closed, the coaster was dismantled and moved to Six Flags America in Maryland, where it was kept in storage until it was removed in 2010.
