Psyclone, Wooden roller coaster in Valencia, California.

Psyclone was a wooden roller coaster at Six Flags Magic Mountain in Santa Clarita, California, built of unpainted Southern Yellow pine by the Dinn Corporation from a Curtis D. Summers design. Its layout had eleven hills, five high-speed banked turns and a 183-foot (56 m) dark tunnel, and it ran two six-car trains made by Bolliger & Mabillard.

Announced on December 27, 1990, Psyclone was built on the former site of Shockwave at the back of Six Flags Magic Mountain. Curtis D. Summers designed it and Dinn Corporation constructed it of unpainted Southern Yellow pine, following their Georgia Cyclone; Six Flags asked for a gentler profile. It opened March 23, 1991, was damaged in the 1994 Northridge earthquake, and was demolished in 2007.

The design mirrored the layout of New York's Coney Island Cyclone, reflecting a connection between East and West Coast amusement attractions.

Psyclone stood at the back of Six Flags Magic Mountain, on the site previously occupied by Shockwave. Its layout ran through eleven hills, five banked high-speed turns and a 56-metre dark tunnel. After the 1994 Northridge earthquake, trim brakes were added that slowed the trains to a crawl through each turn.

Psyclone's two trains each had six cars seating four riders, and each train weighed about 2.3 tonnes. They were the only wooden coaster trains Bolliger & Mabillard ever built, a firm otherwise known for steel coasters.
