 On May 28 , 2003 , a trademark for the name " Silver Bullet " was filed by Cedar Fair , the owners of the park . Construction for the new roller coaster began in September 2003 with the relocation of The Church of Reflections . As part of a $ 85 million investment in all Cedar Fair parks , Silver Bullet was announced to the public on December 1 , 2003 . The final piece of track was placed on September 30 , 2004 . On November 5 , 2004 , Knott 's Berry Farm launched a " First Rider Auction " in which people from anywhere in the world would bid against each other in order to be one of the first public riders on Silver Bullet on December 7 , 2004 . Although sixty seats were made available , only 13 of these received bids . Out of those bids , the highest bid was $ 200 ( US ) , and a total of $ 1643 was raised with all the money going to the Speech & Language Development Center of Buena Park . After construction and testing was completed , the roller coaster opened first to the media , then to the public on December 7 , 2004 though the initial scheduled opening was on Christmas Eve of 2004 . Silver Bullet was also one of four attractions that opened at Knott 's Berry Farm in the same year and carries a western theme .

 Silver Bullet 's layout passes through three of the park 's themed areas : Ghost Town , Fiesta Village , and Indian Trails . 
 After the train departs from the station , it makes a 90 degree right turn before beginning to climb the 146 @-@ foot ( 45 m ) lift hill . Once at the top , the train goes through a pre @-@ drop before entering the 109 @-@ foot ( 33 m ) downward right drop . Once at the bottom , the train enters a 105 @-@ foot ( 32 m ) loop . After exiting the loop , the train makes a banked right turn leading into the cobra roll . Almost immediately after , the train goes through a zero @-@ gravity roll followed by a downward left helix . Then , the train enters the first of two corkscrews which are separated by a banked left turn . Next , the train enters an upward left helix ( the beginning of the helix is close to water ) before entering the brake run . The train then makes a right turn into a second , shorter , brake run which leads straight back to the station . One cycle lasts approximately two minutes and thirty seconds .
