Intimidator 305, sometimes abbreviated I-305, is an Intamin giga roller coaster located at Kings Dominion in Doswell, Virginia, USA. Opened in April 2010, it is the third non-launched roller coaster over 300 feet tall, following Millennium Force at Cedar Point and Steel Dragon 2000 at Nagashima Spa Land.
On August 20, 2009, Intimidator 305 was announced. Kings Dominion broke ground on Intimidator 305 two months prior to the announcement on June 1, 2009. The first pieces of track arrived a few days later. On August 19, the first pieces of steel were put into place. The lift hill was topped off in November 2009. Construction crews continued to construct the ride throughout the winter and the last piece of track was lifted into place on January 9, 2010. Intimidator 305's first test run was on Sunday, March 14, 2010.
Intimidator 305 opened to guests on April 2, 2010.
Some riders experienced problems immediately on the turn following the first drop due to overwhelming g-forces produced in the turn's original design. Riders reported symptoms of greying or blacking out, which is a brief loss of vision, or even consciousness, depending on severity. Riders experienced over 5 highly sustained G's on the turn. To lower the number of occurrences, Kings Dominion reduced the coaster's maximum speed by temporarily installing trim brakes on the first drop.
In July 2010, new over-the-shoulder-restraints with a strapped, padded design were added to keep riders more secured in their seats. This was because riders disliked Intamin's hard over-the-shoulder-restraints, along with head-banging and floating higher than what was comfortable.
During the 2010-2011 off-season, the coaster's first turn was redesigned, resulting in a wider turn radius and fewer g-forces. The major modification allowed them to remove the trim brakes on the first drop, returning the ride to its original maximum speed of 90 mph.
The lift hill structure for Intimidator 305 is unique in that the lift hill and crest only have three points of support. The balance of the ride's track consists of Intamin's new double-spine track, which allows for longer spans with fewer supports, particularly on crest curves.
While the train is being loaded in the station, the catch car of the cable lift is latched onto the middle car of the train. Before the train leaves the station, a recording that states, "Gentlemen, start your engines!" is heard followed by a loud revving sound. Once the train is dispatched, the train ascends the 305 foot tall cable lift hill at a 45-degree angle. Once the train crests the top of the lift hill, the train descends down the 300 foot, 85-degree drop, reaching speeds up to 90 mph. The train turns right into the famous 270-degree "black-out" turn, where riders sustain high amounts of positive G's, before ascending a 150 foot tall airtime hill. The train then descends into a high-speed bunny hop before entering another high-speed turn. The train then maneuvers 3 sharp twists before entering the final high-speed turn. The train then climbs another hill with trim brakes, followed by another airtime hill before entering a final twist and then climbing a small, twisty bunny hop into the magnetic brakes. One cycle of the ride lasts about 3 minutes.
2 trains with 8 cars per train. Riders are arranged 2 across in 2 rows for a total of 32 riders per train.
