Intimidator 305 image

In the first of a series of articles in which we'll ask readers to share their opinions on current theme park topics, this week we're asking for your views on Kings Dominion's decision to add trim brakes to its Intimidator 305 rollercoaster.

The high speed and intense twists and turns of Intimidator 305 are designed to mimic the experience of NASCAR driving, with the coaster's name being a tribute to 7-time NASCAR champion Dale Earnhardt. The $25 million Intamin Giga Coaster opened to rave reviews from coaster enthusiasts on April 3, 2010. However, one particularly tight turn has led to many riders experiencing "blackouts" due to the high g-forces exerted on them.

In response, Kings Dominion installed the brakes on the coaster's 300-feet first drop, reducing its top speed from 92mph to around 79.5mph. Despite this update (and the addition of new shoulder harnesses to the ride's trains), reports of blackouts have continued to flood in. In fact, much to our surprise, Theme Park Tourist's original article on the addition of the trim brakes has become one of the most popular stories we've ever published.

You can see a great point-of-view video of Intimidator 305 below, courtesy of Theme Park Review:

What exactly causes the blackout phenomenon, which occurs during Intimidator 305's sharp first bend (immediately after the first drop)? Essentially, when the coaster pulls out of the drop and rockets around the corner at high speed, positive g-forces are exerted on the rider's body. This effect - which is the opposite of "weightlessness" - causes blood to rush to the lower extremeties of the body, starving the brain of oxygen. This can cause both blackouts, where a person loses vision completely whilst retaining consciousness, or less severe greyouts in which vision is retained but with a perceived dimming of colors. See CoasterForce's excellent g-forces guide for further information.

It's clear from the comments on TPT's news stories that some riders love the blackout sensation, while others hate it. Kings Dominion is still experimenting with the location and level of braking on Intimidator 305, so we thought this was a great time to revisit the debate and get your views. First, let's recap the arguments made to date on whether the park was right to add trim brakes to the ride.

The "Yes" argument

Predictably, the arguments for altering Intimidator 305 center around the need to eliminate the blackout sensation. One rider, Amy, claims to have lost her contact lenses during the ride and comments: "It is ridiculous to build a ride that will cause someone to pass out. I suggest to people to keep their eyes closed if they wear contacts and not to ride if you don't want to pass out!"

The subject is being actively discussed at the park, with BigDragon claiming: "Most people were commenting on the sensation. Some liked it, but others like me really don't like the feeling...I found I was actively fighting against the ride instead of enjoying it...It's cool to suck it up and not let the ride beat you, but everyone in my group pretty much agreed never to ride it again once they got over themselves. We were far from alone."

With some suggesting that the blackout reports and negative word-of-mouth are already affecting the ride's popularity, many are understanding of King Dominion's desire to mitigate the effects. Coaster Fan backs the addition of the brakes, saying: "For the average rider, I am sure this sensation is too much hence the lack of ridership. But the park would not spend the money to build an amazing ride and then have no one want to ride it. I support their decision to modify it and appeal to the largest demographic of guests."

Joel Bullock, reviewing Intimidator 305 on his popular Coaster Critic blog, also backs Kings Dominion's move. He says: "If you feel that the ride was better before, then please hold those rides dear, but you’re wasting your time by complaining. They have to build these mega attractions so that they suit the general public, not just the thrill junkies out there. For 99.99% of people, blacking out on a roller coaster is not a desired state. No matter if the airtime is better. And, for the record, I barely noticed the trims."

The "No" argument

Intimidator 305 was open for several weeks prior to the installation of trim brakes, and some of those who experienced the ride in its "untrimmed" state are not happy about the change. Among them is Chris B: "I took a ride before the trim brakes were added and I am now very disappointed with the ride. Not in whole, but compared to what it was and what it is now. Now it's just another ride. It WAS the best. The 1st time I rode it I did have a brief grey out. This is what 'intimidated' me about riding it again."

Others agree that the brakes have taken the edge off Intimidator 305, with TwinTurbo300zx complaining: "The drop feels really slow. Once you get to the top and start to go down, about half-way through you can feel the brakes slowing down the cart. It actually felt like we slowed down so much that the carts behind us were going to flip over our heads (we were in the front), kind of like if you used only the front brake on a motorcycle."

Many are unsympathetic to the view that Kings Dominion needs Intimidator 305 to appeal to a wide audience, pointing out (often in the strongest terms) that the park has tamer rides on offer for those who want them. Winner offers one of the less offensive opinions: "If they continue to slow it down, it may as well only be half as tall. The speed is the main attraction to this ride. The signs clearly say that if you're not in the right state of mind or being, to not ride. Sorry that some people didn't enjoy it, but not every ride is meant to be enjoyed by every patron to the park."

The "maybe" argument

While most commenters to date are in one camp or the other, Alien does offer a more balanced view - and a suggestion for an alternative approach: "While I thought it was an amazing ride, I did think it was a little too intense...I would suggest removing the trims to keep the speed, re-profiling the turn so that it is an overbanked hill / turn, much like that on Millenium Force (at Cedar Point). I believe that would cut the sustained g's & keep the pace up. Further along the ride I would also re-profile the viscious direction changes to make them smoother, longer and frankly less likely to damage peoples necks. Make the coaster once again what it is supposed to be, a gravity driven powerhouse of fun."

Our take

It's difficult for us to comment on the Intimidator 305 changes, given that we've not yet been able to experience the ride - so please take our views with a pinch of salt. However, we can sympathize with Kings Dominion wanting to ensure that its huge investment pays off. Quite simply, a ride that only appeals to extreme coaster junkies is not going to achieve the park's aim of attracting new and returning guests.

Having said that, while the addition of trim brakes was probably inevitable given the publicity around the blackouts, we hope it is only temporary. Kings Dominion will have an opportunity to make significant updates to the ride during the off-season, and we'd like to see the first turn (and others, if necessary) re-profiled to reduce the g-forces to manageable levels whilst retaining the ride's high speed. A ride which tames its velocity is hardly a fitting tribute to a NASCAR racing legend, after all.

People have totally overreacted to the blackouts. It happens on loads of other coasters without anything like this level of hype...it's not like you actually go unconscious or anything. Remove the trims and let people experience the ride as it was supposed to be!

I rode it 22 times before trims and it was truly the greatest coaster ever. I still blackout just now the ride is slower. Its still a great ride but I live near the park and have seen that the trims did nothing to increase "ridership"

Not tried it without the trims but it's still a great ride. It's about more than the first drop...the rest of the ride is awesome.

Surprised they didn't pick up on the blackouts during testing. Must have decided it wasn't a big deal?

Thanks for the comments, guys.

Looks like 2-0 to the "no" argument at the moment!

$25 million on a giga coaster from Intamin really should buy 3+ hour waits, worldwide recognition, and stories of happy ride experiences. Outside of the initial rush you'd struggle to find a 10 minute wait for Intimidator 305, and people talk more about the blackouts and changes to the ride as opposed to what they liked best about it. KD has to do something to enhance opinion about the ride and to get the general public more interested in riding. They really have no choice. KD has to make modifications or Intimidator 305 will meet the same fate as Drachen Fire.

I can say that I loved riding Millenium Force early one weekend morning after a 2 hour wait. I was in the front row, got plastered with gnats during the ride, loved the overbanked turns, and enjoyed the speed. A conversation about Intimidator 305 would immediately bring up the terrible blackout sensation from that first turn and the annoying high-speed "twisties" I had to be ready for so as to not bang my head into to over-the-shoulder restraints (apparently they're gone now). I enjoyed Millenium Force but had to fight against Intimidator 305 even after the trims were installed. One coaster (MF) left me with a smile as I wiped gnats off my shirt and anticipated riding it again in the future while the other coaster (I305) left me with a headache and zero desire to ever ride it again.

I really think Intimidator 305 needs to meet the same fate as Drachen Fire. It's in way too compact a plot, it's in an awkward out-of-the-way location, and I don't think simply widening that first turn is going to help. I'm sorry I don't agree with the thrill seekers out there as I'm just a "general public" regular person that travels in packs filled with friends and family. When Hershey Park built Storm Runner I was happy to get a season pass and make multiple trips with all sorts of friends and family. For Kings Dominion I refuse to even ride Intimidator 305 again so there's no chance of me coming back for a few years. Seat belts and trim brakes aren't enough.
