Doug Siddens and his RZR during a Pikes Peak practice session – Click above to watch the video after the jump

We all love talking about the Unlimited Class vehicles that take on the Pikes Peak International Hill Climb (for good reason, of course). There are plenty of other classes though, and some of the drivers helming these vehicles are clearly insane.

Take Doug Siddens, for example. Siddens is running a customized Polaris RZR, which has been tuned by MCX-USA and now produces around 300 horsepower. The original motor has been swapped out in favor of an Apex 998-cc turbocharged engine that was taken from a Yamaha snowmobile. Siddens runs the vehicle in the Exhibition Powersport class, which was just launched in 2010. That year, his RZR had less power, yet still ran up the hill in 14:03.

Click past the jump to ride along with Siddens as he runs up Pikes Peak during a practice session for this year's upcoming race. Controlling his RZR is clearly a full-time job, and Siddens is working overtime. Also, be sure to check out photos of his vehicle in the gallery below, and check out RZRForums.net for information on the build process.

      Haha don't worry guys, I'll have it dialed in on race day! This was the first time the RZR-X had ran since the 2010 PPIHC and we about tripled the horsepower! Needless to say, we didn't quite know what to expect. Taller and wider tires are on the way :)

        Yeah, I can see how triple the horsepower can really catch you by surprise! Huge pat on the back for your efforts, to be the first to start the class and continue to improve from one year to the next is certainly an accomplishment! Hopefully the class will take off and there will be a little more competition for you to walk away from. ;)
