Hottest PSD??
A while back, shortly after I joined I jumped in and kinda hijacked a thread a little asking questions about Ben Miller's "Double Overtime" SuperDuty pulling truck with highly modified PSD power. Now.. thanks to another site that I follow I have found some pics and info about this truck.
Here is a few pictures. http://sports.webshots.com/photo/250...63062029NgNatn And here is a video of the truck in action... there is also footage of some other trucks on the video http://video.thedieselgarage.com/vid...2a0085f023.htm There is nothing left of this engine from stock except for the block. It has been in process for over 4 years, and reportedly cost over $150,000 to build. I have personally spoken to the engine builder about this engine, and the horsepower and torque it produces is unreal. I don't remember the exact numbers and I don't want to post any guesses. Pulling season is over now... but with this new information, and having seen the pics and video, I can't wait for next summer so I can see this one on the track in person.

The video is pretty large.. and since I am on dial up it is taking a while for me to see it all... but I just wanted to add a little information about it. The very first SuperDuty in the video is the "Double Overtime" truck with the "SuperStroke" engine. There is another SuperDuty truck later in the video but it is not PSD powered, it has a Cummins.

One of the exhaust stacks is shorter, and much smaller in diameter because it is connected to the wastegate. The waste gate on that engine is very cool... it is boost activated and adjustable (between runs not on the fly).

To the best of my understanding, it is a valve that open when you are making boost from the turbo. It is kind of like a safty valve, so you don't build tooo much pressure and start tearing stuff up. The more boost, the more it opens to let off the pressure that is made.

The 6.0's can regulate the boost by utilizing the variable veins I think
