Duramax boat engines????

The diesel will run at a higher % of full load longer (not total hours but hours at WOT) and harder than a gas engine can. back when offshore racing was "ocean" racing and Open/Class 1races were 150-185 miles long. The gas boats would run easy when the race started, they were heavy with fuel and knew that 50%+ would break and not finish, it was a game of endurance. As the boats burned fuel they could run faster and harder (more % of throttle)
Then here come Buzzi (who was not the first diesel guy by any means but read the rules a little better), his plan was when the flag drops push the throttles all the way forward and get out front. The gas boats are faster but they will not run so fast as to break early on. Make the gas boats chase me so they stay within striking range to pass us. They will have to run faster & harder than planned and will most likely break before catching us. If they are burning too much fuel they will slow down and at the end be too far back to catch up anyway.
Watch the old races, you'll see I'm right!

My truck / turbo's were built for max torque. I am not a big fan of the high hp low torque build, i think high timing, high rpm, hopefully balanced...
Thanks i actually traded it in 3 years ago, after i parted it out.
Check this out...The setup is really bad for the track but still cool.

PPE did a couple boats with the duramax and Imco, but it was not that big of a hit, really hard to get on plane at a low RPM with out running a trany, and that take to much room. http://www.youtube.com/watch?v=dR3laaqKAjQ http://www.youtube.com/watch?v=Y4ugzTL2y1U
