I hear ya!
Based on the specs on that rig, supercharged, I would have to resort to some sort of boost in pressure too in order to keep up, and then the question would be "for how long".
it's funny with cars and boats, regarding ability to maintain speed. One day I was coming onto the interstate with a V8 Porsche 928 5-speed, which is engineered to dominate the Autobahn, and did. It is geared to run at 100 with no strain, and I have done it on many occasions. As I entered the interstate I came along side a hopped up Corvette with sidepipes and I could tell it was geared for the drag strip, and I was geared for the Autobahn. He took off, reached an impressive speed, but man I could tell he was out of RPM......all the while I was back there with the AC on just purring at a ridiculous low RPM. I had a LOT of gear and RPM left, and I thought to myself, "I wonder how long this guy is going to be able to maintain this speed". Pretty soon, a puff of smoke, and he let off the throttles, he had all he wanted and I just continues on by to my destination.
Same with boats.........out on the water what I want to do with the 427 Lancer is to be able to make a good speed, but also be able to maintain it. I know the hull will take it so that is going to be some fun in rough water when anyone tries to keep up, I'll just increase speed to see how much pounding they can stand, as there are some boats with a capable deep v hull like this around but most are not. Then with the prop, gear, and massive torque of the big dog, I will set things up not necessarily for ultimate top speed, but for maintaining a rapid clip with low engine stress.
Of course when it comes time to race Herr Namken, I will be running on a quarter tank of racing fuel, all upholstery and beer coolers will be jettisoned, I'll have a racing prop affixed, I will have polished the bottom of the hull with a Q-tip, and I will have opened a can of whoop-ass, ha!
