The trip there. Lake Havasu City was the most interesting place I stopped. I'm all over all things technological and powerful. I stumbled on the "Nautical Beachfront Resort" which was a posh place for people to play with expensive toys in the sun.
First a bit about LHC - there are no boat speed limits and no exhaust noise restrictions. So it is like a dragstrip on the water. In Colorado all lakes have a speed limit of 40 and having a loud boat will get you in trouble right away. I have a boat that will do 75 MPH here. When we take it out the rangers will usually say something like "How fast will that boat go?" My wife has strict training to say "40" to which the rangers say something like "Good, keep it under that." Then we go do whatever we want ( - :
I ran into this machine in a parking lot. 20' tunnel hull with a pointed prow (not a picklefork). The owner was there to talk to and I drilled him. He built that motor after getting the boat. Fully dynamometer tested to a bit over 1,000 HP. The most interesting thing to see in this picture is the ~2" layer below the roots blower with "The Blower Shop" on it. That is a seawater-cooled intercooler. The pickup is on the pumper plate and is passive, just rams water through the system. Dyno tests showed this added 160 HP to the mix, impressive.
He said the boat cruises nicely at 3,500 RPM doing 55 MPH. No boost at that speed, just move right along. Boost is limited to 6 PSI. That day he did 106 MPH on the lake at 6,700 RPM. The boat is capable of 115 MPH and he is working to get it there.
