454MPI should live a fairly reasonable life at 3 psi with a Procharger and 4600 ish.
And he never said his motors were modded, he just said they had been reworked. Maybe a rework with stock parts, maybe some hop up goodies, but any way you look at it, a 3 psi charger and revs under 4800 should run well enough in that setup.
As far as throwing out bodies, the fastest I've ever voluntarily leaped out of a boat is mid to high 50's. I don't know that I want to go out above 65 ish. We convinced one friend how fun it was to leap out of a boat at speed and when he jumped out at around 40, he blew his eardrum completely out. Never did heal right. And he blamed us for his ignorance on how to properly jump out... some people.
And as far as bodies hitting the side of the boat. They do slow you down. Especially when they hang on to a cleat for a few hundred yards. That really screws up your data. And the ones that drag the farthest seem to be the most angry cause it hurts and they bruise and all - like it is somehow YOUR fault that they were stupid enough to hang on in the first place. Duh..
But back to the thread, I definitely feel that undesirable women and/or barflys would be the best choice. Even if they file a formal complaint, nobody will believe the barflys and nobody will care about the undesirable women. They get a little attention, you get your test data. It's a win-win.
My Formula picks up a solid 2 mph between full and qtr tank. There may be another 1/2 to 1 if you actually want to run it dry. That sucks, though, cause you have to get your tow rope all wet when they drag you to the gas dock. Then you gotta give them some gas or beer or something. That last mph isn't worth the hassle..
