Using two superchargers gives more power with less boost. Used in tandom, they displace huge amounts of air, and you don't need to spin them nearly as fast. Quite advantageous. Less parasitic loss. Less heat. Not to mention the use of just 91 octane fuel. The list goes on and on.

No problem. Whipple's are screw compressors and are not as hard to turn as a roots blower. use a serpentine belt in Marine applications. No relief valve allowed under a covered engine hatch. So the belt slips if there is a blower sneeze

The difference would be that if the engine drops a rod or something similar the bits of metal go mostly sideways. If you're in front of it in the boat you get a fright and complain about the dead engine and the holes in the boat. If you're standing next to it you complain about the holes in you. If you can still complain, that is.

no lol. at the time they werent making the twin screws large enough, now they do, see psi blowers. the top top fuel teams run 1 x PSI brand twin screw blower.

Less parasitic loss because the superchargers don't have to operate at such a high RPM. The faster you spin them, the more power they will consume. Any blower will be more efficient when it doesn't have to operate at its maximum output. Heat is created not so much by spinning so fast, but by the air being compressed on the outlet, or underside of the supercharger. That said, you would really have to spin and load the hell out of this setup, before it became not so efficient.

they use two twin screw superchargers because most twin screw superchargers dont displace enough air to feed big cubic inch engines.

Cause there was steam or something else everywhere, and something could've happened to the motor while on the dyno, and he was standing in the chamber

Steam is because it is a boat engine and the headers have water going through them. The dyno did not have a boost gage so boost had to be read by standing there and looking at it. And ... what's the difference between standing near the engine or sitting right in front of it in a boat?

Any problems with belt slippage? Why not go to a cog type belt?

An idiot why? Only 5 lbs of boost because no more was needed. The boat goes 120+ with a mild tune.
