How did you turn the blower on and off George, with an a/c compressor clutch?
Doug,
I didn't turn it on or off, the movie guys did. and, like everything else in the movies, the blower was a facade.
No air can pass through a roots blower that isn't turning. So that had to be an empty case, with a carb hidden somewhere inside.
The gilmer belt may have been attached to the crank via an a/c clutch, OR there may have been an electric motor below the hood to turn the belt.
I've read one mention of a $20K functional blower assembly on that car, but I seriously doubt it. There would have to have been a separate naturally aspirated intake assembly, and the blower assembly, and a way to switch between them. There is a company churning out Mad Max replicas, and their blowers are hollow.

"BLOWER ASSEMBLY: This is all custom made, with exception of the blower casing. The Scott hat, Weiand front cover, and pulleys are all custom made. Kit also comes with an electric motor and an adapter kit for non-A/C 302/351 Cleveland engines. $4000 AUD"
thought you had me on that one , eh? lol......

did you know that gibson was born in ny and abducted, ah, migrated, um, emigrated to ausieland at a very young age?
incidentally, have you seen the short waterpump for the sb? clevelands next, no more hump, 1=1/2 in shorter
that short idf manifold you saw has to be the only one on the face of this planet, should have bought it

Actually,I had a 302 in a Mustang with a roots blower.I lost a belt and was forced to drive back to the hotel I was staying at .The air passing through the carb rotated the lobes very slowly .The car ran fine ( WAY down on power.)
The pulley turned very slowly.

Notice the rotors of your blower did have to turn in order to pass air. It is interesting that they could free spin with the belt removed, come to think of it I've heard of someone doing that before.
In the case of the Mad Max motor, the blower was hooked to a belt & not allowed to free spin, and in several scenes it was obvious that the blower was not turning.

Come on! This was in the future, they had the technology! 
The future never gets here.
Actually the car is in a musuem in Adelaide Australia!
The car started life as a standard 1973 XB GT Ford Falcon Coupe, a car exclusive to Australia. And for the first few years of its life, this is pretty much how it stayed.
Then in 1976, film makers Byron Kennedy and George Miller began pre-production on Mad Max. They needed a vehicle to feature in the film as the black police 'Interceptor' - a high performance, evil looking Australian car.Following the production of Mad Max, the car was no longer needed, and was modified once more to make it suitable for use as a standard road car (basically by removing the blower and the side pipes). It was then toured around Melbourne to shopping centres, car shows and so on as part of the promotion done for the film.

My dad was in Adelaid. He said they had the best bar fights.
If you want to see another famous aussie car, then you have to watch "running on empty"or as you called it "fast lane fever"
it's an Aussie cult film.
The main car in the film is a Ford GTHO Phase 3.
It was one of the fastest production cars of it's time , and yes it's running an aussie 351 cleveland.

The 1971 Falcon XY, GT-HO phase III, had an "R code" motor, the same motor as the 1971 351 Boss Mustang. The US Boss 351 used an Autolite 4300D carb, the Aussie GT-HO phase III had a 780 cfm Holley. Folks rate the power of the GT-HO phase III motor between 370 and 390 bhp.
The GT-HO phase IIIs distinction is that it had the highest top speed of any 4 door sedan in the world in 1971! That was with the stock 3.25:1 gearing.
performance with that gearing was:
0 to 60 mph (100 kph): 6.5 seconds
standing 1/4 mile: 14.4 seconds
top speed: 142 mph
Not bad for a 4 door sedan, heh? They cleaned house at Bathurst that year.
Only 300 were made. They are worth a bunch of money now! Perhaps your country's most famous muscle car.
Over here in the states, the 1971 Boss 351 Mustang had the fastest acceleration times of any showroom Mustang ever, and it held that title for over 20 years, until the 32 valve Cobra Mustang came along in the 1990s. It accelerated even faster than the big block Mustangs, not because it had more power, but because it overwhelmed the stock chassis less. In other words, it spun the tires less.
