performance figures

[Foxtrot X-Ray]

I've come up with two general outlines of how the system may work as shown in the films. The first is a bit more complex, and would require the incorporation of two seperate Air Flow meters (EFI) or possibly carburetors..





My concern with this setup is boost pressure leakage through the switch gate (Sorry, forgot to mark that in the original drawing.. It's the Red Bit) and out the "B" intake.

















The other is much more simple.














However, I have concerns on this one.. Would an engine have enough Vacuum to pull air through the blower housing?


The rotors would have to Pinwheel inside the housing and the Blowers I've personally handled didn't seem that easy to turn..





I think this setup would be easier to operate carbureted (in a blow-through configuration, IE Carburetor in an enclosed, air tight box under the Blower)

jesus i hope this works for my sake .i dare say it will be engaged by the red knob on the gear stick.

1st problem is there's no electrromagnetic clutch powerful enough to turn a 6-71and produce a significant amount of boost. If there were it would put a huge demand on the battery and charging system.


An engine can produce enough vacuum to make the rotors move at higher rpm (way above idle) but they won't freewheel because there's too much resistance. The engine would basically be suffocating all the time.

so it looks like its never gona happen then,its a crying shame.i bet everyone of us dies for the moment when you can go into "vapourize rear tyres mode at the pull of of a red knob" IF YOU WANA GO YA GOTTA BLOW !!

Well, that kills the setup in figure 2..


(I did see a supercharged car lose it's belt on cruise night once.. He drove it half a mile up the street to a well lit area to replace.


But I don't think it ran WELL on that half mile)





Setup Number 1 might still work, but it would require a different "clutch" mechanism than would fit in the pullys.





That said, I'd like to quote Jerry Dyers regarding the idea of an on/off system for a supercharger..





"You already have an off switch for your Supercharger. It's called your FOOT"





Meaning that the throttle controls the amount of air (which controlls the fuel) going into your engine..


If you don't have your foot mashed on the gas pedal.. It's not gonna use much fuel.





Now, Myself.. If I Had the money to build my own Interceptor replica, I'd actually feel compelled to go a bit different than what we see on the screen..





First difference would be the engine.. she'd be a real supercharged 351 cleveland with a nitrous oxide injection system (Controlled by a little red switch on the shifter)


That's IF I didn't choose to heat up an '05 Mustang Modular V-8


Also, I'd go with a five speed transmission & stainless exhaust tubing & headers.





Also on list of changes would be the wheel/tyre combo.. I'd go with 16"x10" & 16"x7" rims & matching tires.

There doesn't need to be an electromagnetic clutch powerful enough to clutch a 6-71. As shown in the above Super Stallion article, there are a few companies(including Ford) that have made Hydro-Electric clutches. You energize a fluid and it becomes as solid as a rock.

"Well, that kills the setup in figure 2."


Or figure out a way for air to by-pass the rotors. One problem for retaining the look of the Scott set-up is there's very little space for any air filtration.


"Setup Number 1 might still work, but it would require a different "clutch" mechanism than would fit in the pullys."


I bought an air clutch for mine but there's still some concerns about strength. I figure it needs to handle about 75HP so I may have to replace some of the internals and up the maximum psi capacity.

Mr. Dyers missed the point. A part time blower produces less friction, less wear and most important, less heat. A cooler intake charge can run tighter clearances and make more power. Plus it's about imitating the movie car's feature that most of the population thinks is pretty fricken cool.



"Now, Myself.. If I Had the money to build my own Interceptor replica, I'd actually feel compelled to go a bit different than what we see on the screen.."


I'll leave the 100% accurate stuff to Doug. I never had any intention of building a perfect copy so long as I knew the difference. A functional blower, 6 speed trans, aluminum wheels and humongous tires will set mine apart from the other clones.

That's not what they used in the Super Stallion. That clutch was basically the same type hydraulic clutch used in automatic transmissions.

so whats everyones elses views on this.is the blower just 4 show,or ?

Screw looking movie correct! Get a 500+ CI big block with an 8-71 blower. If Max would have had that, Wez wouldn't have caught him and made him crash the interceptor. This little baby will produce 4 digit horsepower on pump gas and no nitrous; add some nitrous and you can get really crazy! Forget about using those Bridgestone Radials though; they'll never hook up with this kind of power.

A big block Chevy in a Pursuit Special? Why don't you just shoot me in the head?
