Im asking about this stuff because I want informative answers please dont reply if your gonna make stupid comments and expect me to argue with you because that is not the purpose of this thread Thanks for all the intelligent answers.

Ok so I recently saw Mad Max and I was wondering about the terminology of some of the things used on the car. I think it was a Ford Falcon but correct me if Im wrong. I would've googled this stuff but Im not sure what some of it is called and if there's even a company that makes kits like this for any applications import or domestic. Also Im pretty sure this isnt fantasy movie stuff that was done to the car I believe its been done by real people on real cars.

Anyways there is a scene when he's cruising down the road with the blower deactivated and he pulls up on a red switch next to the shifter that activates it and suddenly the car comes alive. What is this type of doohicky called? Does anybody make a similar kit for modern day cars? Is the difference in gas mileage enough so that this set up is worth doing or is it better to just get a blower thats always running?

How is the blower activated/deactivated? <<< This is the most important question. I do not understand how they got it to be turned on and off over and over in the movie.

How did they alter fuel/spark for when the blower was activated deactivated? Im pretty sure that fuel injection wasnt around when this car was built so there couldnt have been an electronic way to alter fuel/spark between when the blower was on or off. Im sure they did something which got the carb(s) to dump more fuel but what? Also the only way I believe one of those old school domestics would've retarded spark by using a timing light and manually taking a wrench to it. Is there a device which can be attached to the distributor to retard the timing once the button to activate the blower is pushed?

After having writting all this I realized that very little fuel/spark changes would have to be done if this type of blower setup was only there to add say 4-6 psi of boost and that the car probably wouldnt have any changes made to it fuel/spark wise.

Also would this on/off blower setup be there only to compliment an already badass NA setup and give it more top end grunt or would it be there to give better gas mileage while off the boost?

Thanks again.
