the blower set up

I've often wondered...suddenly forcing that much boost at a high rpm...? Your motor would blow. Besides what purpose would it serve to not just have it running all the time like all blowers are set up? Engines do run more efficiently with forced induction which would be more helpful in a place where gas is scarce.

Street supercharging is probably one of the most misunderstood topics in the automotive world. First off, the Roots type blower can not be turned on and off. It is a positive displacement air pump that moves a set amount of air with each revolution. The amount of boost is controlled by over or under-driving it in relation to the crankshaft RPM's. On the street, most boost levels will be in the 6-8 PSI range. If the engine is properly built, it will stand up to those pressures. The real problem is with detonation. Any more then 8lbs and you start pushing the limitations of pump gas, even 93 octane. A properly built and tuned supercharged engine may actually increase fuel efficiency. The real problem in Max's world wouldn't be the scarcity of fuel, but finding fuel with enough octane.
