ok, some of this may be just from ignorance, so bear with me please
was reading about GM's new DOD engine (Displacement On Demand, uses collapsible lifter's to turn a V8 to a V4, and a V6 to an I3 when full HP isn't needed, think of that exhaust going from a gnat to a lion when the pedal is floored), and then later i read a post on this site (i think it was XECUTE's "I'm going to Blow my Budget!" not sure though, might have even been a different site) that talked about a supercharger that had an AC clutch on the pulley so that it was only activated at a certain time
those both got me thinking about a BOD engine (Boost On Demand), where you could flip a switch, have the supercharger and all related systems engage and go hauling ass down the road, then when you were done burning the ricer or the V8 next to you, switch it off, and have a nice mild I6 to get you down the road
here's where the ignorance comes in:
1) i know there would be compression issues, NA engines have a higher compression ratio than forced induction engines
2) i don't know how superchargers engage normally (not for sure at least, i'm pretty sure that because they build boost in relation to RPM, they are on all the time), so i don't know if there is something like an AC clutch in normal supercharged systems
3) i don't know how AC clutches work, i'm pretty sure that there's a solenoid or some similar thing that engages the clutch when you flip the switch to turn on the AC
is there a way around the comp. issues? how much engineering would this take? what am i really missing (besides my mind, i saw that thing just the other day)? could this work? am i really late in current events and it is already under someone's hood? am i the only one who thinks this would be cooler than wakulla springs, fl on a hot summer day?
PS - if this is possible, and is a new idea, and someone else wants to "borrow" it, please feel free, if it will work, i won't be able to put it into use for a while
