Would it be possible to build an electric turbo that could just be switched on when needed? Would you need to vary the speed with the throttle or could it just blow full force? Or would this idea simply take to much horse power for an electric motor to handle?
 
Hi Denny,
 
There are a number of companies selling electric superchargers, but most of these will require some imagination to see any actual results.  There is one I've seen, called the eRAM that looks like it could possibly do some good, however, it also pulls 57 amps !!!!  Eventually, when battery and motor technology advances a bit, perhaps we'll see a day where these things might work for us, but I don't think we're quite there yet.  
 
Anyone who saw the movie Mad Max saw the supercharger with an electric clutch that could be turned on and off.  It's my understanding that was just something they did for effect in the movie, but I have wondered if it wouldn't be possible to do something like that with a centrifugal supercharger and bypass valve.  It's probably not worth the extra weight and effort though. 
 
Cheers,
Rusty
