Up higher in this thread, there is a real electric one mentioned. If you are talking about a 4-5 HP motor with a proper compressor for an engine about the size of 1.8L then it's a real thing. An electric motor of that HP takes about 4-5 kilowatts. 4KW at 12 volts means you need 333 amps. Of course, this scales up and down with engine displacement.

Higher up the thread RAD is pretty firm that he does not want to go with fuel injection.  So within the scope of the most recent conversation there would be no TPS unless he piggybacked it onto the carburetor somehow.  One way to avoid all that is the system linked a few posts up.  It only engages at full throttle eliminating the need for a TPS but i'm guessing it would be a bear to tune a carburetor for the very sudden increase/decrease in air flow.  Lots of good conversation on the topic if you care to re-read the entire thread.
