Voltage regulator

[Barry Tisdale]

Any electronics gurus out there familiar w/ voltage boosters / regulators?  There's a manufacturer out there specializing in aftermarket parts for turbo cars that sells an adjustable voltage regulator that will supply 12-16v (@ up to 40a) from a battery source of 8-12v, to boost the stock fuel pump output.

Any idea what circuitry is involved?  The price of this gadget is $250 or so, which probably means you could put it together for $50 (?).  If the stock pump is not up to the needs of a hopped up engine, this seems like a neat gadget.
