I was thinking of something similar, but decided that I would try to focus
on finishing off the EFI system first. A good place to start for 12V to
What ever supplies are in some of the mid priced Auto audio amps that has a
nice PWM supply, they put out a bunch of power, and have a nice case. I
have seen some pretty small ones in a magazine, that did something like 58
volts at 8 amps. It was not very large and looked prety simple.
