Bernie:
yeah, whatever you give back to the crank, ya gotta replace with power from
somewhere else! And (if my old eyes are reading that little graph
correctly), that's a lot of electric power-- and big wires, as you say. But
a powerful, SHORT DUTY-CYCLE electric motor is a lot smaller per HP that the
standard-frame stuff that we normally see.

Glenn,
I think you are talking 15--30 hp to drive a pump for a 4-500 hp motor.
That would be a pretty good size motor,w/big wires!

don't need onboard charging. I really wonder how much power it would take to
drive the dry sump punp......now you got me thinking.....Jim and Bernie will
tell you that's dangerous!

find some good numbers with a little research in my library. A "total loss"
electrical system is frequently used when converting a "street" engine for
(non-"endurance") racing. It consists of running the battery without an
on-board charging system (which consumes power), and doing your charging in
the pits. I'll see if Dave or someone offers some numbers for lube system
power consumption; if not, I'll see what I can find.Russ, #1226B
