24 Volt starter for Chevy V8

I am entertaining the idea of using an LS3 series Chevy V8 on my
Seawind
project. I would prefer a 24 volt system-battery and starter because
it's a
20 ft. run one way from the battery to the engine. Also I've already
purchased fuel gages/probes and lighting/strobes for 24 volt. Does
anyone
know if there's a 24 volt starter available and ready to bolt on for
this
type of engine? A manufacturer and possibly supplier would be
appreciated.
I know I would need a 24 to12 volt converter to run the electronic
ignition
system and they're easy to find. I'm still a little undecided on what
type
of engine I want, but I need to make up my mind soon.

Some large trucks use 12-volt systems and 24-volt starters.
They have two 12-volt batteries, connected to a series-parallel relay
that makes the connections necessary for starting.
You might be able to work up something similar but opposite. 12
volts for starting, 24 for run. Two smaller 12-volt batteries in the
same rack or box, and a heavy relay to shift things between starting
and running. I can't remember the wiring diagram for the relay, but a
truck shop might have one. I've been away from the industry a long
time now.

Truck needn't be so large. I remember exactly such a configuration on a
Mercedes 608. The relay was right under the driver's seat, the loud
"CLACK!" always made me jump when I started them the first time after
some while.

If you are using a non-geared starter, with copper windings, it will
take 24 volts and will crank like crazy.
HOWEVER, your local auto electric shop SHOULD be able to get you a 24
volt starter to fit

If you have the room and can find the appropriate size battery's you
may not need a 24/12 converter. When I converted VW from 6 to12 I
would sometimes wire 2 6 volt batteries in series under the seat. Just
taped 6 volt off the middle for things like wipers that were harder to
swap out with 12V units.

We would also leave the 6V starter and just run 12 volts to it. They
spun a bit faster and lasted just as long as a 6 volt starter on a 6V
system.

Same scheme might work for you as well?

Yah. I come from Northern Minnesota, up north of Bemidji. We
used to regularly put two batteries in for the winter when we used
6 volt systems. That six volt starter would crank right up when you
put 12 volts on it. I would imagine 12 and 24 volts would work the
same. The only time it would be a problem is if you used magnetos
with an impulse coupling. The impulse coupling might drop out
while cranking and give you a spark advance just when you don't
want it!

Just run 24vdc to the 12vdc starter. With the long cable run you may
need the extra juice. When we lived on the N.M./Colorado border some
years back I converted my I.H. truck to 12vdc run and 24vdc start. The
batteries were in parallel for charging and running and series for
starting. Made a big difference at -30° to -50° F. You might contact
these guys about the ignition and starter:

If they don't have what you want they may be able to direct you to
somebody that does.

Find an auto-electric shop that's been around a while & still overhauls
starters & ask them to wind a starter for 24V operation. The old hands
in the shop wouldn't have any problem doing it.

You probably won't save 4 pounds of wire in the whole plane by going 24V
& you'll probably spend a *lot* more money, but if you like it, go for
it. :-)

To answer the OP question. Try IMI performance Products
http://www.hitorque.com/
They have a complete line of starters in every configuration imaginable.
Very reasonable in price. Basically, they use standard Denso
bodies/motors/solenoids with their own design front ends (just like
Chevy did for the Corvette starter)

But if he has 24 volt avionics he's better off running the whole thing
24v than using a 12-24 converter to run those.
