Alternator?
 

Do you guys run an alternator in your race car? If so, can you explain the set up? If not, can you explain how your wiring/battery set up is configured? I'm weighing the pros and cons to both.

Thanks,

Yes, we run an alternator. They are one wire alternators, and charge through relays, so that they do not keep the engine running if the master disconnect is turned off.

I run a Powermaster 1-wire alternator on the 'wagon hooked directly to the positive side of the battery. Nothing fancy, but it meets the rules and I have had no run-on issues. Most aftermarket 1-wire units work basically the same way. I'm also using a 6 Amp battery charger after every round.

I'm looking at a Declo 50 amp idle / 105 amp WOT. It's bigger & heavier than the mini Denso 45 amp I had previously as I found an OEM Volvo electric fan & shroud that fits my radiator nicely. It should cool nicely but the draw is 40 amps extra over what I ran previously. The Delco alternator is 11.2 pounds vs around 5-6 pounds for the mini's. This is a 16 volt unit.
Anybody run a cog (not serpentine) alternator? Have a source? I found this

Don't forget about the one way diode if you are using an MSD so that you'll be able to stop your engine!
