You lost me here, Bill ... why does a racing motor need alternator output at
idle ?
My street engines don't charge worth a darn at idle, and they spend a whole lot
more time idling than I'd expect on the race track ...
BTW all "points replacement" ignitions are not created equal ... Crane promises
operation down to 8 volts, while my old Allison crapped out around 10. But a
healthy car battery has to be pretty well drained to even get down to 10, so no
problem with not charging at idle unless you plan to let the engine idle for
several hours.
