Powermaster 150 amp 1 wire
13.5-18.5 volts adjustable regulator. 8148 part number. Puts out I think 60-65amps at idle and little over 150 full throttle. Not that it ever needs that many amps. But the smaller units don’t charge enough at idle to do the job.
I run a 16v battery so I have it turned up to 18.5 volts. Charges great. I don’t need to charge at the track on race days.
This is a relevant point! I pullied the alternator so it's at maximum recommended RPM at my trap RPM. This way it has a decent but barely adequate 'idle' charging output. But then my trap was high @ 8200 engine speed.
