I run a 780 cranking amp Anti Gravity ATX20. It spins my 13:1 Hemi over like the plugs are out of it. It will power the fan and wp for at least 10 minutes which is enuff to cool the car. THe alternator charges it fine, it survived Drag Week. it weighs 4.5 lbs and is supposed to last at least 10 years. Under $300. If you call AntiGravity direct, they will beat online pricing from resellers.
I have been checking these out as well! I worry though. I have a few loads. Electric water pump, turbo oil scavenge pump, small radiator fan, EFI system coil on plug and injectors. maybe the next size up??
