Why do you need so much volts?
If you want volts get a better bigger battery?

Are you sure you are reading the voltage correctly... Voltage should be 14.4 volts, but if you are reading a difference than that (like from a AFC), it may be the meter or device.

Check with a digital multi meter while the car is running. That should give you your real voltage

yes i was using my AFC. i will check it while at idle thanks mark ill get back to you i checked it before that way but ill do it again

wanna sell one of your alts?

edit:
you can get a custom alt to have a high output. excessiveamperage.com you can get like 15volt 300amp alt i believe, its like $300+ for them.
