1 Kinetik Hc 2400

1/0 guage everywhere except from the amps to the distro. block is 4 guage

Did you do the Big3, if you didnt even with a H.O. Alt, your power is gonna be bottle necked and you will not get the advantages of the H.O.Alt.

Edit: Also most H.O. Alts, dont put out full power at Idle, usually about 1200 to 2000 rmp, but you can fix that by going with a smaller Alt pulley.

do the big 3?

clean metal for grounds?
