i have a 200amp alt from MCR. I just had it tested about am onth ago after it being installed for six months. IT puts out 130amps at idle and 185@ 1500RPMS so im sure at 2000 RPMS it should be at least 200amps
i got my alt tested at two different places actually. 1 was at advance auto parts. there machine is good up to 1500rpms.. and then a local machine ship.
