Well my charging system is getting its ***-kicked by my fans, blower fan, and stereo. I will prolly just go with a 130A + overdrive pulley as that should provide enough amperage to keep everthing okay with the stock crank pulley.

How much will it increase at 500rpm idle speed with the 130?

 

hey buddy you will not be dissappointed. my 130 amp alt takes care of it.with the 105 my gauge would drop to 12. now it barely drops below 14 with ac,stereo,lights,and fans.

 

M'kay cool, if I end up keeping this truck... I'll go for the 200A and an ASP pulley for more amperage and power.
