I put a Denso # 210 0106 60 amp on my race car. Pulley it to run max rpm at your rev limit for decent results. Since i don't have a lot of draw on my system it works great. The wiring is very simple. I used spade connecters at the alternater rather than the 3 wire teeminal sold for the alternater.
One wire goes to switched 12v and one to the charging side of the alternater if you run a very large zero loss output to battery. Otherewise you need to go seperately to battery so you get true voltage the alternater is sending to the battery. I used #4 welding cable to make sure i had a zero loss from output lug to battery +.
Whether it will do the job or not for you depends on your setup. I run a big radiater fan some, an electric water pump, MSD7 a fan for me and other gadgets like airshifter , box, and tail light. The battery stayed at full charge all day.
