Optima batteries

I am going to redo trunk area & going to use just one battery.The optima was recommended by a round de round friend. For a car with NO charging system witch one does people like, red or yellow top? Or is there a better battery?I am hoping to find one that will start car many times & run fan & water pump without charging at track. some say to use 2 batteries 1 for motor & one for fan & water pump. The one I 'm looking at is yellow top with 870 ca with 120 min. reserve. They have one I really like except price & it weights 60 lbs.
