Notice a trend here?

I have the same old battery in my car that it came with, I just moved it. It is probably 4 years old and still holds a charge just fine, hasn't needed a jump once in any weather. I am also confident that it can support my ignition system at high RPM without the aid of the altenator. I can't say that about the small batteries. I am assuming that everyone is running them mainly to save weight and get the associated power savings that goes along with it. Consider this though, if you are saving 20 lbs going with that battery, and the statement is true that a 100lbs is worth a tenth in the 1320 you are less than a 2HP advantage from the weight loss. If you kill your altenator for the run and go from the batteries power, you are probable closer to saving 3-5HP and possibly more, I have heard alot of different numbers on that over the years. Also, by moving it to the back, you have more even weight distribution and can place it directly over the most significant tire (RR).

I am interested in anyone elses opinions of what I am talking about. Try and shoot holes in what I am saying if you can, I am always open for a better way of doing anything.
