When you race Dave 30lbs could be a 1/10 of a second. The battery is the cheapest investment I have made searching for those 1/10th's as others addicted to drag racing will tell you. Why would they even make these batteries Dave. There must be a demand for them. lol. They now have lithium racing batteries. There cost is 4 figures. Used in all kinds of racing machines. They have a 4 lb battery. Does the same thing. So a guy like you Dave probably will never understand. Always looking for that next mod. Always looking to cut a 1/10th off at a time.
I will do you one better Dave. Add up those mods listed in my sig times two. You could own another SRT 6 Dave. Do you really think buying a battery is a big cost to me? And even with all that it will run with cars that bring 6 figures. So it's worth it to me regardless of what others think.
