Has anyone tried the Dyna batterys from Performance Distributers. It only weighs 13.5 lbs as compared to 35 lbs for stk so at least a 20 lb saving off the front of the car. Twenty pounds is alot when u think thats off the front. For my street car this makes alot more sense then a on/off switch and the battery in the trunk. With the switch water can get into the car when u wash it or if u drive it in the rain and Im allways worried about forgetting to turn the switch off when u get out of the car. I did that a few times on my Big Blk 93 when I was at the track. I say water can get in because only the push/pull switchs are still legal in NHRA not the turn style. Plus u have the switch handle sticking out and were do u put it without modifying your license plate and pissing off a cop. According to the comp. its compltetly streetable as the sales guy I talked to said he had one in his f-150. Cost is 160 so its not cheap but if u need a battery anyway and are anal as hell like I am about getting the weight off the front of the car it sounds like a good idea. Like everyone says 5 lbs hear and there and before u know it its a 100 lbs and thats a tenth. Im at a 12.1 at this point so a tenth to me is huge. Also I only have 300 at the wheels but she runs good because she weighs 2800 with me out of the car and im 200 lbs, 3000 race weight. Ive down everything I can think of to bring down the weight and still have a nice streetable car except, tubular A-arms,racing seats and the battery and front coil overs.
