I've decided to run a full size red top optima so I will let this go cheap. It is brand new and only started the car a few times. It worked fine even on an AEM w/ base map, cold weather, and on E85. Tuner /shop sponsor prefers full size battery since I am running electric water pump, huge Weldon 2035 fuel pump, and the set up must be placed in the rear of the car per NHRA specs. I heard retail jumped to $775 from $500 and then not even sure it is still available. I will let it go for $300 shipped. If your local you can try it for a few days...

Here is a link on the battery:
