Greg,here is the site to the one's I was telling you about to upgrade your MSD 7 box,they claim they can make improvements to a new box. www.techwestracing.com when they done mine it was a $125.00 if nothing needed replacing,they are good at what they do. PS I am going to have to go back to their site when I have a little more time,they have some good tech articles.

I'm weighing the idea of installing a Model 30 battery in the factory location - to lose 20# of weight on the nose - vs moving the 40# battery to the back and adding another 20# worth of cable + cutoff switch + mounting provisions. This looks like a 20# weight loss vs adding 25# more weight and juggling 65# to the rear.
that sounds like a great plan for your situation. With out much draw on the battery in a warmer climate, it should work great. My big question, and I plan on calling Odyssey, is just how does the ER30 compare to the 110 reserve of the Optima that is now in the car. They claim the ER 30 will hold higher voltage for more of the reserve, a very important thing.

Greg, please post what you find out, I am very interested in the Odessey batteries to lose some weight on my car. I have 2 yellow top optimas now.

Will do.
FYI.....have never used anything more than a std schumacher (spelling?) smart charger on my Odyssey Batteries.....just don't let the charging voltage go over 15-16 volts for an extended period of time

If any of you guys running two batteries are also running an alternator I would ditch the 2nd battery. At least try it for a weekend and have your extra battery with you. Monitor the voltage and see how it acts, if it gets questionable swap the batteries or add it back in. Easy free weight loss right there.

The only down side I have found on the 16 volt battery is,the chargers do not have a fast or slow charge and I think they only charge slow .

Greg, isn't your battery(s) in the rear??...stick with the Optima's..
I use Interstate's 1,000 amp rated...as long as I kept a trickle on them, they lasted forever with plenty of start power...no bigger than the Optima's..and a lot cheaper!
I moved the battery up front to get the chassis calmed down during launch. The move put me at 53 percent up front, but the car likes it and still hammers the wheeliebars pretty hard. Sooo,,,,,, a bit lighter or same weight battery is my objective,and one that will last. When I call the manufacturers tomorrow My questions will be- how does the ER30 compare to an Optima 110 reserve battery, and can I fast charge with the old Schmacher 20/50/200 charger between rounds, then maintain or top off with a smaller AGM charger? Those faster AGM chargers are expensive!

Here is what I have found so far Odyssey er30 $280, light but short on reserve time. Odyssey er40 $310, better, but has 87 min reserve at 28 lb Braille B3121 $179 at Summit 75 min reserve, 21 lbs. This is the way I am going to go. A 25 amp charger is supposed to bring this battery back to full charge in 30 minutes. For what I do, it SHOULD work. If it doesn't, then it goes in my daily driver.

What does the reserve time mean or whats its function? I'm not sure if it means what I think or not.
