Best Battery with no alternator?

428tom · 08-18-2010, 04:50 PM

Just wondering what the best battery to run if you don't run an alternator,that is with a 12v battery.Is there any big gains to be made with a 16v battery.

If I were you I would try it before you do away with the alternator.
On my car it's good for 1 tenth the wrong way.

Art, have you tried with a 16V?

I have a new "Performance V" 16V but as my car is under construction, I can't comment on battery voltage life. My research was that it would take a lot of runs to get down to 12V and I checked all the amps my car was using and one 16V was more than ample. The fact I have a 4-speed helps as I don't have all those driver aides with an auto trans which use up a lot of energy!

Jeff I haven't tried the 16 volt system. It might be enough. I could eliminate some of the current draw, My fuel pump is total overkill (think thats where most of the ET is).
There are a few other things I want to do first.
Real intake manifold. And a final drive ratio better than 3.73

The '87 Shelby Daytona Z I raced in A/FS had a factory Getrag 5 speed with 3.91 ratio. As I recall, with 20" slicks it went through the lights somewhere around 6200 in 4th . Yours is a stick isn't it?

No both Tim and I run an auto. I'm just starting to get in my powerband at 6200 I cross the line at about 6400 at 105 mph. Still using the 20" slicks
