Question

I been gone for a couple of years, so can someone tell me why we rasied the stock and sb voltage to 15.5?

some newer cars charge at 15 with stock alt

Ok good enough for me just curious?

thats why ya still have to use 12v bats only no 14v bats

who is this rs s-10 guy?

So are you saying that you can't run 14v battery in sb4, being that when the bass hits 16v batt. will be below 15.5 then say go, during a 30 sec. run will never be above 15.5. Making it a legal run right?

nope.... 12v bats only

So much for my great idea, it sounded like a good idea. Back to the drawing board.

this is in the rules have you even reaqd them before spending money

Mr. Sandman I was told to talk to you, the rules says 15.5 does not say 12v batt. only, also says size does not apply to unlimited classes. All that should matter is that my voltage does not go above 15.5 I talk to Jenissa she agrees but want me to ask you to

ralph has put out that you can not run batts that rest over 12.9v

even though you can run 15.5 you must achieve this with an alternator and not the batts internal voltage itself

lets not forget there are general rules and then rules for each class

I understand where can I find this information?

the main homepage it says rules click there

**The physical size of each battery is limited to 800 cubic inches (13110 cubic cm) or less. (Height x Length x Width. Excluding the battery terminals.) The physical shape of the battery is irrelevant. [b]A 12 volt battery is defined as a battery that has a nominal terminal voltage of 12-Volts, consists of 6 internal series-connected cells, and is lead/acid or gel-type.[/b] A 16 volt battery is defined as a battery that has a nominal terminal voltage of 16-Volts, consists of 8 internal series-connected cells, and is lead/acid or gel-type. A battery shall have no more than two “unique” battery terminals connected to the system, one being positive and the other being negative. Batteries with more than two posts connected to the vehicle or system will be counted as multiple batteries. Batteries that exceed these 800 cubic inches or exceed allowed number of cells will be considered multiple batteries. (Example: 801-1600 cubic inches is tow batteries. 12 volt battery with 7 to 12 cells would be two batteries, and so on).

14 volt batteries are 12 volt batteries with 7 cells correct? sb4 clearly states unlimited is for size goes, if you don't mind me asking where does it say a battery cannot rest higher then 12.9v

he has it highlighted in red nominal voltage of 12 ... that means up to 12.9

at 13v or higher sb5

lol thank you rowland i was about to me like WTF are you kidding me

Im rebuilding an don't want any issues that's why I'm here asking guys like y'all

It's good that you ask , but also I recommend to know the rules of your class .
Good luck on your SB4 built , SB classes are tough . They were meant to be stock and fun , but they could be tough .

they are fun forsure id like ta see the time raised ta 60 sec.
