I HAVE MSD QUESTION

can the 12 volt Alt be used with the 16 volt battery ? Also will anything be effected such as tack water pump fuel pump ect by using the 16 volt battery?

I run everything off 16v.... except the fuel pump, I run it off of the 12v lug........big ass fuelpump..... its happier on 12v

Ok I missed that part about changing alt, but will it hurt the 12 volt starter any ? I know we use to change the battery from 6 volt to 12 volt. We did this on the old volks wagon dune buggy and it would whipp over like grazy but, would also burn the starter up !

wont hurt it a bit

Have you ever seen a 16volt starter.



Nope, not usually


Kidding aside. Everything on the car will be fine at 16 volts. If you decide to run an alternator then you need to check with the manufacturers and see what voltage their parts will handle. On the Rock batteries we run it takes a third of a volt per cell more to charge than they produce which is about average from what I've seen.

no 16 volt starter ! well dang it bobby !

I was just thinking that maybe that a heavy duty starter would be in order . Maybe larger armeture more windings and brushes for the add voltage.

They said they had it set at 34 dreg. with a crank trigger, when they dyno'd it but when I hooked it up to my 7al box it changed to 50 dreg. so I readjusted it to 34 on my 7al box and it's been a beast since.

GREAT INFO HERE. Mine on the dyno was 38 degrees with an old 7al. Once in the car to my digital 6 was 34 degrees. Thanks all.

One thing you have to watch with a 16 volt is running your electric stuff with the charger on , water pump, etc. That 19 volts of charge will burn out lights in delays boxes etc , there is a step down box you can buy but its best just to have your main disconnect off while charging.

Now that its been hashed out i have noticed some delay with mine since switching from a 6 al to the 7al 2 plus , i don't have any starter drag but there is a noticable delay from when the on switch is turned on until it fires.

how about 24v? i know some truck pullers that use 24 on the starter

New 12volt High torque starter fixed his problem.
