Running an alternator

Ed Wright · 10-01-2017, 12:42 PM

Mine ran faster with it turned off during the run.
Even a little quicker with two 16 volt batteries, and no alternator.
Your results might vary. Don't know if you don't test.

I do it for consistency, not necessarily ET.
On my 2300 turbo, you could hear the idle pull down when you switched on the alternator.

The Monte has never had the alternator switched off. Not even on record passes.
It dials pretty well, and follows along with the big boys' ET's.
Of course, it has the stock computer (which Ed re-did for us), and also stock ignition.
Plus the trans doesn't use any juice either.
So, who knows, without a-b-a testing within a reasonable time frame?

The only advice I can give you is.....when they start hot lapping your AZZ, you will be a very happy racer IF you have a very Functional charging system. ........

I have no problem making three "hot laps" with two 16 volts.

I don't run an alternator. I have a 16 V battery. I ran 11 rounds at one of our Southern Stock Super Stock Assn races last year in one afternoon. 2 rounds of qualifying won the first race and lost 2nd round in the 2nd race. Battery was charged between rounds and I cool off with a separate battery.

The hot lapping Mr Derby City is talking about is called winning rounds late in the day. That is something most racers are never lucky enough to experience. If you have not experienced a late round push to get the racing over with for the day, then you do not know what real hot lapping is. Listen to his advice about running an alternator because he has been there and done that.

You don't think we know what that is?

Everyone knows what 3rd, 4th, 5th, or 6th round is but how many have been there and actually got to run that many rounds? Unless one has actually been there, they may not know what real hot lapping is.

Not saying that I'm any kind of a heavy hitter or anything , earlier this year I doubled up in a local Super pro and local S/ST event with my car that has no alternator but does have two battery's went 5 Rounds in Super pro and won in S/ST. There was only one class between the two classes ( motorcycle ) that was 4 time runs and total of 9 rounds that night. I would put a charger to the car when fueling but had no trouble cooling the car or starting . Towards the end of the evening I was having ( being a old guy) a little energy trouble as the gate time was 5pm and the final in S/ST staged a 2:30 in am..... LOL

The reason I have no alternator was that back when i ran with one third round of a team race the alternator split in half 600 ft out. When it did that it killed my MSD box so I was done that day and had $175 repair on the box. So I just mounted another battery out back and give up on the alternator. It kind of helped my 60 ft. removing weight off the front and putting 45 lbs in the rear..... That's my two cents....

Been there. No problem with two 16s.
