I went to the track the other day and say alot of engines being run with no alternator.why would someone do it and what for.what do you gain from not running a alternator belt. Thanks

 

they beleive that cutting out the drag some gain would be realized, which is quite to the contrary

how would one keep the electronics at a constant level of current and voltage then???

one could have a the baddest battery ever, but batteries do discharge and lose voltage and current over time, but who knows dependeng on your electrical suystem requirements you my and or may not benefit from such

i would keep an alternator regardless of the 'weight savings' and the other possible benefits associated of runnign w/o one

 

16v Battery Sucka...

Taking of the alternator lightens the rotating mass making the revs faster and make a pony or two. ..just like taking off P/S and A/C.. a battery charger will keep your batteries charged..this is common sence any real racer would now this.

 

the drag is not the same with an alternator as with a/c or ps

the alternator is not pumping a fluid

any real racer DOES know this

16v battery or not, doesnt matter it still gets discharged, you cant escape physics

as for a battery charger, yeah they keep batteries charged, when plugged into an outlet, either you have one hell of an extension cord or you plan to keep a generator in the back seat to make it operational

while your at it, why not remove the oil pump, and the trans too, theres alot of drag to free up there

 

You only need it to hold aaaround 14.5V...and itll keep 14.5v through the traps...then you recharge it.

 

i wouldnt want to sacrifice a loss in current

to each his own

 

The onyl way to do it would be to datalog both setups and measure the drop.

 

alot of all motor cats still use a 12v battery. ours is at about 12.3 volts under load going down the track. and this is a walmart lawn mower battery ($15) not a high priced dry cell or something crazy.

next year im getting something nicer, most likely convert to 16v.

and to answer the og question, it all depends on the cars tuner and mechanic. personally i see it as just another thing that can go bad during a weekend. i like to cut down and if something isnt a bare necessity then i dont use it. its just extra weight and more drag on my engine.

 

How is there even an arguement? Alternator still is weight and still causes drag period. We are talking about race cars not street cars here. Run 14.5V, lasts through the traps that's all you need. Take it back to the tent and recharge. What's the big deal?

 

exactly.. its an easy gain on a racecar
