Can you run a serpentine belt if you run a electric water pump and alt? The engine will have no a/c compressor, fan hub or mech water pump. if not I'm just going to get rid of the alt.

Thanks for the advise

How does an electric alternator work? And what is the truck being used for?

If worse comes to worse, save the weight and complexity of the alternator, run everything off your battery and just throw it on a charger in the pits.


But there's a lot of serpentine belts out there... Gotta be able to find something that works if you look hard enough. The tensioner set-ups on these engines are pretty forgiving; I'd think that you'd have a several inch window when it comes to length.

Provided that you can still use a tensioner?

Thanks for the imput. Some rules state for the 2.6 you can use a electric water pump and electric fans but still have to have all acc. hooked up except a/c compressor (ie fan hub and alt) want to free up as much hp as possible but still stay in the rules but running a fan hub and alt will drag hp down not sure how much. will 2 800 amp batteries be good enough to run a elec fuel pump, water pump, fans air locker pump, etc without having to charge it between runs? the truck is going to be a puller only with a 3.0 engine (internals) with a 2.6 charger.

The alternator doesn't require nearly as much hp as that fan. I would suggest just bypassing that and keeping the alternator hooked up. $.02
 
Why, not get a charger to charge them up between runs. I'd just get rid of alternator.
 
NADM says in the rules if I read then right 2.6 has to have the alt hooked up in factory location. so I guess what I'm trying to do is get a belt that will let me run the alt, tensioner, crank pulleys along with using a elec water pump and bypassing the fan pulley without interfearing with anything.

Most street classes (NADM 2.6 and 2.8) require that a truck be streetable, and it can be road tested if it deemed necessary. Good luck driving a truck on the street any distance without running some sort of alternator to charge the battery/batteries.
 
I put something around 150 miles on my 12v after the alternator died. No lights or anything, but it ran. I just let it idle when I went in the places I had to go...

Stock lift pump?

I'm curious how long it would last running a FASS, water pump, and cooling fans. Those fans draw a relatively large amount of current (generally speaking).
 
My good ole' 12 valve can drive all the way from the beach to Phoenix, Az with no battery or alternator at all. :rockwoot:
 
Rules don't say how far you have to drive it. Could be a grocery getter, that is just down the street.

Yeah, I just had to throw it out there:D

I've actually wondered the same thing.
 
Tring to see how much all elec items will draw. (amps, etc.) sounds like it I will have to use the fan hub, crank, and alt minus a/c. if it had to do any driving to make it "streetable"
 
I've driven my 24 valve 80+ miles with the headlights on in the middle of the night when my alt went out, I only have a single battery in it, granted it's a odessey 2100 cca battery.
