i know the idle is caused by weak spark and injectors not getting enough power to cycle properly.
I'm thinking a high out put alternator would also help with the car's overall performance too.
Now all I have to do is find them....

H.O. Alts usually sacrifice a little power in the low end and boost it up in the high end. Along with the added strain of having to turn a part with even more resistance, the H.O. Alts don't usually last as long either.

you might get a stronger spark and SLIGHTLY better response from the injectors getting a voltage boost but I doubt you would notice it. Probably better mpg rather than HP.

I would assume a slightly larger load on the belt and therefore the engine?

i agree, it would make for a higher load in the lower RPM range, but once you got it moving, i'm wondering if it would provide more than it is is taking. Ya know. I know road race cars have crazy alternators, especially when you consider the lack of accessories. I'll have to talk to some of those guys and see if I can get a decent reason as to why.
What do you guys think about making the alternator pulley smaller?
It would make the alternator spin faster at idle, therefore making a little more power, but would it cause a problem in the higher rpms?

Yes, once up to speed, it will definitely make a lot more power.

Some HO alternators have a higher efficiency than the OEM(at the expense of life span) and will present a smaller load on the belt for the same amount of power.

Overdrive pulleys increase the rotational speed in relation to the engine. Basically your idle RPM should make the same current as an RPM 30% higher would make with the stock pulley.
This comes at a cost too though. If it spins faster, it ages faster... And yes if you rev the engine to a point that originally would have met the top rpm for the alternator, with the pulley it will exceed that point and probably just age the coil even faster.

Wow Don't waste your money
Hey just a few things
A. alternators designed for road racing are a different animal than alternators designed for car audio.
B. purchasing an alternator for car audio is an extremly large purchase (very expensive) if you want one that is gonna do the job properly.
C. Go buy a deep cycle blem battery at Electro battery in St. Petersburg (23rd Ave and 32nd St.) for $40 or so and wire it in between your front battery and amps and 90% chance that it will solve your problem.
Unless you have an extreme system you should not need to purchase an upgraded alternator
But if you either do have an extreme system or just have money to burn and want to buy one google HO Alternators and Ohio Generators, these are the two top alternator companies in car audio today and you can get a quote for your vehicle from both companies on line
