Well only on a need to basis, more windings might be heavier to spin but essentially amperage is on demand, so if your car only needs 80 amps to run whether you have a 240 amp or 120 amp alternator the demand is still 80 and the alternator will only put out 80.
I might go with 170 we'll see

I can idle at 800 rpm with all lights on and dual spal fans on hi and it still holds 14.5 volts.
Considering getting one of these in the near future. My 2011 is stock under the hood. Is there any reason to go with a 240amp for a stock setup or is that for cars with extra electronics or racing applications. Just curious.
Sorry for the delayed reply. If I miss one, then I miss them all.
No reason whatsoever. It's overkill and added cost to boot. If you can't justify it with electrical load, then it's not recommended. You'll hold the same voltage between the two until your load becomes so great that the 170 can no longer sustain it. It is rare that I recommend it. The TT cars with scavenge pumps, extra fans for trans and oil coolers and things like that would make me start to recommend the 240

Thanks!
The 240 will put more load on it and push the 4-rib more toward slipping, but not technically harder on the actual belt. If you've got a direct/flip/secondary drive, you might consider the C5 A/C bracket to get better belt wrap on the balancer.

Bigger is not always better. The 170 amp puts out more amps at lower rpm than the higher amp versions.

Thanks for the feedback and

I thought he shipped mine so fast because I ordered it on my birthday LOL! I got mine today and it looks so beautiful I decided to let it sleep in my bed tonight. I hope it knows we have to get up early in the morning for install.

PS. Don't make fun of my sheets
I guess as long as you're not sleeping with your "tranny" you should be okay with just an "alternator" in your bed!
These things are real eye candy and it sounds like they work as good as they look!
I think I'm going to order me a black one soon.
Free bump for BLOWNBLUEZ It shipped a lot faster than expected! Prob delivered in 2 days or so..
Thanks for your feedback!

I never considered sleeping next to my car parts. If I did, it would have to be on the couch or on the floor with the dog because the wife wouldn't be havin any part of that.
Don't get me wrong. I wear the pants in this house.
She just tells me which ones.

Let me know when you're ready. There's currently roughly a 7-10 day wait.

I installed my alternator this past weekend and could not be any more pleased with the technical support and quality of the product received. I had the alternator on my door step within two days of ordering.
Background:
In the Alabama heat with a "full" load on the charging system I would often times get the annoying check charging system message.
I have a high dollar forged longblock with a rowdy cam, ATI dampner, and a considerable amount of engine bay heat. I went with a reman from O'Reilley when the OEM alternator died. The reman would make it for 3-4 days and crap the bed at inconvenient times. The average voltage output on the remans and the OEM peaked at 11.5 volts with high beams, fan, AC wide open, and the car at operating temperatures. It was common to see 10.x values on most days.
After the installation of this alternator I've got a rock solid 14.6-14.7 volts at idle and at cruise. Additionally, my inside and outside lights are brighter, my nitrous solenoids and supporting hardware have consistent voltage, and my standalone fuel system is getting 14+ volts as well.
This could very well be one of the best mods for any car regardless of modifications or purpose.
Check out the pictures below:
Note: The finish on the alternator is machined. The odd coloration in the pictures is condensation from the 67* temperature in my man cave to the 100*F and 85% humidity garage.
