High output alternators for 5th Gen?

[enginerd4ni]

I've had my eye on this one for a while:
270XP

I think it is the one that [MENTION=83083]rigtec[/MENTION] refers to in his excellent thread. Whether a particular rig needs the extra amperage is up to that rig's design requirements. I'm glad there has been good mention of the need to properly upgrade the wiring.

Hi enginerd4ni,

Yes, that "Nations Starter & Alternator 270-XP" is the one that I installed in my truck... It's everything that it's promised to be and more! For those of you who have attempted to order the 270xp from DC Power Engineering or Nations Starter & Alternator, only to find that their parts catalog only goes up to the 2009 4Runner, that is a neglectful mistake on the company's part; I called them last week and spoke to the owner (Adam) and made him aware of the problem. The part# for ALL 5'th generation 4Runner's is: NSA-11517-270XP, this will drop right in the factory generator's mounting spot, Best to you!

Hi enginerd4ni,

I've decided to post a 'community member endorsement' here so you'll have a little more than just my opinion and flapping gums to give you an idea about the quality of this product. A 270-XP forum member statement This item is very expensive; $630 dollars plus, so I think you should do your homework to see what it's all about, which I've done myself before dropping that kind of loot for a new alternator. But... There are sooo many hopped-up stock alternators out there 'claiming' to develop 200, 300, 390 amps out there, how are you supposed to know which will work the best? If you knew what has to happen to double or triple an alternator's output, then you could fully appreciate what the makers of the 270-XP have done.

Most of these... 'alternator hopper-uppers' believe that you can just overwind the stator, the rotor, install a cheap regulator from China and ship it out. What most of them don't do though is increase the alternator's end-frame and heatsink surface area; if you increase the generator's output you must increase the unit's cooling system capacity, heatsink area, cooling fan's size or pitch, air ventilation system and it's ability to reject heat or you're going to cook it! I'll leave you with just one more link that (I believe) has a volume of important information: https://www.dcpowerinc.com/articles/truth-about-idle

rig, cheers!

Now that’s an awesome alternator!

High output alternator

Is this a good upgrade for running a 12V 6 hp Warn 9.5XP Winch? That winch supposedly draws up to 480 amps at maximum pull weight. Specs here:

I might do this. Do I want, need or benefit from a 2nd battery for the winch if I did?

I'm going to read the wiring upgrade listed above next.

So many mods, so little time. :yo:

A second battery is definitely a benefit when winching if you're doing long pulls

Agree

Just make sure the ACR or combine-switch you are using is capable of pulling the current though it if you go that route.

It won't be the full load, but its going to be significant if ur pulling 480 amps... and its going to be even worse if your winch is connected to the house battery (opposite the alternator) as you will have winch and charge currents passing though the ACR/Switch/Relay.

Some great alternator upgrade info in this thread, DC Power Engineering 270A Alternator Group Buy
I can say I've not had a want for power at all since installing it and the big-3 upgrade.

Alternator, battery and ...

Thanks for the feedback you guys. I'll check out those links and read up on the three upgrades.

So the oem 4awg wire from alternator to battery is not fused on my 2016..

Also I did the big 3 upgrade, 2/0 ground from battery to frame and frame to engine, and 2/0 from battery to alternator.

I got rid of the oem alternator and got a mechman 260amp alternator with a smaller pulley so it outputs that 260 at 1200rpm.

I also added a diode to my fuse labeled agm I think, it boosted my alternator output voltage from 13.5 on a good day to 14.5

In the engine bay I have 2 lifpo4 100amp zoom batteries one in stock location, one next to the firewall on the passenger side (it's almost a better location for a battery than stock.

In the back I have 4 more of those lithium 100amp batteries. And 4 1/0 awg cables run from the engine compartment to the back batteries for charging.

Next to those I have (8) 15" skar audio zvx v2 subs powered by (2) sundown audio 5000w amp and (2) four channel 800 watt sundown audio amps for my mid bass, mid range and tweeters.

I like the mechman alternator but it was a 4 week wait for them to make it, and I'm pulling my hair out looking for a place to squeeze in a second alternator.. maybe mounted on the bottom side of the motor, or extending of the other alternator and adding a second pulley to the first and a short belt from one alternator to the second.. I'll keep you updated if I figure out the second alternator

260 amp was the highest mechman recommended on a daily driver, they told me the 400amp would cause really rough idle and I would feel the alternator drag on the motor power, and since this motor is so slow already...
