Calling B.S. on all these HO alternators

[sundownz Pro Seller]

Glad to see some good information on HO alts put out there... I've had some CRAP high output alternators in the past.

Ive never heard of that brand //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

see EA, they go by the same name. mine was junk and killed itself at idle with no system in the car

you guys that are testing alt output need to full field these things.

just blasting your system or playing a test tone maxed out isnt necessary going to show you max alt output.

regardless, id be interested to see how the dc power alts hold up to my mean green. never had any issues with my mean green, its been a great alt, but man, those dc alts seem like they are onto something fierce.

don't forget that the amperage output gets lower the hotter the windings become. All these pretty graphs that these companies are posting on their sites concerning RPM vs Amperage output do not reference coil temps //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

mechman now rates there alts at a high tempature, i cannot remember what exactly it was but it was WAY up there //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

those big alternators look like ac compressors

EA ftl

He speaks the truth. Rob personally gave me a tour of his shop, and gave me a crash course why his alts do what they do.
Matter of fact rob I have to catch you at a good time to speak about a few things.

And my hood on my crx is always open to be the test subject for your alts.

DC ftw

I don't believe the point of this thread was to ever take a shot at one company, its just Rob is the only one defending HO Alts in this thread.

It seems like he is making a **** good case and I hope to learn more with some of the questions Chris has for him about alts.

Honestly... between Brandon (employee) and myself we have four EA alternators with no problems at all. I'm sure mileage varies as with anything, of course //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I never really had a problem with mine either. Just a simple bearing noise ,replaced works fine. Still was putting out amps and plenty of voltage when bearing was making noises.

See you know what we are all thinking. We cant see what the RPM really is. You cant tell if some one is pressing on the gas. I didnt really look at the belt that close. I'll give you that.

Now doing the test you are saying you are going to do. Temp of Alt, RPM of eninge. And so on. I think you might have alot more costumers.

I dont remember exactly what engine RPM, but alternator RPM was between 2200-2250..


The only reason I didnt have a laser tach on the pulley is I was already holding the camera, and the 2 meters.. I'm not an octopus... Just a tip though, look at the belt in the video CLOSE, if you can see the logo on the belt going past and it's not a blur, that car was at normal idle...

I'll entertain any kind of meaningful discussion of the pro's/con's of high output alternators, and the difference between large alts like Leece Neville, Niehoff, and units like we build.. I have nothing to shy away from..

Are the bigger alts more capable of big numbers, no doubt.. But they are used in TOTALLY different environments and are built to do it for long periods of time.. If you want to get into ratings and BS, Leece Neville is the WORST offender there is for over-rating their alternators.. Their 320 amp unit is rated 320 @ 72°f but your **** lucky to ever see 250 hot..

Like I said in an earlier post, the ONLY reason you all are so skeptical is because there are so many shady companies making BS claims and not backing them up that when something like this comes up your first instinct is to call BULLSH*T... It's like the boy who cried wolf, many times he cried wolf, and many times there was no wolf, so when he did cry wolf when there WAS a wolf, nobody believed him...

Did you ever think that maybe, just maybe in the last few years that alternator technology, and increases in efficiency has become such that alternators that will do 200 amps at idle ARE possible?? I got one word for you folks, efficiency, efficiency, efficiency....

I have the video of one of these on the test bench that was shot with 2 tachometers, 2 voltmeters, and 2 ammeters that all say the same thing.. And if anyone doesnt believe me after I upload that, then like I said earlier the doors always open for you to come see it yourself...

I have a 300a MechMan alt on my Explorer and my brother has a pair of MechMan 300s on his Excursion. All three included a dyno sheet showing what they can do at a given alt rpm. I'm too lazy to convert it though. I have clamped my alt and got 280a at 1500 engine rpms.

This alt was purchased for the purpose of keeping my amps fed for demo sessions & while competing and it does a great job. I don't need to understand how it does it just know that it does.

mine was rated for 200 amps max. it did 158 at 6k alt rpm ice cold. i would mabye see 120 hot at 6k alt rpm. i think it did something like 67 amps at idle.

$300 gone

Feel free to comment, I'm sure there will be many...
